We currently support binding of JSON, XML, YAML and standard form values (foo=bar&boo=baz). + +Gin uses [**go-playground/validator/v10**](https://github.com/go-playground/validator) for validation. Check the full docs on tags usage [here](https://godoc.org/github.com/go-playground/validator#hdr-Baked_In_Validators_and_Tags). Note that you need to set the corresponding binding tag on all fields you want to bind. For example, when binding from JSON, set `json:"fieldname"`. -When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use BindWith. +Also, Gin provides two sets of methods for binding: +- **Type** - Must bind + - **Methods** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`, `BindYAML`, `BindHeader` + - **Behavior** - These methods use `MustBindWith` under the hood. If there is a binding error, the request is aborted with `c.AbortWithError(400, err).SetType(ErrorTypeBind)`. This sets the response status code to 400 and the `Content-Type` header is set to `text/plain; charset=utf-8`. Note that if you try to set the response code after this, it will result in a warning `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`. If you wish to have greater control over the behavior, consider using the `ShouldBind` equivalent method. +- **Type** - Should bind + - **Methods** - `ShouldBind`, `ShouldBindJSON`, `ShouldBindXML`, `ShouldBindQuery`, `ShouldBindYAML`, `ShouldBindHeader` + - **Behavior** - These methods use `ShouldBindWith` under the hood. If there is a binding error, the error is returned and it is the developer's responsibility to handle the request and error appropriately. + +When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use `MustBindWith` or `ShouldBindWith`. -You can also specify that specific fields are required. If a field is decorated with `binding:"required"` and has a empty value when binding, the current request will fail with an error. +You can also specify that specific fields are required.

validator implements value validations for structs and individual fields based on tags. + +It has the following **unique** features: + +- Cross Field and Cross Struct validations by using validation tags or custom validators. +- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated. +- Ability to dive into both map keys and values for validation +- Handles type interface by determining it's underlying type prior to validation. +- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29) +- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs +- Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError +- Customizable i18n aware error messages. +- Default validator for the [gin](https://github.com/gin-gonic/gin) web framework; upgrading from v8 to v9 in gin see [here](https://github.com/go-playground/validator/tree/master/_examples/gin-upgrading-overriding) + +Installation +------------ + +Use go get. + + go get github.com/go-playground/validator/v10 + +Then import the validator package into your own code. + + import "github.com/go-playground/validator/v10" + +Error Return Value +------- + +Validation functions return type error + +They return type error to avoid the issue discussed in the following, where err is always != nil: + +* http://stackoverflow.com/a/29138676/3158232 +* https://github.com/go-playground/validator/issues/134 + +Validator only InvalidValidationError for bad validation input, nil or ValidationErrors as type error; so, in your code all you need to do is check if the error returned is not nil, and if it's not check if error is InvalidValidationError ( if necessary, most of the time it isn't ) type cast it to type ValidationErrors like so: + +```go +err := validate.Struct(mystruct) +validationErrors := err.(validator.ValidationErrors) + ``` + +Usage and documentation +------ + +Please see https://godoc.org/github.com/go-playground/validator for detailed usage docs. + +##### Examples: + +-

It works in concert with the Go source code generated -for .proto files by the protocol compiler. - -A summary of the properties of the protocol buffer interface -for a protocol buffer variable v: - - - Names are turned from camel_case to CamelCase for export. - - There are no methods on v to set fields; just treat - them as structure fields. - - There are getters that return a field's value if set, - and return the field's default value if unset. - The getters work even if the receiver is a nil message. - - The zero value for a struct is its correct initialization state. - All desired fields must be set before marshaling. - - A Reset() method will restore a protobuf struct to its zero state. - - Non-repeated fields are pointers to the values; nil means unset. - That is, optional or required field int32 f becomes F *int32. - - Repeated fields are slices. - - Helper functions are available to aid the setting of fields. - msg.Foo = proto.String("hello") // set field - - Constants are defined to hold the default values of all fields that - have them. They have the form Default_StructName_FieldName. - Because the getter methods handle defaulted values, - direct use of these constants should be rare. - - Enums are given type names and maps from names to values. - Enum values are prefixed by the enclosing message's name, or by the - enum's type name if it is a top-level enum. Enum types have a String - method, and a Enum method to assist in message construction. - - Nested messages, groups and enums have type names prefixed with the name of - the surrounding message type. - - Extensions are given descriptor names that start with E_, - followed by an underscore-delimited list of the nested messages - that contain it (if any) followed by the CamelCased name of the - extension field itself. HasExtension, ClearExtension, GetExtension - and SetExtension are functions for manipulating extensions. - - Oneof field sets are given a single field in their message, - with distinguished wrapper types for each possible field value. - - Marshal and Unmarshal are functions to encode and decode the wire format. - -When the .proto file specifies `syntax="proto3"`, there are some differences: - - - Non-repeated fields of non-message type are values instead of pointers. - - Enum types do not get an Enum method. - -The simplest way to describe this is to see an example. -Given file test.proto, containing - - package example;

The method or field name has to be [exported](https://golang.org/ref/spec#Exported_identifiers) and match the schema's field's name in a non-case-sensitive way. +You can use struct fields as resolvers by using `SchemaOpt: UseFieldResolvers()`. For example, +``` +opts := []graphql.SchemaOpt{graphql.UseFieldResolvers()} +schema := graphql.MustParseSchema(s, &query{}, opts...) +``` + +When using `UseFieldResolvers` schema option, a struct field will be used *only* when: +- there is no method for a struct field +- a struct field does not implement an interface method +- a struct field does not have arguments + +The method has up to two arguments: + +- Optional `context.Context` argument. +- Mandatory `*struct { ... }` argument if the corresponding GraphQL field has arguments. The names of the struct fields have to be [exported](https://golang.org/ref/spec#Exported_identifiers) and have to match the names of the GraphQL arguments in a non-case-sensitive way. + +The method has up to two results: + +- The GraphQL field's value as determined by the resolver. +- Optional `error` result. + +Example for a simple resolver method: + +```go +func (r *helloWorldResolver) Hello() string { + return "Hello world!" +} +``` + +The following signature is also allowed: + +```go +func (r *helloWorldResolver) Hello(ctx context.Context) (string, error) { + return "Hello world!", nil +} +``` + +### Schema Options + +- `UseStringDescriptions()` enables the usage of double quoted and triple quoted. When this is not enabled, comments are parsed as descriptions instead. +- `UseFieldResolvers()` specifies whether to use struct field resolvers. +- `MaxDepth(n int)` specifies the maximum field nesting depth in a query. The default is 0 which disables max depth checking. +- `MaxParallelism(n int)` specifies the maximum number of resolvers per request allowed to run in parallel. The default is 10. +- `Tracer(tracer trace.Tracer)` is used to trace queries and fields. It defaults to `trace.OpenTracingTracer`. +- `ValidationTracer(tracer trace.ValidationTracer)` is used to trace validation errors. It defaults to `trace.NoopValidationTracer`. +- `Logger(logger log.Logger)` is used to log panics during query execution. It defaults to `exec.DefaultLogger`. +- `PanicHandler(panicHandler errors.PanicHandler)` is used to transform panics into errors during query execution.

Then, you can use it to make GraphQL queries and mutations. + +```Go +client := graphql.NewClient("https://example.com/graphql", nil) +// Use client... +``` + +### Authentication + +Some GraphQL servers may require authentication. The `graphql` package does not directly handle authentication. Instead, when creating a new client, you're expected to pass an `http.Client` that performs authentication. The easiest and recommended way to do this is to use the [`golang.org/x/oauth2`](https://golang.org/x/oauth2) package. You'll need an OAuth token with the right scopes. Then: + +```Go +import "golang.org/x/oauth2" + +func main() { + src := oauth2.StaticTokenSource( + &oauth2.Token{AccessToken: os.Getenv("GRAPHQL_TOKEN")}, + ) + httpClient := oauth2.NewClient(context.Background(), src) + + client := graphql.NewClient("https://example.com/graphql", httpClient) + // Use client... +``` + +### Simple Query + +To make a GraphQL query, you need to define a corresponding Go type. + +For example, to make the following GraphQL query: + +```GraphQL +query { + me { + name + } +} +``` + +You can define this variable: + +```Go +var query struct { + Me struct { + Name graphql.String + } +} +``` + +Then call `client.Query`, passing a pointer to it: + +```Go +err := client.Query(context.Background(), &query, nil) +if err != nil { + // Handle error. +} +fmt.Println(query.Me.Name) + +// Output: Luke Skywalker +``` + +### Arguments and Variables + +Often, you'll want to specify arguments on some fields. You can use the `graphql` struct field tag for this. + +For example, to make the following GraphQL query: + +```GraphQL +{ + human(id: "1000") { + name + height(unit: METER) + } +} +``` + +You can define this variable: + +```Go +var q struct { + Human struct { + Name graphql.String + Height graphql.Float `graphql:"height(unit: METER)"` + } `graphql:"human(id: \"1000\")"` +} +``` + +Then call `client.Query`: + +```Go +err := client.Query(context.Background(), &q, nil) +if err != nil { + // Handle error. +} +fmt.Println(q.Human.Name) +fmt.Println(q.Human.Height) + +// Output: +// Luke Skywalker +// 1.72 +``` + +However, that'll only work if the arguments are constant and known in advance. Otherwise, you will need to make use of variables. Replace the constants in the struct field tag with variable names: + +```Go +var q struct { + Human struct { + Name graphql.String + Height graphql.Float `graphql:"height(unit: $unit)"` + } `graphql:"human(id: $id)"` +} +``` + +Then, define a `variables` map with their values: + +```Go +variables := map[string]interface{}{ + "id": graphql.ID(id), + "unit": starwars.LengthUnit("METER"), +} +``` + +Finally, call `client.Query` providing `variables`: + +```Go +err := client.Query(context.Background(), &q, variables) +if err != nil { + // Handle error. +} +``` + +### Custom scalar tag + +Because the generator reflects recursively struct objects, it can't know if the struct is a custom scalar such as JSON. To avoid expansion of the field during query generation, let's add the tag `scalar:"true"` to the custom scalar. If the scalar implements the JSON decoder interface, it will be automatically decoded. + +```Go +struct { + Viewer struct { + ID interface{} + Login string + CreatedAt time.Time + DatabaseID int + } +} + +// Output: +// { +// viewer { +// id +// login +// createdAt +// databaseId +// } +// } + +struct { + Viewer struct { + ID interface{} + Login string + CreatedAt time.Time + DatabaseID int + } `scalar:"true"` +} + +// Output +// { viewer } +``` + +### Inline Fragments + +Some GraphQL queries contain inline fragments. You can use the `graphql` struct field tag to express them. + +For example, to make the following GraphQL query: + +```GraphQL +{ + hero(episode: "JEDI") { + name + ... on Droid { + primaryFunction + } + ... on Human { + height + } + } +} +``` + +You can define this variable: + +```Go +var q struct { + Hero struct { + Name graphql.String + Droid struct { + PrimaryFunction graphql.String + } `graphql:"... on Droid"` + Human struct { + Height graphql.Float + } `graphql:"... on Human"` + } `graphql:"hero(episode: \"JEDI\")"` +} +``` + +Alternatively, you can define the struct types corresponding to inline fragments, and use them as embedded fields in your query: + +```Go +type ( + DroidFragment struct { + PrimaryFunction graphql.String + } + HumanFragment struct { + Height graphql.Float + } +) + +var q struct { + Hero struct { + Name graphql.String + DroidFragment `graphql:"... on Droid"` + HumanFragment `graphql:"... on Human"` + } `graphql:"hero(episode: \"JEDI\")"` +} +``` + +Then call `client.Query`: + +```Go +err := client.Query(context.Background(), &q, nil) +if err != nil { + // Handle error. +} +fmt.Println(q.Hero.Name) +fmt.Println(q.Hero.PrimaryFunction) +fmt.Println(q.Hero.Height) + +// Output: +// R2-D2 +// Astromech +// 0 +``` + +### Mutations + +Mutations often require information that you can only find out by performing a query first. Let's suppose you've already done that. + +For example, to make the following GraphQL mutation: + +```GraphQL +mutation($ep: Episode!, $review: ReviewInput!) { + createReview(episode: $ep, review: $review) { + stars + commentary + } +} +variables { + "ep": "JEDI", + "review": { + "stars": 5, + "commentary": "This is a great movie!" + } +} +``` + +You can define: + +```Go +var m struct { + CreateReview struct { + Stars graphql.Int + Commentary graphql.String + } `graphql:"createReview(episode: $ep, review: $review)"` +} +variables := map[string]interface{}{ + "ep": starwars.Episode("JEDI"), + "review": starwars.ReviewInput{ + Stars: graphql.Int(5), + Commentary: graphql.String("This is a great movie!"), + }, +} +``` + +Then call `client.Mutate`: + +```Go +err := client.Mutate(context.Background(), &m, variables) +if err != nil { + // Handle error. +} +fmt.Printf("Created a %v star review: %v\n", m.CreateReview.Stars, m.CreateReview.Commentary) + +// Output: +// Created a 5 star review: This is a great movie! +``` + +#### Mutations Without Fields + +Sometimes, you don't need any fields returned from a mutation. Doing that is easy. + +For example, to make the following GraphQL mutation: + +```GraphQL +mutation($ep: Episode!, $review: ReviewInput!) { + createReview(episode: $ep, review: $review) +} +variables { + "ep": "JEDI", + "review": { + "stars": 5, + "commentary": "This is a great movie!" + } +} +``` + +You can define: + +```Go +var m struct { + CreateReview string `graphql:"createReview(episode: $ep, review: $review)"` +} +variables := map[string]interface{}{ + "ep": starwars.Episode("JEDI"), + "review": starwars.ReviewInput{ + Stars: graphql.Int(5), + Commentary: graphql.String("This is a great movie!"), + }, +} +``` + +Then call `client.Mutate`: + +```Go +err := client.Mutate(context.Background(), &m, variables) +if err != nil { + // Handle error. +} +fmt.Printf("Created a review: %s.\n", m.CreateReview) + +// Output: +// Created a review: . +``` + +### Subscription + +#### Usage + +Construct a Subscription client, specifying the GraphQL server URL. + +```Go +client := graphql.NewSubscriptionClient("wss://example.com/graphql") +defer client.Close() + +// Subscribe subscriptions +// ... +// finally run the client +client.Run() +``` + +#### Subscribe + +To make a GraphQL subscription, you need to define a corresponding Go type. + +For example, to make the following GraphQL query: + +```GraphQL +subscription { + me { + name + } +} +``` + +You can define this variable: + +```Go +var subscription struct { + Me struct { + Name graphql.String + } +} +``` + +Then call `client.Subscribe`, passing a pointer to it: + +```Go +subscriptionId, err := client.Subscribe(&query, nil, func(dataValue *json.RawMessage, errValue error) error { + if errValue != nil { + // handle error + // if returns error, it will failback to `onError` event + return nil + } + data := query{} + err := json.Unmarshal(dataValue, &data) + + fmt.Println(query.Me.Name) + + // Output: Luke Skywalker +}) + +if err != nil { + // Handle error. +} + +// you can unsubscribe the subscription while the client is running +client.Unsubscribe(subscriptionId) +``` + +#### Authentication + +The subscription client is authenticated with GraphQL server through connection params: + +```Go +client := graphql.NewSubscriptionClient("wss://example.com/graphql"). + WithConnectionParams(map[string]interface{}{ + "headers": map[string]string{ + "authentication": "...", + }, + }) + +``` + +#### Options + +```Go +client. + // write timeout of websocket client + WithTimeout(time.Minute). + // When the websocket server was stopped, the client will retry connecting every second until timeout + WithRetryTimeout(time.Minute). + // sets loging function to print out received messages. By default, nothing is printed + WithLog(log.Println). + // max size of response message + WithReadLimit(10*1024*1024). + // these operation event logs won't be printed + WithoutLogTypes(graphql.GQL_DATA, graphql.GQL_CONNECTION_KEEP_ALIVE) + +``` + +#### Events + +```Go +// OnConnected event is triggered when the websocket connected to GraphQL server sucessfully +client.OnConnected(fn func()) + +// OnDisconnected event is triggered when the websocket server was stil down after retry timeout +client.OnDisconnected(fn func()) + +// OnConnected event is triggered when there is any connection error. This is bottom exception handler level +// If this function is empty, or returns nil, the error is ignored +// If returns error, the websocket connection will be terminated +client.OnError(onError func(sc *SubscriptionClient, err error) error) +``` + +#### Custom WebSocket client + +By default the subscription client uses [nhooyr WebSocket client](https://github.com/nhooyr/websocket). If you need to customize the client, or prefer using [Gorilla WebSocket](https://github.com/gorilla/websocket), let's follow the Websocket interface and replace the constructor with `WithWebSocket` method: + +```go +// WebsocketHandler abstracts WebSocket connection functions +// ReadJSON and WriteJSON data of a frame from the WebSocket connection. +// Close the WebSocket connection. +type WebsocketConn interface { + ReadJSON(v interface{}) error + WriteJSON(v interface{}) error + Close() error + // SetReadLimit sets the maximum size in bytes for a message read from the peer. If a + // message exceeds the limit, the connection sends a close message to the peer + // and returns ErrReadLimit to the application. + SetReadLimit(limit int64) +} + +// WithWebSocket replaces customized websocket client constructor +func (sc *SubscriptionClient) WithWebSocket(fn func(sc *SubscriptionClient) (WebsocketConn, error)) *SubscriptionClient +``` + +**Example** + +```Go + +// the default websocket constructor +func newWebsocketConn(sc *SubscriptionClient) (WebsocketConn, error) { + options := &websocket.DialOptions{ + Subprotocols: []string{"graphql-ws"}, + } + c, _, err := websocket.Dial(sc.GetContext(), sc.GetURL(), options) + if err != nil { + return nil, err + } + + // The default WebsocketHandler implementation using nhooyr's + return &WebsocketHandler{ + ctx: sc.GetContext(), + Conn: c, + timeout: sc.GetTimeout(), + }, nil +} + +client := graphql.NewSubscriptionClient("wss://example.com/graphql") +defer client.Close() + +client.WithWebSocket(newWebsocketConn) + +client.Run() +``` + +### Options + +There are extensible parts in the GraphQL query that we sometimes use. They are optional so that we shouldn't required them in the method. To make it flexible, we can abstract these options as optional arguments that follow this interface. + +```go +type Option interface { + Type() OptionType + String() string +} + +client.Query(ctx context.Context, q interface{}, variables map[string]interface{}, options ...Option) error +``` + +Currently we support 2 option types: `operation_name` and `operation_directive`. The operation name option is built-in because it is unique. We can use the option directly with `OperationName` + +```go +// query MyQuery { +// ... +// } +client.Query(ctx, &q, variables, graphql.OperationName("MyQuery")) +``` + +In contrast, operation directive is various and customizable on different GraphQL servers. There isn't any built-in directive in the library. You need to define yourself. For example: + +```go +// define @cached directive for Hasura queries +// https://hasura.io/docs/latest/graphql/cloud/response-caching.html#enable-caching +type cachedDirective struct { + ttl int +} + +func (cd cachedDirective) Type() OptionType { + // operation_directive + return graphql.OptionTypeOperationDirective +} + +func (cd cachedDirective) String() string { + if cd.ttl <= 0 { + return "@cached" + } + return fmt.Sprintf("@cached(ttl: %d)", cd.ttl) +} + +// query MyQuery @cached { +// ... +// } +client.Query(ctx, &q, variables, graphql.OperationName("MyQuery"), cachedDirective{}) +``` + +### With operation name (deprecated) + +Operation name is still on API decision plan https://github.com/shurcooL/graphql/issues/12. However, in my opinion separate methods are easier choice to avoid breaking changes + +```Go +func (c *Client) NamedQuery(ctx context.Context, name string, q interface{}, variables map[string]interface{}) error + +func (c *Client) NamedMutate(ctx context.Context, name string, q interface{}, variables map[string]interface{}) error + +func (sc *SubscriptionClient) NamedSubscribe(name string, v interface{}, variables map[string]interface{}, handler func(message *json.RawMessage, err error) error) (string, error) +``` + +### Raw bytes response + +In the case we developers want to decode JSON response ourself. Moreover, the default `UnmarshalGraphQL` function isn't ideal with complicated nested interfaces + +```Go +func (c *Client) QueryRaw(ctx context.Context, q interface{}, variables map[string]interface{}) (*json.RawMessage, error) + +func (c *Client) MutateRaw(ctx context.Context, q interface{}, variables map[string]interface{}) (*json.RawMessage, error) + +func (c *Client) NamedQueryRaw(ctx context.Context, name string, q interface{}, variables map[string]interface{}) (*json.RawMessage, error) + +func (c *Client) NamedMutateRaw(ctx context.Context, name string, q interface{}, variables map[string]interface{}) (*json.RawMessage, error) +``` + +### Multiple mutations with ordered map + +You might need to make multiple mutations in single query. It's not very convenient with structs +so you can use ordered map `[][2]interface{}` instead. + +For example, to make the following GraphQL mutation: + +```GraphQL +mutation($login1: String!, $login2: String!, $login3: String!) { + createUser(login: $login1) { login } + createUser(login: $login2) { login } + createUser(login: $login3) { login } +} +variables { + "login1": "grihabor", + "login2": "diman", + "login3": "indigo" +} +``` + +You can define: + +```Go +type CreateUser struct { + Login graphql.String +} +m := [][2]interface{}{ + {"createUser(login: $login1)", &CreateUser{}}, + {"createUser(login: $login2)", &CreateUser{}}, + {"createUser(login: $login3)", &CreateUser{}}, +} +variables := map[string]interface{}{ + "login1": graphql.String("grihabor"), + "login2": graphql.String("diman"), + "login3": graphql.String("indigo"), +} +``` + +Directories +----------- + +| Path | Synopsis | +|----------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------| +| [example/graphqldev](https://godoc.org/github.com/shurcooL/graphql/example/graphqldev) | graphqldev is a test program currently being used for developing graphql package. | +| [ident](https://godoc.org/github.com/shurcooL/graphql/ident) | Package ident provides functions for parsing and converting identifier names between various naming convention. | +| [internal/jsonutil](https://godoc.org/github.com/shurcooL/graphql/internal/jsonutil) | Package jsonutil provides a function for decoding JSON into a GraphQL query data structure. | + +References +---------- +- https://github.com/shurcooL/graphql +- https://github.com/apollographql/subscriptions-transport-ws/blob/master/PROTOCOL.md +- https://github.com/nhooyr/websocket + + +License +------- + +- [MIT License](LICENSE) diff --git a/vendor/github.com/hasura/go-graphql-client/doc.go b/vendor/github.com/hasura/go-graphql-client/doc.go new file mode 100644 index 000000000..69ec4e038 --- /dev/null +++ b/vendor/github.com/hasura/go-graphql-client/doc.go @@ -0,0 +1,11 @@ +// Package graphql provides a GraphQL client implementation. +// +// For more information, see package github.com/shurcooL/githubv4, +// which is a specialized version targeting GitHub GraphQL API v4. +// That package is driving the feature development. +// +// Status: In active early research and development.
