as mentioned here #1 , please see the todo example. It currently gives error for introspection query

{
  "error": {
    "message": "parser: malformed graphql operation: 1:1 (0): no match found"
  }
}

@bsr203 thanks for this contribution, let's get this working. Which introspection query are you referring to?

[bsr203]

well, I just tested the existing example

e/basic_graphql_server ❯❯❯ go run main.go                                                                                                     master
2015/11/04 15:19:34 query: 
2015/11/04 15:19:34 error parsing: parser: malformed graphql operation: 1:1 (0): no match found
2015/11/04 15:19:36 query: 
2015/11/04 15:19:36 error parsing: parser: malformed graphql operation: 1:1 (0): no match found
2015/11/04 15:19:38 query: 
2015/11/04 15:19:38 error parsing: parser: malformed graphql operation: 1:1 (0): no match found
2015/11/04 15:19:48 query: 

which also gives the same error. I was using graphiql

may be please explain to me how do you test, basic_graphiql_example, I will get the introspection query in just bit

Edit:

for the todo app, the viewer query was failing

{"query":"query ViewerQueries{viewer{id,...__RelayQueryFragment0xh4pba}} fragment __RelayQueryFragment16p69yi on User{id,totalCount} fragment __RelayQueryFragment39q7490 on TodoConnection{edges{node{complete,id},cursor},pageInfo{hasNextPage,hasPreviousPage}} fragment __RelayQueryFragment4w5m15t on User{completedCount,id,totalCount} fragment __RelayQueryFragment2gl3aeh on User{completedCount,_todosa8fgf3:todos(status:\"completed\",first:9007199254740991){...__RelayQueryFragment39q7490},totalCount,id,...__RelayQueryFragment4w5m15t} fragment __RelayQueryFragment0xh4pba on User{totalCount,id,...__RelayQueryFragment16p69yi,...__RelayQueryFragment2gl3aeh}","variables":{}}

Will look further

[bsr203]

I was trying like

basic_graphql_server ❯❯❯ curl -XPOST -H "Content-Type:application/graphql"  -d 'query nowProvider { now }' http://localhost:8080            master
{"error":{"message":"parser: malformed graphql operation: 1:1 (0): no match found"}}

I am not sure about how the schema looks like, without seeing the json or graphiql. Can you please let me know how to run proper query in basic_graphql_server example. Also, is there a way to dump introspection query to use with relay

for example, this query fails

basic_graphql_server ❯❯❯ curl -XPOST  -d '{ __schema{ types {  name } } }'  http://localhost:8080                                           master
{"error":{"message":"parser: malformed graphql operation: 1:1 (0): no match found"}}

which works fine at http://goo.gl/6p6PdN

Edit:

found the correct query should have been

curl -sgG --data-urlencode "q={ __schema{ types { name } } }" http://localhost:8080/

from cgraphqli.sh script

and this works

 curl -sgG --data-urlencode "q={ now }" http://localhost:8080/                                                                       master
{
  "data": [
    "2015-11-04T16:16:06.51128663-05:00"
  ]
}%                                                   

still digging.

Hi,
one issue of using with graphiql, etc that currently handler doesn't accept POST request. I saw from the doc that it is given as an example, so I may extend it. So, made some more progress by allowing POST request like

type Response struct {
    Query string `json:"query"`
}

//TODO(tmc): reject non-GET/OPTIONS requests
//TODO(bsr203) allow POST ?
func getQuery(r *http.Request) string {
    if r.Method != "POST" {
        q := r.URL.Query().Get("q")
        if q == "" {
            q = r.URL.Query().Get("query")
        }
        return q
    }
    body, err := ioutil.ReadAll(r.Body)
    if err != nil {
        panic(err) //TODO
    }
    var resp Response
    json.Unmarshal([]byte(body), &resp)
    return resp.Query
}

...

q := getQuery(r)
    log.Println("query:", q)

...

further, for the below introspection query from graphiql, I got error

2015/11/04 16:45:28 query: 
  query IntrospectionQuery {
    __schema {
      queryType { name }
      mutationType { name }
      types {
        ...FullType
      }
      directives {
        name
        description
        args {
          ...InputValue
        }
        onOperation
        onFragment
        onField
      }
    }
  }

  fragment FullType on __Type {
    kind
    name
    description
    fields {
      name
      description
      args {
        ...InputValue
      }
      type {
        ...TypeRef
      }

      deprecationReason
    }
    inputFields {
      ...InputValue

    interfaces {
      ...TypeRef
    }
    enumValues {
      name
      description
      isDeprecated
      deprecationReason
    }
    possibleTypes {
      ...TypeRef
    }
  }

  fragment InputValue on __InputValue {
    name
    description
    type { ...TypeRef }
    defaultValue
  }

  fragment TypeRef on __Type {
    kind
    name
    ofType {
      kind
      name
      ofType {
        kind
        name
        ofType {
          kind
          name
        }
      }
    }
  }

error: {message: "No handler for field 'queryType' on type '*schema.Schema'"}

@tmc I am not sure the implementation in this pull request is the best to follow. There are types defined for mutation, connection, ... and may unnecessary. I don't see all the root queries on viewer. Also, user has many fields (looks like all root fields).Invoking all the handlers through graph/schema also cause Graph type to explode

func (graph *Graph) GraphQLTypeInfo() schema.GraphQLTypeInfo {
+   return schema.GraphQLTypeInfo{
...
todo := graph.AddToDo(graph.Users["me"], input["text"].(string), false)
..
}

I would probably directly call my domain handlers from schema.

so, please treat it just an idea and anxious to see how you approach it.

Please give some pointers and I try to build on it.

Cheers.

@tmc Hi Travis. Any time for this :-)
