A simple to use golang http client


  • Easy to set HTTP Headers
  • Query strings can be added through key-value pairs or struct easily
  • Extend url path whenever you want
  • Send form and json data in one line
  • Basic Auth right away
  • Read from response the easy way
  • Support proxy configuration
  • Allow set timeout at all levels
  • Automatically retry request, if you let it
  • Custom redirect policy
  • Perform hook functions
  • Session support, persistent response data, and reuse them in next request
  • More to come ...


  • Simple: the exposed interface should be simple and intuitive. After all, this is why gohttp is created
  • Consistent: Derived from net/http, gohttp tries to keep consistent with it as much as possible
  • Fully-Documented: along with the simple interface, documents and examples will be given to demostrate the full usage, pitfalls and best practices


go get

And then import the package in your code:

import ""


Get a resource from url

gohttp provides shortcut to make simple GET quite straightforward:

resp, err := gohttp.Get("")

The above does the same thing as:

resp, err := gohttp.New().Get("")

In fact, this is exactly what it does behind the scene. gohttp.New() returns gohttp.Client struct, which gives you full control of the request which be sent.

Create url path on the fly

If url path can not decided until runtime or you want it be flexible, Path() method is here to help:

resp, err := gohttp.New().Path("/repos").Path("cizixs/gohttp/").Path("issues").Get("")

Or simply in one method:

resp, err := gohttp.New().Path("/repos", "cizixs/gohttp/", "issues").Get("")

Notice how gohttp handles the slash / appropriately no matter where it is placed(or not placed at all).

Pass arguments(query string) in URLs

There are often times you want to include query strings in url, handling this issue manually can be tiresome and boring. Not with gohttp:

gohttp.New().Path("/repos", "cizixs/gohttp/", "issues").
    Query("state", "open").Query("sort", "updated").Query("mentioned", "cizixs").

Think this is tedious too? Here comes the better part, you can pass a struct as query strings:

type issueOption struct {
	State     string `json:"state,omitempty"`
	Assignee  string `json:"assignee,omitempty"`
	Creator   string `json:"creator,omitempty"`
	Mentioned string `json:"mentioned,omitempty"`
	Labels    string `json:"labels,omitempty"`
	Sort      string `json:"sort,omitempty"`
	Rirection string `json:"direction,omitempty"`
	Since     string `json:"since,omitempty"`

i := &issueOption{
	State:     "open",
	Mentioned: "cizixs",
	Sort:      "updated",
resp, err := gohttp.New().Path("/repos", "cizixs/gohttp/", "issues").QueryStruct(i).Get("")

Custom Headers

gohttp.New().Header(key, value).Header(key, value).Get(url)

Or, simply pass all headers in a map:


Post and PUT

Not only GET is simple, gohttp implements all other methods:

body := strings.NewReader("hello, gohttp!")

NOTE: The actual data sent is based on HTTP method the request finally fires. Anything not compliant with that METHOD will be ommited. For example, set data to a GET request has no effect, because it will not be used at all.

Post all kinds of data

When comes to sending data to server, POST might be the most frequently used method. Of all user cases, send form data and send json data comes to the top. gohttp tries to make these actions easy:

// send Form data
gohttp.New().Form("username", "cizixs").Form("password", "secret").Post("")

// send json data
gohttp.New().Json(`{"Name":"Cizixs"}`).Post(url)         // use a marshalled json string

struct User{
    Name string `json:"name,omitempty"`
    Age int `json:"age,omitempty"`

user := &User{Name: "cizixs", Age: 22}
gohttp.New().JsonStruct(user).Post(url)   // use a struct and parse it to json

Basic Auth

gohttp.New().BasicAuth("username", "password").Get("")


By default, net/http does not have timeout, will wait forever until response is returned. This can be a serious issue if server hangs, gohttp allows you to set a timeout limit, if response does not finish in time, an error will be returned.



Error happens! gohttp provides retry mechanism to automatically resend request when error happens. This is useful to avoid some unstable error like network temporary failure:


By default, request is only sent only and all. If custom retry is set to less than one, default behavior will be used. The retry condition only means response error, not including 5XX error.

Upload file(s)

Upload files is simple too, multiple files can be uploaded in one request.

f, _ := os.Open(filePath)
gohttp.New().File(f io.Reader, "filename", "fieldname").Post(url)


If you are sending request behind a proxy, you can do this:



Access cookie from response is simple:

cookies := resp.Cookies()

gohttp.New().Cookie(cookie *http.Cookie).Cookie(cookie *http.Cookie).Get(url)

Response data as string

If the response contains string data, you can read it by:

resp, _ := gohttp.New().Get("")
data, _ := resp.AsString()

Response data as bytes

If the response contains raw bytes, you can read it by:

resp, _ := gohttp.New().Get("")
data, _ := resp.AsBytes()

Response data as json struct

If the response contains json struct, you can pass a struct to it, and gohttp will marshall it for you:

user := &User{}
resp, _ := gohttp.New().Get("")
err := resp.AsJSON(user)

Reuse client

When developing complicated http client applications, it is common to interact with one remote server with some common settings, like url, basic auth, custom header, etc. gohttp provides New method for this kind of situation.

As stated in document:

New clones current client struct and returns it. This is useful to initialize some common parameters and send different requests with differenet paths/headers/timeout/retries...

For example:

c := gohttp.New().URL("")
c.BasicAuth("cizixs", "mypassword")
c.Timeout(3 * time.Second)
users, err := c.New().Path("/users/").Get()
repos, err := c.New().Path("/repos").Get()

Note: files, body and cookies value are copied so that if pointer value is used, base client and cloned client(s) will share the same instance, change on one side will take effect on the other side, and this might not as expected.

Debug mode

When developing http apps, it is often necessary to know the actual request and response sent for debugging or testing purpose. gohttp provides debug mode, which can be turned on by environment variable GOHTTP_DEBUG or Debug(bool) method:

resp, _ := gohttp.New().Debug(true).Get("")

In debug mode, gohttp will print out each request and response in human-readble format.

A typical request:

User-Agent: Go-http-client/1.1
Content-Length: 39
Content-Type: application/json
Accept-Encoding: gzip

{"title":"Test title","name":"cizixs"}

A typical response:

2016/11/29 18:30:59 HTTP/1.1 200 OK
Content-Length: 39
Content-Type: application/json; charset=utf-8
Date: Tue, 29 Nov 2016 10:30:59 GMT
