Why should you use GoRequest?

GoRequest makes thing much more simple for you, making http client more awesome and fun like SuperAgent + golang style usage.

This is what you normally do for a simple GET without GoRequest:

resp, err := http.Get("http://example.com/")

With GoRequest:

request := gorequest.New()
resp, body, err := request.Get("http://example.com/").End()

Or below if you don't want to reuse it for other requests.

resp, body, err := gorequest.New().Get("http://example.com/").End()

How about getting control over HTTP client headers, redirect policy, and etc. Things is getting more complicated in golang. You need to create a Client, setting header in different comamnd, ... to do just only one GET

client := &http.Client{
  CheckRedirect: redirectPolicyFunc,
}

req, err := http.NewRequest("GET", "http://example.com", nil)

req.Header.Add("If-None-Match", `W/"wyzzy"`)
resp, err := client.Do(req)

Why making things ugly while you can just do as follows:

request := gorequest.New()
resp, body, err := request.Get("http://example.com").
  RedirectPolicy(redirectPolicyFunc).
  Set("If-None-Match", `W/"wyzzy"`).
  End()

For a JSON POST with standard libraries, you might need to marshal map data structure to json format, setting header to 'application/json' (and other headers if you need to) and declare http.Client. So, you code become longer and hard to maintain:

m := map[string]interface{}{
  "name": "backy",
  "species": "dog",
}
mJson, _ := json.Marshal(m)
contentReader := bytes.NewReader(mJson)
req, _ := http.NewRequest("POST", "http://example.com", contentReader)
req.Header.Set("Content-Type", "application/json")
req.Header.Set("Notes","GoRequest is coming!")
client := &http.Client{}
resp, _ := client.Do(req)

Compared to our GoRequest version, JSON is for sure a default. So, it turns out to be just one simple line!:

request := gorequest.New()
resp, body, err := request.Post("http://example.com").
  Set("Notes","gorequst is coming!").
  Send(`{"name":"backy", "species":"dog"}`).
  End()

Note: This is a work in progress and not totally support all specifications. Right now, you can do simple get and post with easy to specify header like in examples which is enough in many cases.
