GoRequest

What is GoRequest?

"Simplified HTTP Request" library for Golang
Node.js SuperAgent style
771 stars, 99 forks, used by 77 packages

Basic Get Request in Go


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

How about JSON POST in Go?


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

(Things get more complicated.)

Node.js Superagent


request
 .post('http://example.com')
 .send({ name: 'backy', species: 'dog' })
 .set('Notes', 'Superagent is coming!')
 .end(function(err, res){
   if (err || !res.ok) {
     alert('Oh no! error');
   } else {
     alert('yay got ' + JSON.stringify(res.body));
   }
 });

GoRequest to Rescue

Look back on Go's JSON POST


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

GoRequest's JSON POST


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