Golang : Set or Add HTTP Request Headers



Tags : golang header set add http-request http-client

Problem :

While coding the tutorial on how to interface with PayPal, I need to add header value for Content-Type before posting to PayPal. How to Set or Add HTTP Request Headers?

Solution :

Header (http://golang.org/pkg/net/http/#Header) has Add() and Set() methods.

Example 1:

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

Example 2:

 // post data back to PayPal
 client := &http.Client{}
 req, err := http.NewRequest("POST", postStr, nil)

 if err != nil {
  fmt.Println(err)
  return
 }

 req.Header.Add("Content-Type: ", "application/x-www-form-urlencoded")
 resp, err := client.Do(req)
