Go HTTP Client PUT request of JSON object
Example
The following updates a User object via a PUT request and prints the status code of the request:
package main
import (
"bytes"
"encoding/json"
"fmt"
"net/http"
)
type User struct {
Name string
Email string
}
func main() {
user := User{
Name: "John Doe",
Email: "[email protected]",
}
// initialize http client
client := &http.Client{}
// marshal User to json
json, err := json.Marshal(user)
if err != nil {
panic(err)
}
// set the HTTP method, url, and request body
req, err := http.NewRequest(http.MethodPut, "http://api.example.com/v1/user", bytes.NewBuffer(json))
if err != nil {
panic(err)
}
// set the request header Content-Type for json
req.Header.Set("Content-Type", "application/json; charset=utf-8")
resp, err := client.Do(req)
if err != nil {
panic(err)
}
fmt.Println(resp.StatusCode)
}
