Go net/http包,原生http客戶端使用
-
http包提供的兩個快速Get,Post請求的函式定義如下(go不支持函式多載)
-
func Get(url string) (resp *Response, err error)
-
func Post(url, contentType string, body io.Reader) (resp *Response, err error)
-
func PostForm(url string, data url.Values) (resp *Response, err error)
PostForm 是contenType值為 application/x-www-form-urlencoded 時的Post
-
-
要管理HTTP客戶端的頭域、重定向策略和其他設定，需自定義Client
-
要管理代理、TLS配置、keep-alive、壓縮和其他設定，需自定義Transport
簡單get/post請求的代碼
package main
import (
"bytes"
"encoding/json"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
params := url.Values{}
params.Set("password", "zhaofan")
GetWithParam("http://10.93.181.200:8090/sh/encrypt", params)
//
data := make(map[string]interface{})
data["id"] = "1"
data["name"] = "博客"
Post("http://10.93.181.200:8090/sh/json", data)
}
// 無請求頭,無引數get
func Get(urlStr string) {
res, _ := http.Get(urlStr)
defer res.Body.Close()
bodyBytes, _ := ioutil.ReadAll(res.Body)
body := string(bodyBytes)
fmt.Print(body)
}
// 無請求頭, 有引數get
func GetWithParam(urlStr string, params url.Values) {
Url, _ := url.Parse(urlStr)
Url.RawQuery = params.Encode()
urlPath := Url.String()
// 列印拼接后的url, 形如https://www.xxx.com?k=v&k2=v2
fmt.Println(urlPath)
resp, _ := http.Get(urlPath)
defer resp.Body.Close()
bodyBytes, _ := ioutil.ReadAll(resp.Body)
body := string(bodyBytes)
fmt.Println(string(body))
}
// 帶json引數的post請求
func Post(urlStr string, v interface{}) {
bytesData, _ := json.Marshal(v)
resp, _ := http.Post(urlStr, "application/json", bytes.NewReader(bytesData))
defer resp.Body.Close()
bodyBytes, _ := ioutil.ReadAll(resp.Body)
body := string(bodyBytes)
fmt.Println(body)
}
