http

使用 http.Client

1. GET

   package main
   
   import (
     "io/ioutil"
     "net/http"
     "time"
   )
   
   func Get(url string) string{
       client := &http.Client{}
       resp, err := client.Get(url)
       if err != nil {
           panic(err)
       }
   
       // 读取 body
       defer resp.Body.Close()
       body, err := ioutil.ReadAll(resp.Body)
   }
   

常用操作

1. 设置超时时间

   // 设置 5s 超时时间
   client := &http.Client{Timeout: 5*time.Second}
   

2. 设置 header

   // 需要使用 http.NewRequest
   client := &http.Client{}
   req, err := http.NewRequest("POST", url, bytes.NewReader(jsonStr))
   req.Header.Add("Content-Type", "application/json")
   resp, err := client.Do(req)
