关于http:HTTP中request请求参数的设置

在发送的 http 申请中咱们能够定制本人的申请体，上面是几个示例代码

package main

import (
   "fmt"
   "io/ioutil"
   "net/http"
   "net/url"
)

func printBody(r *http.Response){content, err := ioutil.ReadAll(r.Body)
   if err != nil {panic(err)
   }
   fmt.Printf("%s", content)
}

// 设置申请查问参数
func requestByParams(){request, err := http.NewRequest(http.MethodGet, "http://httpbin.org/get", nil)
   if err != nil {panic(err)
   }
   params := make(url.Values)
   params.Add("name", "yuan")
   params.Add("age", "18")
   request.URL.RawQuery = params.Encode()
   fmt.Println(params.Encode())

   resp, err := http.DefaultClient.Do(request)
   if err != nil {panic(err)
   }
   defer func() {_ = resp.Body.Close()}()
   printBody(resp)
   //{
   // "args": {
   //      "age": "18",
   //    "name": "yuan"
   //},
   // "headers": {
   //      "Accept-Encoding": "gzip",
   //    "Host": "httpbin.org",
   //    "User-Agent": "Go-http-client/1.1",
   //    "X-Amzn-Trace-Id": "Root=1-60e46b98-58667aee5367f1aa1ca102c9"
   //},
   // "origin": "222.211.214.252",
   // "url": "http://httpbin.org/get?age=18&name=yuan"
   //}
}

// 定制申请头
func reauestByHead(){request, err := http.NewRequest(http.MethodGet, "http://httpbin.org/get", nil)
   if err != nil {panic(err)
   }
   request.Header.Add("user-agent", "chrome")
   resp, err := http.DefaultClient.Do(request)
   if err != nil {panic(err)
   }
   defer func() {_ = resp.Body.Close()}()
   printBody(resp)
   //{// "args": {},
   // "headers": {
   //      "Accept-Encoding": "gzip",
   //    "Host": "httpbin.org",
   //    "User-Agent": "chrome",
   //    "X-Amzn-Trace-Id": "Root=1-60e46c63-22fd52047229e6175f52166c"
   //},
   // "origin": "222.211.214.252",
   // "url": "http://httpbin.org/get"
   //}
}
func main() {requestByParams()
   reauestByHead()}
