在发送的http请求中我们可以定制自己的请求体，下面是几个示例代码
package mainimport ("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)}//设置请求查询参数func requestByParams(){request, err := http.NewRequest(http.MethodGet, "/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": "",// "User-Agent": "Go-http-client/1.1",// "X-Amzn-Trace-Id": "Root=1-60e46b98-58667aee5367f1aa1ca102c9"//},// "origin": "222.211.214.252",// "url": "/get?age=18&name=yuan"//}}//定制请求头func reauestByHead(){request, err := http.NewRequest(http.MethodGet, "/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": "",// "User-Agent": "chrome",// "X-Amzn-Trace-Id": "Root=1-60e46c63-22fd52047229e6175f52166c"//},// "origin": "222.211.214.252",// "url": "/get"//}}func main() {requestByParams()reauestByHead()}
