import ( "net/http" "net/url")data := url.Values{"start":{"100"}, "hobby":{"xxxx"}}body := strings.NewReader(data.Encode())resp, err := http.Post("127.0.0.1:9338", "application/x-www-form-urlencoded", body) |
net/http包没有封装直接使用请求带header的get或者post方法，所以，要想请求中带header，只能使用NewRequest方法
http.NewRequest
客户端：

import ( "net/http" "json" "ioutil")type Student struct{ id string name string}type StudentReq struct{ id string name string}func main() { stu := Student{ id:"2ed4tg5fe35fgty3yy6uh", name:"amber", } stu,err := json.Marshal(&stu) reader := bytes.NewReader(stu) request,err := http.NewRequest("POST", "http://192.168.1.12:8000/create", reader) request.Header.Set("Content-Type", "application/json") client:=&http.Client{} response,err := client.Do(request) defer response.Body.Close() body,err := ioutil.ReadAll(response.Body) fmt.Printf(string(body)) var stuReq StudentReq err = json.UnMarshal(body, &stuReq) fmt.Println(json.MarshalIndent(stuReq))} |
解析：
- stu,err := json.Marshal(&stu)：将stu对象改为json格式
- reader := bytes.NewReader(stu)：所以将json改为byte格式，作为body传给http请求
- request,err := http.NewRequest(“POST”, “http://192.168.1.12:8000/create”, reader)：创建url
- response,err := client.Do(request)：客户端发起请求，接收返回值
- body,err := ioutil.ReadAll(response.Body)：读取body的值，类型是byte
- json.MarshalIndent(stuReq)：修改json为标准格式
注意（坑）：
1、header里的参数是Content-Type，不要写成ContentType
2、【go http: read on closed response body 】如果发送的请求是分为2个func写的，记住defer要在ioutil.ReadAll之后执行，否则报错
gorequest
这种方式适合在url里拼接参数使用param直接传递
