go http.NewRequest用法

client := &http.Client{Timeout: 30 * time.Second, Transport: tr}
**//http不需要证书验证，直接写**
//client := &http.Client
reqUser := bytes.NewReader(userNew)
**//POST 请求需要加参数**
req, _ := http.NewRequest("POST", urlSign, reqUser)
**//GET 请求**
//req, _ := http.NewRequest("GET", urlSign, nil)
**//可以添加多个头部**
req.Header.Set("Content-Type", "application/json")

**//可以根据repBody的数据类型获取数据**
//string

//map
