golang post请求常用的几种方式小结

post请求常用的几种方式，记录一下

func httpPost() {
    resp, err := http.Post("https://www.abcd123.top/api/v1/login",
        "application/x-www-form-urlencoded",
        strings.NewReader("username=test&password=ab123123"))
    if err != nil {
        fmt.Println(err)
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        // handle error
    }
    fmt.Println(string(body))
}
func httpPostForm() {
    resp, err := http.PostForm("https://www.denlery.top/api/v1/login",
        url.Values{"username": {"auto"}, "password": {"auto123123"}})
    if err != nil {
        // handle error
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        // handle error
    }
    fmt.Println(string(body))
}
func httpPostJson() {
    jsonStr :=[]byte(`{ "username": "auto", "password": "auto123123" }`)
    url:= "https://www.denlery.top/api/v1/login"
    req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
    req.Header.Set("Content-Type", "application/json")
    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        // handle error
    }
    defer resp.Body.Close()
    statuscode := resp.StatusCode
    hea := resp.Header
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Println(string(body))
    fmt.Println(statuscode)
    fmt.Println(hea)
}

补充：golang中发送post的json请求

看代码吧~

package main
import (
    "encoding/json"
    "log"
    "net/http"
)
type test_struct struct {
    Test string
}
//func test(rw http.ResponseWriter, req *http.Request) {
//  req.ParseForm()
//  log.Println(req.Form)
//  //LOG: map[{"test": "that"}:[]]
//  var t test_struct
//  for key, _ := range req.Form {
//      log.Println(key)
//      //LOG: {"test": "that"}
//      err := json.Unmarshal([]byte(key), &t)
//      if err != nil {
//          log.Println(err.Error())
//      }
//  }
//  log.Println(t.Test)
//  //LOG: that
//}
func test(rw http.ResponseWriter, req *http.Request) {
    decoder := json.NewDecoder(req.Body)
    var t test_struct
    err := decoder.Decode(&t)
    if err != nil {
        panic(err)
    }
    log.Println(t.Test)
}
func main() {
    http.HandleFunc("/test", test)
    log.Fatal(http.ListenAndServe(":8082", nil))
}

以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。如有错误或未考虑完全的地方，望不吝赐教。
