 創建Clinet請求POST、GET、PUT、DELETE

常見的網頁請求方法，以下範例

package main

import (

"bytes"

"fmt"

"io"

"net/http"

"strings"

)

func main() {

client_POST("https://blog.oc-city.com")

client_GET("https://blog.oc-city.com")

client_PUT("https://blog.oc-city.com")

client_DELETE("https://blog.oc-city.com")

}

func client_GET(content string) {

//創建GET請求

resp, err := http.Get(content)

if err != nil {

fmt.Print(err, err)

}

close := resp.Body

bytes, err := io.ReadAll(close)

fmt.Println(string(bytes))

}

func client_POST(content string) {

//創建POST請求

url := content

post_ := "account=admin&password=admin" //發送POST數據

        //post_ := "{\"account\":\"admin\",\"password\":\"admin\"}" //發送POST數據

response, err := http.Post(url, "application/x-www-form-urlencoded", bytes.NewBuffer([]byte(post_)))

if err != nil {

fmt.Println("err", err)

}

b, err := io.ReadAll(response.Body)

fmt.Print(string(b))

}

func client_PUT(content string) {

//創建PUT請求

url := content

payload := strings.NewReader("{\"account\":\"admin\",\"password\":\"passwd\"}")

req, _ := http.NewRequest("PUT", url, payload)

req.Header.Add("Content-Type", "application/json")

res, _ := http.DefaultClient.Do(req)

defer res.Body.Close()

body, _ := io.ReadAll(res.Body)

fmt.Println(res)

fmt.Println(string(body))

}

func client_DELETE(content string) {

//創建DELETE請求

url := content

payload := strings.NewReader("{\"delete_id\":1,\"content\",\"留言A\":}")

req, _ := http.NewRequest("DELETE", url, payload)

req.Header.Add("Content-Type", "application/json")

res, _ := http.DefaultClient.Do(req)

defer res.Body.Close()

body, _ := io.ReadAll(res.Body)

fmt.Println(res)

fmt.Println(string(body))

}
