go语言实现post、get请求及设置header、cookie

一、实现代码

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io/ioutil"
	"net/http"
	"unsafe"
)

func Post() {
    
    
	client := &http.Client{
    
    }

	// 设置请求体，json格式
	song := make(map[string]string)
	song["mldm"] = "01"
	bytesData, _ := json.Marshal(song)

	req, err := http.NewRequest("POST", "https://yz.chsi.com.cn/zsml/pages/getZy.jsp",
		bytes.NewBuffer([]byte(bytesData)))
	if err != nil {
    
    
		fmt.Println("Fatal error ", err.Error())
	}

	//设置请求头
	req.Header.Set("content-type", "application/json")
	req.Header.Set("cookie", "123456")
	req.Header.Set("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36")

	resp, err := client.Do(req)
	defer resp.Body.Close()

	content, err := ioutil.ReadAll(resp.Body)
	if err != nil {
    
    
		fmt.Println("Fatal error ", err.Error())
	}

	//fmt.Println(string(content))       // 直接打印
	str := (*string)(unsafe.Pointer(&content)) //转化为string,优化内存
	fmt.Println(*str)

}

func Get() {
    
    
	client := &http.Client{
    
    }

	req, err := http.NewRequest("GET", "https://www.runoob.com/html/html-tutorial.html",
		nil)
	if err != nil {
    
    
		fmt.Println("Fatal error ", err.Error())
	}

	//设置请求头
	req.Header.Set("content-type", "application/json")
	req.Header.Set("cookie", "123456")
	req.Header.Set("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36")

	resp, err := client.Do(req)
	defer resp.Body.Close()
	content, err := ioutil.ReadAll(resp.Body)
	if err != nil {
    
    
		fmt.Println("Fatal error ", err.Error())
	}
	//fmt.Println(string(content))       // 直接打印
	str := (*string)(unsafe.Pointer(&content)) //转化为string,优化内存
	fmt.Println(*str)

}

func main() {
    
    
	Post()
	Get()
}
