go 实现发送post请求的两种方法

1、()

package main

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

type JsonPostSample struct {
}

func (this *JsonPostSample) SamplePost() {
	info := make(map[string]string)    
	info["username"] = "******"
	info["password"] = "******"

	bytesData, err := (info)
	if err != nil {
		(())
		return
	}
	(bytesData)

	reader := (bytesData)
	

	url := ""     //要访问的Url地址
	request, err := ("POST", url, reader)
	defer ()    //程序在使用完回复后必须关闭回复的主体
	if err != nil {
		(())
		return
	}
	("Content-Type", "application/json;charset=UTF-8")   
	//必须设定该参数,POST参数才能正常提交，意思是以json串提交数据
	
	client := {}
	resp, err := (request) //Do 方法发送请求，返回 HTTP 回复
	if err != nil {
		("22222", ())
		return
	}

	respBytes, err := ()   
	if err != nil {
		("33333", ())
		return
	}

	//byte数组直接转成string，优化内存
	str := (*string)((&respBytes))
	("44444", *str)

	//(string(respBytes))
}

func main() {
	a := new(JsonPostSample)
	()

}

2、()

package main

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

func main() {
	song := make(map[string]string)
	song["username"] = "******"
	song["password"] = "******"
	bytesData, _ := (song)

	res, err := ("",
		"application/json;charset=utf-8", ([]byte(bytesData)))
	if err != nil {
		("Fatal error ", ())
	}

	defer ()

	content, err := ()
	if err != nil {
		("Fatal error ", ())
	}

	//(string(content))
	str := (*string)((&content)) //转化为string,优化内存
	(*str)
}
