关于Buffer* byte[] string bufio简单认识

package main

import (
    // "bufio"
    // "io"
    "bytes"
    "io/ioutil"
    "net/http"
)

func main() {
    var buf = bytes.NewBufferString("{request: {action: \"GET_COMMON_CATEGORIES\",body:{shopId: \"1000001\",deviceId: \"123455\"}}}")
    // buf := bufio.NewReader(s)
    resp, err := http.Post("http://www.xxx.net.cn/shop/client", "text/json;charset=UTF-8", buf)
    if err != nil {
        println(err.Error())
    }
    // println(resp)
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        println(err.Error())
    }
    var buf2 = bytes.NewBuffer(body)
    println(buf2.String())

    //os  file  bufio-> bytes buffer string
}
