后台curl网络请求

<?php

//前端进行网络请求  ajax

//后台进行网络请求用到两种方式  curl   socket

//进行网络请求的步骤

//1.初始化一个curl

//2.对curl进行配置

//3.执行curl

//4.关闭curl

function httpGet($url){

//初始化

$curl = curl_init();

//curl_setopt设置一个cURL传输选项  三个参数

//由curl_init()返回的cURL句柄

//需要设置的CURLOPT_XXX选项

//将设置在option选项上的值

//配置

curl_setopt($curl,CURLOPT_URL,$url);

//作用:1.不让curl_exec自动执行  2.将结果返回一个字符串

curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);

//执行cURL

$res = curl_exec($curl);

//关闭

curl_close($curl);

return $res;

}

// $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wxb2671dd2665ac3a9&secret=afeeba74b070dd6daf6784fe40b2451e";

// $res = httpGet($url);

// echo $res;

//封装post

function httpPost($url,$data){

//初始化一个curl回话

$curl = curl_init();

//声明post请求

curl_setopt($curl,CURLOPT_POST,true);

//设置curl回话

curl_setopt($curl,CURLOPT_URL,$url);

//设置请求体

curl_setopt($curl,CURLOPT_POSTFIELDS,$data);

//设置CURLOPT_RETURNTRANSFER   防止curl_exec直接输出

curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);

//执行

$res = curl_exec($curl);

//关闭

curl_close($curl);

//返回值

return $res;

}
