PHP 利用 curl 发送 post get请求

php-get-post-v1.php

<?php

// 简化版 get、post

// 利用PHP的curl模拟GET功能
function geturl($url)
{

    curl_setopt($ch, CURLOPT_URL, $url); //指定请求链接
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //返回原生输出
    // curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1"); //代理服务器地址
    // curl_setopt($ch, CURLOPT_PROXYPORT, "7890"); //代理服务器端口
    $output = curl_exec($ch); //执行curl
    curl_close($ch); //关闭curl
    return $output; //返回接收的数据
}

// 利用PHP的curl模拟POST功能
function req_post($url, $data) {
    $ch = curl_init(); //初始化curl
    curl_setopt($ch, CURLOPT_URL, $url); //指定请求的URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //设置返回原生输出

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //要POST的数据
    $res = curl_exec($ch); //执行curl
    curl_close($ch); //关闭curl
    return $res; //返回接收的信息
