优雅的封装CURL请求

<?php
/**
 * PHP发送请求
 * @param string $api       接口地址
 * @param array  $postData  POST请求数据
 */
function httpRequest($api, $postData = array())
{
    //1.初始化
    $ch = curl_init();
    //2.配置
        //2.1设置请求地址
        curl_setopt($ch, CURLOPT_URL, $api);
        //2.2数据流不直接输出
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        //2.3POST请求
        if ($postData) {
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
        }
        //curl注意事项，如果发送的请求是https，必须要禁止服务器端校检SSL证书
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    //3.发送请求
    $data = curl_exec($ch);
    //4.释放资源
    curl_close($ch);
    return json_decode($data, true);
}
