php post请求https

<?php
$url = 'https://www.xxx.com';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);//这个是重点。
$data = curl_exec($curl);
curl_close($curl);
var_dump($data);

注意

当请求https的数据时，会要求证书，这时候，加上下面这两个参数，规避ssl的证书检查

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
