如何用post的方式跨域调用接口
使用jsonp接口的方式输出数据，也可以在服务器端加上允许域名来源设置，代码如下：
<?php $origin = isset($_SERVER['HTTP_ORIGIN'])? $_SERVER['HTTP_ORIGIN'] : ''; $allow_origin = array( '//m.sbmmt.com', '//m.sbmmt.com', 'http://m.php.cn', ); if(in_array($origin, $allow_origin)){ header('Access-Control-Allow-Origin:'.$origin); }
function https_request($url,$data = null){ $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; }
