Answer 2

<?php
$url = $url  //调用接口的平台服务地址
$post_string = array('account'=>'admin','password'=>'admin');
$ch = curl_init();
/*$this_header = array(
"content-type: application/x-www-form-urlencoded; 
charset=UTF-8"
);*/
$cookieFile ='cookie.tmp';
//curl_setopt($ch,CURLOPT_HTTPHEADER,$this_header);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile); //同时发送Cookie
curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFile); // 把返回来的cookie信息保存在文件中
curl_setopt($ch,CURLOPT_POST, true); // 加這句
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_string));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$result = curl_exec($ch);
echo var_dump($result);
?>
