Question

以下是我正在使用的代码：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->paypal_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: ' . $url_parsed['host']));
$res = curl_exec($ch);
curl_close($ch);

this-＆gt; paypal_url是sandbox api url，url_parsed ['host']是沙盒paypal主机名这些都是正确的，但我遇到的问题是每次调用$ res总是为空。

在从paypal开发者网站获取此代码之前，我使用了以下代码：

$fp = fsockopen('ssl://' . $url_parsed['host'],"443",$err_num,$err_str,30);
fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n"); 
fputs($fp, "Host: $url_parsed[host]\r\n"); 
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); 
fputs($fp, "Content-length: ".strlen($post_string)."\r\n"); 
fputs($fp, "Connection: close\r\n\r\n"); 
fputs($fp, $post_string . "\r\n\r\n");

并且无法打开套接字错误。

在使用ssl之前我使用的是以下代码： $ fp = fsockopen（$ url_parsed ['host']，“80”，$ err_num，$ err_str，30）;

我收到了这个回复：

请帮我找到解决方案。
