ssl - 在 Wordpress 插件中使用 Curl SSL 证书

Question

我有以下代码:

$curl = curl_init();

curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post_fields));
curl_setopt($curl, CURLOPT_VERBOSE, '1');           
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, '0');            
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, '0');            
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSLCERT, 'cert.pem');            
curl_setopt($curl, CURLOPT_SSLKEY,  'cert.pem');
curl_setopt($curl, CURLOPT_SSLKEYPASSWD, 'mypass');
curl_setopt($curl, CURLOPT_URL, 'https://example.com:18443/Handler');

当我只运行这段代码时，一切正常。 (包括 SSL 证书)。

但是，当我在 WP 插件中使用此代码时，出现:curl_error: unable to use client certificate (no key found or wrong pass phrase?)

我认为 Wordpress 核心中有一些隐藏的过滤器，它们会阻止/编辑我的 ssl Curl 请求。

如何避开 WP http curl 过滤器？

我找到了解决方案:

$certfile = plugin_dir_path(__FILE__) . '/cert.pem';

$curl = curl_init();

curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post_fields));
curl_setopt($curl, CURLOPT_VERBOSE, '1');           
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, '0');            
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, '0');            
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSLCERT, $certfile);            
curl_setopt($curl, CURLOPT_SSLKEY,  $certfile);
curl_setopt($curl, CURLOPT_SSLKEYPASSWD, 'mypass');
curl_setopt($curl, CURLOPT_URL, 'https://example.com:18443/Handler');
