如何为https网站选择CURL代理？

I'm trying to connect to a website using CURL on localhost, I tried many proxies but most of them didn't work.

Here is the code:

$url= 'https://stubhub.com';
$curl = curl_init();
curl_setopt( $curl, CURLOPT_URL, $url );
curl_setopt($curl, CURLOPT_REFERER, $url);
curl_setopt( $curl, CURLOPT_AUTOREFERER, TRUE );
curl_setopt( $curl, CURLOPT_HEADER, FALSE );
curl_setopt( $curl, CURLOPT_CONNECTTIMEOUT, 0 );
curl_setopt( $curl, CURLOPT_TIMEOUT, 0 );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE );
curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE );
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);

//certificate
$cacert='C:/xampp/cacert.pem';
curl_setopt( $curl, CURLOPT_CAINFO, $cacert );

//SSL
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

//Cookies
curl_setopt($curl, CURLOPT_COOKIEFILE,__DIR__."/cookie.txt");

//User-Agent
curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36' );

//Proxy
$proxy = '50.115.194.97:8080';
curl_setopt($curl, CURLOPT_PROXY, $proxy);
curl_setopt($curl, CURLOPT_PROXYPORT, 443);
curl_setopt($curl, CURLOPT_HTTPPROXYTUNNEL, TRUE);


//Errors
curl_setopt($curl, CURLOPT_VERBOSE, TRUE);

$data = curl_exec( $curl );
$info = curl_getinfo( $curl );
$error = curl_error( $curl );
curl_close( $curl );

$allInfo = array($data, Info, $error);
echo '<pre>';
print_r($allInfo);
echo '</pre>';

I get the following response:

I tried with proxies that supports https, cookies and those with 443 port.

Is there is an API/library for this purpose?

You can use any of open proxy apis.

For example: gimmeproxy.com/api/getProxy?post=true&supportsHttps=true&maxCheckPeriod=7200&protocol=http

It looks like the proxy you are trying to use is down (not working).

As for me, I built the proxy parser and agregator for our projects. It is getting proxies from a bunch of open proxy lists, saves them to the database and checks them in the loop. It became a very useful tool for us.
