HTTPS上的套接字错误，但HTTP PHP上没有

Question

   if (strstr($_SERVER['PHP_SELF'], "/")) { 
        $location = array(); 
        $location = explode("/", $_SERVER['PHP_SELF']); 
        $folder = $location[count($location) - 2]; 
    } 
    else { 
        $folder = $_SERVER['PHP_SELF']; 
    }

    //script, runs in background
    $host = HOST;
    $remote_house = 'https://'.$host.'/'.$folder.'/controllers/background';

    $socketcon = fsockopen($host, 80);

    if($socketcon) {   
        $socketdata = "GET $remote_house/".$scriptName." HTTPS 1.1\r\nHost: $host\r\nConnection: Close\r\n\r\n"; 
        fwrite($socketcon, $socketdata); 
        fclose($socketcon);
    }

Answer 1

$socketdata = "GET $remote_house/".$scriptName." HTTPS 1.1\r\n...

这是一个无效的HTTP和一个无效的HTTPS请求。首先，它应该是HTTP/1.1而不是HTTPS1.1。对于HTTPS，您需要首先创建到对等体的SSL/TLS连接，然后通过该连接发送HTTP请求。

$remote_house = 'https://'.$host.'/'.$folder.'/controllers/background';

此外，请求中的path组件不应包含完整的URL，而应仅包含路径，即'/'.$folder.'/controllers/background'。

$socketcon = fsockopen($host, 80);

对于HTTPS，您需要连接到端口443，而不是80，然后在发送HTTP请求之前在那里进行SSL/TLS握手。
