curl url(custum port) html grab show blank on live site php - curl url(custum port) html grab show blank on live site php

我想使用自定义端口（而不是 8080）获取 URL 的 html，即 abc.com:1234 但它在实时服务器上显示为空白，但在本地主机上工作正常

我的代码：

     <?php ini_set("display_errors",1); error_reporting(E_ALL);
                        ini_set('allow_url_fopen', true); ini_set('allow_url_include', true); ini_set('allow_url_include', 'on'); ?> 
                    <?php 
 //getSslPage("http://portquiz.net:8080"); 
         getSslPage("http://portquiz.net:666");         
                function getSslPage($url) { 
         $curl_connection =   curl_init($url); 
        //set options ///
        curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 3990);
                        curl_setopt($curl_connection, CURLOPT_USERAGENT,   "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
                        curl_setopt($curl_connection, CURLOPT_HTTPHEADER, array(
                             'Content-Type: text/xml',
                            'Connection: Keep-Alive',
                            'Keep-Alive: 300' ));
                        curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl_connection,CURLOPT_SSL_VERIFYHOST,0); 
    curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1); 
    curl_setopt($curl_connection, CURLOPT_TIMEOUT, 20); //old value 15 
            //set data to be posted 
            //curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); 
            //perform our request  
            $result = curl_exec($curl_connection);  
            echo "<h1 style=color:blue>Output Result:</h1><br>"; 
             echo htmlentities($result);  
             echo "<h1 style=color:blue>|Curl Exec Detail:</h1><br>"; 
             //var_dump($result); 
             echo "<pre>";
             print_r(curl_getinfo($curl_connection));   
            echo "</pre>";  
             echo curl_errno($curl_connection) . '<br/>';
             echo curl_error($curl_connection) . '<br/>';


                        } exit; ?>

请帮助我，我正在从最近 2 天开始工作，但没有成功，谢谢

在您上面发布的示例中，我没有看到curl_exec，所以我添加了它。

这对我有用：

<?php ini_set("display_errors", 1);
error_reporting(E_ALL);
ini_set('allow_url_fopen', true);
ini_set('allow_url_include', true);
ini_set('allow_url_include', 'on');
?>
<?php
//getSslPage("http://portquiz.net:8"); 
function getSslPage($url) {
    $curl_connection = curl_init($url); //set options ///curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 3990);
    curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
    curl_setopt($curl_connection, CURLOPT_HTTPHEADER, array(
        'Content-Type: text/xml',
        'Connection: Keep-Alive',
        'Keep-Alive: 300'));
    curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl_connection, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl_connection, CURLOPT_TIMEOUT, 20); //old value 15 //set data to be posted //curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); //perform our request  $result = curl_exec($curl_connection);  echo "<h1 style=color:blue>Output Result:</h1><br>";  echo htmlentities($result);   echo "<h1 style=color:blue>|Curl Exec Detail:</h1><br>";  //var_dump($result);  echo "<pre>";
    echo "</pre>";
    echo curl_errno($curl_connection) . '<br/>';
    echo curl_error($curl_connection) . '<br/>';
    print_r(curl_exec($curl_connection));
    print_r(curl_getinfo($curl_connection));
}
getSslPage("http://portquiz.net:666");

结果：

代码对我来说似乎很好，作为一种解决方法，请尝试更改：

curl_setopt ( $curl_connection, CURLOPT_RETURNTRANSFER, true );

自

curl_setopt ( $curl_connection, CURLOPT_RETURNTRANSFER, 1 );

如 curl-exec PHP 手册页的返回值部分所述：http://php.net/manual/function.curl-exec.php

您应该为重定向启用CURLOPT_FOLLOWLOCATION选项，但如果您的服务器处于safe_mode和/或open_basedir有效，这将是一个问题，这也可能导致 curl 问题。

这里

的重要信息是：

连接在 20001 毫秒后超时

这意味着您的连接未通过该主机。原因可能是防火墙或网络配置错误在两端 - 您的服务器或远程服务器。

我想到的第一件事是低于 666 的端口号（1024）。在 Unix 系统上，只有特权用户才能侦听这些端口。因此，如果您使用的是普通用户，则可能无法收听。

但是，如果您能够从本地计算机连接到它，则问题可能出在您的服务器上。为了检查它是否配置为将连接传递到任何端口，您可以在终端中尝试以下简单命令：

$ telnet portquiz.net 666
Trying 178.33.250.62...
Connected to portquiz.net.
Escape character is '^]'.
GET /

GET / HTTP 请求，您需要在收到提示时从键盘输入。如果未收到提示，并且在一段时间后收到超时消息 - 则主机配置为不将连接传递到自定义端口。这通常是共享主机的问题。

在这种情况下，您应该执行以下操作之一：

重新配置主机以允许此类连接
使用一些标准端口：80、8080、443 等
将您的托管服务提供商切换到没有此类限制的提供商。

编辑：您也可以从PHP脚本中进行简单的检查：

$fp = fsockopen("portquiz.net", 666);
var_dump($fp);

如果var_dump的结果false或者您执行该页面超时 - 原因是您的主机上不允许连接到随机端口。

请注意，PHP 中的curl_*函数都是 curl 程序的包装器。

这意味着您可以通过命令行尝试同样的事情。

如果您可以通过SSH或Telnet连接实时服务器，

尝试curl http://portquiz.net:666 -v，看看真正的问题是什么。

您是否注意到此错误"连接在 20001 毫秒后超时"

在此处增加连接超时时间，添加足够的时间而不是 20

curl_setopt($curl_connection, CURLOPT_TIMEOUT, 20);
