Question

我正在尝试获取观众人数，因此我可以检查是否在https://www.dlive.tv/上有流媒体在线。如果您在流媒体页面（https://www.dlive.tv/thelongestchain）上查看页面源，则有很多json，其中有“ watchingCount”。

基本上，如果他们的观看者人数为1或更多，我希望让该流媒体出现在我网站的“实时直播”部分中，但是无论如何我都无法弄清楚如何获得观看者人数。我知道如果我使用python并可以从PC运行它，则可以使用Selenium之类的东西，但是我需要该站点才能知道它。

DLive尚无api，因此我不知道如何拨打电话（或请求我不知道其术语）来获取此信息。当我在chrome上的网络标签中查看时，发现有一个呼叫（https://graphigo.prd.dlive.tv/）提供了我认为的流信息。我还需要我的authkey吗？

我意识到这个问题遍及整个领域，但这是因为我和我也试图在最近几天解决这个问题。如果我将viewercount作为变量，那么我将知道如何在网站的“ Live Now”部分中显示流媒体，而我只是不知道如何获取必要的数据。

如果除了获取观众数外，还有另一种方法可以检查流媒体是在线还是离线，那么这也可以。如果有人可以帮助我，我将非常感谢。

我尝试抓取页面，但我认为您不能抓取动态内容。当我尝试使用SimpleHTMLDom时，它只是返回静态元素。

<?php
require 'simple_html_dom.php';

$html = file_get_html('https://www.dlive.tv/thelongestchain')

if(($html->find('video', 0))) { 
    echo 'online';
}else{
    echo 'offline';
}

/* The video element is only on the page if the streamer is live, but it doesn't return because it's not static I presume */

?>

我根本不知道如何进行调用/请求以获取供观看者计数的json数据，或者如何获取任何其他可以检查流媒体是否在线的数据。我所做的所有抓取操作均未返回任何非静态的元素（无论拖缆是联机还是脱机都相同）。

尝试使用cURL，就像魔杖一样。

这将返回整个页面，我想包括您要查找的JSON：

<?php

        $curl = curl_init('https://www.dlive.tv/thelongestchain'); 
        curl_setopt($curl, CURLOPT_FAILONERROR, true); 
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); 
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);   
        $result = curl_exec($curl);
        var_dump($result); // you do as you need to here
        curl_close($curl);   

?>

这里是<script>，其中包含我认为您需要的数据。假设您正在寻找“ watchingCount”吗？

我认为您只需要陷入一个循环，使URL动态化，就可以浏览正在通过网站监视的所有流光。
