Question

<?php
include('../simple_html_dom.php');

$fname = "http://www.myurl.com";

$html = file_get_html($fname);

$divs = $html->find('h6');
foreach($divs as $element)
{
 $title = $element->find('a', 0)->plaintext;
 echo $title.'<br>';
}
echo '<br>';
?>

我收到了这个错误：

“无法打开流：HTTP请求失败！HTTP / 1.1 500内部服务器错误.......”

我的网址很长，实际长度为750个字符。如果我使用wget它显示“文件名太长”

我该如何解决？我需要它来使用简单的dom

Answer 1

URL长度可以使用750个字符。最常用的实际限制是2000个字符，这是旧IE中的限制。

您应该尝试模拟发出请求的Web浏览器。请参阅this other question。

编辑：将CURL与您的代码一起使用

<?php

// include is not a function, don't use parens (also use require instead)
require '../simple_html_dom.php';

$fname = "http://www.myurl.com";

$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// don't want to polute your output
//curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL, $fname);
$result=curl_exec($ch);

$html = new simple_html_dom();
$html->load($result);

$divs = $html->find('h6');
foreach($divs as $element)
{
 $title = $element->find('a', 0)->plaintext;
 echo $title.'<br>';
}
echo '<br>';

Answer 2

网址长度很好。该链接可能已损坏或已过期。我尝试使用下面显示的链接，结果似乎很好：

<?php
include("simple_html_dom.php");

$fname = "http://www.youtubeonfire.com/?genre=0&language=0&next_token=rO0ABXNyACdjb20uYW1hem9uLnNkcy5RdWVyeVByb2Nlc3Nvci5Nb3JlVG9rZW7racXLnINNqwMA%0AC0kAFGluaXRpYWxDb25qdW5jdEluZGV4WgAOaXNQYWdlQm91bmRhcnlKAAxsYXN0RW50aXR5SURa%0AAApscnFFbmFibGVkSQAPcXVlcnlDb21wbGV4aXR5SgATcXVlcnlTdHJpbmdDaGVja3N1bUkACnVu%0AaW9uSW5kZXhaAA11c2VRdWVyeUluZGV4TAANY29uc2lzdGVudExTTnQAEkxqYXZhL2xhbmcvU3Ry%0AaW5nO0wAEmxhc3RBdHRyaWJ1dGVWYWx1ZXEAfgABTAAJc29ydE9yZGVydAAvTGNvbS9hbWF6b24v%0Ac2RzL1F1ZXJ5UHJvY2Vzc29yL1F1ZXJ5JFNvcnRPcmRlcjt4cAAAAAEAAAAAAAABds0AAAAAAQAA%0AAAC71ED7AAAAAAFwdAAQMDAwMDAwMDAwMDAwMjAxM35yAC1jb20uYW1hem9uLnNkcy5RdWVyeVBy%0Ab2Nlc3Nvci5RdWVyeSRTb3J0T3JkZXIAAAAAAAAAABIAAHhyAA5qYXZhLmxhbmcuRW51bQAAAAAA%0AAAAAEgAAeHB0AApERVNDRU5ESU5HeA%3D%3D&sort=2";

$html = file_get_html($fname);

$divs = $html->find("h6");
foreach($divs as $element) {
    $title = $element->find("a", 0)->plaintext;
    echo($title . "<br />");
}
echo("<br />");

所以，用URL解决问题，一切都会正常工作！

Answer 3

您说您的网址在您的浏览器中正常运行，而我们这里的所有人都收到了500错误，就像您的脚本一样。

该站点可能会根据IP以及可能的请求的其他标头检查URL中的令牌。因此，您需要找到一种从PHP脚本中获取标记化URL的方法。

为此，您需要先从PHP脚本下载主页，然后找到下一个链接的URL并在脚本中使用此页面。
