PHP readfile() URL问题

Question

我有一个这样的url：

http://r16---sn-4g57kn6e.googlevideo.com/videoplayback?&quality=medium&signature=797C0FEB1961E6226294D5FC19BC0CD28657975C.1E745D852200D14B706F0EBF9EA8762680374564&itag=43&mv=m&ip=84.19.165.220&ipbits=0&ms=au&ratebypass=yes&source=youtube&mt=1390347607&id=8b92b07ff9cd9862&key=yt5&fexp=942502,916626,929305,936112,924616,936910,936913,907231,921090&upn=cMPazwtmyZU&sver=3&sparams=id,ip,ipbits,itag,ratebypass,source,upn,expire&expire=1390371882&type=video%2Fwebm%3B+codecs%3D%22vp8.0%2C+vorbis%22&fallback_host=tc.v12.cache5.googlevideo.com&title=Requiem+For+A+Dream+Original+Song&title=Requiem For A Dream Original Song

问题是readfile()函数会产生特殊字符(错误请求)的错误原因。

如果我使用urlencode()，它会进一步破坏url。

我该怎么处理呢？

Answer 1

您只需在查询字符串中使用urlencode()数据即可。在你的帖子中，你没有逃脱最后一个变量。请勿urlencode()整个URL。这是不恰当的。

我只会使用http_build_query()。

echo 'http://r16---sn-etc' . http_build_query(array(
    'ip' => 84.19.165.220,
    'ipbits' => 0,
    // etc.
    'title' => 'Requiem for a Dream'
));

Answer 2

结合我在原始答案中的内容，再加上Brad的答案中的一些想法，我提供了以下解决方案

<?php
$url='http://r16---sn-4g57kn6e.googlevideo.com/videoplayback?&quality=medium&signature=797C0FEB1961E6226294D5FC19BC0CD28657975C.1E745D852200D14B706F0EBF9EA8762680374564&itag=43&mv=m&ip=84.19.165.220&ipbits=0&ms=au&ratebypass=yes&source=youtube&mt=1390347607&id=8b92b07ff9cd9862&key=yt5&fexp=942502,916626,929305,936112,924616,936910,936913,907231,921090&upn=cMPazwtmyZU&sver=3&sparams=id,ip,ipbits,itag,ratebypass,source,upn,expire&expire=1390371882&type=video%2Fwebm%3B+codecs%3D%22vp8.0%2C+vorbis%22&fallback_host=tc.v12.cache5.googlevideo.com&title=Requiem+For+A+Dream+Original+Song&title=Requiem For A Dream Original Song';
$cleanUrl = parseQuery($url);
$data = getData($cleanUrl);
echo "file read in OK\n";

function parseQuery($url) {
  preg_match('/(https?:\/\/[^?]+\?)(.*)$/', $url, $rawQuery);
  preg_match_all('/([^=]+)=([^&]+)&/', $rawQuery[2], $queries);
  $qArray = array_combine($queries[1], $queries[2]);
  $newUrl = $rawQuery[1] . http_build_query($qArray);
  return $newUrl;
}

function getData($url) {
$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_USERAGENT, $useragent);
$data = curl_exec($curl);
curl_close($curl);
return $data;
}
?>

这主要涉及以下几个步骤：

1. 获取初始网址，并将其拆分为“?之前的东西”和“
2. 之前的东西”未动；stuff after“被分成两个数组--键和查询的值("everything to &")
3. These”和"everything up to readfile()).

“)。然后，使用(根据Brad的回答)=之前的所有数组组合成一个有效的查询字符串。我使用http_build_query curl来获取文件(只是因为我比just更了解它

它似乎对我很有效。如果对你不起作用，请告诉我。
