cURL在服务器上没有返回任何内容。一切都适用于localhost,但是当它在远程托管中时,getSearchResults()不返回任何内容(或302标头)。这是服务器配置有问题(试过2个不同)。可以用CURLOPT_FOLLOWLOCATION吗?在localhost上尝试true和false - 仍然有效。在远程托管上,由于某种原因,它不允许关注位置,但如果没有在本地工作,我认为不重要。
<?php
class cURL
{
private $username;
private $password;
private static $tmpfname;
public function __construct($username,$password) {
$this->username = $username;
$this->password = $password;
$this->makeCookies($username, $password);
}
private function makeCookies($username, $password) {
self::$tmpfname = tempnam("/tmp", "Cookie");
$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_COOKIEFILE, self::$tmpfname);
curl_setopt($ch, CURLOPT_COOKIEJAR, self::$tmpfname);
curl_setopt($ch, CURLOPT_URL,"http://vk.com/login.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "email={$username}&pass={$password}");
ob_start();
curl_exec($ch);
ob_end_clean();
curl_close($ch);
unset($ch);
}
private function getHTML($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";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_COOKIEFILE, self::$tmpfname);
curl_setopt($ch, CURLOPT_COOKIEJAR, self::$tmpfname);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
$contents = curl_exec($ch);
curl_close($ch);
return $contents;
}
public function getSearchResults($songname) {
$songname = urlencode($songname);
$contents = $this->getHTML("http://vk.com/search?c[section]=audio&c[q]={$songname}");
return $contents;
}
}
?>

302代码是重定向,因此您需要能够使用CURLOPT_FOLLOWLOCATION
从中获取有用的内容。

对于在安全模式下运行php的Web服务器,Web上有很多重定向机制的实现。例如,here(实际上你应该首先查看它)是我有一天为自己的脚本修改的那个。它可以处理多个重定向,并以您可以轻松理解和修改它的方式编写。
