php cURL函数301错误

Question

我正在使用此代码:

function getUrl($url) {
if(@function_exists('curl_init')) {
    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; CrawlBot/1.0.0)');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT , 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_ENCODING, "");
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    # required for https urls
    curl_setopt($ch, CURLOPT_MAXREDIRS, 15);            
    $site = curl_exec($ch);
    curl_close($ch);
    } else {
    global $site;
    $site = file_get_contents($url);
}
return $site;
};

但我看到错误301永久移动.

我该怎么做才能解决这个问题？你能给我正确的代码吗？

Answer 1

CURLOPT_FOLLOWLOCATION在设置safe_mode或 open_basedir设置时无法激活

你可以试试这个:

解决方案1:

设置safe_mode = Off在您的php.ini文件中(通常在/etc/服务器上).如果这是已经关闭,然后到处寻找open_basedir的东西中的php.ini文件和注释该行(#open_basedir ...).重启apache服务器.

解决方案2:
如果上述方法不起作用(它应该!)试试这个:

<?php
function geturl($url){

(function_exists('curl_init')) ? '' : die('cURL Must be installed for geturl function to work. Ask your host to enable it or uncomment extension=php_curl.dll in php.ini');

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; CrawlBot/1.0.0)');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT , 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    //curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_ENCODING, "");
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    # required for https urls
    curl_setopt($ch, CURLOPT_MAXREDIRS, 15);     

$html = curl_exec($curl);
$status = curl_getinfo($curl);
curl_close($curl);

if($status['http_code']!=200){
    if($status['http_code'] == 301 || $status['http_code'] == 302) {
        list($header) = explode("\r\n\r\n", $html, 2);
        $matches = array();
        preg_match("/(Location:|URI:)[^(\n)]*/", $header, $matches);
        $url = trim(str_replace($matches[1],"",$matches[0]));
        $url_parsed = parse_url($url);
        return (isset($url_parsed))? geturl($url):'';
    }
}
return $html;
}

?>

Answer 2

您可能需要使用location header标志启用以下重定向:

curl -L <URL>
