Question

我是新手使用cURL ....每当我运行这个时，我会得到一个页面，上面写着＆＃34;在这台服务器上找不到请求的URL / files /。＆＃34;但是，如果我转到浏览器上的链接，它就会显示出来。请协助。我看过类似的问题，但找不到解决问题的方法。

<?php
$username="user"; 
$password="pass"; 
$url="http://website.com/login/"; 
$cookie="cookie.txt"; 

$postdata = "login=$username&pass=$password";


//set the directory for the cookie using defined document root var
$dir = DOC_ROOT;

//the info per user with custom func. 
$path = $dir;

//login form action url 

$cookie_file_path = $path."/cookie.txt";

$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_exec($ch);

//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, "http://website.com/files/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
echo $html;
curl_close($ch);

?>

Answer 1

$postdata = array(
  'login' => $username,
  'pass' => $password
);

curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

Answer 2

更改

curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);

以

curl_setopt($ch, CURLOPT_COOKIE, $cookie); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);

确保您在当前目录上写入权限，以便curl可以创建Cookie文件cookie.txt

你最终会得到类似的东西：

<?php $username="user"; $password="pass"; $url_login="http://website.com/login/"; $url_files="http://website.com/files/"; $cookie="cookie.txt"; $postdata = "login=$username&pass=$password"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url_login); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie); curl_setopt($ch, CURLOPT_COOKIE, $cookie); curl_setopt($ch, CURLOPT_USERAGENT,"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); curl_exec($ch); curl_setopt($ch, CURLOPT_URL, $url_files); $html = curl_exec($ch); echo $html; curl_close($ch); ?>

注意：

有时，少即是多。

Answer 3

您提供的网址http://website.com/files/具有重定向功能，因此CURL必须启用选项才能跟踪重定向。

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

在您的代码中，您有

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

0表示false，因此您在HTTP 30x上禁用了关注

找不到PHP cURL URL
