使用PHP cURL登录到远程站点 [英] Login to remote site with PHP cURL

问题描述

我刚开始使用cURL，它很难找到好的资源。
我想做的是登录到一个远程站点，通过curl做登录表单，然后发回它是成功的。

I'm new to using cURL and its hard to find good resources for it. What I'm trying to do is login to a remote site, by having curl do the login form and then send back that it was successful.

代码我似乎没有工作，只尝试显示网站的主页。

The code I have doesn't seem to work and only tries to show the main page of the site.

    $username="[e-mail]"; 
$password="mypassword"; 
$url="http://www.myremotesite.com/index.php?page=login"; 
$cookie="cookie.txt"; 

$postdata = "email=".$username."&password=".$password; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result;  
curl_close($ch);

我做错了什么。在这工作后，我想重定向到另一个页面，并从我的网站获取内容。

What am I doing wrong. After this is working I want to redirect to another page and get content from my site.

推荐答案

好，但后来重新审视它。因为这个问题是定期观看的。这最终是我最终使用它为我工作。

I had let this go for a good while but revisited it later. Since this question is viewed regularly. This is eventually what I ended up using that worked for me.

//username and password of account
$username = trim($values["email"]);
$password = trim($values["password"]);

//set the directory for the cookie using defined document root var
$dir = DOC_ROOT."/ctemp";
//build a unique path with every request to store 
//the info per user with custom func. 
$path = build_unique_path($dir);

//login form action url
$url="https://www.site.com/login/action"; 
$postinfo = "email=".$username."&password=".$password;

$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, $postinfo);
curl_exec($ch);

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