用PHP cURL登录到远程站点

Question

我刚刚使用cURL和它很难找到它的好资源。 我想要做的是登录到远程站点，通过卷曲做登录表单，然后发回它是成功的。

我的代码似乎并不工作，只试图显示该网站的主页。

$username="mylogin@gmail.com"; 
$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); 

我在做什么错。这是工作后，我想重定向到另一个页面，并从我的网站获取内容。

我已经让它变好了一段时间，但稍后重新访问它。由于这个问题被定期查看。这最终是我最终使用的为我工作的。

//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);

查看登录页面的来源。寻找formHTML标记。在该标签内的内容看起来像action=将该值用作$url，而不是表单本身的URL。

此外，当你在那里，验证输入框被命名为你有他们列出。

例如，一个基本的登录表单将类似于：使用

<form method='post' action='postlogin.php'> 
    Email Address: <input type='text' name='email'> 
    Password: <input type='password' name='password'> 
</form> 

上述形式为例，更改到$url值：

$url="http://www.myremotesite.com/postlogin.php"; 

确保你使用的值列在$postdata：

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

它应该只是fin即

我有同样的问题，我发现这个答案on this website。

而且我改变它只是一点点（在最后一行curl_close）

$username = 'myuser'; 
$password = 'mypass'; 
$loginUrl = 'http://www.example.com/login/'; 

//init curl 
$ch = curl_init(); 

//Set the URL to work with 
curl_setopt($ch, CURLOPT_URL, $loginUrl); 

// ENABLE HTTP POST 
curl_setopt($ch, CURLOPT_POST, 1); 

//Set the post parameters 
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password); 

//Handle cookies for the login 
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); 

//Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL 
//not to print out the results of its query. 
//Instead, it will return the results as a string return value 
//from curl_exec() instead of the usual true/false. 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

//execute the request (the login) 
$store = curl_exec($ch); 

//the login is now done and you can continue to get the 
//protected content. 

//set the URL to the protected file 
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/protected/download.zip'); 

//execute the request 
$content = curl_exec($ch); 

curl_close($ch); 

//save the data to disk 
file_put_contents('~/download.zip', $content); 

我认为这是你是对的看for.Am我？

这是我如何ImpressPages解决了这个：

//initial request with login data 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php'); 
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36'); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_COOKIESESSION, true); 
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name'); //could be empty, but cause problems on some hosts 
curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp'); //could be empty, but cause problems on some hosts 
$answer = curl_exec($ch); 
if (curl_error($ch)) { 
    echo curl_error($ch); 
} 

//another request preserving the session 

curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile'); 
curl_setopt($ch, CURLOPT_POST, false); 
curl_setopt($ch, CURLOPT_POSTFIELDS, ""); 
$answer = curl_exec($ch); 
if (curl_error($ch)) { 
    echo curl_error($ch); 
}

巴拿马杰克例不适合我的工作 - 给致命错误：调用未定义功能build_unique_path（）。我用这个代码 - （更简单 - 我的意见）：

// options
$login_email = 'alabala@gmail.com';
$login_pass = 'alabala4807';
$cookie_file_path = "/tmp/cookies.txt";
$LOGINURL = "http://alabala.com/index.php?route=account/login"; 
$agent = "Nokia-Communicator-WWW-Browser/2.0 (Geos 3.0 Nokia-9000i)";

// begin script
$ch = curl_init();

// extra headers
$headers[] = "Accept: */*";
$headers[] = "Connection: Keep-Alive";

// basic curl options for all requests
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
  curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 

// set first URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL);

// execute session to get cookies and required form inputs
$content = curl_exec($ch); 

// grab the hidden inputs from the form required to login
$fields = getFormFields($content);
$fields['email'] = $login_email;
$fields['password'] = $login_pass;

// set postfields using what we extracted from the form
$POSTFIELDS = http_build_query($fields); 
// change URL to login URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL); 

// set post options
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS); 

// perform login
$result = curl_exec($ch); 

print $result; 

function getFormFields($data)
{
 if (preg_match('/()/is', $data, $matches)) {
  $inputs = getInputs($matches[1]);

  return $inputs;
 } else {
  die('didnt find login form');
  }
}

function getInputs($form)
{
 $inputs = array();
 $elements = preg_match_all("/(]+>)/is", $form, $matches);
 if ($elements > 0) {
  for($i = 0;$i   $el = preg_replace('/\s{2,}/', ' ', $matches[1][$i]);
   if (preg_match('/name=(?:["\'])?([^"\'\s]*)/i', $el, $name)) {
    $name = $name[1];

    $value = '';
    if (preg_match('/value=(?:["\'])?([^"\'\s]*)/i', $el, $value)) {
     $value = $value[1];
    }

    $inputs[$name] = $value;
   }
  }
 }

 return $inputs;
}

$grab_url='http://grab.url/alabala';

//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, $grab_url);
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
curl_close($ch);

var_dump($html); 
die;
