如何重用php curl响应cookie并绕过脚本后续执行的登录步骤?

I have the following php code that logs in to a password protected page and grabs the protected page.The script is working fine but i want to use the login function only once, if i want to grab another protected page within same domain .

我有以下php代码登录到密码保护页面并获取受保护页面。脚本运行良好，但是如果我想在相同的域中获取另一个受保护的页面，我只希望使用登录函数一次。

i want to use cookie file to open the next protected page instead of using login function again !in another word i just want to bypass the login step for grabbing other protected pages.

我想使用cookie文件来打开下一个受保护的页面，而不是再次使用登录功能!换句话说，我只是想绕过登录步骤，来抓取其他受保护的页面。

Could any one show me how this can be done?

谁能告诉我这是怎么做的吗?

Note: My login function doesnt create any cookies i dont see it in same folder as the script!could any one tell me why?

注意:我的登录功能没有创建任何cookie，我没有看到它在同一文件夹与脚本!谁能告诉我为什么吗?

        $ch=login();
    $html=downloadUrl('http://www.example.com/page1.asp', $ch);

    ////echo $html;


    function downloadUrl($Url, $ch){
        curl_setopt($ch, CURLOPT_URL, $Url);
        curl_setopt($ch, CURLOPT_POST, 0);

2 个解决方案

#1

Use

使用

curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFileLocation);
curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFileLocation);

In second request where $cookieFileLocation is the location of your cookie file.

在第二个请求中，$cookieFileLocation是您的cookie文件的位置。

You have to have 2 requests. First is login request which fills the cookie file.

你必须有两个请求。首先是填充cookie文件的登录请求。

You have to check if your cookie file exists is_file($cookieFileLocation), and if it does you can perform second request for download protected content bypassing the login process.

您必须检查您的cookie文件是否存在is_file($cookieFileLocation)，如果存在，您可以对下载受保护的内容执行第二个请求，绕过登录过程。

You should note that most of the systems has session expire time, so you have to make login after period of time. I would check html of returned page for login error as mark that i have to login again.

您应该注意到，大多数系统都有会话过期时间，因此必须在一段时间后登录。我会检查返回页面的html，检查是否有登录错误，标记我必须再次登录。

#2

You need to login first time and then reference cookie file path in subsequent request.

您需要第一次登录，然后在后续请求中引用cookie文件路径。

function curlPost($url,$postData){
    $ch= curl_init();
    curl_setopt_array($ch, array(
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => $postData,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_CONNECTTIMEOUT=>30,
        CURLOPT_SSL_VERIFYPEER=>false,
        CURLOPT_USERAGENT=>"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)",
        CURLOPT_COOKIESESSION => true,
        CURLOPT_COOKIEFILE => 'cookie.txt',
        CURLOPT_COOKIEJAR => 'cookie.txt'
    ));
    $output = curl_exec($ch);
    curl_close( $ch );
    return $output; 
}

$postData = array(
    'email' => 'aryan022@gmail.com',
    'password' => 'aryan022',
    'redirect_to' => 'http://localhost/cakephp/account '
 );

 $output=curlPost("http://localhost/cakephp/login",$postData);

  /*use for subsequest request without passing all postData once login
  $postData = array();
  $output=curlPost("http://localhost/cakephp/account",$postData);
 */
 echo $output;

Use

使用

curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFileLocation);
curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFileLocation);
