使用Curl和PHP保持会话活跃

标签: php session curl

我正在尝试连接到API,对用户进行身份验证,然后查看用户详细信息。这是通过首先访问

的登录端点来完成的
http://api.example.com/login/<username>/<password>

登录,然后查看以下内容以查看用户详细信息:

http://api.example.com/user/

这一切都可以在网络浏览器中使用。但是,一旦我尝试使用Curl,登录工作正常,但在尝试查看用户详细信息时,我会收到401,未经授权的错误。我相信这是因为Curl没有正确保存会话cookie?有人可以指出它为什么不工作以及如何解决它?我已经尝试过搜索堆栈交换,但是,我尝试过的解决方案都没有适用于我的情况。我用来卷曲端点的代码如下所示。谢谢!

define("COOKIE_FILE", "cookie.txt");

// Login the user
$ch = curl_init('http://api.example.com/login/joe/smith');
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
echo curl_exec ($ch);

// Read the session saved in the cookie file
echo "<br/><br/>";
$file = fopen("cookie.txt", 'r');
echo fread($file, 100000000);   
echo "<br/><br/>";

// Get the users details
$ch = curl_init('http://api.example.com/user');
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
echo curl_exec ($ch);

此代码将输出:

您还需要设置选项CURLOPT_COOKIEFILE

本手册将其描述为

  

包含cookie数据的文件的名称。 cookie文件可以   是Netscape格式,或只是普通的HTTP风格的标头转储到   文件。如果名称是空字符串,则不会加载cookie,但是   cookie处理仍然启用。

由于您正在使用cookie jar,因此在请求完成时最终会保存cookie,但由于未提供CURLOPT_COOKIEFILE,因此cURL不会在后续请求中发送任何已保存的cookie。

您已正确使用“CURLOPT_COOKIEJAR”(写作),但您还需要设置“CURLOPT_COOKIEFILE”(阅读)

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

答案 2 :(得分:17)

这是您使用会话进行CURL的方式

//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);
}

我在ImpressPages上看过这个

Yup,通常被称为'cookie jar'Google应该提供很多例子:

http://devzone.zend.com/16/php-101-part-10-a-session-in-the-cookie-jar/

http://curl.haxx.se/libcurl/php/examples/cookiejar.html&lt; - 好的例子恕我直言

复制最后一个,这样它就不会消失......

  

登录到一个页面,然后从Mitchell撰写的第一页传递所有Cookie的另一页

<?php
/*
This script is an example of using curl in php to log into on one page and 
then get another page passing all cookies from the first page along with you.
If this script was a bit more advanced it might trick the server into 
thinking its netscape and even pass a fake referer, yo look like it surfed 
from a local page.
*/

$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"http://www.myterminal.com/checkpwd.asp");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "UserID=username&password=passwd");

ob_start();      // prevent any output
curl_exec ($ch); // execute the curl command
ob_end_clean();  // stop preventing output

curl_close ($ch);
unset($ch);

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"http://www.myterminal.com/list.asp");

$buf2 = curl_exec ($ch);

curl_close ($ch);

echo "<PRE>".htmlentities($buf2);
