[英]PHP - Using cURL to get a cookie from a redirecting URL but getting no response
我有一个cURL命令,通过它我可以对网站进行身份验证,它会给出一个cookie作为响应,然后使用该cookie,我可以对该服务进行REST API调用
这是有效的cURL命令:
curl -v -l -H "Content-Type: application/x-www-form-urlencoded" -H "Referrer:https://mywebsiteurl.com?ticket=unique_ticket_id" -d "_charset_=UTF-8&errorMessage=User+name+and+password+do+not+match&resource=%2F&username=username%40domain.com&password=XXXXXX&nextpage=welcomeCM.jsp&viewInfo=&ticket=unique_ticket_id" -X POST https://mywebsiteurl.com/index.jsp
在上面的命令中,票证参数包含唯一的票证ID,该ID与网站网址一起传递
现在,我正在尝试使用cURL PHP实现相同的功能,这是PHP代码:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://mywebsiteurl.com/index.jsp");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "_charset_=UTF-8&errorMessage=User+name+and+password+do+not+match&resource=%2F&username=username%40domain.com&password=XXXXXX&nextpage=welcomeCM.jsp&viewInfo=&ticket=unique_ticket_id");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array(
'Content-Type: application/x-www-form-urlencoded',
'Referrer: https://mywebsiteurl.com?ticket=unique_ticket_id'
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
echo $result;
curl_close ($ch);
这里echo $result
什么也没显示
然后我尝试了var_dump($result);
它给出以下输出: string(0) ""
,这意味着$response
没有返回任何内容
之后,我尝试了curl_getinfo
并添加了以下代码:
echo "<pre>";
$info = curl_getinfo($ch);
print_r($info);
echo "</pre>";
这给了我以下数组:
Array
(
[url] => https://mywebsiteurl.com/index.jsp
[content_type] => text/html;charset=UTF-8
[http_code] => 302
[header_size] => 1306
[request_size] => 619
[filetime] => -1
[ssl_verify_result] => 0
[redirect_count] => 0
[total_time] => 1.540687
[namelookup_time] => 0.028262
[connect_time] => 0.171774
[pretransfer_time] => 0.462507
[size_upload] => 280
[size_download] => 0
[speed_download] => 0
[speed_upload] => 181
[download_content_length] => 0
[upload_content_length] => 280
[starttransfer_time] => 1.54066
[redirect_time] => 0
[redirect_url] => https://mywebsiteurl.com/welcomeCM.jsp?username=username@domain.com&locale=en_US
[primary_ip] => YY.YYY.YYY.YY
[certinfo] => Array
(
)
[primary_port] => 443
[local_ip] => XX.XX.XXX.XX
[local_port] => 47692
)
现在我的目标是将cookie放入$result
,但是它是空的,什么也没有返回
是否在cURL命令等效的PHP代码中缺少某些内容?
有人可以帮我吗,并指出我要检索Cookie的方向
非常感谢!
UPDATE
我添加了curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
成功登录后使其遵循302重定向的请求
但是这一次执行cURL之后, echo $result
将我当前的本地网页重定向到/Dashboard?viewInfo=
,这显然不存在
也是这次var_dump($result);
结果为: string(1462) " "
而curl_getinfo($ch)
提供了以下数组:
Array
(
[url] => https://mywebsiteurl.com/welcomeCM.jsp?username=username@domain.com&locale=en_US
[content_type] => text/html;charset=UTF-8
[http_code] => 200
[header_size] => 1821
[request_size] => 956
[filetime] => -1
[ssl_verify_result] => 0
[redirect_count] => 1
[total_time] => 1.746911
[namelookup_time] => 1.5E-5
[connect_time] => 1.5E-5
[pretransfer_time] => 6.2E-5
[size_upload] => 0
[size_download] => 1462
[speed_download] => 836
[speed_upload] => 0
[download_content_length] => 1462
[upload_content_length] => 0
[starttransfer_time] => 0.146587
[redirect_time] => 1.6003
[redirect_url] =>
[primary_ip] => YY.YYY.YYY.YY
[certinfo] => Array
(
)
[primary_port] => 443
[local_ip] => YY.YY.YYY.YY
[local_port] => 47705
)
仍然无法在此处获取所需的Cookie,请帮助!
如果要使用给定的卷发功能,则可以尝试使用CURLOPT_COOKIEJAR / CURLOPT_COOKIEFILE来存储和获取Cookie。 这是基于文件的。 在这种情况下,curl将在文件中写入与Cookie相关的所有信息。
您可以定义此文件的位置。
通过使用CURLOPT_COOKIEJAR,您将告诉curl它将捕获cookie数据。
// create cookie file
$cookie = __DIR__ . "/where/you/want/to/store/your/cookie/mycookie.txt";
fopen($cookie, "w");
// you may want to use some random identicator in your cookie file
// to make sure it does not get overwritten by some action
// prepare login
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://mywebsiteurl.com/index.jsp");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// tell curl to follow redirects
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURlOPT_POSTFIELDS, "username=usernam&password=XXXXXX");
curl_setopt($ch, CURLOPT_POST, 1);
// set a jar, to store your cookie
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
$headers = array(
'Content-Type: application/x-www-form-urlencoded',
'Referrer: https://mywebsiteurl.com?ticket=unique_ticket_id'
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// do login
$loginResult = curl_exec($ch);
// check if your login has worked according to the given result by any method you want
if (preg_match("/Welcome/", $loginResult)) {
// simple regex for demonstration purpose
}
// now you could load your cookie out of the file, or just use the file for future requests
如果登录成功,则所有信息都将存储在cookie文件中。
现在,您可以将cookie再次与curlopt CURLOPT_COOKIEFILE一起使用,以备将来使用。
// do other request, with your cookie
curl_setopt($ch, CURLOPT_URL, "https://mywebsiteurl.com/api/rest.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "your new post data");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
// set a jar to update your cookie if needed
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
// give curl the location of your cookie file, so it can send it
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
