Question

我有一个cURL命令用于我对网站进行身份验证，它会给出一个cookie作为响应，然后使用此cookie我可以对此服务进行REST API调用

这是工作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，ticket参数包含与网站URL一起传递的唯一票证ID

现在，我尝试使用cURL PHP完成同样的操作，这里是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);

此处echo $result不显示任何内容

然后我尝试了var_dump($result);并提供了此输出：string(0) ""这意味着$response

中没有返回任何内容

在此之后我尝试了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
)

现在我的目标是在$result中获取Cookie，但它是空的＆amp;什么都没有回归

是否在cURL命令等效的PHP代码中缺少某些内容？

有人可以帮助我吗？指出我要检索cookie的方向

非常感谢！

更新

我在请求中添加了curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);，使其在成功登录后遵循302重定向

但是这次执行cURL后，echo $result正在将我当前的本地网页重定向到/Dashboard?viewInfo=，这显然不存在

此时var_dump($result);导致：string(1462) " "

而curl_getinfo($ch)这次给出了以下数组：

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，请帮忙！

如果您想使用curls给定的功能，您可以尝试使用CURLOPT_COOKIEJAR / CURLOPT_COOKIEFILE来存储和获取您的cookie。这个if if file。在这种情况下，curl将在文件中写入任何Cookie相关信息。

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

如果您的登录有效，您将把所有信息存储在您的cookie文件中。

现在，您可以使用curlopt CURLOPT_COOKIEFILE再次使用该cookie以用于将来的请求。

// 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);

PHP - 使用cURL从重定向URL获取cookie但没有得到响应
