使用GuzzleHttp从HTTP调用获取cookie的值

Question

I am now using GuzzleHttp to make HTTP requests, first I make a POST request to login.asp, which returns a response with Set-Cookie with a value that I need for future requests

When I inspect my obtained answer I get the following

As noted, I get all the keys except the Set-Cookie, what can be happening? How can I get this value? I'm using "guzzlehttp/guzzle": "^6.3", or can I get it using another tool?

    $jar = new CookieJar;

    $client = new Client([
        'base_uri' =>'miurl/',
        'timeout'  => 10.0,
        'cookies' => $jar
    ]);

    $response = $client->request('POST', 'login.asp',  [
        'form_params' => [
            'pws' => '',//data password
            'user' => '',//data user
        ]
    ]);

    //Request require coookies

    $response = $client->request('POST', 'goform/Wls',  [
        'form_params' => [
            /*Form´Params*/
        ],
       //if I manually add a correct userid the post application works fine
        'headers' => [
            //Require cookie param userid 
            'Cookie' => 'LANG_COOKIE=lang_span; userid=1524324306',
        ]
    ]);

Alternatively, I used this configuration without being able to obtain the cookie yet

checking a bit the answer using postman, is that after doing the correct login is still on the same page but with javascript redirect, can this influence?

<script language='JavaScript'>window.location='/admin/cable-Systeminfo.asp';</script>
</html>

The requests I make directly for a router hitron technologies cgnv22 to manage the mac filtering, I would like to provide more information but it is sensitive information

It seems you're making the request the right way, passing an instance of CookieJarInterface. However, you shouldn't expect the Set-Cookie header. Instead, inspect your jar to check what cookies were returned.

The following example shows how you can iterate over all cookies:

$client = new \GuzzleHttp\Client();

$jar = new \GuzzleHttp\Cookie\CookieJar();
$request = $client->request('GET', 'https://www.google.com/', [
    'cookies' => $jar
]);

$it = $jar->getIterator();
while ($it->valid()) {
    var_dump($it->current());
    $it->next();
}

Here is a sample output from the snippet above:

object(GuzzleHttp\Cookie\SetCookie)#36 (1) {
  ["data":"GuzzleHttp\Cookie\SetCookie":private]=>
  array(9) {
    ["Name"]=>
    string(3) "NID"
    ["Value"]=>
    string(132) "130=dmyl6v*******"
    ["Domain"]=>
    string(11) ".google.com"
    ["Path"]=>
    string(1) "/"
    ["Max-Age"]=>
    NULL
    ["Expires"]=>
    int(1542242169)
    ["Secure"]=>
    bool(false)
    ["Discard"]=>
    bool(false)
    ["HttpOnly"]=>
    bool(true)
  }
}

Refer to the CookieJar class source for more information on how you can access the returned cookies. Additionally, you can take a look at the docs for ArrayIterator class.
