获取PHPUnit ajax测试的cookie

Question

I'm trying to write some PHPUnit tests for ajax endpoints. I can do this no sweat when the user doesn't have to be logged in. But to test the endpoint in question, the user does have to be logged in and I want to get the cookie programmatically as part of the test. Basically the test I want to run looks like:

    $url = "https://example.com/ajax/endpoint";
    $fields = array(
        'name'=>'test '.rand(),       
        'host'=>rand(0,255).'.'.rand(0,255).'.'.rand(0,255).'.'.rand(0,255),
        'port'=>rand(1,1000)
    );
    $fields_string = "";
    foreach ($fields as $key=>$value) {
        $fields_string .= $key.'='.$value.'&';
    }
    $fields_string = rtrim($fields_string, '&');
    ob_start();
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_COOKIE, $userCookie);
    curl_setopt($ch, CURLOPT_URL, $url);
    $response = curl_exec($ch);
    $this->assertEquals(true, $response);
    $json = ob_get_contents();
    $return = json_decode($json);
    $this->assertEquals('false', $return->success);
    $this->assertEquals('', $return->data);
    ob_end_clean();

But I don't know a good way to get $userCookie other than opening a browser, logging in, and then reading PHPSESSID from the cookies in the browser. How can I get the cookie for this without grabbing it manually? I'd like to be able to get it from a curl request to the login endpoint:

    $url = "https://example.com/ajax/login";
    $fields = array(
        'username'=>$username,
        'password'=>$password
    );
    $fields_string = "";
    foreach ($fields as $key=>$value) {
        $fields_string .= $key.'='.$value.'&';
    }
    $fields_string = rtrim($fields_string, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_URL, $url);
    $response = curl_exec($ch);

Does anything stop you to grab it programmatically?

$ch = curl_init('https://example.com/login');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "login=root&password=toor");
curl_setopt($ch, CURLOPT_HEADER, 1);

$result = curl_exec($ch);
preg_match_all('/^Set-Cookie: PHPSESSID=(.*?);/mi', $result, $matches);
$userCookie = $matches[1];
