我的Laravel会话cookie没有在浏览器中设置，即使服务器响应包含正确的Set-Cookie报头。Laravel服务器运行在localhost：8000，客户端应用程序是NuxtJS SPA，运行在localhost：7000。
包含Set-Cookie的响应报头如下所示：

通过postman发出同样的请求，cookie被保存：

因此，浏览器似乎忽略了“Set-Cookie”标头。
我的session.php文件如下所示：

<?php

return [
    'driver' => env('SESSION_DRIVER', 'redis'),
    'lifetime' => env('SESSION_LIFETIME', 120),
    'expire_on_close' => false,
    'encrypt' => false,
    'files' => storage_path('framework/sessions'),
    'connection' => env('SESSION_CONNECTION', null),
    'table' => 'sessions',
    'store' => env('SESSION_STORE', null),
    'lottery' => [2, 100],
    'cookie' => 'dv_session',
    'path' => '/',
    'domain' => "",
    'secure' => false,
    'http_only' => false,
];

为什么cookie保存在Postman中，但被浏览器忽略？
