419 page expired laravel page in iframe-CodePudding

I am opening a page developed using Laravel-7 inside an iframe in an angular project. The page is displaying the records. But while creating or updating a record the page throws 419 error.

I have update the 'same_site' => 'none' and it didn't help.

Both projects are deployed in GCP

I have attached my session.php file .

<?php

use Illuminate\Support\Str;

Please help me to fix this issue.

CodePudding user response：

It should work if you try all of these steps:

Ensure that your session is well configured, the easiest way is to make it file and make sure storage folder has chmod 755 permission then in your .env you set it like below, file session driver is the easiest way to set.
```
SESSION_DRIVER=file
SESSION_DOMAIN=
SESSION_SECURE_COOKIE=false
```
Ensure Cache folder is cleared and writable, you can do this by running below artisan command.
```
php artisan cache:clear
```

Ensure folder permissions are well set, they should be configured like below:

sudo chmod -R 755 storage
sudo chmod -R 755 vendor
sudo chmod -R 644 bootstrap/cache

Ensure your form has @csrf token included.

Hope this will solve your problem.

CodePudding user response：

One simple approach would be exclude the URIs that are causing the CSRF problem:

// FILE: App\Http\Middleware\VerifyCsrfToken

// The URIs that should be excluded from CSRF verification
// URI is the first param you pass to the Route facade

protected $except = [
    'create/record', 'update/record'
];

Your route file might look like this:

Route::post('create/record', ....)
