Post Request Error in Laravel 5.7: Troubleshooting 419 Sorry, your session/page has expired
Laravel 5.7 has introduced a middleware that verifies CSRF tokens. This protects your application from cross-site request forgery attacks. However, it can also lead to "419 Sorry, your session/page expired" errors if the token check fails.
Verifying the CSRF Token
Ensure that your form contains a CSRF token verifier:
Session Configuration
Verify your session configuration in the .env file. Supported session drivers include:
- file
- cookie
- database
- memcached
- redis
- array
If switching the session driver resolves the issue, it indicates a problem with the previous driver. Troubleshoot the driver's configuration.
Possible Error Scenarios
- File-based sessions: Check file permissions for the /storage directory.
- Database driver: Confirm your database connection and the existence and correctness of the sessions table.
- Redis/memcached: Ensure that the configuration is accurate and that other code is not manipulating it.
Other Troubleshooting Steps
- Generate a new application key using php artisan key:generate to flush session data.
- Clear the browser cache, as Chrome and Firefox can contribute to the issue.
- Consider why application keys are important, especially when encountering errors related to CSRF token verification.
