Question

Nginx converts POST request to GET request Laravel

I have a running a Laravel project on Nginx, every thing works fine except when I want to login via the API, I use Passport for authentication, but when I try to login it returns with 404 and a message “The GET method is not supported for this route. Supported methods: POST.”, although it works fine via php artisan serve

Here is my request: URL: http://my_droplet_ip/oauth/token Body:

{
    "username": "user_name",
    "password": "secret",
    "client_id": 3,
    "client_secret": "client_sercret",
    "grant_type": "",
    "scope": "*"
}

The response :

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException: The GET method is not supported for this route. Supported methods: POST. in file /home/nginx/zacampus/vendor/laravel/framework/src/Illuminate/Routing/AbstractRouteCollection.php on line 117

I solved it by adding SSL certification to the server and enabling HTTPS in server configuration.

Hi there @abdelnasserahmed96,

What is the main reason for having the location /oauth/token part in the Nginx config?

    location /oauth/token {
        try_files $uri $uri/ = 404;
    }

As a test what I could suggest is using the Nginx configuration provided by the official Laravel Documentation, and then gradually adding the additional configuration settings that you have one by one to see which of those could be causing the issue for you.

Let me know how it goes! Regards, Bobby
