Sessions and cache being used when both set as disabled

How did you disable cache in app.php?

In your .env file you probably set your CACHE_DRIVER to something you didn't set up. Just set it to CACHE_DRIVER=file if you will not be using any caching mechanism.

I had this issue yesterday and setting the session driver to file worked for me.

Yeah just checked. The default setting is memcached. So if you don't set it up you get the error.

https://github.com/laravel/lumen/blob/master/.env.example

You can change both to file for development and testing. But for production I would change the SESSION_DRIVER to something else.

@martink8, @alenabdula - Where in the docs do you find this information? I read through http://lumen.laravel.com/docs/cache#configuration and it isn't there.

As how I disabled it I followed some instructions to leave the following lines uncommented in app.php

// $app->middleware([
//     // Illuminate\Cookie\Middleware\EncryptCookies::class,
//     // Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
//     // Illuminate\Session\Middleware\StartSession::class,
//     // Illuminate\View\Middleware\ShareErrorsFromSession::class,
//     // Laravel\Lumen\Http\Middleware\VerifyCsrfToken::class,
// ]);

I changed the .env entries to the following...

CACHE_DRIVER=file
SESSION_DRIVER=file

And I get the following error message using the postman extension for Chrome to send a POST form request to test an endpoint

MethodNotAllowedHttpException in Application.php line 1188:

at Application->dispatch(null) in Application.php line 1084
at Application->run() in index.php line 28

Any ideas as to the source of this error?

This is the session middleware. The Cache still gets started up (you can't disable it) and since you have it set to something else than file you need to configure it. I don't think its anywhere in the docs.

Copy the routes.php and the appropriate controller if you are using one. I need more information :)

@martink8 - I meant where in the docs is CACHE_DRIVER=file explained? Because having to learn how to get Lumen working by posting questions to the forums, rather than the online documentation is too costly in time.

from routes.php

$app->group(['prefix' => 'api/v1','namespace' => 'App\Http\Controllers'], function($app) {
    $app->get('accounts', ['as'=>'accounts', 'uses'=>'AccountController@accounts']);
    $app->get('accounts/{id}', ['as'=>'get_account', 'uses'=>'AccountController@getAccount']);
    $app->post('accounts', ['as'=>'accounts', 'uses'=>'AccountController@createAccount']);
    $app->put('accounts/{id}', ['as'=>'accounts', 'uses'=>'AccountController@updateAccount']);
    $app->delete('accounts/{id}', ['as'=>'accounts', 'uses'=>'AccountController@deleteAccount']);
});

and from AccountController.php

    public function createAccount(Request $request)
    {
        $this->validateRequest($request);
        $Account = Account::create($request->all());
    return response()->json($Account);
}

Oh I am sorry, didn't get ya there. It's explained in the docs - http://lumen.laravel.com/docs/cache#configuration - on how to use redis, memcached and database.

Although the file part is left out. It is mentioned in the Laravel docs: http://laravel.com/docs/5.1/cache#configuration

I think the default option here should be file, but for whatever reason it's set to memcached. No idea why.

Everything seems ok. Try using dd() before doing anything else in the controller and see what happens or debugging a little :)

@martink8 - Thanks for the update.
