getting this error after install jwt

php artisan jwt:secret

There are no commands defined in the "jwt" namespace.

Had the same issue.

following the docs here jwt-auth.readthedocs.io/en/develop...
especially the chapter Bootstrap file changes fixed the issue

Add the following snippet to the bootstrap/app.php file under the providers section as follows:

// Uncomment this line
$app->register(App\Providers\AuthServiceProvider::class);

// Add this line
$app->register(Tymon\JWTAuth\Providers\LumenServiceProvider::class);

Ndifreke Friday • Oct 16 '19

Please check to make sure tymon/jwt-auth installed successfully

Also type php artisan to see available commands.

Keep me posted on your progress.

Ndifreke Friday • Oct 16 '19

Side note: the command jwt:secret updates your .env file with something like JWT_SECRET=secretkeystring.

"It is the key that will be used to sign your tokens. How that happens exactly will depend on the algorithm that you choose to use."

now it's working. Thank you.

Ndifreke Friday • Oct 17 '19

You are welcome

Chris Leathley • Oct 31 '19 • Edited

you might want to also add

use Illuminate\Support\Facades\Auth;

when you add respondWithToken to app/Http/Controllers/Controller.php (Lumin 6+)

Cabello, Hector Guillermo • Nov 5 '19

This is key.

I was followed step by step your tutorial, writing the code by myself (i mean, without clone your github project) and without this line (thanks @cleathley ) an error appears.

I think you should edit your post and add that line after you explain this:
«Add a global respondWithToken method to Controller class»

Anyway, great tutorial. It help me a lot!!

Ndifreke Friday • Nov 6 '19 • Edited

I'm glad it helped 👍

I will update the post, so new readers don't run into this same error.

Ndifreke Friday • Nov 6 '19

Thanks For this, I will update the tutorial to help people not encounter this error in the future.

First of all great tutorial, thanks a lot for all your efforts dude, I've a question, how can I set a remember me system with JWT token ? And also, how to increase expiration duration from the config file (config/auth.php) ?

Ndifreke Friday • Nov 26 '19 • Edited

Would there be a need for remember me? As long as the client has the token; they have access to the system.

You could extend token's time to live for those type of users, that could work...I think.

Override the token ttl
$token = auth()->setTTL(7200)->attempt($credentials);

Walid Yacine MAZED • Dec 15 '19 • Edited

Thanks dude, I've another question please, if the token is stocked localy, then yo access protected area I've check the user token for that, if Auth::user() did the job, why we stock the token localy ?

Walid Yacine MAZED • Nov 25 '19

For the second part of the question, the answer should be:

Getting this error,

In Connection.php line 665:

In Connector.php line 70:

Using Homestead development environment.

Ndifreke Friday • Nov 26 '19 • Edited

This error is due to PHP not being able to connect to MySQL

"Create a .env file, copy all contents in .env.example into the .env file and add your database configurations."

racedaemon • Oct 5 '20

This was of great help. The only problem I encountered was when running php artisan jwt:secret.
$app->register(Tymon\JWTAuth\Providers\LumenServiceProvider::class); needs to be added to app.php before the command is executed.

Fongoh Martin T. • Nov 21 '19

Nice tutorial, very clear and straight to the point. My worry is why the dev-develope branch? The main branch, does it have an issue?

Ndifreke Friday • Nov 26 '19

For some reason the dev-develop branch has always worked for new versions of lumen, the next best thing would be version @2.0-dev

Fongoh Martin T. • Nov 26 '19

Ok thanks. I tried using the default and it keeps failing and when i use dev-develop, it worked well.

Thanks again for the tutorial, nice, easy and straight to the point.

I come again with one question. If i log into different devices, eg 4 different clients and have 4 different tokens, will all 4 be valid simultaneously? If not, what will you suggest to be done to ensure multiple tokens are valid across different devices.

Ndifreke Friday • Nov 26 '19

Every Token Generated that is yet to expired is valid; So yes, a user can have multiple tokens across multiple devices.

executions12 • Oct 21 '19

everything except php artisan jwt::secret is work...
so, i write jwt key in .env by myself..

thank you, nice tutorial...

jaimin-hothi • Oct 9 '20 • Edited

Hi,
Thanks for your great tutorial.
But I want a custom field (email and password) both so could you make it an example for that.

My field name = USER_NAME, PASSWORD (Both are capital)

I try but token always false.

If you do then its great help for me.

Thank you
