11 - Symfony 4 REST: JWT API Authentication

[@MrYousip]

Hey ! Thank's for that wonderfull tutorial :D ! If anyone have trouble with postman to test the api/login_check use "raw" format instead of "form-data" it worked for me !

[@OverSeasMedia]

Goddamn it where were when I was trying to use postman . Lol . Thanks man . I will pin this for anyone using postman . Cheers mate :)

[@arbitruVAR]

I resolve this issue with change tha security.yaml at he firewalls proparty from data_login to json_login.

[@scorpioniz]

wanted to write the same :D

[@Mr8perezm]

This video you created was super useful. I've been trying to lock down an API in Symfony for weeks now. Your vid allowed me to actually complete the task and hopefully please the boss. Thanks, keep making them.

[@OverSeasMedia]

Aye mate you're really welcome, of you ever get stuck and need help directly please let me know, I know what is like to be stuck and frustrated by a deadline and I'm willing to help when possible :)) Cheers :))

[@customphpdesign]

Thank you!!! After getting the token its just like dealing with a user who is logged in. You can check and restrict roles as normal. Was looking for a easy to use API for Symfony 5 and this works great!

[@davidramentol4877]

Just to clarify: OAuth2 and JWT are not exclusive, the first one is an authorization standard and the second one is token standard. You would usually use both together.

[@tark6392]

Thank you so much! Newbie for symfony. My question is how did you get the hash password? Or how to create superadmin password? Thank you!

[@OverSeasMedia]

You're most welcome, the password can be generated using a command, just type php bin/console security: encode-password and enter your pain text password and it will give you back the hashed password, and just enter it in the database manually :)

[@AinUlHUniverse]

@@OverSeasMedia make sure to remove space between "security:" and "encode-password".

Brilliant video. I don't think it can be explained better. Thank you!

Hello my problem => Unable to find the controller for path "/login_check". The route is wrongly configured.

[@nurimustafa3817]

I got error Unable to find the controller for path "/api/login_check" because I tried to post using Postman with content type x-www-form-urlencoded. In Postman when you select Body type as RAW type, it gives you selection to set data type as JSON, then you enter you data as JSON. Doing this will fix controller error

[@OverSeasMedia]

Yes that is indeed the case . You need to make sure the content type is of type json otherwise the authentication bundle won't know how to deal with your request . Cheers and thank you for sharing this with us :)

[@mani874247]

Nice tutorial. Please, how I can generate the password hash, so I can fellow with the rest of the material ?

[@OverSeasMedia]

There is a command that helps you generate the hash it's php bin/console security: encode-password

When i get token and try to insert the token in the header authorization bearer i got 401 token not found .

[@dahlizahmed4779]

Hi, Thanks for the video ! I have question and is : can you make the time of the token unlimited ?

[@sebastiendaireaux2794]

Hie, I know this video was done there is one years I have a question, is it possible to customize the response... I would like to have something in response like this : {"token": "blablabla", "user":"myUserName", "role":"myRole"}

[@OverSeasMedia]

Sorry just got a notification about this, I can't remember exactly whether you can pass the extra data the way you did, or you'd need to add any additional data into the payload (the token) it self and then read the data from the token, it's one of those things I just can't remember exactly, sorry. xD

[@AnaisUrlichs]

When I try to register the token with $ curl -X POST -H "Content-Type: application/json" localhost:8000/api/login_check -d '{"username":"username","password":"password"}' I alway get{"code":401,"message":"Bad credentials"} (I placed the information of the registered user in the database; for username -- the email, and for password -- the password); any ideas?

[@OverSeasMedia]

Hey again, I know this might sound stupid, but make sure that your MySQL server or whatever you're using is up and working (Check yourself for that), also make sure that the information that you have in the database is correct, specifically the password, if you have a registration page then that would be fine, if not then you can manually encode the password by using the following command "security:encode-password". If none of the above actually helped let me know, Good luck :)

[@AnaisUrlichs]

@@OverSeasMedia Thank you for the reply. This might be interesting for others, too. I configured everything right (used XAMPP & phpMyAdmin) etc. I was able to set up the user via curl but always got errors when I wanted to generate the token, or an empty array; also Postman only returnerd an empty array instead of the token. In the end, I was able to read the token in the header on Postman. Thanks for the help tho -- your videos are awesome!

[@nurimustafa3817]

Hi, how can I get authenticated user in a Controller?

[@OverSeasMedia]

You can use $this->getUser() . If no user is authenticated then this will return null .

[@MegaJuandelgado]

Hola y gracias ... Tengo una pregunta, ¿cómo puedo personalizar la consulta del usuario, por ejemplo, verificar si el usuario está activo?, where you can customize that query?

[@ivramuito]

where do i install openssl?

[@richardgonzalez1191]

I am getting the token perfectly, but I also need to get the time that the token lasts

[@jonatham1]

Thanks, you are the master of Symfony.

[@adamyoussef6880]

Hi, I've got a certainly stupid question. Is check_path that is used (that is "/login/api_check") a random one or it is required by lexik bundle? Is there a /login/api_check route assigned to some controller somewhere in the project that handles the check?

[@joshualim5587]

[@johngord752]

Thanks for the video. This sort of info is hard to find for some reason. You would think that something as common as API authentication or even just authentication in general would be better documented. The API-Platform documentation on this has their own way of doing it, insisting on using docker for everything, and leaving out important parts.

[@alamarnissi529]

Thanks bro for this awesome tuto

[@OverSeasMedia]

When that sort of thing happens . The first thing you need to do is make sure that in your security.yaml file the global pattern is the last thing in the list . If you have API/login and API/ , then make sure the login thing is before the API/, just as a first step .
