Php Artisan Jwt Key Generator

The JSON Web token usually remains valid for 3600s or one hour. Nowdays API’s are mostly developed with JWT authentication. Generate JWT Key. Recent testing in both 0.5.9 and 0.5.12 indicates that the jwt:generate command ONLY changes the value in config/jwt.php IFF it is the key in use. To see this for yourself, set the value in.env to be the same as in config/jwt.php and it WILL change the one in config the first time you run it but then it will break. A bit of searching indicates that the dev has no plans to fix this for 0.5. In this tutorial I’ll cover how to setup JSON Web Token authentication using Laravel and Vue JS. The tutorial will have two parts. To generate JSON Web tokens from the Laravel backend we’ll be using the popular library tymondesigns/jwt-auth by Sean Tymon. Run php artisan jwt:secret to enerate the secret key. Mar 31, 2016 Laravel 5.2 API using JWT authentication tutorial from scratch example. We have to generate jwt key, fire bellow command on your terminal. Php artisan jwt. Nov 05, 2019  JWT stands for JSON Web Token and is an open standard to securely transmitting information between different parties. JWT authentication token will be signed with an encryption key, run the following command to generate the secret key used to sign the tokens.

In this article, we will learn how to build restful API in Laravel using JWT Authentication. JWT stands for JSON Web Tokens. We will also create a fully functional CRUD for user products using API.

API’s are great when working with cross-platform applications. In addition to a website, your product may have an android and iOS app. In such cases, API’s are great because you can write different front ends without changing any backend code. When working with API, you simply hit a GET, POST or different kind of request with some arguments and server returns some data in JSON (JavaScript Object Notation) format which is handled by the client-side application.

Details

Let’s first write down our application details and features. We will build a basic user products list with restful API in laravel using JWT authentication.

A User will be able to

  • sign up and create a new account
  • log-in to their account
  • log out to discard the token and leave the application
  • get the details of the logged in user
  • retrieve a list of products available for the user
  • find a specific product by id
  • add a new product to the user product list
  • edit an existing product details
  • delete an existing product from the user list

A User requires

  • name
  • email
  • password

A Product requires

  • name
  • price
  • quantity

Creating a new project

Let’s start by creating a new laravel project by running the following command.

It will create a new laravel project in the folder named jwt.

Configuring JWT Package

We will be using tymondesigns/jwt-auth package for working with JWT in Laravel.

Installing tymon/jwt-auth package

Let’s install this package in our Laravel application. If you are using Laravel version 5.5 or above, run the following command to require a dev-develop version of jwt package.

https://healthclever922.weebly.com/blog/tex-download-mac-os-x. If you are using the laravel version 5.4 or less, run the following command

For versions less than 5.5, you are also required to set service provider and alias in config/app.php file.

If you are using version 5.5 or above, laravel does it automatically using Package Auto-Discovery.

Publishing Configuration File

Publish the configuration file using the following command for versions 5.5 or above

If you are using previous versions of laravel, run the following command to publish the configuration

Above command will generate a config/jwt.php configuration file. Here’s the configuration file without any comments.

Generate JWT Key

JWT tokens will be signed with an encryption key. Run the following command for laravel 5.5 or above to generate the secret key used to sign the tokens.

For versions below 5.5Microsoft office 2016 home and student product key generator.

This tutorial uses laravel 5.6. Next steps of the tutorial are only tested for laravel 5.5 and 5.6. Tutorial steps below may not work for laravel 5.4 or less. You may consider the documentation for laravel previous versions.

Registering Middleware

JWT auth package comes up with middlewares that we can use. Register auth.jwt middleware in app/Http/Kernel.php

This middleware verifies that the user is authenticated by checking the token sent with the request. If the user is not authenticated, the middleware will throw UnauthorizedHttpException exception.

Set up Routes

We will set up routes for all the endpoints that we discussed at the start of the tutorial. Open up routes/api.php and copy the routes below to your file.

Update User Model

JWT requires implementing the TymonJWTAuthContractsJWTSubject interface on the User model. This interface requires implementing two methods getJWTIdentifier and getJWTCustomClaims. Update app/User.php file with the contents present below.

JWT Authentication Logic

Let’s write the logic for restful API in laravel using JWT authentication.

User registration requires name, email, and password. So, let’s create a form request to validate the data. Create a Form request named RegisterAuthRequest by running the following command:

It will create RegisterAuthRequest.php file in app/Http/Requests directory. Paste the code below into the file.

Create a new ApiController by running the command:

This will create the ApiController.php file in app/Http/Controllers directory. Paste the code below into the file.

Let me explain what’s happening in the code above.

In the register method, we accept RegisterAuthRequest. A user is created with the data present in the request. If the loginAfterSignUp property is true, it will log-in the user by calling the login method after registering. Otherwise, a successful response is returned with the user data.

In the login method, we get a subset of the request only containing email and password. JWTAuth::attempt() is called with input as the argument and the response is saved in a variable. If false is returned from the attempt method, we return a failure response. Otherwise, a success response is returned.

In the logout method, the request is validated that it contains the token field. The token is invalidated by calling the invalidate method and a successful response is returned. If the JWTException exception caught, a failure response is returned.

In the getAuthUser method, the request is validated that it contains the token field. Then the authenticate method is called which returns the authenticated user. Finally, the response with the user is returned.

Authentication part is now complete.

Building the Product Part

To create the product part, we will need a Product model, controller, and migration. Run the following command to create the Product model, controller, and migration.

It will create a new database migration file create_products_table.php in database/migrations directory. Update the up method.

Add a fillable property to the Product model. Open the Product.php file in the app directory and add the property.

Now set up your database credentials in the .env file and migrate the database by running the following command.

Now, we have to add a relationship in the User model to retrieve the related products. In app/User.php add the following method.

Artisan

Open the ProductController.php file in app/Http/Controllers directory. Add the following use directives at the beginning of the file overwriting the previous one.

Now we will implement five methods.

  • index, to get a list of all the products for the authenticated user
  • show, to get a specific product by its id
  • store, to store a new product to the list of products
  • update, to update product details by its id
  • destroy, to delete a product from the list by its id

Add a constructor to get the authenticated user and save it in the user property.

parseToken will parse the token from the request and authenticate method will authenticate the user via the token.

Let’s add the index method.

Above code is very easy. We are simply using eloquent to get all of the user products and then we convert the results into an array. Finally, we return it. Laravel will automatically convert it into JSON and create a 200 success response code.

Moving on to implement the show method.

This one is also easy to understand. We simply find the product with the id. If the product is not present, a failure 400 response is returned. Otherwise, the product is returned.

Next method is the store method.

In the store method, the request is validated that it contains name, price, and quantity. Then, a new Product model is created with the data present in the request. If the product is saved successfully in the database, a success response is returned. Otherwise, a failure 500 custom response is returned.

Let’s implement the update method.

In the update method, we find the product with the id. If the product is not present, a 400 response is returned. Then we update the product details with the details present in the request by using the fill method. Updated product model is then saved in the database. If the record updates successfully, a 200 success response is returned. Otherwise, a 500 internal server error response is returned to the client.

Now, let’s implement the destroy method.

In the destroy method, we find the product with its id. If the product is not present, a 400 response is returned. Then we delete the product and return an appropriate response based on the success of the delete operation.

The controller code is now complete. Here is the full controller code.

Testing

Let’s first test the authentication process. We will be using serve command to serve the application on the development server. You can use virtual host if you want. Run the following command to serve the application.

It will start a development server at localhost:8000

For testing restful API’s, we will use Postman. Let’s make a call to the register route after filling the request body.

Send the request and you will get a token back.

Our user is now registered and authenticated. We can check the login route by sending another request. It will send a 200 response with the token.

Let’s retrieve the user details.

Testing authentication is complete. Let’s test the product part. First store the product.

Now, let’s retrieve the product by requesting the index method.
