And while a bit off topic, I think the api-platform might be a more widely used approach. I've tried out with both methods and none of them work. Api platform is good but I need a custom controller.

I'd say it looks like your project is broken. The recipe is supposed to create this file. Try to reinstall the whole project. If it still does'nt work post your composer. Glad you got something working. Might want to look at JsonResponse as well. But just so you know, this solution is just the "out of the box" Symfony solution. Nothing to do with the api bundle.

Related Hot Network Questions.Users want progressive web applications and seamless experiences across every device. The focus is shifting from monolithic code to APIs built as microservices and consumed by multiple frontends, and finding our way through the ecosystem of ever-changing tools can be a daunting task even for the most experienced of us. JavaScript, on the other hand, is changing so dramatically that by the time I finish writing this article a new framework will probably emerge, become fashionable and fade away.

You will also need an Okta developer account. Okta is an API service that allows you to create, edit, and securely store user accounts and user account data, and connect them with one or more applications.

Symfony 4 : Authentication (Login page)

Our API enables you to:. You can add a new movie and increase the bad puns count of movies while watching them. Symfony 4 is the latest release of the Symfony project which started as a collection of general purpose components for PHP. These components are widely used on their own, and the most popular PHP framework today Laravel is largely built upon them. Symfony 2. It provides a new method of creating and evolving applications Symfony Flex which starts with a minimum set of dependencies and automates the bundle management.

You can start with a skeleton project with a greatly simplified directory structure and add just what you need, when you need it. However, I will show you the basics of setting up an API without any dependencies apart from the micro framework we already installed. This looks better. Now we can use the respond method to return a JSON response with the default status code ofand a respondUnauthorized method to return a Unauthorized response with an appropriate error message.

Now we can set up our entity. We need the Doctrine ORM pack and the maker-bundle which can help us generate some code. Now we have an entity, a migration, and the database schema has been migrated. We can create our API endpoints and test them via Postman or a similar client. Now we have a nice blank page. Much better! Before you proceed, you need to log into your Okta account or create a new one for free and set up a new OIDC app.

Make sure to take note of your Okta domain and the Client ID generated for the app. You can leave the rest of the settings as they are. When done with the prerequisites, we can install the Okta Vue SDK and modify our Dashboard to include a Login or Logout link depending on the authentication state. The next step is to secure the backend API. Now we need to secure our controller methods. The application is fully functional at this stage. As a next step, we need to clean up the code as there is a lot of repetition especially in the handling of AJAX requests at the frontend.

Hit us up in the comments, or on Twitter oktadev! Why Okta? Our API enables you to: Authenticate and authorize your users Store data about your users Perform password-based and social login Secure your application with multi-factor authentication And much more!

Now let's add some fields!In this example, we'll build an API token authentication system, so we can learn more about Guard in detail. Your job is to read this and find the associated user if any. First, make sure you've followed the main Security Guide to create your User class.

Then, to keep things simple, add an apiToken property directly to your User class the make:entity command is a good way to do this :. To create a custom authentication system, create a class and make it implement AuthenticatorInterface.

Or, extend the simpler AbstractGuardAuthenticator. Nice work! Each method is explained below: The Guard Authenticator Methods. To finish this, make sure your authenticator is registered as a service. If you're using the default services. Finally, configure your firewalls key in security. You did it! You now have a fully-working API token authentication system.

The message will be different based on where authentication fails i. You can throw this from getCredentialsgetUser or checkCredentials to cause a failure:. Sometimes you might want to manually authenticate a user - like after the user completes registration. To do that, use your authenticator and a service called GuardAuthenticatorHandler :. If you create a Guard login system that's used by a browser and you're experiencing problems with your session or CSRF tokens, the cause could be bad behavior by your authenticator.

When a Guard authenticator is meant to be used by a browser, you should not authenticate the user on every request. In other words, you need to make sure the supports method only returns true when you actually need to authenticate the user.

Because, when supports returns true and authentication is ultimately successfulfor security purposes, the user's session is "migrated" to a new session id.

This is an edge-case, and unless you're having session or CSRF token issues, you can ignore this. Here is an example of good and bad behavior:. The problem occurs when your browser-based authenticator tries to authenticate the user on every request - like in the IP address-based example above.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Dark Mode Beta - help us root out low-contrast and un-converted bits. Technical site integration observational experiment live on Stack Overflow.With Symfony, I used to build my web applications in a traditional way: the framework handles everything, from the routing to the page rendering. However nowadays web applications have complex user interactions and the previous approach does not fit well for such cases. That's where single-page application architecture comes to the rescue.

A single-page application SPA is a web application or web site that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server. This approach avoids interruption of the user experience between successive pages, making the application behave more like a desktop application.

In others words, it's a lot easier to keep the context data and so on of our application in our frontend while navigating between our pages. If you have struggled with complex forms in advanced UI, you may understand the possibilities. In this tutorial, we'll build a very simple application where users can post messages.

We'll see how to:. This file will help us to store the shared environment variables of our containers and secrets we don't want to commit. As Docker Compose is only able to read those values from a file named. For instance:. We begin by adding a reverse-proxy Traefik here which will redirect any incoming requests to a virtual host to the correct container:. We're using here an image based on the official PHP image, but more complete for our developer needs:.

Also, we added some labels on this container. Those labels are used by our Traefik container to know on which virtual host a container is linked. As you can see, in a Docker context, the hostname of your database is actually the name of the MySQL service defined in your docker-compose.

You may also notice that we mount the file located at. But as we're using Docker, we have put directly those values in our docker-compose. As we're using Docker, we may send them to the Docker output:. You may now run those scripts by using composer csfix and composer cscheck!

PHPStan focuses on finding errors in your code without actually running it. It catches whole classes of bugs even before you write tests for the code. First, TheCodingMachine strict rules see our blog post for more details :.

A set of core PHP functions rewritten to throw exceptions instead of returning false when an error is encountered. Alright we're good for this part! Symfony provides a simple abstraction for this tool which fits well in a Symfony context: Webpack Encore. Let's add ESLint for some formatting and code-quality rules:. Let's start by removing all folders from the assets folder. They have been created by Webpack Encore and we don't need them.

Right now we can't use those files directly as they can't be interpreted by our browser. Thanks to Webpack Encore, we are able to build a browser comprehensive output file with:. In the templates folder, there is a file named base. If you go to app. But this tutorial is about single-page application: our Vue.You may unsubscribe at any time using the unsubscribe link in the digest email.

Download the latest compressed. Then extract it inside of our working directory and run the commands below:. In order to start the containers, run docker-compose up -d. You should expect to view the following screens:. Your API dashboard will now be empty once you reload your browser.

This model will be responsible for storing the items of our bucket list. Add the following lines of code:. Next, we need to navigate into the PHP container and run migrations in order to update the database with the newly created models.

Log into your preferred Postgres client and confirm if the table has been created. Here is my table and all the fields have been created. After confirming the models have been created, it's now time to create endpoints with CRUD operations. Our class will look like:. How cool is that? A new bucketlist should now be created and persisted to the database.

The response code returned is representing that a new resource has been created. Let's utilize the GET method to retrieve the bucketlist created. In my case, I have retrieved the bucket list with id 4. Suppose a user wants to retrieve a resource that doesn't exist, for example, a bucketlist with 9. The resulting status code is with the error message, Not Found. API Platform takes care of such validations out of the box.

Deleting a bucketlist is also straight forward.

API Platform

If that resource does not exist, a status code of is returned. The final part would be editing a particular bucketlist.As the framework evolves into new releases there might be some changes in methodsclasses and tools. They may become deprecated or obsolete and new tools may be added, although some kind of retrocompatibility may be assured.

As a prerequisite for this tutorial I advice you to install Xampp as environment for the application and a good editor such as Visual Studio Code. The first thing to do after installing Xampp is to create a Virtual Host and edit your hosts file. Next we can setup our project and install all the necessary dependencies, do it like this at your shell:.

For our purposes we have to edit the. Type those values when asked by the following command:. As you can see it is also generating all the getters and settes. And again, we have to create an ArticleType class, to make up our form. Another difference you may have noticed from the previous tutorial is the use of a separate class for building our form.

That allows us to remove clutter from the controller class, making it more readable. And we will be able to reuse the form class code around all the application, should we need to.

The rest of the code is similar and reflects also a different directory structure of Symfony 4 compared to the 3rd version. Contact meshould you have any question.
