Laravel json api

The default API name is default. You must set the default API if you are not using default as the name. It is used to render error responses when clients have sent an Accept header with the JSON API media type if the exception occurs before the json-api middleware runs. If your application has multiple APIs - e. For example:. This means we cannot automatically create them via the service container without you provided verbose configuration.

Your namespace and by-resource configuration options control how we resolve fully-qualified class names. If you do not want to use our namespacing convention, check out the Resolvers chapter for how to write your own implementation. If namespace is nullthe JsonApi namespace in your application's namespace will be used.

If you want to use a different namespace, set the namespace option accordingly. The by-resource setting controls how you want to organise classes within this namespace. If this setting is truethere will be a sub-namespace for each resource type. If by-resource is falsethe sub-namespace will be the class type e. All schemas, adapters and validators are created via Laravel's container.

This means that you can use constructor dependency injection if desired. For example, if you wanted to write a generic adapter that can be used for both a posts and blogs resource, you can bind these into the service container using the expected JSON API class name:. The config also contains a use-eloquent option. Set this to true if the majority of your resources relate to Eloquent models.

The use-eloquent option is effectively a default, and can be overridden when using a generator. For example, if use-eloquent is true :. This is defined in the resources setting in the API's configuration file. For example, if your application had two Eloquent models - Post and Comment - your resource configuration would be:. This is configured in your API's configuration file under the url setting, that looks like this:. We also automatically apply them when you register routes for your API.

If the value is nullwe default to Laravel's app. Otherwise, we'll use the value you've provided. If you do not want the host to be appended to URLs in the encoded document, set url. For sub-directory installs of Laravel applications, the namespace is the URL namespace within this sub-directory, as per this issue.

For example, if the name is api:v1:then the route name for the index of the posts resource will be api:v1:posts.Written and maintained by Taylor Otwell, the framework is very opinionated and strives to save developer time by favoring convention over configuration.

The framework also aims to evolve with the web and has already incorporated several new features and ideas in the web development world—such as job queues, API authentication out of the box, real-time communication, and much more. Another requirement for the PUT verb is idempotence, which in this case basically means you can send that request 1, 2 or times and the result will be the same: one updated resource in the database.

Resources will be the targets of the actions, in our case Articles and Users, and they have their own endpoints:. In this laravel api tutorial, the resources will have a representation on our data models, but that is not a requirement. You can have resources represented in more than one data model or not represented at all in the database and models completely off limits for the user. In the end, you get to decide how to architect resources and models in a way that is fitting to your application.

Remember that the URLs should not contain verbs and that resources are not necessarily rows in a table. After you follow the download instructions and add to your path environment variableinstall Laravel using the command:.

Laravel API Tutorial: How to Build and Test a RESTful API

With Laravel installed, you should be able to start the server and test if everything is working:. Before actually writing your first migration, make sure you have a database created for this app and add its credentials to the. You can also use Homestead, a Vagrant box specially crafted for Laravel, but that is a bit out of the scope of this article.

The article should have a title and a body field, as well as a creation date. To create the Article model, we can run:. The -m option is short for --migration and it tells Artisan to create one for our model. You can also use the --step option here, and it will separate each migration into its own batch so that you can roll them back individually if needed.

Database seeding is the process of filling up our database with dummy data that we can use to test it. Laravel comes with Fakera great library for generating just the correct format of dummy data for us. The routes inside api. We can improve the endpoints by using implicit route model binding. Laravel comes with authentication out of the box, but we still need to tweak it a bit to return the response we want.

The problem is: I want him to throw a json formed array with keys "code" and "message", each one containing the above mentioned data. This will convert all errors for and to a custom json error instead of the Whoops stacktrace.

Add this:. Making an API it is best to create your own helper like Responser::error'damn' that extends the Response class. All I did was to change my render function to this:. Hope this helps :. Heres what I used in 5. According to Ibrahim's answer, not every ajax request wants JSON, Responding the "status code" and the "status" is unnecessary since they both mean the same thing.


More than that, there's no need to mention in the response "status" at all, since the response code "says" that. Something like that should work perfectly:. In Laravel5. Learn more.

For the sake of having a real life example, this configuration will guide you on how to set up 7 end-points for two resources, Employees and Orders. Both Employees and Orders resources will be Eloquent models, being related one with the other. Furthermore, Employees will be using an Eloquent feature, appended fields to demonstrate how it is possible to make the most of Eloquent and this package all together.

First, let's define the Models for Employees and Orders using Eloquent. Follow up, we'll be creating Transformers. This file should return an array returning all the class mappings. Let's create a new controller that extends the JsonApiController provided by this package, as follows:.

In case you need to overwrite any default behaviour, the JsonApiController methods are:. As the name suggests, it should list orders, so the behaviour should be the same as the one of ListAction.

laravel json api

If you look inside the listAction you'll find a code similar to the one below, but we just ajusted the behaviour and used it in our controller to support an additional action:. For instance, attachments member was hidden, but it is required, so it needs to be passed in with a valid value.

Passing and id is optional and will be used instead of a server-side generated value if provided. It's important to notice this time we are required to pass in the ideven if it has been passed in by the URI, and of course the id values must match.

Otherwise it will fail. We are required to pass in the id member, even if it has been passed in by the URI, and of course the id values must match. Sort results using sort and passing in the member names of the main resource defined in data[type] member.

Let's say we want to create a new Employee and pass in its first Order too. This could be done issuing 2 POST to the end-points one for Employee, one for Order or pass in the first Order as a relationship with our Employeefor instance:. Due to the existance of this use case, we'll have to ajust our Controller implementation overwriting some methods provided by the JsonApiController : createResourceCallableupdateResourceCallable and patchResourceCallable.

Adding custom response headers can be done for multiple reasons: versioning, setting expire headers, caching, setting private or public the served content In order to do this, it's as simple as overwriting the JsonApiController addHeaders method. For instance, let's use the EmployeeController as an example:. Double check, if missing, add it and refresh the resource.

It should be gone! The code base is licensed under the MIT license. Skip to content.

PHP Branch: master.API resources were introduced in Laravel 5. API resources is made of two entities: a resource class and a resource collection. A resource class represents a single model that needs to be transformed into a JSON structure, while a resource collection is used for transforming collections of models into a JSON structure.

Users will be able to add new books, update books and delete books. Users will also be able to view a list of all books and rate a book. Then an average rating will be computed based on the ratings on a particular book. Luckily for us, a User model already comes with Laravel by default. We define the fields for the books table which are an auto increment ID, the ID of the user that added the book, the title of the book and the description of the book.

laravel json api

Open the migration file generated for the Rating model and update the up method as below:. We define the fields for the ratings table which are an auto increment ID, the ID of the user that rated the book, the ID of the book that was rated and the rating itself ranging from Remember to enter your database details in the.

A user can add as many books as they wish, but a book can only belong to one user. So, the relationship between the User model and Book model is a one-to-many relationship. Add the code below inside the User model:. Likewise, a book can be rated by various users, hence a book can have many ratings. A rating can only belong to one book.

This is also a one-to-many relationship. Add the code below in the Book model:. To avoid getting the mass assignment error which Laravel will throw by default, we need to specify the columns we want to be mass assigned. Note: If you are using Laravel 5. This will update the.

This key will be used to sign our tokens. So add the code below to the User model:. The first method gets the identifier that will be stored in the subject claim of the JWT and the second method allow us to add any custom claims we want added to the JWT.

Here we are telling the api guard to use the jwt driver, and we are setting the api guard as the default. Now we can start to make use of the jwt-auth package. Create a new AuthController :. We define the methods to register a new user and to log users in respectively.

Both methods returns a response with a JWT by calling a respondWithToken method which gets the token array structure. Also, we define a route that will be used to rate a specified book.

When creating APIs, we often need to work with database results to filter, interpret or format values that will be returned in the API response.

API resource classes allow you to convert your models and model collections into JSON, working as a data transformation layer between the database and the controllers. API resources provide a uniform interface that can be used anywhere in the application. Eloquent relationships are also taken care of. But for both resources and collections, we have our response wrapped in a data attribute: a JSON response standard.

With the project setup, we can now start getting our hands dirty. If we peek inside the newly created resource file i. If we leave things at this, all visible model attributes will be part of our response.

laravel json api

To tailor the response, we specify the attributes we want to be converted to JSON inside this toArray method. This is because instantiating the SongResource class requires a resource instance be passed to the constructor and not a collection. If we wanted a collection returned instead of a single resource, there is a static collection method that can be called on a Resource class passing in a collection as the argument. Resources work just fine when returning a single resource or even a collection but have limitations if we want to include metadata in the response.

The main difference between a JSON resource and a JSON collection is that a resource extends the JsonResource class and expects a single resource to be passed when being instantiated while a collection extends the ResourceCollection class and expects a collection as the argument when being instantiated. Back to the metadata bit. But we have a problem, each song inside the data attribute is not formatted to the specification we defined earlier inside the SongResource and instead has all attributes.

What if one wants to add metadata to a single resource and not a collection? In this project, we only have two models, Album and Song. The current relationship is a one-to-many relationship, meaning an album has many songs and a song belongs to an album. If we want to be more specific in terms of what album attributes should be present in the response, we can create an AlbumResource similar to what we did with songs.

Once the resource class has been created, we then specify the attributes we want to be included in the response. This can be avoided by eager loading relationships. Every now and then, we might have a conditional determining the type of response that should be returned. One approach we could take is introducing if statements inside our toArray method. Just to mention a few, we have the whenwhenLoaded and mergeWhen methods.

Instead of having an if statement that dictates whether some attribute and its value should be part of the response, we can use the mergeWhen method which takes in the condition to evaluate as the first argument and an array containing key-value pair that is meant to be part of the response if the condition evaluates to true:.

This looks cleaner and more elegant instead of having if statements wrapping the entire return block. Notice the --unit flag when generating the test: this will tell Laravel that this should be a unit test. And since we already know the song attributes that should be part of the response, we can now make our assertion:. You can list as many attributes as you would like. If you want to make sure your model relationships are preserved even after converting models to resources, you can use:.

Like so:.
