> Мы, участники Laminas, родились и живем в разных странах. У многих из нас есть друзья, родственники и коллеги как в России, так и в Украине. Некоторые из нас родились в России. Некоторые из нас живут в России. У некоторых бабушки и дедушки сражались с фашистами во Второй мировой войне. Здесь никто не поддерживает фашизм.

> У одного из нас есть украинская родственница, которая спаслась из дома вместе с сыном. Поезд задержался из-за бомбежки на дороге впереди. У нас есть друзья, которые прячутся в бомбоубежищах. Мы с тревогой ждем весточки от них после воздушных налетов, которые беспорядочно наносят удары и попадают по больницам, школам, детским садам и домам. Мы не берем это из каких-либо СМИ. Мы наблюдаем это напрямую.

Introduction
------------

[](#introduction)

This module provides data structures and rendering for the API-Problem format.

- [Problem Details for HTTP APIs](https://tools.ietf.org/html/rfc7807), used for reporting API problems.

Requirements
------------

[](#requirements)

Please see the [composer.json](composer.json) file.

Installation
------------

[](#installation)

Run the following `composer` command:

```
$ composer require laminas-api-tools/api-tools-api-problem
```

Alternately, manually add the following to your `composer.json`, in the `require` section:

```
"require": {
    "laminas-api-tools/api-tools-api-problem": "^1.2"
}
```

And then run `composer update` to ensure the module is installed.

Finally, add the module name to your project's `config/application.config.php` under the `modules`key:

Configuration
=============

[](#configuration)

### User Configuration

[](#user-configuration)

The top-level configuration key for user configuration of this module is `api-tools-api-problem`.

#### Key: accept\_filters

[](#key-accept_filters)

An array of `Accept` header media types that, when matched, will result in the [ApiProblemListener](#laminasapiproblemlistenerapiproblemlistener) handling an `MvcEvent::EVENT_RENDER_ERROR` event.

#### Key: render\_error\_controllers

[](#key-render_error_controllers)

An array of controller service names that, if matched as the `controller` parameter in the MVC `RouteMatch`, will cause the [ApiProblemListener](#laminasapiproblemlistenerapiproblemlistener) to handle `MvcEvent::EVENT_RENDER_ERROR` events.

### System Configuration

[](#system-configuration)

The following configuration is provided in `config/module.config.php` to enable the module to function:

```
'service_manager' => [
    'aliases'   => [
        'Laminas\ApiTools\ApiProblem\ApiProblemListener'  => 'Laminas\ApiTools\ApiProblem\Listener\ApiProblemListener',
        'Laminas\ApiTools\ApiProblem\RenderErrorListener' => 'Laminas\ApiTools\ApiProblem\Listener\RenderErrorListener',
        'Laminas\ApiTools\ApiProblem\ApiProblemRenderer'  => 'Laminas\ApiTools\ApiProblem\View\ApiProblemRenderer',
        'Laminas\ApiTools\ApiProblem\ApiProblemStrategy'  => 'Laminas\ApiTools\ApiProblem\View\ApiProblemStrategy',
    ],
    'factories' => [
        'Laminas\ApiTools\ApiProblem\Listener\ApiProblemListener'             => 'Laminas\ApiTools\ApiProblem\Factory\ApiProblemListenerFactory',
        'Laminas\ApiTools\ApiProblem\Listener\RenderErrorListener'            => 'Laminas\ApiTools\ApiProblem\Factory\RenderErrorListenerFactory',
        'Laminas\ApiTools\ApiProblem\Listener\SendApiProblemResponseListener' => 'Laminas\ApiTools\ApiProblem\Factory\SendApiProblemResponseListenerFactory',
        'Laminas\ApiTools\ApiProblem\View\ApiProblemRenderer'                 => 'Laminas\ApiTools\ApiProblem\Factory\ApiProblemRendererFactory',
        'Laminas\ApiTools\ApiProblem\View\ApiProblemStrategy'                 => 'Laminas\ApiTools\ApiProblem\Factory\ApiProblemStrategyFactory',
    ],
],
'view_manager' => [
    // Enable this in your application configuration in order to get full
    // exception stack traces in your API-Problem responses.
    'display_exceptions' => false,
],
```

Laminas Events
--------------

[](#laminas-events)

### Listeners

[](#listeners)

#### Laminas\\ApiTools\\ApiProblem\\Listener\\ApiProblemListener

[](#laminasapitoolsapiproblemlistenerapiproblemlistener)

The `ApiProblemListener` attaches to three events in the MVC lifecycle:

- `MvcEvent::EVENT_DISPATCH` as a *shared* listener on `Laminas\Stdlib\DispatchableInterface` with a priority of `100`.
- `MvcEvent::EVENT_DISPATCH_ERROR` with a priority of `100`.
- `MvcEvent::EVENT_RENDER` with a priority of `1000`.

If the current `Accept` media type does not match the configured API-Problem media types (by default, these are `application/json` and `application/*+json`), then this listener returns without taking any action.

When this listener does take action, the purposes are threefold:

- Before dispatching, the `render_error_controllers` configuration value is consulted to determine if the `Laminas\ApiTools\ApiProblem\Listener\RenderErrorListener` should be attached; see [RenderErrorListener](#rendererrorlistener) for more information.
- After dispatching, detects the type of response from the controller; if it is already an `ApiProblem` model, it continues without doing anything. If an exception was thrown during dispatch, it converts the response to an API-Problem response with some information from the exception.
- If a dispatch error occurred, and the `Accept` type is in the set defined for API-Problems, it attempts to cast the dispatch exception into an API-Problem response.

#### Laminas\\ApiTools\\ApiProblem\\Listener\\RenderErrorListener

[](#laminasapitoolsapiproblemlistenerrendererrorlistener)

This listener is attached to `MvcEvent::EVENT_RENDER_ERROR` at priority `100`. This listener is conditionally attached by `Laminas\ApiTools\ApiProblem\Listener\ApiProblemListener` for controllers that require API Problem responses. With a priority of `100`, this ensures that this listener runs before the default Laminas listener on this event. In cases when it does run, it will cast an exception into an API-problem response.

#### `Laminas\ApiTools\ApiProblem\Listener\SendApiProblemResponseListener`

[](#laminasapitoolsapiproblemlistenersendapiproblemresponselistener)

This listener is attached to `SendResponseEvent::EVENT_SEND_RESPONSE` at priority `-500`. The primary purpose of this listener is, on detection of an API-Problem response, to send appropriate headers and the problem details as the content body. If the `view_manager`'s `display_exceptions`setting is enabled, the listener will determine if the API-Problem represents an application exception, and, if so, inject the exception trace as part of the serialized response.

Laminas Services
----------------

[](#laminas-services)

### Event Services

[](#event-services)

- `Laminas\ApiTools\ApiProblem\Listener\ApiProblemListener`
- `Laminas\ApiTools\ApiProblem\Listener\RenderErrorListener`
- `Laminas\ApiTools\ApiProblem\Listener\SendApiProblemResponseListener`

### View Services

[](#view-services)

#### Laminas\\ApiTools\\ApiProblem\\View\\ApiProblemRenderer

[](#laminasapitoolsapiproblemviewapiproblemrenderer)

This service extends the `JsonRenderer` service from the Laminas MVC layer. Its primary responsibility is to decorate JSON rendering with the ability to optionally output stack traces.

#### Laminas\\ApiTools\\ApiProblem\\View\\ApiProblemStrategy

[](#laminasapitoolsapiproblemviewapiproblemstrategy)

This service is a view strategy that detects a `Laminas\ApiTools\ApiProblem\View\ApiProblemModel`; when detected, it selects the [ApiProblemRender](#laminasapiproblemviewapiproblemrenderer), and injects the response with a `Content-Type` header that contains the `application/problem+json` media type. This is similar in nature to Laminas's `JsonStrategy`.

### Models

[](#models)

#### Laminas\\ApiTools\\ApiProblem\\ApiProblem

[](#laminasapitoolsapiproblemapiproblem)

An instance of `Laminas\ApiTools\ApiProblem\ApiProblem` serves the purpose of modeling the kind of problem that is encountered. An instance of `ApiProblem` is typically wrapped in an [ApiProblemResponse](#laminasapiproblemapiproblemresponse). Most information can be passed into the constructor:

```
class ApiProblem
{
    public function __construct(
        $status,
        $detail,
        $type = null,
        $title = null,
        array $additional = []
    ) {
        /* ... */
    }
}
```

For example:

```
new ApiProblem(404, 'Entity not found');

// or

new ApiProblem(424, $exceptionInstance);
```

#### `Laminas\ApiTools\ApiProblem\ApiProblemResponse`

[](#laminasapitoolsapiproblemapiproblemresponse)

An instance of `Laminas\ApiTools\ApiProblem\ApiProblemResponse` can be returned from any controller service or Laminas MVC event in order to short-circuit the MVC lifecycle and immediately return a response. When it is, the response will be converted to the proper JSON structure for an API-Problem, and the `Content-Type` header will be set to the `application/problem+json` media type.

For example:

```
use Laminas\Mvc\Controller\AbstractActionController;
use Laminas\ApiTools\ApiProblem\ApiProblem;
use Laminas\ApiTools\ApiProblem\ApiProblemResponse;

class MyController extends AbstractActionController
{
    /* ... */
    public function fetch($id)
    {
        $entity = $this->model->fetch($id);
        if (! $entity) {
            return new ApiProblemResponse(new ApiProblem(404, 'Entity not found'));
        }
        return $entity;
    }
}
```
