# RestClient

RestClient is [an interface](src/RestClientInterface.php) representing the main entry point for performing REST requests.

RestClient is a handy tool that adds a list of extra features to a Psr/HttpClient (at the same time it is not intended to
replace Psr/HttpClient):
1. Serializer/Deserialize request/response body.
2. Intercept request (allows to modify request before sending or process a response object).
3. Retry strategy.

## Install

```shell
composer require paveldanilin/rest-client
```

## Quick Examples

### Create a new REST client

For simplicity, we are using a Guzzle HTTP client, but you are free to use any PSR-18 compliant HTTP client.

```php
// PSR-18 HTTP client
$httpClient = new GuzzleHttp\Client([
'base_uri' => 'https://animechan.vercel.app',
]);

// Serializer
$serializer = new \RestClient\Serialization\Symfony\JsonSymfonySerializer();

$restClient = new \RestClient\RestClient($httpClient, $serializer);
```

### Define an application response model
```php
class AnimeQuote
{
private string $anime = '';
private string $character = '';
private string $quote = '';

public function getAnime(): string
{
return $this->anime;
}

public function setAnime(string $anime): void
{
$this->anime = $anime;
}

public function getCharacter(): string
{
return $this->character;
}

public function setCharacter(string $character): void
{
$this->character = $character;
}

public function getQuote(): string
{
return $this->quote;
}

public function setQuote(string $quote): void
{
$this->quote = $quote;
}
}
```

### Get an object

Take a look at [the example](example/anime_quote.php).

```php
/** @var AnimeQuote|null $quote */
$quote = $restClient->getForObject('/api/random', AnimeQuote::class);

print "------------------------------------------\n";
print 'Anime: ' . $quote->getAnime() . "\n";
print 'Character: ' . $quote->getCharacter() . "\n";
print 'Quote: ' . $quote->getQuote() . "\n";
print "------------------------------------------\n";
```

### Get a list of objects

Take a look at [the example](example/JsonPlaceholder/print_blog_posts.php).

```php
/** @var array $models */
$models = $restClient->getForObject('/api/models', \RestClient\Helpers\asList(ApiModel::class));
```

### Intercept request

Use case of interceptor:
- Request header modification
- Request and response logging
- Request denial based on certain request parameters
- Changing the request URL address

Out of the box you can use following interceptors:
* [Log request](src/Interceptor/LogRequestInterceptor.php)
* [Retry](src/Interceptor/RetryInterceptor.php)
* [Add header](src/Interceptor/AddHeaderInterceptor.php)
* [Callable](src/Interceptor/CallableInterceptor.php)

Did not find a right interceptor? Do not get upset!
It's easy to create a new one, just implement the following interface:

```php
interface RequestInterceptorInterface
{
/**
* @throws ClientExceptionInterface
*/
public function intercept(RequestInterface $request, ContextInterface $context, RequestExecutionInterface $execution): ResponseInterface;
}
```

Set interceptors
```php
$restClient->setInterceptors([
new \RestClient\Interceptor\RetryInterceptor(), // <- Retry request in case of [429] or [503] response status
new \RestClient\Interceptor\RequestIdInterceptor(), // <- Add Request-Id header (uuid v4)
new \RestClient\Interceptor\LogRequestInterceptor($logger), // <- Log before/after and exception
]);
```
