A simple client for JSON APIs using Guzzle and the Symfony Serializer.

To implement a API client, you can extend AbstractApiClient and write your methods, using the Guzzle Http Client to transmit.

class MyClient extends AbstractApiClient {
    
    
    /**
     * @throws TransferException
     */
    public function send(Model $model):void
    {
        // The data will automatically be 
        // serialized to JSON. 
        $this->http->post('model', [
            'data' => $model
        ]);
    }
    
    
    /**
     * @param int $id
     * @throws TransferException
     * @returns Model 
     */
    public function get(int $id):Model
    {
        return $this->http->get('model/'.$id, [
            'deserialize_to' => Model::class
        ]);
    }


}

All functionality is implemented as middleware, the AbstractApiClient just configures the Guzzle HandlerStack for you.

Provided middleware

Serialization

See DeserializeResponseMiddleware and SerializeRequestBodyMiddleware.

Server error messages

ServerMessageMiddleware provides support for JSON error messages.

Response expectations

If you want to make sure that a response has a specific header, content type or other feature, use ResponseExpectationMiddleware.

Logging

There is also middleware to log all HTTP requests (and corresponding response or exception), see HttpLoggingMiddleware

An adapter for Psr\Log\LoggerInterface is available.

This middleware is not added by default because the order is important: The HttpLoggingMiddleware must be added last.
