# Jet, by Hyperf
Jet is a unification model RPC Client, built-in JSONRPC protocol, available to running in ALL PHP environments, including PHP-FPM and Swoole/Hyperf environments.
> Also will built-in gRPC and Tars protocols in future.
# Installation
```bash
composer require hyperf/jet
```
# Quickstart
## Register protocol
> Register the protocol is not necessary, but you could manage the protocols more easily by using ProtocolManager.
You cloud register any protocol by `Hyperf\Jet\ProtocolManager`, per protocol basically including Transporter, Packer, DataFormatter and PathGenerator, you could register a JSONRPC protocol like below:
```php
<?php
use Hyperf\Jet\DataFormatter\DataFormatter;
use Hyperf\Jet\Packer\JsonEofPacker;
use Hyperf\Jet\PathGenerator\PathGenerator;
use Hyperf\Jet\ProtocolManager;
use Hyperf\Jet\Transporter\StreamSocketTransporter;
ProtocolManager::register($protocol = 'jsonrpc', [
ProtocolManager::TRANSPORTER => new StreamSocketTransporter(),
ProtocolManager::PACKER => new JsonEofPacker(),
ProtocolManager::PATH_GENERATOR => new PathGenerator(),
ProtocolManager::DATA_FORMATTER => new DataFormatter(),
]);
```
## Register service
> > Register the service is not necessary, but you could manage the services more easily by using ServiceManager.
After you registered a protocol to `Hyperf\Jet\ProtocolManager`, you could bind the protocol with any services by `Hyperf\Jet\ServiceManager`, like below:
```php
<?php
use Hyperf\Jet\ServiceManager;
// Bind CalculatorService with jsonrpc protocol, and set the static nodes info.
ServiceManager::register($service = 'CalculatorService', $protocol = 'jsonrpc', [
ServiceManager::NODES => [
[$host = '127.0.0.1', $port = 9503],
],
]);
```
## Call RPC method
### Call by ClientFactory
After you registered the protocol and service, you could get your service client via `Hyperf/Jet/ClientFactory`, like below:
```php
<?php
use Hyperf\Jet\ClientFactory;
$clientFactory = new ClientFactory();
$client = $clientFactory->create($service = 'CalculatorService', $protocol = 'jsonrpc');
```
When you have the client object, you could call any remote methods via the object, like below:
```php
// Call the remote method `add` with arguments `1` and `2`.
// The $result is the result of the remote method.
$result = $client->add(1, 2);
```
If you call a not exist remote method, the client will throw an `Hyperf\Jet\Exception\ServerException` exception.
### Call by custom client
You could also create a custom client class which extends `Hyperf\Jet\AbstractClient`, to call the remote methods via the client object.
For example, you want to define a RPC client for `CalculatorService` with `jsonrpc` protocol, you could create a `CalculatorService` class firstly, like below:
```php
<?php
use Hyperf\Jet\AbstractClient;
use Hyperf\Jet\Packer\JsonEofPacker;
use Hyperf\Jet\Transporter\StreamSocketTransporter;
use Hyperf\Rpc\Contract\DataFormatterInterface;
use Hyperf\Rpc\Contract\PackerInterface;
use Hyperf\Rpc\Contract\PathGeneratorInterface;
use Hyperf\Rpc\Contract\TransporterInterface;
/**
* @method int add(int $a, int $b);
*/
class CalculatorService extends AbstractClient
{
// Define `CalculatorService` as the default value of $service.
public function __construct(
string $service = 'CalculatorService',
TransporterInterface $transporter = null,
PackerInterface $packer = null,
?DataFormatterInterface $dataFormatter = null,
?PathGeneratorInterface $pathGenerator = null
) {
// Specific the transporter here, you could also retrieve the transporter from ProtocolManager or passing by constructor.
$transporter = new StreamSocketTransporter('127.0.0.1', 9503);
// Specific the packer here, you could also retrieve the packer from ProtocolManager or passing by constructor.
$packer = new JsonEofPacker();
parent::__construct($service, $transporter, $packer, $dataFormatter, $pathGenerator);
}
}
```
Now, you could use this class to call the remote method directly, like below:
```php
// Call the remote method `add` with arguments `1` and `2`.
// The $result is the result of the remote method.
$client = new CalculatorService();
$result = $client->add(1, 2);
```

# Jet
Jet 是一個統一模型的 RPC 客户端,內置 JSONRPC 協議的適配,該組件可適用於所有的 PHP 環境,包括 PHP-FPM 和 Swoole 或 Hyperf。在 Hyperf 環境下,目前仍建議直接使用 `hyperf/json-rpc` 組件來作為客户端使用)
> 未來還會內置 gRPC 和 Tars 協議。
# 安裝
```bash
composer require hyperf/jet
```
# 快速開始
## 註冊協議
> 註冊協議不是必須的一個步驟,但您可以通過 ProtocolManager 管理所有的協議。
您可以通過 `Hyperf\Jet\ProtocolManager` 類來註冊管理任意的協議,每個協議會包含 Transporter, Packer, DataFormatter and PathGenerator 幾個基本的組件,您可以註冊一個 JSONRPC 協議,如下:
```php
<?php
use Hyperf\Jet\DataFormatter\DataFormatter;
use Hyperf\Jet\Packer\JsonEofPacker;
use Hyperf\Jet\PathGenerator\PathGenerator;
use Hyperf\Jet\ProtocolManager;
use Hyperf\Jet\Transporter\StreamSocketTransporter;
ProtocolManager::register($protocol = 'jsonrpc', [
ProtocolManager::TRANSPORTER => new StreamSocketTransporter(),
ProtocolManager::PACKER => new JsonEofPacker(),
ProtocolManager::PATH_GENERATOR => new PathGenerator(),
ProtocolManager::DATA_FORMATTER => new DataFormatter(),
]);
```
## 註冊服務
> 註冊服務不是必須的一個步驟,但您可以通過 ServiceManager 管理所有的服務。
在您往 `Hyperf\Jet\ProtocolManager` 註冊了一個協議之後,您可以通過 `Hyperf\Jet\ServiceManager` 將協議綁定到任意的服務上,如下:
```php
<?php
use Hyperf\Jet\ServiceManager;
// 綁定 CalculatorService 與 jsonrpc 協議,同時設定靜態的節點信息
ServiceManager::register($service = 'CalculatorService', $protocol = 'jsonrpc', [
ServiceManager::NODES => [
[$host = '127.0.0.1', $port = 9503],
],
]);
```
## 調用 RPC 方法
### 通過 ClientFactory 調用
在您註冊完協議與服務之後,您可以通過 `Hyperf/Jet/ClientFactory` 來獲得您的服務的客户端,如下所示:
```php
<?php
use Hyperf\Jet\ClientFactory;
$clientFactory = new ClientFactory();
$client = $clientFactory->create($service = 'CalculatorService', $protocol = 'jsonrpc');
```
當您擁有 client 對象後,您可以通過該對象調用任意的遠程方法,如下:
```php
// 調用遠程方法 `add` 並帶上參數 `1``2`
// $result 即為遠程方法的返回值
$result = $client->add(1, 2);
```
當您調用一個不存在的遠程方法時,客户端會拋出一個 `Hyperf\Jet\Exception\ServerException` 異常。
### 通過自定義客户端調用
您可以創建一個 `Hyperf\Jet\AbstractClient` 的子類作為自定義的客户端類,來完成遠程方法的調用,比如,您希望定義一個 `CalculatorService` 服務的 `jsonrpc` 協議的客户端類,您可以先定義一個 `CalculatorService` 類,如下所示:
```php
<?php
use Hyperf\Jet\AbstractClient;
use Hyperf\Jet\Packer\JsonEofPacker;
use Hyperf\Jet\Transporter\StreamSocketTransporter;
use Hyperf\Rpc\Contract\DataFormatterInterface;
use Hyperf\Rpc\Contract\PackerInterface;
use Hyperf\Rpc\Contract\PathGeneratorInterface;
use Hyperf\Rpc\Contract\TransporterInterface;
/**
* @method int add(int $a, int $b);
*/
class CalculatorService extends AbstractClient
{
// 定義 `CalculatorService` 作為 $service 參數的默認值
public function __construct(
string $service = 'CalculatorService',
TransporterInterface $transporter = null,
PackerInterface $packer = null,
?DataFormatterInterface $dataFormatter = null,
?PathGeneratorInterface $pathGenerator = null
) {
// 這裏指定 transporter您仍然可以通過 ProtocolManager 來獲得 transporter 或從構造函數傳遞
$transporter = new StreamSocketTransporter('127.0.0.1', 9503);
// 這裏指定 packer您仍然可以通過 ProtocolManager 來獲得 packer 或從構造函數傳遞
$packer = new JsonEofPacker();
parent::__construct($service, $transporter, $packer, $dataFormatter, $pathGenerator);
}
}
```
現在,您可以通過該類來直接調用遠程方法了,如下所示:
```php
// 調用遠程方法 `add` 並帶上參數 `1``2`
// $result 即為遠程方法的返回值
$client = new CalculatorService();
$result = $client->add(1, 2);
```

[$host = '127.0.0.1', $port = 9503],
],
]);
```
## 呼叫 RPC 方法
### 通過 ClientFactory 呼叫
在您註冊完協議與服務之後,您可以通過 `Hyperf/Jet/ClientFactory` 來獲得您的服務的客戶端,如下所示:
```php
<?php
use Hyperf\Jet\ClientFactory;
$clientFactory = new ClientFactory();
$client = $clientFactory->create($service = 'CalculatorService', $protocol = 'jsonrpc');
```
當您擁有 client 物件後,您可以通過該物件呼叫任意的遠端方法,如下:
```php
// 呼叫遠端方法 `add` 並帶上引數 `1``2`
// $result 即為遠端方法的返回值
$result = $client->add(1, 2);
```
當您呼叫一個不存在的遠端方法時,客戶端會丟擲一個 `Hyperf\Jet\Exception\ServerException` 異常。
### 通過自定義客戶端呼叫
您可以建立一個 `Hyperf\Jet\AbstractClient` 的子類作為自定義的客戶端類,來完成遠端方法的呼叫,比如,您希望定義一個 `CalculatorService` 服務的 `jsonrpc` 協議的客戶端類,您可以先定義一個 `CalculatorService` 類,如下所示:

use Hyperf\Jet\Packer\JsonEofPacker;
use Hyperf\Jet\Transporter\StreamSocketTransporter;
use Hyperf\Rpc\Contract\DataFormatterInterface;
use Hyperf\Rpc\Contract\PackerInterface;
use Hyperf\Rpc\Contract\PathGeneratorInterface;
use Hyperf\Rpc\Contract\TransporterInterface;
/**
* @method int add(int $a, int $b);
*/
class CalculatorService extends AbstractClient
{
// 定義 `CalculatorService` 作為 $service 引數的預設值
public function __construct(
string $service = 'CalculatorService',
TransporterInterface $transporter = null,
PackerInterface $packer = null,
?DataFormatterInterface $dataFormatter = null,
?PathGeneratorInterface $pathGenerator = null
) {
// 這裡指定 transporter您仍然可以通過 ProtocolManager 來獲得 transporter 或從建構函式傳遞
$transporter = new StreamSocketTransporter('127.0.0.1', 9503);
// 這裡指定 packer您仍然可以通過 ProtocolManager 來獲得 packer 或從建構函式傳遞
$packer = new JsonEofPacker();
parent::__construct($service, $transporter, $packer, $dataFormatter, $pathGenerator);
}
