How to use the Hyperf framework for distributed service calls
Introduction:
With the development of business, the size and complexity of applications are also growing rapidly. In this case, in order to improve the scalability and scalability of the business, distributed systems are becoming more and more important. Service invocation in distributed systems has also become complex, requiring a reliable framework to simplify development and management.
Hyperf is a high-performance framework based on Swoole extension, focusing on long links and coroutines, providing a large number of components and functions. In this article, we will introduce how to use the Hyperf framework to make distributed service calls.
1. Preparation
First, we need to install the Hyperf framework locally. Hyperf can be quickly installed through the following command:
composer create-project hyperf/hyperf-skeleton
After the installation is complete, some basic configuration of the Hyperf framework is required. You can edit the .env
file to configure database connection, Redis and other related information.
2. Create a service provider
Create a service in the app/Provider
directory Provider class, named RemoteServiceProvider
. This class will define a remote service method.
<?php declare(strict_types=1); namespace AppProvider; use HyperfRpcClientAbstractServiceClient; class RemoteServiceProvider extends AbstractServiceClient { protected $serviceName = 'ServiceName'; protected $protocol = 'jsonrpc-http'; public function remoteMethod(array $params) { return $this->__request(__FUNCTION__, compact('params')); } }
In the above code, RemoteServiceProvider
inherits AbstractServiceClient
and defines a remote method named remoteMethod
.
Edit the config/dependencies.php
file and add the following code:
use AppProviderRemoteServiceProvider; return [ 'dependencies' => [ // ... RemoteServiceProvider::class => RemoteServiceProvider::class, ], ];
3. Create Service consumer
Create a controller class in the app/Controller
directory and name it TestController
. Remote services will be called in this class.
<?php declare(strict_types=1); namespace AppController; use AppProviderRemoteServiceProvider; use HyperfHttpServerAnnotationController; use HyperfHttpServerAnnotationPostMapping; /** * @Controller() */ class TestController { /** * @PostMapping(path="/test") */ public function test(RemoteServiceProvider $service) { $params = ['key' => 'value']; return $service->remoteMethod($params); } }
In the above code, the test
method in the TestController
class injects the RemoteServiceProvider
and calls its remoteMethod
method.
Edit the config/routes.php
file and add the following code:
use AppControllerTestController; $router->addRoute(['POST'], '/test', [TestController::class, 'test']);
4. Start the server and client
Use the following command to start the Hyperf server:
php bin/hyperf.php start
The server will start listening to the specified port and wait for the client ask.
Use the following command to start the Hyperf client:
php bin/hyperf.php start
The client will automatically initiate a request to the server and obtain the response result .
Conclusion:
Through the above steps, we can use the Hyperf framework to make distributed service calls. First, we create a service provider class and define a remote method in it. We then created a controller class, injected the service provider into it and called its methods. Finally, we started the server and client to complete the distributed service call.
The Hyperf framework provides powerful functions and components, making distributed system development simpler and more efficient. By using the Hyperf framework, we can quickly build distributed applications and easily implement microservice architecture.
I hope this article will help you understand how to use the Hyperf framework to make distributed service calls. I wish you success in the development of distributed systems!
