TP6 Interoperability between RPC services and Web services built by Think-Swoole

With the development of the Internet, more and more application requirements require the construction of distributed systems. When building a distributed system, RPC (Remote Procedure Call) is an important communication mechanism, which can enable remote calls between different service nodes.

In development, we often use ThinkPHP as the basic framework of the application, and Swoole is a very excellent PHP asynchronous and concurrent framework. Combining these two frameworks, high-performance RPC services can be well built.

This article will introduce how to use TP6 Think-Swoole to build RPC services and achieve interoperability with Web services.

In the first step, we first need to install ThinkPHP6 and Swoole. Can be installed via Composer. Enter the following command in the command line:

composer create-project topthink/think
composer require swoole/swoole

After the installation is complete, we need to configure ThinkPHP6 and Swoole. In the root directory of the project, find the .env file and edit the configuration information:

APP_NAMESPACE=app
APP_DEBUG=false

[SERVER]
SERVER_SOFTWARE=swoole-http-server
SERVER_PORT=9501
SERVER_HOST=0.0.0.0

In the above configuration, we specified the server port number as 9501 and the listening address. It is 0.0.0.0 and can be modified according to actual needs.

Next, we need to create an RPC controller. In ThinkPHP6, the controller is located in the controller folder under the app directory. We create a controller named RpcController and add a method named hello to handle RPC requests.

Create a PHP file named RpcController in the app/controller directory and add the following code:

<?php
namespace appcontroller;

class RpcController
{
    public function hello($name)
    {
        return "Hello, " . $name . "!";
    }
}

In the above code, We define a method called hello that takes a $name parameter and returns a string containing the greeting.

Next, we need to add support for the RPC service in the Swoole server script. We need to modify the public/index.php file and add the following code to thinkApp before instantiation:

use SwooleCoroutineScheduler;
use thinkswooleServer;

// 创建一个Swoole服务器实例
$server = new Server('0.0.0.0', '9501');
// 添加对RpcController的支持
$server->set([
    'handle_rpc' => function ($server, $fd, $fromId, $data) {
        $scheduler = new Scheduler;
        $scheduler->add(function () use ($server, $fd, $fromId, $data) {
            $result = app('rpc')->run($data);
            $server->send($fd, $result);
        });
        $scheduler->start();
    },
]);
// 启动服务器
$server->start();

In the above code, we create a swoole hinkServer instance, and then use the set method to add support for the RPC controller. In the above code, we use the handle_rpc method to handle RPC requests and call RpcController## through app('rpc')->run($data) # method and return the result to the client.

At this point, we have completed the construction of the RPC service. Let's test it below.

First, run the following command in the command line to start the Swoole server:

php think swoole:start

Then, open a new terminal and use the curl command to send an RPC request:

curl 127.0.0.1:9501 -d '{"jsonrpc": "2.0", "method": "hello", "params": ["Alice"], "id": 1}'

If everything goes well, you will see the returned result in the terminal:

{"jsonrpc":"2.0","result":"Hello, Alice!","id":1}

At this point, we have successfully built an RPC service based on TP6 Think-Swoole and achieved interoperability with Web services.

In this article, we successfully built an RPC-based service and achieved interoperability with Web services by using ThinkPHP6 and Swoole. In this way, our applications can be made more flexible and efficient. I hope this article can be helpful to everyone.
