return [

    'ext' => [
        // ...
    ],
    // ...
];

ext數(shù)組中加入thinkswooleSwoole即可,如下所示:

return [
    // ...
    'ext' => [
        thinkswooleSwoole::class,
    ],
    // ...
];
  1. 創(chuàng)建RPC服務(wù)

在ThinkPHP 6中,我們可以使用中間件來實(shí)現(xiàn)RPC服務(wù)。創(chuàng)建一個新的中間件類,在app/middleware目錄下創(chuàng)建一個名為RpcMiddleware.php的文件,并在其中編寫以下代碼:

<?php

namespace appmiddleware;

use SwooleCoroutine;
use thinkswoolepcserverResponse;
use thinkswoolepcserverReceiveContext;
use thinkswooleRpc;

class RpcMiddleware
{
    public function handle(ReceiveContext $context, Closure $next)
    {
        // 執(zhí)行遠(yuǎn)程過程調(diào)用
        $response = new Response();
        $rpc = new Rpc();
        $rpc->dispatch($context->getRaw(), $response);
        // 獲取執(zhí)行結(jié)果
        $result = $response->getMessage();

        if ($response->getCode() === Rpc::RESULT_CODE_SUCCESS) {
            // 執(zhí)行成功,將結(jié)果返回給客戶端
            $context->reply($result);
        } else {
            // 出現(xiàn)錯誤,設(shè)置錯誤代碼和消息
            $context->setCode($response->getCode());
            $context->setMessage($response->getMessage());
        }

        return $next($context);
    }
}
  1. 配置RPC服務(wù)

在ThinkPHP 6中,我們可以通過配置文件來定義中間件。打開config/middleware.php文件,并添加要使用的中間件類,如下所示:

return [
    // ...
    // rpc服務(wù)中間件
    appmiddlewareRpcMiddleware::class,
];

然后,我們需要在config/swoole.php文件中進(jìn)行一些額外的配置。找到以下代碼段:

return [
    // ...
    'rpc' => [
        // ...
    ],
    // ...
];

rpc數(shù)組中添加以下代碼:

return [
    // ...
    'rpc' => [
        'server' => [
            // 綁定服務(wù)地址和端口
            'host' => '127.0.0.1',
            'port' => 9502,
        ],
        'services' => [
            // 注冊服務(wù)
            'AppRpcServicesTransactionService',
        ],
    ],
    // ...
];
  1. 創(chuàng)建事務(wù)服務(wù)

我們將創(chuàng)建一個名為TransactionService的服務(wù)類,用于處理分布式事務(wù)。在app/rpc/services目錄下創(chuàng)建一個名為TransactionService.php的文件,并在其中編寫以下代碼:

<?php

namespace apppcservices;

use thinkswoolepcRequest;
use thinkswoolepcResponse;

class TransactionService
{
    public function beginTransaction(Request $request, Response $response)
    {
        // 執(zhí)行事務(wù)開始操作
        // ...

        $response->setCode(Response::CODE_SUCCESS);
        $response->setMessage('事務(wù)開始成功');
    }

    public function commit(Request $request, Response $response)
    {
        // 執(zhí)行事務(wù)提交操作
        // ...

        $response->setCode(Response::CODE_SUCCESS);
        $response->setMessage('事務(wù)提交成功');
    }

    public function rollback(Request $request, Response $response)
    {
        // 執(zhí)行事務(wù)回滾操作
        // ...

        $response->setCode(Response::CODE_SUCCESS);
        $response->setMessage('事務(wù)回滾成功');
    }
}
  1. 調(diào)用RPC服務(wù)

最后,我們將在主應(yīng)用中調(diào)用RPC服務(wù)來執(zhí)行分布式事務(wù)處理。創(chuàng)建一個新的控制器類,在app/controller目錄下創(chuàng)建一個名為TransactionController.php的文件,并在其中編寫以下代碼:

<?php

namespace appcontroller;

use thinkacadeRpc;
use thinkswoolepcRequest;

class TransactionController
{
    public function beginTransaction()
    {
        // 創(chuàng)建RPC請求
        $request = new Request();
        $request->setService('AppRpcServicesTransactionService');
        $request->setMethod('beginTransaction');

        // 發(fā)起遠(yuǎn)程調(diào)用
        $result = Rpc::call($request);

        // 處理返回結(jié)果
        if ($result->getCode() === 200) {
            // 操作成功
            return '事務(wù)開始成功';
        } else {
            // 操作失敗
            throw new Exception($result->getMessage(), $result->getCode());
        }
    }

    public function commit()
    {
        // 創(chuàng)建RPC請求
        $request = new Request();
        $request->setService('AppRpcServicesTransactionService');
        $request->setMethod('commit');

        // 發(fā)起遠(yuǎn)程調(diào)用
        $result = Rpc::call($request);

        // 處理返回結(jié)果
        if ($result->getCode() === 200) {
            // 操作成功
            return '事務(wù)提交成功';
        } else {
            // 操作失敗
            throw new Exception($result->getMessage(), $result->getCode());
        }
    }

    public function rollback()
    {
        // 創(chuàng)建RPC請求
        $request = new Request();
        $request->setService('AppRpcServicesTransactionService');
        $request->setMethod('rollback');

        // 發(fā)起遠(yuǎn)程調(diào)用
        $result = Rpc::call($request);

        // 處理返回結(jié)果
        if ($result->getCode() === 200) {
            // 操作成功
            return '事務(wù)回滾成功';
        } else {
            // 操作失敗
            throw new Exception($result->getMessage(), $result->getCode());
        }
    }
}
  1. 測試RPC服務(wù)

現(xiàn)在我們可以使用瀏覽器或其他HTTP客戶端測試我們的RPC服務(wù)了。在瀏覽器中訪問/transaction/beginTransaction,/transaction/commit/transaction/rollbackrrreee
