中進(jìn)行配置。找到以下代碼段:
return [ // ... 'ext' => [ // ... ], // ... ];
在ext
數(shù)組中加入thinkswooleSwoole
即可,如下所示:
return [ // ... 'ext' => [ thinkswooleSwoole::class, ], // ... ];
- 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); } }
- 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' => [ // ... ], // ... ];
在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', ], ], // ... ];
- 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'); } }
- 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 thinkacadeRpc; 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()); } } }
- 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
和/transaction/rollback
