Swoole是一種基於PHP開發的高效能網路通訊框架,它可以幫助我們更快速、有效率地進行socket編程,從而實現非同步、平行、分散式等應用場景的需求。 Swoole框架的應用各種場景中越來越廣泛,特別是在介面開發中的應用越來越多。
本文將介紹如何利用Swoole框架封裝接口,讓介面的開發與使用更快速、更有效率。
一、Swoole框架基礎介紹
Swoole是一種基於PHP進行網路通訊的框架,它透過C 擴充實現了非同步I/O和並行處理等基礎功能,提供了一系列高效能、靈活、易用的函數和類,可快速實現服務導向的網路程式設計。 Swoole的核心功能如下:
二、Swoole框架介面封裝範例
下面我們透過一個簡單的範例,介紹如何利用Swoole框架封裝介面:
<?php use \Swoole\Coroutine\Http\Server as HttpServer; use \Swoole\Http\Request; use \Swoole\Http\Response; class BaseApiServer { protected $httpServer; public function __construct($host, $port) { $this->httpServer = new HttpServer($host, $port, false); $this->httpServer->set([ 'worker_num' => swoole_cpu_num(), 'max_request' => 50000, 'dispatch_mode' => 3, 'open_http2_protocol' => true, ]); } public function start() { $this->httpServer->on('Request', [$this, 'onRequest']); $this->httpServer->start(); } protected function jsonResponse(Response $response, $status = 200, $data = [], $msg = 'ok') { $result = [ 'code' => $status, 'message' => $msg, 'data' => $data ]; $response->header('Content-Type', 'application/json;charset=utf-8'); $response->end(json_encode($result, JSON_UNESCAPED_UNICODE)); } protected function exceptionHandler(Response $response, $exception) { $this->jsonResponse($response, 500, [], $exception->getMessage()); } protected function retry(\Closure $callback, $retryCount = 3, $interval = 300, $default = []) { $current = 0; while ($current < $retryCount) { try { $result = $callback(); if ($result) { return $result; } } catch (\Throwable $throwable) { //ignore } $current++; if ($current < $retryCount) { usleep($interval * 1000); } } return $default; } public function onRequest(Request $request, Response $response) { try { $this->handle($request, $response); } catch (\Throwable $throwable) { $this->exceptionHandler($response, $throwable); } } protected function onNotFound(Request $request, Response $response) { $this->jsonResponse($response, 404); } protected function handle(Request $request, Response $response) { $url = $request->server['request_uri']; $method = $request->server['request_method']; if (method_exists($this, $method . ucfirst($url))) { $this->{$method . ucfirst($url)}($request, $response); } else { $this->onNotFound($request, $response); } } }
<?php use \Swoole\Http\Request; use \Swoole\Http\Response; class UserApiServer extends BaseApiServer { public function getUser(Request $request, Response $response) { $userId = $request->get['userId']; $result = $this->retry(function () use ($userId) { // TODO: 从数据库或缓存中获取用户信息 return [ 'id' => $userId, 'name' => 'demo', // ... ]; }); $this->jsonResponse($response, 200, $result); } }
<?php require __DIR__ . '/vendor/autoload.php'; $server = new UserApiServer('0.0.0.0', 9501); $server->start();
http://0.0.0.0:9501/getUser?userId=1來取得對應的使用者資訊。
三、總結以上是利用Swoole框架封裝介面的一個基礎範例,總結一下:以上是swoole怎樣封裝寫入接口的詳細內容。更多資訊請關注PHP中文網其他相關文章!
