二、實現渲染引擎
三、注冊渲染引擎
四、測試調用寫的模板
五、優化
六、最后補充

一、安裝依賴插件

composer require easyswoole/template:1.1.*
composer require topthink/think-template

相關版本：

        "easyswoole/easyswoole": "3.3.x","easyswoole/orm": "^1.5","easyswoole/template": "1.1.*","topthink/think-template": "^2.0"

二、實現渲染引擎

在 App 目錄下新建 System 目錄存放渲染引擎實現的代碼 ThinkTemplate.php

<?php
namespace App\System;use EasySwoole\Template\RenderInterface;
use think\facade\Template;class ThinkTemplate implements RenderInterface
{// tp模板類對象private $_topThinkTemplate;public function __construct(){$temp_dir = sys_get_temp_dir();$config = ['view_path' => EASYSWOOLE_ROOT . '/App/HttpTemplate/', // 模板存放文件夾根目錄'cache_path' => $temp_dir, // 模板文件緩存目錄'view_suffix' => 'html' // 模板文件后綴];$this->_topThinkTemplate = new \think\Template($config);}public function afterRender(?string $result, string $template, array $data = [], array $options = []){}// 當模板解析出現異常時調用public function onException(\Throwable $throwable): string{$msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();return $msg;}// 渲染邏輯實現public function render(string $template, array $data = [], array $options = []): ?string{foreach ($data as $k => $v) {$this->_topThinkTemplate->assign([$k => $v]);}// Tp 模板渲染函數都是直接輸出 需要打開緩沖區將輸出寫入變量中 然后渲染的結果ob_start();$this->_topThinkTemplate->fetch($template);$content = ob_get_contents();ob_end_clean();return $content;}
}

在這里插入圖片描述

<?php
namespace App\System;use EasySwoole\Template\RenderInterface;
use think\facade\Template;class ThinkTemplate implements RenderInterface
{// tp模板類對象private $_topThinkTemplate;public function __construct(){$temp_dir = sys_get_temp_dir();$config = ['view_path' => EASYSWOOLE_ROOT . '/App/HttpTemplate/', // 模板存放文件夾根目錄'cache_path' => $temp_dir, // 模板文件緩存目錄'view_suffix' => 'html' // 模板文件后綴];$this->_topThinkTemplate = new \think\Template($config);}public function afterRender(?string $result, string $template, array $data = [], array $options = []){}// 當模板解析出現異常時調用// public function onException(\Throwable $throwable): string// {//     $msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();//     return $msg;// }// 渲染邏輯實現// public function render(string $template, array $data = [], array $options = []): ?string// {//     foreach ($data as $k => $v) {//         $this->_topThinkTemplate->assign([$k => $v]);//     }//     // Tp 模板渲染函數都是直接輸出 需要打開緩沖區將輸出寫入變量中 然后渲染的結果//     ob_start();//     $this->_topThinkTemplate->fetch($template);//     $content = ob_get_contents();//     ob_end_clean();//     return $content;// }public function render(string $template, ?array $data = null, ?array $options = null): ?string{// return "your template is {$template} and data is " . json_encode($data);foreach ($data as $k => $v) {$this->_topThinkTemplate->assign([$k => $v]);}// Tp 模板渲染函數都是直接輸出 需要打開緩沖區將輸出寫入變量中 然后渲染的結果ob_start();$this->_topThinkTemplate->fetch($template);$content = ob_get_contents();ob_end_clean();return $content;}public function onException(\Throwable $throwable, $arg): string{// return $throwable->getTraceAsString();$msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();return $msg;}
}

三、注冊渲染引擎

需要對模板引擎進行實例化并且注入到EasySwoole 的視圖中在項目根目錄 EasySwooleEvent.php 中 mainServerCreate 事件函數中進行注入代碼如下

use App\System\ThinkTemplate;
use EasySwoole\Template\Render; use
EasySwoole\Template\RenderInterface;

// 設置Http服務模板類
Render::getInstance()->getConfig()->setRender(new ThinkTemplate());
Render::getInstance()->getConfig()->setTempDir(EASYSWOOLE_TEMP_DIR);
Render::getInstance()->attachServer(ServerManager::getInstance()->getSwooleServer());

四、測試調用寫的模板

在App目錄下創建 HttpTemplate 目錄 PS:之前在 ThinkTemplate.php 文件中設置的路徑

創建文件 /App/HttpTemplate/Admin/Index/index.html 路徑與模塊控制器響應函數相對應你也可以按照自己的喜歡來

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>tao</title>
</head>
<body>
<ul>{foreach $user_list as $key => $val}<li>{$key} => {$val}</li>{/foreach}
</ul>
</body>
</html>

在 App\HttpController\Admin 中調用

use EasySwoole\Template\Render;
public function index(){$user_list = ['1', '2', '3', '4', '5'];$this->response()->write(Render::getInstance()->render('Index/index', ['user_list' => $user_list]));}

五、優化

這樣的模板傳值非常麻煩有木有還必須要放在一個數組中一次性傳給 Render 對象我們可以將操作封裝到基類控制器實現類似于TP框架的操作代碼如下

<?php
/*** 基礎控制器類*/
namespace App\HttpController;use EasySwoole\Template\Render;abstract class Controller extends \EasySwoole\Http\AbstractInterface\Controller
{public $template_data = [];public function assign($name, $value) {$this->template_data[$name] = $value;}public function fetch($template_name) {return Render::getInstance()->render($template_name, $this->template_data);}
}

這樣我們就可以使用TP的風格進行模板傳值了效果和上面時一樣的 PS:暫時需要指定模板的路徑

function index(){$user_list = ['1', '2', '3', '4', '5'];$this->assign('user_list', $user_list);$this->response()->write($this->fetch('Index/index'));}

六、最后補充

{public static function initialize(){// TODO: Implement initialize() method.date_default_timezone_set('Asia/Shanghai');$config = new \EasySwoole\ORM\Db\Config(Config::getInstance()->getConf('MYSQL'));DbManager::getInstance()->addConnection(new Connection($config));}public static function mainServerCreate(EventRegister $register){// TODO: Implement mainServerCreate() method.$swooleServer = ServerManager::getInstance()->getSwooleServer();$swooleServer->addProcess((new HotReload('HotReload', ['disableInotify' => false]))->getProcess());Render::getInstance()->getConfig()->setRender(new ThinkTemplate());Render::getInstance()->getConfig()->setTempDir(EASYSWOOLE_TEMP_DIR);Render::getInstance()->attachServer(ServerManager::getInstance()->getSwooleServer());}public static function onRequest(Request $request, Response $response): bool{// TODO: Implement onRequest() method.return true;}public static function afterRequest(Request $request, Response $response): void{// TODO: Implement afterAction() method.}
}

' of line' . $throwable->getLine();//     return $msg;// }// 渲染邏輯實現// public function render(string $template, array $data = [], array $options = []): ?string// {//     foreach ($data as $k => $v) {//         $this->_topThinkTemplate->assign([$k => $v]);//     }//     // Tp 模板渲染函數都是直接輸出 需要打開緩沖區將輸出寫入變量中 然后渲染的結果//     ob_start();//     $this->_topThinkTemplate->fetch($template);//     $content = ob_get_contents();//     ob_end_clean();//     return $content;// }public function render(string $template, ?array $data = null, ?array $options = null): ?string{// return "your template is {$template} and data is " . json_encode($data);foreach ($data as $k => $v) {$this->_topThinkTemplate->assign([$k => $v]);}// Tp 模板渲染函數都是直接輸出 需要打開緩沖區將輸出寫入變量中 然后渲染的結果ob_start();$this->_topThinkTemplate->fetch($template);$content = ob_get_contents();ob_end_clean();return $content;}public function onException(\Throwable $throwable, $arg): string{// return $throwable->getTraceAsString();$msg = $throwable->getMessage() .
