学习路之PHP--easyswoole使用视图和模板

一、安装依赖插件

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

二、实现渲染引擎

在 App 目录下新建 System 目录存放渲染引擎实现的代码 ThinkTemplate.php

<?php
namespace App\System;use EasySwoole\Template\RenderInterface;
use think\facade\Template;class ThinkTemplate implements RenderInterface
{// tp模板类对象private $_topThinkTemplate;public function __construct(){$temp_dir = sys_get_temp_dir();$config = ['view_path' => EASYSWOOLE_ROOT . '/App/HttpTemplate/', // 模板存放文件夹根目录'cache_path' => $temp_dir, // 模板文件缓存目录'view_suffix' => 'html' // 模板文件后缀];$this->_topThinkTemplate = new \think\Template($config);}public function afterRender(?string $result, string $template, array $data = [], array $options = []){}// 当模板解析出现异常时调用public function onException(\Throwable $throwable): string{$msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();return $msg;}// 渲染逻辑实现public function render(string $template, array $data = [], array $options = []): ?string{foreach ($data as $k => $v) {$this->_topThinkTemplate->assign([$k => $v]);}// Tp 模板渲染函数都是直接输出 需要打开缓冲区将输出写入变量中 然后渲染的结果ob_start();$this->_topThinkTemplate->fetch($template);$content = ob_get_contents();ob_end_clean();return $content;}
}

由于版本问题：报错

<?php
namespace App\System;use EasySwoole\Template\RenderInterface;
use think\facade\Template;class ThinkTemplate implements RenderInterface
{// tp模板类对象private $_topThinkTemplate;public function __construct(){$temp_dir = sys_get_temp_dir();$config = ['view_path' => EASYSWOOLE_ROOT . '/App/HttpTemplate/', // 模板存放文件夹根目录'cache_path' => $temp_dir, // 模板文件缓存目录'view_suffix' => 'html' // 模板文件后缀];$this->_topThinkTemplate = new \think\Template($config);}public function afterRender(?string $result, string $template, array $data = [], array $options = []){}// 当模板解析出现异常时调用// public function onException(\Throwable $throwable): string// {//     $msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();//     return $msg;// }// 渲染逻辑实现// public function render(string $template, array $data = [], array $options = []): ?string// {//     foreach ($data as $k => $v) {//         $this->_topThinkTemplate->assign([$k => $v]);//     }//     // Tp 模板渲染函数都是直接输出 需要打开缓冲区将输出写入变量中 然后渲染的结果//     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 => $v]);}// Tp 模板渲染函数都是直接输出 需要打开缓冲区将输出写入变量中 然后渲染的结果ob_start();$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、注册渲染引擎

需要对模板引擎进行实例化并且注入到EasySwoole 的视图中在项目根目录 EasySwooleEvent.php 中 mainServerCreate 事件函数中进行注入代码如下

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

// 设置Http服务模板类
Render::getInstance()->getConfig()->setRender(new ThinkTemplate());
Render::getInstance()->getConfig()->setTempDir(EASYSWOOLE_TEMP_DIR);
Render::getInstance()->attachServer(ServerManager::getInstance()->getSwooleServer());

四、测试调用写的模板

在App目录下创建 HttpTemplate 目录 PS:之前在 ThinkTemplate.php 文件中设置的路径

创建文件 /App/HttpTemplate/Admin/Index/index.html 路径与模块控制器响应函数相对应你也可以按照自己的喜欢来

<!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 中调用

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、优化

这样的模板传值非常麻烦有木有还必须要放在一个数组中一次性传给 Render 对象我们可以将操作封装到基类控制器实现类似于TP框架的操作代码如下

<?php
/*** 基础控制器类*/
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);}
}

这样我们就可以使用TP的风格进行模板传值了效果和上面时一样的 PS:暂时需要指定模板的路径

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

六、最后补充

EasySwooleEvent.php

<?php
namespace EasySwoole\EasySwoole;use EasySwoole\EasySwoole\Swoole\EventRegister;
use EasySwoole\EasySwoole\AbstractInterface\Event;
use EasySwoole\Http\Request;
use EasySwoole\Http\Response;
use App\Process\HotReload;
use EasySwoole\ORM\DbManager;
use EasySwoole\ORM\Db\Connection;
use App\System\ThinkTemplate;
use EasySwoole\Template\Render;
use EasySwoole\Template\RenderInterface;class EasySwooleEvent implements Event
{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.}
}

App\System\ThinkTemplate.php

<?php
namespace App\System;use EasySwoole\Template\RenderInterface;
use think\facade\Template;class ThinkTemplate implements RenderInterface
{// tp模板类对象private $_topThinkTemplate;public function __construct(){$temp_dir = sys_get_temp_dir();$config = ['view_path' => EASYSWOOLE_ROOT . '/App/HttpTemplate/', // 模板存放文件夹根目录'cache_path' => $temp_dir, // 模板文件缓存目录'view_suffix' => 'html' // 模板文件后缀];$this->_topThinkTemplate = new \think\Template($config);}public function afterRender(?string $result, string $template, array $data = [], array $options = []){}// 当模板解析出现异常时调用// public function onException(\Throwable $throwable): string// {//     $msg = $throwable->getMessage() . " is file " . $throwable->getFile() . ' of line' . $throwable->getLine();//     return $msg;// }// 渲染逻辑实现// public function render(string $template, array $data = [], array $options = []): ?string// {//     foreach ($data as $k => $v) {//         $this->_topThinkTemplate->assign([$k => $v]);//     }//     // Tp 模板渲染函数都是直接输出 需要打开缓冲区将输出写入变量中 然后渲染的结果//     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 => $v]);}// Tp 模板渲染函数都是直接输出 需要打开缓冲区将输出写入变量中 然后渲染的结果ob_start();$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;}
}

App\HttpController\Index.php

<?phpnamespace App\HttpController;use EasySwoole\Template\Render;class Index extends BaseController
{/*** */public function index(){$user_list = ['1', '2', '3', '4', '5'];$this->assign('user_list', $user_list);$this->response()->write($this->fetch('Index/index'));}}

App\HttpController\BaseController.php

<?php

{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);}
}

App\HttpTemplate\Index\index.html
