学习路之PHP--easyswoole使用视图和模板
- 一、安装依赖插件
- 二、 实现渲染引擎
- 三、注册渲染引擎
- 四、测试调用写的模板
- 五、优化
- 六、最后补充
一、安装依赖插件
composer require easyswoole/template:1.1.*
composer require topthink/think-template
相关版本：
"easyswoole/easyswoole": "3.3.x","easyswoole/orm": "^1.5","easyswoole/template": "1.1.*","topthink/think-template": "^2.0"
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 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

' 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

}App\HttpTemplate\Index\index.html
