Easyswoole中实现think-template模板引擎使用

在EasySwoole中实现Tp框架中think-template模板引擎的使用

1. 安装EasySwoole模板引擎驱动 composer require easyswoole/template (EasySwoole引入模板渲染驱动的形式，把需要渲染的数据，通过协程客户端投递到自定义的同步进程中进行渲染并返回结果。为何要如此处理，原因在于，市面上的一些模板引擎在Swoole协程下存在变量安全问题)

2. 安装ThinkPHP框架使用的模板引擎 composer require topthink/think-template

3. 实现渲染引擎，代码如下

<?php
namespace App;
use EasySwoole\Template\RenderInterface;
class Template implements RenderInterface
{
    protected $template;
    function __construct()
    {
        $config = [
            'view_path'	=>	EASYSWOOLE_ROOT.'/App/Views/',
            'cache_path'	=>	EASYSWOOLE_ROOT.'/Temp/runtime/',
        ];
        $this->template = new \think\Template($config);
    }
    public function render(string $template, array $data = [], array $options = []): ?string
    {
        // TODO: Implement render() method.
        ob_start();
        $this->template->assign($data);
        $this->template->fetch($template);
        $content = ob_get_contents() ;
        return $content;
    }
    public function afterRender(?string $result, string $template, array $data = [], array $options = [])
    {
        // TODO: Implement afterRender() method.
    }
    public function onException(\Throwable $throwable): string
    {
        // TODO: Implement onException() method.
        $msg = "{$throwable->getMessage()} at file:{$throwable->getFile()} line:{$throwable->getLine()}";
        trigger_error($msg);
        return $msg;
    }
}

4. HTTP服务中调用

<?php
/**
 * Created by PhpStorm.
 * User: yf
 * Date: 2018/5/28
 * Time: 下午6:33
 */

namespace EasySwoole\EasySwoole;


use EasySwoole\EasySwoole\Swoole\EventRegister;
use EasySwoole\EasySwoole\AbstractInterface\Event;
use EasySwoole\Http\Request;
use EasySwoole\Http\Response;
use EasySwoole\Template\Render;
use App\Template;

class EasySwooleEvent implements Event
{

    public static function initialize()
    {
        // TODO: Implement initialize() method.
        date_default_timezone_set('Asia/Shanghai');
    }

    public static function mainServerCreate(EventRegister $register)
    {
        // TODO: Implement mainServerCreate() method.
        //在全局的主服务中创建事件中，实例化该Render,并注入你的驱动配置
        Render::getInstance()->getConfig()->setRender(new Template());
        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.
    }
}

5.调用模板并输出

<?php
namespace App\HttpController\Admin;

use EasySwoole\Http\AbstractInterface\Controller;
use EasySwoole\Template\Render;

class Index extends Controller
{
    public function index()
    {
        $this->response()->write(Render::getInstance()->render('admin/index',['row'=> time()]));

    }

    public function console()
    {
        $this->response()->write(Render::getInstance()->render('admin/console'));
    }
}

这样就可以在我们的模板中，就像用Tp框架开发项目一样，使用熟悉的模板来开发项目了
