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'));
}

Render::getInstance()->attachServer(ServerManager::getInstance()->getSwooleServer());
}
public static function onRequest(Request $request, Response $response): bool
