### 配置静态资源
|
|
|
|
|
|
2019-07-30 17:45:12 +08:00
|
|
|
|
如果您希望 `Swoole` 来管理静态资源,请在 `config/autoload/server.php` 配置中增加以下配置。
|
2019-07-30 17:00:47 +08:00
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
return [
|
|
|
|
|
'settings' => [
|
|
|
|
|
...
|
2019-07-30 17:45:12 +08:00
|
|
|
|
// 静态资源
|
2019-07-30 17:00:47 +08:00
|
|
|
|
'document_root' => BASE_PATH . '/public',
|
|
|
|
|
'static_handler_locations' => ['/'],
|
|
|
|
|
'enable_static_handler' => true,
|
|
|
|
|
],
|
|
|
|
|
];
|
|
|
|
|
|
|
|
|

## 视图渲染引擎
|
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
官方目前支持 `Blade` 和 `Smarty` 两种模板,默认安装 [hyperf/view](https://github.com/hyperf-cloud/view) 时不会自动安装任何模板引擎,需要您根据自身需求,自行安装对应的模板引擎,使用前必须安装任一模板引擎。
|

|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
### 安装 Blade 引擎
|
2019-07-27 13:52:40 +08:00
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
```bash
|
2019-07-27 13:52:40 +08:00
|
|
|
|
composer require duncan3dc/blade
|
|
|
|
|
```
|
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
### 安装 Smarty 引擎
|
2019-07-27 13:52:40 +08:00
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
```bash
|
2019-07-27 13:52:40 +08:00
|
|
|
|
composer require smarty/smarty
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 接入其他模板
|
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
假设我们想要接入一个虚拟的模板引擎名为 `TemplateEngine`,那么我们需要在任意地方创建对应的 `TemplateEngine` 类,并实现 `Hyperf\View\Engine\EngineInterface` 接口。
|
2019-07-27 13:52:40 +08:00
|
|
|
|
|
|
|
|
|
```php
|
|
|
|
|
<?php
|
|
|
|
|
|
|
|
|
|
declare(strict_types=1);
|
|
|
|
|
|
|
|
|
|
namespace App\Engine;
|
|
|
|
|
|
|
|
|
|
class TemplateEngine implements EngineInterface
|
|
|
|
|
{
|
|
|
|
|
public function render($template, $data, $config): string
|
|
|
|
|
{
|
2019-07-28 01:57:53 +08:00
|
|
|
|
// 实例化对应的模板引擎的实例
|
|
|
|
|
$engine = new TemplateInstance();
|
|
|
|
|
// 并调用对应的渲染方法
|
|
|
|
|
return $engine->render($template, $data);
|
2019-07-27 13:52:40 +08:00
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
2019-07-28 01:57:53 +08:00
|
|
|
|
然后修改视图组件的配置:
|
2019-07-27 13:52:40 +08:00
|
|
|
|
|
|
|
|
|
```php
|
|
|
|
|
<?php
|
|
|
|
|
|
|
|
|
|
use App\Engine\TemplateEngine;
|
|
|
|
|
|
|
|
|
|
return [
|
2019-07-28 01:57:53 +08:00
|
|
|
|
// 将 engine 参数改为您的自定义模板引擎类
|
2019-07-27 13:52:40 +08:00
|
|
|
|
'engine' => TemplateEngine::class,
|
|
|
|
|
'mode' => Mode::TASK,
|
|
|
|
|
'config' => [
|
|
|
|
|
'view_path' => BASE_PATH . '/storage/view/',
|
|
|
|
|
'cache_path' => BASE_PATH . '/runtime/view/',
|
|
|
|
|
],
|
|
|
|
|
];
|
|
|
|
|
```
|
2019-08-03 12:38:22 +08:00
|
|
|
|
|
|
|
|
|
## 使用
|
|
|
|
|
|
|
|
|
|
以下以 `BladeEngine` 为例,首先在对应的目录里创建视图文件 `index.blade.php`。
|
|
|
|
|
|
|
|
|
|
```blade
|
|
|
|
|
<!DOCTYPE html>
|
|
|
|
|
<html lang="en">
|
|
|
|
|
<head>
|
|
|
|
|
<meta charset="UTF-8">
|
|
|
|
|
<title>Hyperf</title>
|
|
|
|
|
</head>
|
|
|
|
|
<body>
|
|
|
|
|
Hello, {{ $name }}. You are using blade template now.
|
|
|
|
|
</body>
|
|
|
|
|
</html>
|
|
|
|
|
```
|
|
|
|
|
|

|
|
|
|
控制器中获取 `Hyperf\View\Render` 实例,然后调用 `render` 方法并传递视图文件地址 `index` 和 `渲染数据` 即可,文件地址忽略视图文件的后缀名。
|
2019-08-03 12:38:22 +08:00
|
|
|
|
|
|
|
|
|
```php
|
|
|
|
|
<?php
|
|
|
|
|
|
|
|
|
|
declare(strict_types=1);
|
|
|
|
|
|
|
|
|
|
namespace App\Controller;
|
|
|
|
|
|
|
|
|
|
use Hyperf\HttpServer\Annotation\AutoController;
|
|
|
|
|
use Hyperf\View\RenderInterface;
|
|
|
|
|
|
|
|
|
|
/**
|
|
|
|
|
* @AutoController
|
|
|
|
|
*/
|
|
|
|
|
class ViewController
|
|
|
|
|
{
|
|
|
|
|
public function index(RenderInterface $render)
|
|
|
|
|
{
|
|
|
|
|
return $render->render('index', ['name' => 'Hyperf']);
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
访问对应的 URL,即可获得如下所示的视图页面:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
Hello, Hyperf. You are using blade template now.
|
|
|
|
|
```
|
|
|
|
|
