Laravel 5：即使已安装软件包，也找不到类“HTML”答案

【问题标题】：Laravel 5: Class 'HTML' not found even though package has been installedLaravel 5：即使已安装软件包，也找不到类“HTML”
【发布时间】：2015-08-11 03:47:42
【问题描述】：

我知道这不再是嵌入式软件包了。在我的composer.json 我有：

"require": {
    ...stuff...
    "illuminate/html": "5.*"
}, etc.

在app.php 我有：

'providers' => [
    ...stuff...
    'Illuminate\Html\HtmlServiceProvider',
    ...more stuff...
],
'aliases' => [
    ...stuff...
    'Html' => 'Illuminate\Html\HtmlFacade'
], etc.

我已经运行composer update，为什么我使用HTML::script()时它无法识别？这是引发错误的 Blade 模板：

<!DOCTYPE HTML>

<html lang="en">

<!-- USER LOGIN SECURITY -->
<!-- require('redis-session.php');
RedisSession::start();

@if (!isset($_SESSION['HTTP_SHIB_EP_EMAILADDRESS']))
    header('Location: https://resviz.ncl.ac.uk/signin?redirect=https://resviz.ncl.ac.uk/wos/index.php');
    die();
@endif -->

我正在将这个现有的 Web 应用程序移动到 Laravel 中，因此我正在尝试实现各种 Blade 组件。在这种情况下，将 <script src="script.js"></script> 更改为 {{ HTML::script('js/script.js') }}。我不明白为什么 HTML 类没有被识别...

【问题讨论】：

你跑了吗 - composer dump-autoload ？
刚刚尝试过 - 没有变化...
将别名从“Html”更改为“HTML”。错字！ :)
面部护理。完美，谢谢！

【解决方案1】：

您可以使用{!! HTML::script('whatever') !!}。

在 Laravel 5 或 5.1 中，大多数情况下你可以使用 {!! codes !!} 而不是 {{ codes }}。

【讨论】：

{!!和{{有什么区别？
