--description--

HTML 服务器通常有一个或多个用户可以访问的目录。你可以将应用程序所需的静态资源 (样式表、脚本、图片) 放在那里。在 Express 中你可以使用中间件express.static(path)来设置此功能,它的参数就是静态资源文件的绝对路径。如果你不知道什么是中间件,也不用担心。我们稍后将详细讨论此事。一个最基本的中间件可以看做是一个函数,它拦截路由处理方法,并在里面添加了一点别的信息。使用app.use(path, middlewareFunction)方法来加载一个中间件。它的第一个参数是可选的,如果没设置第一个参数,那么应用的所有请求都会经过这个中间件处理。

--instructions--

使用app.use()来加载express.static()中间件,让所有的请求都能访问我们的静态资源目录。静态资源的绝对路径是__dirname + /public

现在 app 就能正常返回一个样式文件了,访问 app 根路径时,静态资源目录的文件就会被加载进来,现在你的首页看起来应该好些了!

--hints--

应用的静态资源文件应该来自/public目录

(getUserInput) =>
  $.get(getUserInput('url') + '/style.css').then(
    (data) => {
      assert.match(
        data,
        /body\s*\{[^\}]*\}/,
        'Your app does not serve static assets'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
