# --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 中可以使用中间件 `express.static(path)` 来设置此功能,它的参数 `path` 就是包含静态资源文件的绝对路径。
|
|
|
|
如果你不知道什么是中间件……别担心,我们将在后面详细讨论。 其实,中间件就是一个拦截路由处理方法并在里面添加一些信息的函数。 使用 `app.use(path, middlewareFunction)` 方法来加载一个中间件, 它的第一个参数 `path` 是可选的, 如果没设置第一个参数,那么所有的请求都会经过这个中间件处理。
|

# --instructions--

|
|
使用 `app.use()` 为路径 `/public` 的请求安装 `express.static()` 中间件, 静态资源的绝对路径是 `__dirname + /public`。
|
|
|
|
现在应用应该能提供 CSS 样式表, 请注意, `/public/style.css` 文件被项目模板的 `/views/index.html` 引用, 首页应该更好看了。
|
|
|
|
# --hints--
|
|
|
|
应用应该将资源文件从 `/public` 目录发送到 `/public` 路径
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/public/style.css').then(
|
|
(data) => {
|
|
assert.match(
|
|
data,
|
|
/body\s*\{[^\}]*\}/,
|
|
'Your app does not serve static assets'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
