17.3.1
服务器端渲染的网站
如果你在使用
Express
来渲染动态
HTML
，那么“任何开始于
/static/
的都是静态资源，除
此之外都是动态资源。”按这种做法，把所有的（动态生成的）
URL
指定成什么都可以
（当然，不能是以
/static/
开头的）
，而所有的静态资源都会加上
/static/
前缀：
<img src="/static/img/meadowlark-logo-1.png" alt="Meadowlark Logo">
Welcome to <a href="/about">Meadowlark Travel</a>.
目前为止，本书一直在使用
Express
的
static
中间件，就好像所有这些静态资源都托管在
服务器的根目录中一样。也就是说，如果把一个静态资源
foo.png
放到
public
目录下
，就
要使用
URL
路径
/foo.png
而不是
/static/foo.png
来引用它
。当然，也可以在已有的
public
目录下创建
static
子目录
，那么
/public/static/foo.png
的
URL
就是
/static/foo.png
，但创建
static
子目录的做法似乎显得有点儿愚蠢
。幸运的是，如果使用
static
中间件，就可以不
这样做。只需要在调用
app.use
时指定一个不同的路径：
app.use('/static', express.static('public'))
现在就可以在开发环境中使用跟将来的生产环境一样的
URL
结构了 ...
