如何使用node.js实现虚拟目录并表达？

I want to use the express static server configuration for implementing an static server:

我想使用express静态服务器配置来实现静态服务器：

app.configure(function() {
    app.use(express.static(__dirname + '/public'));
});

But I want to map the URL http://myhost/url1 to directory C:\dirA\dirB and http://myhost/url2 to directory C:\dirC

但我想将URL http：// myhost / url1映射到目录C：\ dirA \ dirB，将http：// myhost / url2映射到目录C：\ dirC

How can it be implemented using express.static?

Depending on how many directories you're planning to map this way, you could simply make symlinks for those directories in your public folder.

根据您计划以这种方式映射的目录数量，您可以简单地为公用文件夹中的这些目录创建符号链接。

In Windows:

在Windows中：

mklink /D c:\dirA\dirB public\url1

In Linux or OSX:

在Linux或OSX中：

ln -s /dirA/dirB public/url1

Then your static assets server should serve from those directories transparently (I've never tested on Windows but I don't see why it wouldn't work).

那么你的静态资产服务器应该透明地从这些目录中提供服务（我从来没有在Windows上测试，但我不明白为什么它不起作用）。

Alternatively, if you wanted to include some kind of dynamic routing, you could write your own middleware to replace express.static which is actually connect.static under the hood. Take a look at static.js in the connect source and see how it's implemented, it should be fairly straightforward to write your own variation.

或者，如果你想要包含某种动态路由，你可以编写自己的中间件来替换express.static，它实际上是connect.static。看一下connect source中的static.js，看看它是如何实现的，编写自己的变体应该相当简单。

This should work for you:

这应该适合你：

var serveStatic = require( "serve-static" );
app.use('/url1', serveStatic('c:\\dirA\\dirB'));
app.use('/url2', serveStatic('C:\\dirC'));

Take a look at the documentation for app.use().

看一下app.use（）的文档。
