是否可以从 wwwroot 文件夹外部提供静态文件?

Is it possible to serve static files from outside the wwwroot folder?(是否可以从 wwwroot 文件夹外部提供静态文件?)

问题描述

我有一个具有以下结构的 ASP.NET MVC 6 项目:

I have an ASP.NET MVC 6 project with the following structure:

project/
  wwwroot/
  custom/
  project.json

我想将 custom 中的文件作为虚拟文件夹提供到 http://localhost/custom 中，而无需在开发过程中复制它们.

I want to serve files from custom as it if was a virtual folder into http://localhost/custom without having to copy them during development.

是否可以在没有来自 IIS 的虚拟文件夹的情况下在 vNext 中执行此操作(例如，使用 StaticFile 中间件)?

Is it possible to do this in vNext without a virtual folder from IIS (say, using the StaticFile middleware)?

推荐答案

使用中间件时可以在options对象上设置文件提供者.

You can set the file provider on the options object when using the middleware.

app.UseStaticFiles(new StaticFileOptions() {
    FileProvider = new PhysicalFileProvider(@"C:PathToFiles"),
    RequestPath = new PathString("/somepath")
})
