ASP.net core MVC 捕获所有路由服务静态文件

问题描述

有没有办法让 catch all 路由服务于静态文件?

Is there a way to make a catch all route serve a static file?

看这个http://blog.nbellocam.me/2016/03/21/routing-angular-2-asp-net-core/

我基本上想要这样的东西:

I basically want something like this:

        app.UseMvc(routes =>
        {
            routes.MapRoute("default", "{controller}/{action=Index}");

            routes.MapRoute("spa", "{*url}"); // This should serve SPA index.html
        });

所以任何与 MVC 控制器不匹配的路由都会提供 wwwroot/index.html

So any route that doesn't match an MVC controller will serve up wwwroot/index.html

推荐答案

如果您已经处于路由阶段，那么您已经过了在管道中提供静态文件的阶段.您的初创公司将如下所示:

If you're already in the routing stage, you've gone past the point where static files are served in the pipeline. Your startup will look something like this:

app.UseStaticFiles();

...

app.UseMvc(...);

这里的顺序很重要.因此，您的应用将首先查找静态文件，这从性能的角度来看是有意义的 - 如果您只想丢弃静态文件，则无需运行 MVC 管道.

The order here is important. So your app will look for static files first, which makes sense from a performance standpoint - no need to run through MVC pipeline if you just want to throw out a static file.

您可以创建一个包罗万象的控制器操作，该操作将返回文件的内容.例如(窃取您评论中的代码):

You can create a catch-all controller action that will return the content of the file instead. For example (stealing the code in your comment):

public IActionResult Spa()
{
    return File("~/index.html", "text/html");
}
