ASP.NET 5 MVC 6：如何配置启动以在不在任何mvc路由上时发送html文件

Question

I'm building a SPA application using React-Router to handle the front-end routing.

I'm trying to configure the ASP.NET 5 Startup.cs file to use MVC but when a route does not match any of my API routes to send the index.html file so that it will be able to handle react-routers browser history implementation as stated here .

So far i've only been able to get it to send the index.html file when on the default route, ie nothing after the localhost:3000.

My Startup Configure method so far. Thank you

        app.UseIdentity();
        app.UseIISPlatformHandler();
        app.UseDefaultFiles(new DefaultFilesOptions {
            DefaultFileNames = new List<string> { "index.html"}
        });
        app.UseStaticFiles();
        app.UseMvc();

Pretty simple, with app.UseStatusCodePagesWithReExecute("/");

public void Configure(IApplicationBuilder app)
{
    app.UseIISPlatformHandler();

    app.UseStatusCodePagesWithReExecute("/");

    app.UseDefaultFiles();
    app.UseStaticFiles();
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}"
        );
    });
}

This will return the index.html page in your wwwroot , even if you get a 404. It will however only change the page, but not the URL.

Alternatively , you might not want to do a page redirect since you are doing a SPA, but if you really need to update the URL you can just do a simple redirect from a controller, like so:

public class RedirectController : Controller
{
    public IActionResult Index()
    {
        return Redirect(Url.Content("~/"));
    }
}

and then in your startup update this:

app.UseStatusCodePagesWithReExecute("/redirect");
