使用 ASP.NET Core 1.0的MVC 6 RC1,您可以在调用Startup.Configure
时映射app.UseMvc
函数中的路由。我已经映射了一个“spa-fallback”路由,它将确保HomeController
和Index
视图是默认值,如下所示:
public void Configure(IApplicationBuilder app,
IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
// ... omitted for brevity
app.UseExceptionHandler("/Home/Error");
app.UseStatusCodePagesWithRedirects("/Home/Error/{0}");
app.UseMvc(routes =>
{
routes.MapRoute("default", "{controller=Home}/{action=Index}/{id?}");
routes.MapRoute("spa-fallback", "{*anything}", new { controller = "Home", action = "Index" });
routes.MapWebApiRoute("defaultApi", "api/{controller}/{id?}");
});
}
我希望回退,以便我的 Angular2 应用程序的路由不会导致HTTP状态代码 404,Not Found 。但是,当用户无意中尝试导航到不存在的页面视图时,我还需要正确处理。您可能会注意到我还调用了app.UseStatusCodePagesWithRedirects("/Home/Error/{0}");
。
使用状态代码和“spa-fallback”路线重定向到我的错误页面的调用似乎是互斥的 - 这意味着我似乎只有一个或另一个(但遗憾的是不是两者)< / em>的。有谁知道如何才能让两全其美?

我花了一些时间来弄清楚如何在不使用MVC提供索引的情况下执行此操作,并仍然收到丢失文件的404s。这是我的http管道:
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseMvc(
routes => {
routes.MapRoute(
name: "api",
template: "api/{controller}/{action}/{id?}");
// ## commented out since I don't want to use MVC to serve my index.
// routes.MapRoute(
// name:"spa-fallback",
// template: "{*anything}",
// defaults: new { controller = "Home", action = "Index" });
});
// ## this serves my index.html from the wwwroot folder when
// ## a route not containing a file extension is not handled by MVC.
// ## If the route contains a ".", a 404 will be returned instead.
app.MapWhen(context => context.Response.StatusCode == 404 &&
!Path.HasExtension(context.Request.Path.Value),
branch => {
branch.Use((context, next) => {
context.Request.Path = new PathString("/index.html");
Console.WriteLine("Path changed to:" + context.Request.Path.Value);
return next();});
branch.UseStaticFiles();
});
}

我提出了两种可能的解决方法/解决方案。
ASP.NET Core 1.0,RC1
特别是 Angular2 ,我们可以简单地换出LocationStrategy
。例如,在我的wwwroot/app/boot.ts
中,我有以下内容:
import {provide} from "angular2/core";
import {bootstrap} from "angular2/platform/browser";
import {LocationStrategy, HashLocationStrategy, ROUTER_PROVIDERS} from "angular2/router";
import {HTTP_PROVIDERS} from "angular2/http";
import {AppComponent} from "./app.component"
bootstrap(AppComponent,
[
ROUTER_PROVIDERS,
HTTP_PROVIDERS,
provide(LocationStrategy, { useClass: HashLocationStrategy })
]);
请注意,我正在使用provide
功能覆盖标准LocationStrategy
和HashLocationStrategy
。这会在网址中添加#
并阻止MVC错误地抛出 404&#39> ,但也可以正确处理 404&#strong>的响应用户手动键入不存在的 URL 。
ASP.NET Core 1.0,RC2
只需使用Microsoft.AspNet.NodeServices
即可。在此库中,AngularServices
和ReactServices
都允许通过MapSpaFallbackRoute
函数专门映射SPA路由。我声明我们需要等待 RC2 ,并了解当前的实现并未完全按预期运行。

试试这个:
public void Configure(IApplicationBuilder app,
IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
app.UseExceptionHandler("/Home/Error");
app.UseStatusCodePagesWithRedirects("/Home/Error/{0}");
app.UseMvc(routes =>
{
routes.MapRoute("default", "{controller=Home}/{action=Index}/{id?}");
routes.MapWebApiRoute("defaultApi", "api/{controller}/{id?}");
});
app.Run(async context =>
{
context.Response.Redirect("/Home/Index");
await Task.CompletedTask;
});
}
app.Run()将捕获与之前定义的任何路由不匹配的所有请求。通过这种方式,您可以获得自定义spa回退并同时使用app.UseStatusCodePagesWithRedirects()。
