基于asp.net核的自定义语言代码路由问题

Question

我试图在使用asp.net核心3.1的控制器之前添加一个自定义语言代码，并且语言代码不是C#上的标准文化代码。

例如。

en =英语tch =中文

因此，其结果应当是：

localhost/en     -> Go to Home page in English

localhost/tch    -> Go to Home page in Chinese

localhost/       -> Should redirect to localhost/en 

also, there are other controller that need to include the language code as well

localhost/en/blog        -> Go to blog Listing page in English

localhost/blog           -> Redirect to localhost/en/blog and Go to blog Listing page

localhost/en/blog/{id}   -> Go to blog detail page in English

localhost/blog/{id}      -> Redirect to localhost/en/blog/{id}   and Go to blog detail page

localhost/en/event          -> Go to event Listing page in English

localhost/event             -> Redirect to localhost/en/event and Go to event Listing page

localhost/en/event/{id}     -> Go to event detail page in English

localhost/event/{id}        -> Redirect to localhost/en/event/{id}  and Go to event detail page

在startup.cs上，我使用UseEndpoints进行路由

  app.UseEndpoints(endpoints =>
                {
                    endpoints.MapControllerRoute(
                        name: "others",
                        pattern: "{language}/{controller}/{id?}",
                        defaults: new { action = "Index" });

                    endpoints.MapControllerRoute(
                       name: "default",
                       pattern: "{language}/{controller=Home}",
                       defaults: new { controller = "Home", action = "Index" });
            });

下面是我的博客控制器类：

      [Route("{language}/blog")]
        [Route("blog")]
        public async Task<IActionResult> Index(string language)
        {
            if (language == null || (!language.Equals("en") && !language.Equals("tch")))
                return  RedirectToAction("Index", new { language = "en" });
.......
        }

如果我输入localhost/en/blog并且语言参数可以从RedirectToAction捕获语言，那么上面的代码可以正常工作，但是当我试图使用时，语言变成了查询字符串localhost/blog? language =en，只是想知道是否有任何设置/编码错误.

有人能给我一些建议吗？谢谢

实现这一目标的最佳方法是创建一个自定义路由约束：https://learn.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-3.1#custom-route-constraints
