  How can I make the StatusCodePages support Localizer?

  Sep 17, 2019 09:05 AM|mywatermelon|LINK

  Here is the Configure:

      public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
          {
              if (env.IsDevelopment())
              {
                  app.UseDeveloperExceptionPage();
              }
              else
              {
                  app.UseExceptionHandler("/Error");
                  app.UseHttpsRedirection();
              }
  
              var SupportedCultures = new List<CultureInfo> {
                  new CultureInfo("en"),
                  new CultureInfo("zh-Hans"),
                  new CultureInfo("zh-Hant")
          };
              var options = new RequestLocalizationOptions
              {
                  DefaultRequestCulture = new RequestCulture("en"),
                  SupportedCultures = SupportedCultures,
                  SupportedUICultures = SupportedCultures
              };
              app.UseRequestLocalization(options);
              app.UseStaticFiles();
  
              app.UseStatusCodePagesWithReExecute("{culture}/StatusCode/{0}");
  
  
              var requestProvider = new RouteDataRequestCultureProvider();
              options.RequestCultureProviders.Insert(0, requestProvider);
  
              app.UseRouter(routes =>
              {
                  routes.MapMiddlewareRoute("{culture=en}/{*mvcRoute}", subApp =>
                  {
                      subApp.UseRequestLocalization(options);
                      subApp.UseRouting();
                      subApp.UseEndpoints(mvcRoutes =>
                      {
                          mvcRoutes.MapControllerRoute(
                              name: "default",
                              pattern: "{culture=en}/{controller=Home}/{action=Index}");
                          // map the .html suffix
                          mvcRoutes.MapControllerRoute(
                              name: "home.html",
                              pattern: "{culture=en}/{controller=Home}/{action}.html");
                      });
                  });
              });
          }

  And here is the StatusCodeController:

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Threading.Tasks;
  using Microsoft.AspNetCore.Mvc;
  
  namespace Test.Controllers
  {
      public class StatusCodeController : Controller
      {        
          [HttpGet("{culture}/StatusCode/{statusCode}")]
          public IActionResult Index(int statusCode)
          {
              return View(statusCode);
          }
      }
  }

  The Localizer works well.

  Whereas, when I navigate a URL which the page does not exist. It will only redirect to the default language 404Page, such as http://localhost:5009/en/StatusCode/404

  I have added the culture property inside the app.UseStatusCodePagesWithReExecute but it seems no works.

  How can I solve this? Thank you.

  Hi mywatermelon，

  You could not use the placeholder "{culture}" directly in the UseStatusCodePagesWithReExecute() method. You need to add a new StatusCodePages middleware to the pipeline to get the current culture.

  This is the method of redirection:

   app.UseStatusCodePages(async context =>
              {
                  var currentCulture = CultureInfo.CurrentCulture.Name;
                  var redirectPath = "/" + currentCulture + "/StatusCode/" + context.HttpContext.Response.StatusCode;
                  context.HttpContext.Response.Redirect(redirectPath);
              });

  This is the method of rewriting:

   app.UseStatusCodePages(async context =>
              {
                  var currentCulture = CultureInfo.CurrentCulture.Name;
                  var newPath = "/" + currentCulture + "/StatusCode/" + context.HttpContext.Response.StatusCode;
                  context.HttpContext.Request.Path = newPath;
                  await context.Next(context.HttpContext);
              });

  Best Regards ,

  No, it doesn't work.

  I added a breakpoint in the Visual Studio. When running a page which not exists, 

  var currentCulture = CultureInfo.CurrentCulture.Name;

  The codes above always get "en" even the URL is 'http://localhost:5009/zh-Hans/product/555.html' which the Localizer is zh-hans.

  Hi mywatermelon，

  Are you missing the method which you changed your CurrentCulture in you project ? here is my way,I put it in the index method of the home controller.

  public IActionResult Index()
          {
              Response.Cookies.Append(
              CookieRequestCultureProvider.DefaultCookieName,
              CookieRequestCultureProvider.MakeCookieValue(new RequestCulture("zh-Hant")),
              new CookieOptions { Expires = DateTimeOffset.UtcNow.AddYears(1) });
              return View();
          }

  Best Regards ,

  It works now. However, it needs to add the method inside every controller. 

  I remembered that the URL also store the Culture in my project, so I modified the code like this:

   app.UseStatusCodePages(async context =>
              {
                  await Task.Run(() =>
                  {
                      string currentCulture = "";
                      if (context.HttpContext.Request.Path.Value.Split('/').Length < 2)
                      {
                          currentCulture = "en";
                      }
                      else
                      {
                          string LanguageGet = context.HttpContext.Request.Path.Value.Split('/')[1];
                          currentCulture = SupportedCultures.Find(X => X.Name == LanguageGet) == null ? "en" : SupportedCultures.Find(X => X.Name == LanguageGet).Name;
                      }
                      var redirectPath = "/" + currentCulture + "/StatusCode/" + context.HttpContext.Response.StatusCode;
                      context.HttpContext.Response.Redirect(redirectPath);
                  });
              });

  It works. Aha.
