Asp.Net Core 3.0 MVC - 文化 Cookie 的脚手架身份页面路由

Question

我已经在我的 Asp.Net Core MVC 3.0 应用程序中实现了这个用于本地化的 nuget 包，我发现它很棒。

https://github.com/LazZiya/ExpressLocalization

除了我的脚手架身份页面之外的所有页面都工作正常。

当我导航到我的脚手架 Register.cshtml 页面时，我遇到了一个问题，我的本地化 cookie 没有被放入 URL。但是，如果我手动将文化（例如 de 或 en 等）键入 URL，则本地化工作正常。

例如，当我点击注册 link时，URL应该是

但它总是

我还根据 these instructions 添加了 RouteTemplateModelConvention.cs class，但我认为它没有任何作用。它在评论中说它应该被自动调用。我已经放在根目录了 ~/RouteTemplateModelConvention.cs

这是我的文件夹结构：

我猜是因为身份页面的脚手架自动使用 Razor 页面进行注册和登录，所以我的 MVC 本地化实现不适用于这些。

但是...如果我手动将区域性（"en" 或 "de"）添加到浏览器 URL，它是工作，它只是没有自动拾取它。

我已经尝试了多种变体来使它正常工作，但我确信它很简单，我在 cookie 的路由中丢失了...有什么想法吗？

更新：

我尝试在我的共享 _Layout.cshtml 文件中使用 asp-route-culture=“@CultureInfo.CurrentCulture.Name” 将文化参数添加到 <a></a> link，但是我收到一条错误消息说 @CultureInfo 在当前上下文中不存在。

更新：

好的进展... 我将 @using System.Globalization 命名空间添加到我的布局文件中。现在 URL 是 https://localhost:44305/"de"/Identity/Account/Register 我想弄清楚为什么引号在 URL 中。有什么想法吗？

Answer 1

使用 asp-route-culture="@CultureInfo.CurrentCulture.Name" 应该可以解决问题。

在您的代码中，您似乎使用了引号“...” 它们应该是引号 "..." :)
