Asp.Net Core 3.0 MVC - 为Culture Cookie提供脚手架式身份页面路由服务

问题描述 投票：0回答：1

我已经在我的Asp.Net Core MVC 3.0应用中实现了这个nuget包的本地化，并且发现它非常棒。

https:/github.comLazZiyaExpressLocalization）。

除了我的脚手架身份页面外，所有页面都能正常工作。

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中。但如果我输入文化（如 de 或 en 等）手动添加到URL中，本地化工作正常。

例如，当我点击 注册 链接的网址应该是 enter image description here

反而总是

我还增加了一个 RouteTemplateModelConvention.cs。 根据 本说明但我不认为它在做什么。它在注释中说它应该被自动调用。我把它放在了根目录下 ~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了Razor页面来注册和登录，所以我的MVC本地化实现对这些页面不起作用。

但是...它 它是 如果我在浏览器的URL中手动添加文化（"en "或 "de"），它就能正常工作，只是不能自动接收。

我尝试了很多方法来解决这个问题，但我确信是我在cookie的路由中遗漏了一些简单的东西......有什么想法吗？

更新。

我试着将文化参数添加到 <a></a> 连接 asp-route-culture=“@CultureInfo.CurrentCulture.Name” 在我的共同 _Layout.cshtml 文件，但得到一个错误，说 @CultureInfo 在当前上下文中不存在。

更新一下。

好了，有了进展，我添加了 @using System.Globalization 命名空间到我的布局文件.现在URL是 https://localhost:44305/"de"/Identity/Account/Register我想弄明白为什么URL中会出现倒逗号？有什么好办法吗？

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

在你的代码中，似乎你使用了倒置的逗号。“...” 要加引号 "..." :)
