MAUI 模糊路由在 PopAsync() 上匹配错误

Question

尝试从推送页面导航回来时出现错误

System.ArgumentException: 'Ambiguous routes matched for: //D_FAULT_TabBar14/IMPL_BooksPage/BooksPage/D_FAULT_ModalReader16 matches found: //D_FAULT_TabBar14/IMPL_BooksPage/BooksPage/D_FAULT_ModalReader16,//D_FAULT_TabBar14/IMPL_BooksPage/BooksPage/D_FAULT_ModalReader16 (Parameter 'uri')'

我正在使用 Shell 导航

<TabBar
    Shell.NavBarIsVisible="False"
    Shell.TabBarBackgroundColor="{DynamicResource Background}"
    Shell.TabBarForegroundColor="{DynamicResource HighlightedItem}"
    Shell.TabBarTitleColor="{DynamicResource HighlightedItem}"
    Shell.TabBarUnselectedColor="{DynamicResource DarkerBackground}">
    <ShellContent
    Title="წიგნები"
    ContentTemplate="{DataTemplate pages:BooksPage}"
    Icon="open_book.svg"
    Route="BooksPage" />
......

从 BooksPage 然后我像这样转到 Reader

ModalReader mr = new ModalReader(book);
await Shell.Current.Navigation.PushAsync(mr, true);

从阅读器到书签

BookmarksModal bm = new BookmarksModal(_viewModel.Book?.Title ?? "usaxelo", _viewModel.Sarchevi, (int x) =>
{
    Carousel.ScrollTo(x, animate: false);
});

await Shell.Current.Navigation.PushAsync(bm, true);

当我尝试弹出时，会抛出一个异常

           await Shell.Current.Navigation.PopAsync();

我做错了什么？

注册了路由和依赖项，但仍然出现相同的错误

  public AppShell()
  {
      InitializeComponent();

      Routing.RegisterRoute(nameof(Authenticator), typeof(Authenticator));
      Routing.RegisterRoute(nameof(MainPage), typeof(MainPage));
      Routing.RegisterRoute(nameof(LoginPage), typeof(LoginPage));
      Routing.RegisterRoute(nameof(BooksPage), typeof(BooksPage));
      //Routing.RegisterRoute(nameof(ReaderPage), typeof(ReaderPage));
      //Routing.RegisterRoute(nameof(ProfilePage), typeof(ProfilePage));
      //Routing.RegisterRoute("books/modalReader", typeof(ModalReader));
      //Routing.RegisterRoute("books/searchPage", typeof(BooksSeachPage));
      //Routing.RegisterRoute("books/reader/bookmarks", typeof(BookmarksModal));
      //Routing.RegisterRoute("books/reader/font", typeof(FontModal));
  }

builder.Services.AddTransient<SessionManagement>();

builder.Services.AddSingleton<MainPage>();
builder.Services.AddSingleton<Authenticator>();
builder.Services.AddSingleton<LoginPage>();
builder.Services.AddSingleton<BooksPage>();
//builder.Services.AddTransient<ReaderPage>();
//builder.Services.AddTransient<ProfilePage>();
//builder.Services.AddTransient<ModalReader>();
//builder.Services.AddTransient<BookmarksModal>();
//builder.Services.AddTransient<FontModal>();

如果检测到重复的路由，应用程序启动时将抛出 ArgumentException。如果层次结构中同一级别的两个或多个路由共享一个路由名称，也会引发此异常。

您已经在 Shell 视觉层次结构中注册了 BooksPage 的路由

<ShellContent
Title="წიგნები"
....
Route="BooksPage" />

所以你不必在后面的代码中再次注册它，只需删除这个即可，

Routing.RegisterRoute(nameof(BooksPage), typeof(BooksPage));
