How to handle AuthenticationState in WPF?
问题
我有一个使用 JWT 从 API 获取用户声明的 .NET 7 WPF 应用程序。登录过程正常工作。但是我不知道应该在 WPF 部分存储用户信息在哪里。在 ASP.NET Core 中，我使用 AuthenticationStateProvider，但似乎在 WPF 中没有这样的选项。
无论如何，以下是我目前的代码：
public partial class MainWindow{private readonly IHttpClientFactory _httpClientFactory;private readonly ILogger<MainWindow> _logger;public MainWindow(IHttpClientFactory httpClientFactory, ILogger<MainWindow> logger){InitializeComponent();_httpClientFactory = httpClientFactory;_logger = logger;}private async void LoginButton_Click(object sender, RoutedEventArgs e){var client = _httpClientFactory.CreateClient();var tokenResponse =await client.PostAsJsonAsync("https://localhost:5001/api/login/pos", new LoginCredentials(UsernameTextBox.Text, PasswordBox.Password));if (tokenResponse.IsSuccessStatusCode){LoginResult loginResult = await tokenResponse.Content.ReadFromJsonAsync<LoginResult>();string token = loginResult.Token;SetPrincipal(token);}else{MessageBox.Show(await tokenResponse.Content.ReadAsStringAsync(), "Login failed");}}private void SetPrincipal(string token){var tokenHandler = new JwtSecurityTokenHandler();var jwtToken = tokenHandler.ReadJwtToken(token);var claims = jwtToken.Claims;var identity = new ClaimsIdentity(claims);var principal = new ClaimsPrincipal(identity);System.Threading.Thread.CurrentPrincipal = principal;AppDomain.CurrentDomain.SetThreadPrincipal(principal);}}
我正在阅读关于 Thread.CurrentPrincipal 的内容，但不确定这是否是正确的方法。
在 .NET 7 WPF 应用程序中存储和访问用户信息是否有常见的方法，还是我需要自己实现它？

I am having a net 7 Wpf app that get's the user claims from an API on login using jwt. The login process is working. But i don't know where i should store the user's information on the Wpf side. In asp.net core I use the AuthenticationStateProvider but it seems there is no such option for Wpf.
Anyway here's the current code i have:
public partial class MainWindow{private readonly IHttpClientFactory _httpClientFactory;private readonly ILogger<MainWindow> _logger;public MainWindow(IHttpClientFactory httpClientFactory, ILogger<MainWindow> logger){InitializeComponent();_httpClientFactory = httpClientFactory;_logger = logger;}private async void LoginButton_Click(object sender, RoutedEventArgs e){var client = _httpClientFactory.CreateClient();var tokenResponse =await client.PostAsJsonAsync("https://localhost:5001/api/login/pos", new LoginCredentials(UsernameTextBox.Text, PasswordBox.Password));if (tokenResponse.IsSuccessStatusCode){LoginResult loginResult = await tokenResponse.Content.ReadFromJsonAsync<LoginResult>();string token = loginResult.Token;SetPrincipal(token);}else{MessageBox.Show(await tokenResponse.Content.ReadAsStringAsync(), "Login failed");}}private void SetPrincipal(string token){var tokenHandler = new JwtSecurityTokenHandler();var jwtToken = tokenHandler.ReadJwtToken(token);var claims = jwtToken.Claims;var identity = new ClaimsIdentity(claims);var principal = new ClaimsPrincipal(identity);System.Threading.Thread.CurrentPrincipal = principal;AppDomain.CurrentDomain.SetThreadPrincipal(principal);}}
I was reading about Thread.CurrentPrincipal but I am unsure if that is the correct approach.
Is there a common approach to store and access user information in a net 7 Wpf app or do I have to implement it myself?

如果您没有要求跨不同实例/运行的应用程序存储信息，您可以将其存储在应用程序的某个变量中，例如：
public static class ApplicationService{internal static string Token { get; set; }}
如果您在应用程序中使用IPrincipal执行授权操作，使用Thread.CurrentPrincipal属性存储它似乎是一个不错的方法。

If you don't have a requirement to store the information across different instances/runs of your app, you could just store it in a variable somewhere in your application, e.g.:
public static class ApplicationService{internal static string Token { get; set; }}
If you use an IPrincipal to perform authorization in your app, storing it using the Thread.CurrentPrincipal property seems like a good approach.
