刷新ASP.Net Core Identity中的用户Cookie票证

问题描述

在ASP.NET Core Web应用程序的控制器中，我想刷新用户并声明存储在客户端上的cookie票证.

In a controller in an ASP.NET Core web application I want to refresh the user and claims in the cookie ticket stored on the client.

客户端已通过身份验证和授权，ASP.NET Core Identity将此信息存储在cookie票证中-现在在某些Controller动作中，我想刷新cookie中的数据.

The client is authenticated and authorized, ASP.NET Core Identity stores this Information in the cookie ticket - now in some Controller actions I want to refresh the data in the cookie.

SignInManager具有刷新RefreshSignInAsync的功能，但不接受HttpContext.User作为参数.

The SignInManager has a function to refresh RefreshSignInAsync, but it does not accept HttpContext.User as parameter.

[HttpPost("[action]")]
[Authorize]
public async Task<IActionResult> Validate()
{
  // todo: update the Client Cookie
  await _signInManager.RefreshSignInAsync(User); // wrong type
}

如何刷新cookie?

How do I refresh the cookie?

推荐答案

public static class HttpContextExtensions
{
    public static async Task RefreshLoginAsync(this HttpContext context)
    {
        if (context.User == null)
            return;

        // The example uses base class, IdentityUser, yours may be called
        // ApplicationUser if you have added any extra fields to the model
        var userManager = context.RequestServices
            .GetRequiredService<UserManager<IdentityUser>>();
        var signInManager = context.RequestServices
            .GetRequiredService<SignInManager<IdentityUser>>();

        IdentityUser user = await userManager.GetUserAsync(context.User);

        if(signInManager.IsSignedIn(context.User))
        {
            await signInManager.RefreshSignInAsync(user);
        }
    }
}

然后在您的控制器中使用它

Then use it in your controller

[HttpPost("[action]")]
[Authorize]
public async Task<IActionResult> Validate()
{
    await HttpContext.RefreshLoginAsync();
}

或在动作过滤器中对其进行抽象

Or abstract it in an action filter

public class RefreshLoginAttribute : ActionFilterAttribute
{
    public override async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
    {
        await context.HttpContext.RefreshLoginAsync();

        await next();
    }
}

然后在控制器中像这样使用它

Then use it like this in your controller

[HttpPost("[action]")]
[Authorize]
[RefreshLogin] // or simpler [Authorize, RefreshLogin]
public async Task<IActionResult> Validate()
{
    // your normal controller code
}
