ASP.NET Core 2.1 Jwt设置自定义声明 [英] ASP.NET Core 2.1 Jwt setting custom claims

问题描述

我有应该为用户设置声明的这段代码.当我使用身份和默认登录名时，它可以正常工作.但是，当我在另一个应用程序中使用jwt作为身份验证时，我没有ApplicationUser，因为我的ApplicationUser存储在对用户进行身份验证的另一个应用程序中.如何自定义此代码，使其与jwt一起使用?

I have this code that is supposed to set claims for a user. It works fine when I use identity and the default login. However, when I use jwt as authentication in another application, I don't have ApplicationUser as my ApplicationUser is stored in the other application that authenticates the user. How can I customize this code so that it works with jwt?

private readonly SignInManager<TIdentityUser> _signInManager;

public CustomClaimsCookieSignInHelper(SignInManager<TIdentityUser> signInManager)
{
    _signInManager = signInManager;
}

public async Task SignInUserAsync(TIdentityUser user, bool isPersistent, IEnumerable<Claim> customClaims)
{
    var claimsPrincipal = await _signInManager.CreateUserPrincipalAsync(user);
    var identity = claimsPrincipal.Identity as ClaimsIdentity;
    var claims = (from c in claimsPrincipal.Claims select c).ToList();
    var savedClaims = claims;
    if (customClaims != null)
    {
        identity.AddClaims(customClaims);
    }
    await _signInManager.Context.SignInAsync(IdentityConstants.ApplicationScheme,
        claimsPrincipal,
        new AuthenticationProperties { IsPersistent = isPersistent });
}

我想我的主要目的是在httpcontext中而不是在cookie中设置我的用户声明，而我想在不使用身份的情况下做到这一点.

I guess my main intention is to set my users claims in the httpcontext and not in a cookie and I want to do that without using identity.

我的应用程序结构

AuthenticationApp(服务器)

AuthenticationApp (server)

• 负责验证用户
• 生成并解码Jwt
• 检查用户是否具有适当的角色，并通过rest api返回true/false

MainApp(客户端)

MainApp (client)

• 对AuthenticationApp进行api调用
• 完全不使用身份
• 每次需要检查用户角色时都发送Jwt

我知道我将能够解码jwt客户端.但是，我不知道在哪里可以存储已解码的jwt详细信息，以便可以在视图中使用它.我最初的想法是像使用用户身份的普通应用程序一样使用Httpcontext.但是，我坚持上面的代码.

I understand that I will be able to decode the jwt client side. However, I do not know where I can store the decoded jwt details so that I can use it in the view. My initial idea was to use Httpcontext like normal applications that user Identity. However, I am stuck with the code above.

推荐答案

要在Controller和View之间共享身份信息，可以通过HttpContext.SignInAsync签名用户信息.

For sharing the Identity information between Controller and View, you could sign the User information by HttpContext.SignInAsync.

请尝试以下步骤来满足您的要求:

Try steps below to achieve your requirement:

• 控制器操作

• Controller Action

    public async Task<IActionResult> Index()
{
    var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme, ClaimTypes.Name, ClaimTypes.Role);
    identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, "edward"));
    identity.AddClaim(new Claim(ClaimTypes.Name, "edward zhou"));
    //add your own claims from jwt token
    var principal = new ClaimsPrincipal(identity);
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, new AuthenticationProperties { IsPersistent = true });            
    return View();
}

查看

View

@foreach (var item in Context.User.Claims)
{
   <p>@item.Value</p> 
};

要使上述代码生效，请在Startup.cs

public class Startup
{
public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

public IConfiguration Configuration { get; }

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{   
     //your rest code     


     services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    //your rest code
    app.UseAuthentication();
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

}
