ASP.Net Core JWT令牌验证

Question

我需要验证在请求中收到的多个令牌，我遵循以下代码流

services.AddAuthentication()
    .AddJwtBearer("Token1", options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters()
        {
            ValidateIssuer = true,
            ValidIssuer = Issuer,
            ValidateAudience = true,
            ValidAudience = Audience,
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Key)),
        };
        options.Events = new JwtBearerEvents()
        {
            OnMessageReceived = context =>
            {
                var Token = context.Request.Headers["UserCred1"].ToString();
                context.Token = Token;
                return Task.CompletedTask;
            },
        };
    })
    .AddJwtBearer("Token2", options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters()
        {
            ValidateIssuer = true,
            ValidIssuer = Issuer,
            ValidateAudience = true,
            ValidAudience = Audience,
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Key)),
        };
        options.Events = new JwtBearerEvents()
        {
            OnMessageReceived = context =>
            {
                var Token = context.Request.Headers["UserCred2"].ToString();
                context.Token = Token;
                return Task.CompletedTask;
            },
        };
    });
services.AddAuthorization(options =>
{
    options.DefaultPolicy = new AuthorizationPolicyBuilder()
    .RequireAuthenticatedUser()
    .AddAuthenticationSchemes("Token1", "Token2")
    .Build();
});

上面的代码用作OR条件，就像Token1或Token 2身份验证一样有效，然后返回为Success。但是对我来说，只有在“令牌1”和“令牌2”都有效时，我才需要考虑成功。

请让我知道您的想法。

services.AddAuthorization(options =>
        {
            options.AddPolicy("RequireAllSchemes", policy =>
            {
                policy.AddAuthenticationSchemes("Token1");
                policy.AddAuthenticationSchemes("Token2");
                policy.RequireAuthenticatedUser();
                policy.RequireAssertion(context =>
                {
                    return context.User.Identities.Count() == 2;
                });
            });
        });

指定控制器的授权策略

[Authorize（Policy =“ RequireAllSchemes”）]公共类TestController：控制器
