Mongodb 重写UserClaimsPrincipalFactory generateclaimsasync方法不会'；不要让主张坚持下去

我已覆盖userclaimsprincipalfactory，如下所示：

 public class CustomClaimsPrincipalFactory : UserClaimsPrincipalFactory<User, Role>
{
    public CustomClaimsPrincipalFactory(UserManager<User> userManager, RoleManager<Role> roleManager,
        IOptions<IdentityOptions> optionsAccessor)
        : base(userManager, roleManager, optionsAccessor)
    {
    }

    protected override async Task<ClaimsIdentity> GenerateClaimsAsync(User user)
    {
        var id = await base.GenerateClaimsAsync(user);
        id.AddClaim(new Claim(ClaimTypes.Email, user.Email));

        return id;
    }
}

 services.AddIdentityMongoDbProvider<User, Role>(identityOptions =>
        {
            identityOptions.Password.RequiredLength = 6;
            identityOptions.Password.RequireLowercase = false;
            identityOptions.Password.RequireUppercase = false;
            identityOptions.Password.RequireNonAlphanumeric = false;
            identityOptions.Password.RequireDigit = false;
        }, mongoIdentityOptions => {
            mongoIdentityOptions.ConnectionString = configuration["Data:DefaultConnection:ConnectionString"];
        }).AddClaimsPrincipalFactory<CustomClaimsPrincipalFactory>();

这里的用户是ClaimsPrincipal类型，对象看起来像我添加声明的对象，但该对象中的任何位置都没有声明

这是我用来签名的代码：

 public async Task<UserDto> Login(LoginDataContract dataContract)
    {
        var appUser = userManager.Users.SingleOrDefault(s => s.Email == dataContract.Email);

        var result = await signInManager.PasswordSignInAsync(dataContract.Email, dataContract.Password, false, false);
        if (result.Succeeded)
        {
            var jwtObject = AuthenticationHelper.GenerateJwtToken(dataContract.Email, appUser, appSettings);

            var userDto = mapper.Map<User, UserDto>(appUser);

            userDto.Token = jwtObject.token;
            userDto.TokenExpiresIn = jwtObject.expiresIn;
            return userDto;
        }

        throw new Exception("Failed to login!");
    }

公共异步任务登录（LoginDataContract）
{
var appUser=userManager.Users.SingleOrDefault（s=>s.Email==dataContract.Email）；
var result=await-signInManager.PasswordSignInAsync（dataContract.Email，dataContract.Password，false，false）；
if（result.successed）
{
var jwtObject=AuthenticationHelper.GenerateJwtToken（dataContract.Email、appUser、appSettings）；
var userDto=mapper.Map（appUser）；
userDto.Token=jwtObject.Token；
userDto.TokenExpiresIn=jwtObject.expiresIn；
返回userDto；
}
抛出新异常（“登录失败！”）；
}

为什么索赔不能保留？

是的，很抱歉这是另一次尝试使用自定义索赔。我把它从问题中删除了

 public async Task<UserDto> Login(LoginDataContract dataContract)
    {
        var appUser = userManager.Users.SingleOrDefault(s => s.Email == dataContract.Email);

        var result = await signInManager.PasswordSignInAsync(dataContract.Email, dataContract.Password, false, false);
        if (result.Succeeded)
        {
            var jwtObject = AuthenticationHelper.GenerateJwtToken(dataContract.Email, appUser, appSettings);

            var userDto = mapper.Map<User, UserDto>(appUser);

            userDto.Token = jwtObject.token;
            userDto.TokenExpiresIn = jwtObject.expiresIn;
            return userDto;
        }

        throw new Exception("Failed to login!");
    }
