abp vnext 扩展 ICurrentUser，登录时增加C

1. 在项目 XXX.Main.Domain中新建 MyUserClaimsPrincipalFactory

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(AbpUserClaimsPrincipalFactory))] // 替换旧的AbpUserClaimsPrincipalFactory
public class MyUserClaimsPrincipalFactory : AbpUserClaimsPrincipalFactory, IScopedDependency
{
    public MainUserClaimsPrincipalFactory(UserManager<IdentityUser> userManager, 
        RoleManager<IdentityRole> roleManager, IOptions<IdentityOptions> options) : 
        base(userManager, roleManager, options)
    {
    }

    public override async Task<ClaimsPrincipal> CreateAsync(IdentityUser user)
    {
        var principal = await base.CreateAsync(user);
        var identityPrincipal = principal.Identities.First();
        /// add custom claim
        /// identityPrincipal.AddClaim(new Claim(XXX, XXX));

        return principal;
    }
}

2. 添加ApiResource

//一般在IdentityServerDataSeedContributor.cs中 添加
private async Task CreateApiResourcesAsync()
{
......
}

3. 用的时候

currentUser.FindClaimValue<类型>(ClaimTypes)
