身份用户自定义属性的实现获取/设置方法

Question

我正在使用Identity，并使用三个自定义属性扩展了基本IdentityUser。使用.netCore 3.1.1和身份4

namespace FleetLogix.Intranet.Identity
{
    // Add profile data for application users by adding properties to the ApplicationUser class
    public class ApplicationUser : IdentityUser<int>
    {
        [MaxLength(50)]
        [PersonalData]
        public string FirstName { get; set; }

        [MaxLength(50)]
        [PersonalData]
        public string LastName { get; set; }

        [MaxLength(5)]
        public string OrgCode { get; set; }

        public ApplicationUser() : base()
        {

        }


    }
}

这些是在[AspNetUsers]表中愉快创建的。已创建4个初始用户，并填充了所有其他属性。

我还创建了一些扩展名，这些扩展名使我可以获取这些属性的值。名字-> GivenName，姓氏->姓氏和组织代码是CustomClaimTypes.OrgCode

namespace FleetLogix.Intranet.Identity
{
    /// <summary>
    /// Extends the <see cref="System.Security.Principal.IIdentity" /> object to add accessors for our custom properties.
    /// </summary>
    public static class IdentityExtensions
    {
        /// <summary>
        /// Gets the value of the custom user property FirstName
        /// </summary>
        /// <example>
        /// User.Identity.GetFirstName()
        /// </example>
        /// <param name="identity">Usually the Identity of the current logged in User</param>
        /// <returns><see langword="string"/> containing value of LastName or an empty string</returns>
        public static string GetFirstName(this IIdentity identity)
        {
            ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
            Claim claim = claimsIdentity?.FindFirst(ClaimTypes.GivenName);

            return claim?.Value ?? string.Empty;
        }

        /// <summary>
        /// Gets the value of the custom user property LastName
        /// </summary>
        /// <example>
        /// User.Identity.GetLastName()
        /// </example>
        /// <param name="identity">Usually the Identity of the current logged in User</param>
        /// <returns><see langword="string"/> containing value of LastName or an empty string</returns>
        public static string GetLastName(this IIdentity identity)
        {
            ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
            Claim claim = claimsIdentity?.FindFirst(ClaimTypes.Surname);

            return claim?.Value ?? string.Empty;
        }


        /// <summary>
        /// Gets the value of the custom user property OrgCode
        /// </summary>
        /// <example>
        /// User.Identity.GetOrgCode()
        /// </example>
        /// <param name="identity">Usually the Identity of the current logged in User</param>
        /// <returns><see langword="string"/> containing value of OrgCode or an empty string</returns>
        public static string GetOrgCode(this IIdentity identity)
        {
            ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
            Claim claim = claimsIdentity?.FindFirst(CustomClaimTypes.OrgCode);

            return claim?.Value ?? string.Empty;
        }
    }
}

我正在建立一个新站点，并想要修改_LoginPartial.cshtml。我想用登录的名字替换登录用户名（电子邮件地址）的显示

@if (SignInManager.IsSignedIn(User))
{
    <li class="nav-item">
    <a id="manage" class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Hello @UserManager.GetUserName(User)!</a> 
    </li>
   ...
}

至此

@if (SignInManager.IsSignedIn(User))
{
    <li class="nav-item">
    <a id="manage" class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Hello @User.Identity.GetFirstName()!</a> 
    </li>
   ...
}

但是，这将导致文本为空。 为什么空白？

单击进入Account/Manage/Index页面，将显示一个用于修改用户详细信息的表格。我修改了InputModel使其包含两个自定义属性（FirstName，LastName）。 LoadAsync任务已被修改以加载值（使用扩展方法）并将其添加到“ InputModel”>

private async Task LoadAsync(ApplicationUser user)
{

    var userName = await _userManager.GetUserNameAsync(user);
    var phoneNumber = await _userManager.GetPhoneNumberAsync(user);
    var firstName =  user.FirstName;
    var lastName = user.LastName;
    var orgCode = user.OrgCode;


    Username = userName;

    OrgCode = orgCode;

    Input = new InputModel
    {
        PhoneNumber = phoneNumber,
        FirstName = firstName,
        LastName = lastName

    };
}

为什么自定义属性在此页面上可见，而在上一页却不可见？

Account/Manage/Index中的进一步更新方法OnPostAsync()

public async Task<IActionResult> OnPostAsync()
{
   var user = await _userManager.GetUserAsync(User);
   if (user == null)
   {
       return NotFound($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
   }

   if (!ModelState.IsValid)
   {
       await LoadAsync(user);
       return Page();
   }

   var phoneNumber = await _userManager.GetPhoneNumberAsync(user);
   if (Input.PhoneNumber != phoneNumber)
   {
       var setPhoneResult = await _userManager.SetPhoneNumberAsync(user, Input.PhoneNumber);
       if (!setPhoneResult.Succeeded)
       {
           var userId = await _userManager.GetUserIdAsync(user);
           throw new InvalidOperationException($"Unexpected error occurred setting phone number for user with ID '{userId}'.");
       }
   }

   var firstName = user.FirstName; //.GetPhoneNumberAsync(user);
   if (Input.FirstName != firstName)
   {
       //var setFirstNameResult = await _userManager.SetFirstNameAsync(user, Input.FirstName);
       user.FirstName = Input.FirstName;
       //if (!setFirstNameResult.Succeeded)
       //{
       //    var userId = await _userManager.GetUserIdAsync(user);
       //    throw new InvalidOperationException($"Unexpected error occurred setting First Name for user with ID '{userId}'.");
       //}
   }


   var lastName = user.LastName;
   if (Input.LastName != lastName)
   {
       //var setLastNameResult = await _userManager.SetLastNameAsync(user, Input.LastName);
       user.LastName = Input.LastName;
       //if (!setLastNameResult.Succeeded)
       //{
       //    var userId = await _userManager.GetUserIdAsync(user);
       //    throw new InvalidOperationException($"Unexpected error occurred setting Last Name for user with ID '{userId}'.");
       //}
   }

   await _signInManager.RefreshSignInAsync(user);
   StatusMessage = "Your profile has been updated";
   return RedirectToPage();
}
[没有SetPhoneNumberAsync()之类的Set方法，我尝试使用属性设置器。这没用。 如何更新身份用户自定义属性值？

我只想能够使用自定义的用户属性。我需要FirstName和OrgCode属性在他们登录后立即可用，当前情况并非如此。当前的扩展方法并不总是有效。

此外，如果它们是错误或更改的需求，我需要能够编辑这些属性。

您需要创建身份范围，只需创建您的身份并添加范围
