ASP.NET Core 5 Web API中的用户认证

Question

在 Web API 项目中，我使用以下方法登录我的用户，但稍后我想获取我的用户名和姓。 我正在使用 Web API 和 .NET 5。

public AuthenticateResponse Authenticate(AuthenticateRequest model, string ipAddress)
{
    var user = _userManager.Users
                           .Where(w => w.UserName == model.Username)
                           .FirstOrDefault();

    // This doesn't count login failures towards account lockout
    // To enable password failures to trigger account lockout, set 
    lockoutOnFailure: true

    var result = _signInManager.PasswordSignInAsync(model.Username, model.Password, true, lockoutOnFailure: false);

    User users = new User();
    users.Username = model.Username;
    users.Password = model.Password;
    users.FirstName = user.FirstName;
    users.LastName = user.LastName;

    if (result.Result.Succeeded)
    {
        // return null if user not found
        if (user == null)
            return null;
    }

    // authentication successful so generate jwt and refresh tokens
    var jwtToken = generateJwtToken(users);
    var refreshToken = generateRefreshToken(ipAddress);

    // save refresh token
    // users.RefreshTokens.Add(refreshToken);

    return new AuthenticateResponse(users, jwtToken, null);
 }

我在UserService class 中有这种方法，如何最好地访问来自

users.FirstName
users.LastName

来自 Web API controller 可以说是俱乐部。 如您所见，我正在使用登录管理器和用户管理器，我应该在我的ClubController中简单地加载一个实例。

我的 API 方法是

[HttpPost]
[Route("Clubs/Create")]
public async Task<IActionResult> Create(ClubViewModelApi clubModel)
{
    if (ModelState.IsValid)
    {
        Club _club = new Club();
        _club.Name = clubModel.Name;
        _club.Description = clubModel.Description;
        _club.isActive = clubModel.isActive;
        _club.isDeleted = clubModel.isDeleted;
        _club.CreatedDate = DateTime.Now;
        _club.CreatedBy = insert first lastname here;

        _club.CreatedBy = User.Identity.

        _context.Clubs.Add(_club);

        await _context.SaveChangesAsync();

        return Ok();
    }

    return View(clubModel);
}

我希望在上面的 api 端点的这一点处插入名字和姓氏_club.CreatedBy 。

我在进行身份验证时使用此代码创建我的令牌：

private string generateJwtToken(User user)
{
    var tokenHandler = new JwtSecurityTokenHandler();
    var secret = _configRoot.GetValue<string>("JWTSecret");

    _logger.Log(LogLevel.Information, $"JWT Secret from Everleap={secret}");

    var key = Encoding.ASCII.GetBytes(secret);
    var tokenDescriptor = new SecurityTokenDescriptor
                              {
                                  Subject = new ClaimsIdentity(new Claim[]
                                                {
                                                     new Claim(ClaimTypes.Name, user.Id.ToString())
                                                }),
                                  Expires = DateTime.UtcNow.AddMinutes(15),
                                  SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
                              };

    var token = tokenHandler.CreateToken(tokenDescriptor);

    return tokenHandler.WriteToken(token);
}

我的详细信息存储在 jwttoken 中。 我是否将 go 再次取出该令牌并在 controller 级别对其进行解密。

响应正文

{
   "id": 0,
   "firstName": "david",
   "lastName": "buckley",
   "username": "davidbuckleyweb@outlook.com",

我发现我需要做的是扩展我的声明，以便它自己存储在令牌中我使用以下代码对令牌进行编码

var tokenDescriptor = new SecurityTokenDescriptor
{    
     Subject = new ClaimsIdentity(new Claim[]
            {
                 new Claim("CreatedBy", user.FirstName.Substring(0,1).ToUpper() + " "  + user.LastName.Substring(0,1).ToUpper()),
                new Claim(ClaimTypes.Email, user.Username),
                new Claim(ClaimTypes.Name, user.FirstName + " " + user.LastName),
                new Claim(ClaimTypes.Role,roles)
            }),
            Expires = DateTime.UtcNow.AddMinutes(15),
            SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
        };

然后解码它我使用以下。

var authorization = Request.Headers[HeaderNames.Authorization];
if (AuthenticationHeaderValue.TryParse(authorization, out var headerValue))
{
    // we have a valid AuthenticationHeaderValue that has the following details:
     var scheme = headerValue.Scheme;
     var JWTToken = headerValue.Parameter;

     var token = new JwtSecurityToken(jwtEncodedString: JWTToken);
     string name = token.Claims.First(c => c.Type == "CreatedBy").Value;       
    _club.CreatedBy = name;
 }
