经过大量阅读,我找到了一些答案以及可行的解决方案。
HTTP 标头
获得令牌后,需要保留令牌才能访问系统。使用 HTTP 标头存储令牌不会持续存在,因为 HTTP 协议 1.0 和 1.1 和 1.2 将在某个时候关闭 TCP 套接字以及它所具有的状态,即令牌。不适合您不控制 Http 连接的 WebClients,但可以用于移动开发、Android 或 IOS,如果您可以控制 HttpHeaders。
本地存储
您可以使用浏览器 localStorage 或 sessionStorage,但这些浏览器存在一些安全风险,JavaScript 可以读取这些值 - XSS 攻击。
饼干
另一种选择是将令牌存储在 Cookie 中; cookie 将与每个 http 请求一起传递,客户端没有什么特别的需要发生。这种方法不易受到 XSS 攻击。但是很容易出现CSRF。但是 CORS 再次可以帮助解决这个问题。
最好将 Cookie 设置为 HttpOnly,这样 cookie 将仅通过 HTTPS 传递。 Read more here
这是我根据我找到的一篇文章实现的

Startup.cs 配置服务...
// openssl rand -hex 16 => 32 bytes when read
var jwt_key = Configuration.GetSection("JwtOption:IssuerSigningKey").Value;
var signingKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(jwt_key));
var tokenValidationParameters = new TokenValidationParameters
{
// The signing key must match!
ValidateIssuerSigningKey = true,
IssuerSigningKey = signingKey,
// Validate the JWT Issuer (iss) claim
ValidateIssuer = true,
ValidIssuer = "some uri",
// Validate the JWT Audience (aud) claim
ValidateAudience = true,
ValidAudience = "the web",
// Validate the token expiry
ValidateLifetime = true,
// If you want to allow a certain amount of clock drift, set that here:
ClockSkew = TimeSpan.Zero
};
services.AddSingleton(tokenValidationParameters);
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie(options =>
{
int minute = 60;
int hour = minute * 60;
int day = hour * 24;
int week = day * 7;
int year = 365 * day;
options.LoginPath = "/auth/login";
options.AccessDeniedPath = "/auth/accessdenied";
options.Cookie.IsEssential = true;
options.SlidingExpiration = true;
options.ExpireTimeSpan = TimeSpan.FromSeconds(day/2);
options.Cookie.Name = "access_token";
options.TicketDataFormat = new CustomJwtDataFormat(
SecurityAlgorithms.HmacSha256,
tokenValidationParameters);
});
CustomJwtDataFormat 这将验证我们的令牌。
public class CustomJwtDataFormat :ISecureDataFormat<AuthenticationTicket>
{
private readonly string algorithm;
private readonly TokenValidationParameters validationParameters;
public CustomJwtDataFormat(string algorithm, TokenValidationParameters validationParameters)
{
this.algorithm = algorithm;
this.validationParameters = validationParameters;
}
public AuthenticationTicket Unprotect(string protectedText)
=> Unprotect(protectedText, null);
public AuthenticationTicket Unprotect(string protectedText, string purpose)
{
var handler = new JwtSecurityTokenHandler();
ClaimsPrincipal principal = null;
SecurityToken validToken = null;
try
{
principal = handler.ValidateToken(protectedText, this.validationParameters, out validToken);
var validJwt = validToken as JwtSecurityToken;
if (validJwt == null)
{
throw new ArgumentException("Invalid JWT");
}
if (!validJwt.Header.Alg.Equals(algorithm, StringComparison.Ordinal))
{
throw new ArgumentException($"Algorithm must be '{algorithm}'");
}
// Additional custom validation of JWT claims here (if any)
}
catch (SecurityTokenValidationException e)
{
System.Console.WriteLine(e);
return null;
}
catch (ArgumentException e)
{
System.Console.WriteLine(e);
return null;
}
// Validation passed. Return a valid AuthenticationTicket:
return new AuthenticationTicket(principal, new AuthenticationProperties(), "Cookie");
}
// This ISecureDataFormat implementation is decode-only
public string Protect(AuthenticationTicket data)
{
throw new NotImplementedException();
}
public string Protect(AuthenticationTicket data, string purpose)
{
throw new NotImplementedException();
}
}
LoginController验证用户名和密码后,调用SignInUser
private string GenerateSecurityToken(List<Claim> claims)
{
var tokenHandler = new JwtSecurityTokenHandler();
var expire = System.DateTime.UtcNow.AddMinutes(userService.GetJwtExpireDate());
var tokenDescriptor = new SecurityTokenDescriptor
{
Subject = new ClaimsIdentity(claims),
Expires = expire,
SigningCredentials = new SigningCredentials(tokenValidationParameters.IssuerSigningKey, SecurityAlgorithms.HmacSha256Signature),
Audience = tokenValidationParameters.ValidAudience,
Issuer = tokenValidationParameters.ValidIssuer
};
var token = tokenHandler.CreateToken(tokenDescriptor);
return tokenHandler.WriteToken(token);
}
private async Task<List<Claim>> GetClaims(UserModel user) {
var claims = new List<Claim>
{
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Email),
new Claim(ClaimTypes.Email, user.Email),
};
// add roles
var roleList = await userService.UserRoles(user.Email);
foreach (var role in roleList)
{
var claim = new Claim(ClaimTypes.Role, role.Role);
claims.Add(claim);
}
return claims;
}
private async Task<IActionResult> SignInUser(UserModel user, bool rememberMe)
{
var claims = await GetClaims(user);
var token = GenerateSecurityToken(claims);
// return Ok(new { Token = token });
// HttpContext.Request.Headers.Add("Authorization", $"Bearer {token}");
// HttpContext.Response.Cookies.Append(
HttpContext.Response.Cookies.Append("access_token", token, new CookieOptions { HttpOnly = true, Secure = true });
return RedirectToAction("Index", "Home", new { area = "" });
