Я пытаюсь использовать защиту от подделки вместе с аутентификацией на носителе jwt в веб-API ядра 3.0 Asp.net. Странная проблема, с которой я сталкиваюсь, заключается в том, что защита от подделки работает отлично, но если я попытаюсь добавить фильтр [Authorize]
к действию контроллера вместе с [ValidateAntiForgeryToken]
, тогда проверка AntiForgery
завершится неудачно с ошибкой Http 400.
startup.cs:
services.AddCors();
services.AddControllers();
services.AddMvc();
services.AddAntiforgery
(
options =>
{
options.HeaderName = "X-XSRF-TOKEN";
options.Cookie = new Microsoft.AspNetCore.Http.CookieBuilder()
{ Name = "X-XSRF-COOKIE" };
}
);
// configure strongly typed settings objects
var appSettingsSection = Configuration.GetSection("AppSettings");
services.Configure<AppSettings>(appSettingsSection);
// configure jwt authentication
var appSettings = appSettingsSection.Get<AppSettings>();
var key = Encoding.ASCII.GetBytes(appSettings.Secret);
services.AddAuthentication(x =>
{
x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(x =>
{
x.RequireHttpsMetadata = false;
x.SaveToken = true;
x.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(key),
ValidateIssuer = false,
ValidateAudience = false
};
});
UsersController.cs:
[AllowAnonymous]
[IgnoreAntiforgeryToken]
[HttpPost("authenticate")]
public IActionResult Authenticate([FromBody]AuthenticateModel model)
{
var user = _userService.Authenticate(model.Username, model.Password);
var tokens = _antiforgery.GetAndStoreTokens(HttpContext);
Response.Cookies.Append("X-XSRF-TOKEN", tokens.RequestToken, new Microsoft.AspNetCore.Http.CookieOptions
{
HttpOnly = false
});
if (user == null)
return BadRequest(new { message = "Username or password is incorrect" });
return Ok(user);
}
Если я использую фильтр [Authorize]
для указанного ниже действия, Antiforgery
проверка не пройдена. Если удалитьэто Antiforgery
проверка работает нормально.
UsersController.cs:
[HttpGet]
[Authorize]
[ValidateAntiForgeryToken]
public IActionResult GetAll()
{
var users = _userService.GetAll();
return Ok(users);
}
и вот как я генерирую токен JWT:
var tokenHandler = new JwtSecurityTokenHandler();
var key = Encoding.ASCII.GetBytes(_appSettings.Secret);
var tokenDescriptor = new SecurityTokenDescriptor
{
Expires = DateTime.UtcNow.AddDays(7),
SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key),
SecurityAlgorithms.HmacSha256Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
user.Token = tokenHandler.WriteToken(token);

Пробовал установить HttpContext.user

, но это не сработало.
