MissingFieldException:找不到字段:'Microsoft.Net.Http.Headers.HeaderNames.Authorization' [英] MissingFieldException: Field not found: 'Microsoft.Net.Http.Headers.HeaderNames.Authorization'
问题描述
我使用 .NET Core 3.0预览版4 CLI 制作了API.我想到了可以发送用户名和密码并获得令牌(JWT)的地步.
I making an API with .NET Core 3.0 Preview 4 CLI. I've came up to the point where you can send username and password and get the token (JWT).
这是我的登录方法.
[HttpPost("login")]
public async Task<IActionResult> Login([FromBody] UserForLoginDto userForRegisterDto)
{
var userFromRepo = await _repo.Login(userForRegisterDto.Username.ToLower(), userForRegisterDto.Password);
if (userFromRepo == null) //User login failed
return Unauthorized();
//generate token
var tokenHandler = new JwtSecurityTokenHandler();
var key = Encoding.ASCII.GetBytes(_config.GetSection("AppSettings:Token").Value);
var tokenDescriptor = new SecurityTokenDescriptor
{
Subject = new ClaimsIdentity(new Claim[]{
new Claim(ClaimTypes.NameIdentifier,userFromRepo.Id.ToString()),
new Claim(ClaimTypes.Name, userFromRepo.Username)
}),
Expires = DateTime.Now.AddDays(1),
SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha512Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
var tokenString = tokenHandler.WriteToken(token);
return Ok(new { tokenString });
}
此方法可以正常工作并为我提供令牌,但是我想使用[Authorize]
属性限制对方法或控制器的访问,因此出现以下异常.
This methods works fine and provide me the token, but I want to restrict access to a method or a controller using [Authorize]
attribute, I get the following exception.
MissingFieldException: Field not found: 'Microsoft.Net.Http.Headers.HeaderNames.Authorization'.
Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler.HandleAuthenticateAsync()
System.Runtime.CompilerServices.AsyncMethodBuilderCore.Start<TStateMachine>(ref TStateMachine stateMachine)
Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler.HandleAuthenticateAsync()
Microsoft.AspNetCore.Authentication.AuthenticationHandler<TOptions>.AuthenticateAsync()
Microsoft.AspNetCore.Authentication.AuthenticationService.AuthenticateAsync(HttpContext context, string scheme)
Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context)
Microsoft.AspNetCore.Routing.EndpointRoutingMiddleware.Invoke(HttpContext httpContext)
Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context)
我仅使用Authorization
标头发送请求.
I'm sending the request with Authorization
header only.
我已经在ConfigureServices
方法中配置了身份验证中间件,如下所示.
I have configured authentication middleware in ConfigureServices
method as follows.
public void ConfigureServices(IServiceCollection services)
{
services.AddCors();
services.AddDbContext<DataContext>(x => x.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddControllers()
.AddNewtonsoftJson();
services.AddScoped<IAuthRepository, AuthRepository>();
var key = Encoding.ASCII.GetBytes(Configuration.GetSection("AppSettings:Token").Value);
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options => {
options.TokenValidationParameters = new TokenValidationParameters{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(key),
ValidateIssuer = false,
ValidateAudience = false
};
});
}
,并且已将app.UseAuthentication();
添加到Configure
方法.
and have added app.UseAuthentication();
to Configure
method.
app.UseCors(x => x.AllowAnyHeader().AllowAnyMethod().AllowCredentials());
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
我拼命尝试安装以下具有0运气的软件包.
Desperately I have tried installing following packages with 0 luck.
dotnet添加软件包Microsoft.Net.Http.Headers --version 2.2.0
dotnet add package Microsoft.Net.Http.Headers --version 2.2.0
dotnet添加软件包Microsoft.AspNetCore.StaticFiles --version 2.2.0
dotnet add package Microsoft.AspNetCore.StaticFiles --version 2.2.0
我不知道出了什么问题.该代码曾经用于.NET Core 2.2
I have no idea what is going wrong. This code used to work with .NET Core 2.2
