Question

我已经基于教程实现了JWT身份验证/授权系统。

但是不幸的是，我不知道如何授权角色。

这是基于角色的授权。

    public class InfoController : ControllerBase
    {
        [Authorize(Roles = "User")]
        [HttpGet("user")]
        public IActionResult UserInfo()
        {
            return Ok("User role");
        }
    }

当我将其称为api/Info/user时，会收到 401 响应代码，而不是带有“用户角色”消息的状态代码 200 。因此，基于角色的授权不起作用。我用正确的数据称呼它：

curl -X GET "https://localhost:34545/api/Info/user" -H  "accept: application/json" -H  "Authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ0ZXN0IiwianRpIjoiYTgwYzQ3NDQtNmYyZC00ZTAwLThhYjItMzY2MTRmYTNmMzYzIiwiaWF0IjoxNTU3NjgyMDU4LCJyb2wiOiJ3ZWItYXBpLWFjYyIsImh0dHA6Ly9zY2hlbWFzLm1pY3Jvc29mdC5jb20vd3MvMjAwOC8wNi9pZGVudGl0eS9jbGFpbXMvcm9sZSI6IlVzZXIiLCJuYmYiOjE1NTc2ODIwNTgsImV4cCI6MTU1NzY4OTI1OCwiaXNzIjoid2ViLWFwaSIsImF1ZCI6Imh0dHBzOi8vbG9jYWxob3N0OjQ0MzUwLyJ9.8uRAOsSXmKeWcYCwvN0sNFX02GNoZMaPNf6RPGkQE4E"

在启动时，我具有以下配置：

services.AddAuthorization(options =>
        {
            options.AddPolicy("api", policy => policy.RequireClaim(
               jwtClaimConfiguration[nameof(JwtClaimOptions.Rol)],
               jwtClaimConfiguration[nameof(JwtClaimOptions.ApiAccess)]
            ));
            options.AddPolicy("user", policy => policy.RequireRole(AppRole.USER));
            options.AddPolicy("admin", policy => policy.RequireRole(AppRole.ADMIN));
        });

Jwt在这里生成（在这里我已经在StackOverflow上看到了这种解决方案）

 public async Task<string> GenerateEncodedTokenAsync(string userName, ClaimsIdentity claimsIdentity)
        {
            List<Claim> claims = new List<Claim>()
            {
                 new Claim(JwtRegisteredClaimNames.Sub, userName),
                 new Claim(JwtRegisteredClaimNames.Jti, await jwtOptions.JtiGenerator()),
                 new Claim(JwtRegisteredClaimNames.Iat, ToUnixEpochDate(jwtOptions.IssuedAt).ToString(), ClaimValueTypes.Integer64),
                 claimsIdentity.FindFirst(jwtClaimConfiguration[nameof(JwtClaimOptions.Rol)]),
                 claimsIdentity.FindFirst(jwtClaimConfiguration[nameof(JwtClaimOptions.ApiAccess)])
             };
            var user = await userManager.FindByNameAsync(userName);
            var roles = await userManager.GetRolesAsync(user);

            claims.AddRange(roles.Select(role => new Claim(ClaimsIdentity.DefaultRoleClaimType, role)));

            JwtSecurityToken jwt = new JwtSecurityToken(
                issuer: jwtOptions.Issuer,
                audience: jwtOptions.Audience,
                notBefore: jwtOptions.NotBefore,
                expires: jwtOptions.Expiration,
                signingCredentials: jwtOptions.SigningCredentials,
                claims: claims
            );

            return new JwtSecurityTokenHandler().WriteToken(jwt);
        }

Jwt令牌包含角色！这是有效负载，如您所见，已添加了角色，用户具有“用户”角色。

{
  "sub": "demo",
  "jti": "a80c4744-6f2d-4e00-8ab2-36614fa3f363",
  "iat": 1557682058,
  "rol": "acc",
  "http://schemas.microsoft.com/ws/2008/06/identity/claims/role": "User",
  "nbf": 1557682058,
  "exp": 1557689258,
  "iss": "api",
  "aud": "https://localhost:34545/"
}

ASP.NET Core WebApi Jwt基于角色的授权不起作用
