JWT 令牌身份验证失败并显示消息“PII 已隐藏" [英] JWT token authentication fails with message "PII is hidden"

问题描述

在我的 .net core 2.2 微服务中，我尝试从 JWT 令牌中提取声明以进行一些授权.身份验证是在系统的另一部分完成的，所以我现在不需要这样做.

in my .net core 2.2 microservice, I try to extract claims from a JWT token to do some authorization. authentication is done on another part of the system so I don't need to do it at this point.

我在 Startup.cs 中使用此代码:

I am using this code in the Startup.cs:

  services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
            .AddJwtBearer(options =>
            {
                var signingKey = Encoding.UTF8.GetBytes("SECRET_KEY");
                options.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateIssuer = false,
                    ValidateAudience = false,
                    IssuerSigningKey = new SymmetricSecurityKey(signingKey)
                };
            });

在控制器上我有这个代码:

On the controller I have this code:

    [Authorize]
    [HttpPost]
    public async Task<ActionResult<CreateResponse>> Create()
    {
        var userIdClaim = HttpContext.User.Claims.Where(x => x.Type == "empId").SingleOrDefault();
        return Ok($"Your User ID is {userIdClaim.Value} and you can create invoices!");
    }

我总是收到此错误消息和未经授权"的响应:

I always get this error message and "Unauthorized" response:

Microsoft.IdentityModel.Tokens.SecurityTokenInvalidSignatureException:IDX10503:签名验证失败.尝试的键:'[PII 被隐藏]'.捕获的异常:'[PII 被隐藏]'.token: '[PII is hidden]'.

Microsoft.IdentityModel.Tokens.SecurityTokenInvalidSignatureException: IDX10503: Signature validation failed. Keys tried: '[PII is hidden]'. Exceptions caught: '[PII is hidden]'. token: '[PII is hidden]'.

推荐答案

在Startup类的Configure()中加入如下代码可以看到开发中隐藏的细节:

You can see the hidden details in development by adding the following to Configure() in the Startup class:

if (env.IsDevelopment())
{
     IdentityModelEventSource.ShowPII = true; 
}

收到完整消息后，请检查所使用的密钥对于令牌是否正确.

Once you have the full message check the key being used is correct for the token.
