invalid_token -- 未找到签名密钥

Question

我正在将令牌从 UI 存储库传递到后端。

export class AccountService {
  constructor(private http: HttpClient,  private oidcSecurityService: OidcSecurityService) {}
.
.
.
 const options = {
      headers: new HttpHeaders({
        Authorization: 'Bearer ' + token,
        'Content-Type': 'application/json',
      }),
    };
    debugger;
    return this.http.get<IRetrieveAccountSummaryResponse>(
      AppConfig.settings.businessUrl + '/api/account/AccountSummary/' + loanNumber,
      options
    );

在API包中，我在Startup.cs中添加了以下代码

  services.AddAuthentication("Bearer")
           .AddJwtBearer("Bearer", options =>
           {
               options.Authority = Configuration[AuthServiceEndpoint];

               options.TokenValidationParameters = new TokenValidationParameters
               {
                   ValidateIssuerSigningKey = true,
                   ValidateIssuer = false,
                   ValidateAudience = false
               };
           });
            services
                    .AddAuthorization(options =>
                    {
                        options.DefaultPolicy = new AuthorizationPolicyBuilder()
                            .RequireAuthenticatedUser()
                            .AddAuthenticationSchemes("Bearer")
                            .Build();
                    });

            app.UseAuthentication();
            app.UseAuthorization();

当我尝试加载页面时，出现 401 错误。当我检查“网络”选项卡时，它说

www-authenticate：承载错误=“invalid_token”，error_description=“未找到签名密钥”

在请求标头下，我可以看到

授权：承载 eyJhbGciOiJSUzI1N.......

我不确定在这种情况下什么是不正确的。

承载错误 - invalid_token - 找不到签名密钥 这对我没有帮助。
