JWT Bearer 不断返回 401 状态 - Bearer error="invalid_token", error_description="The signature is invalid"

Question

我在我的 Web API 中实现了 Jwt Bearer，我成功获得了登录令牌。我 copy/paste 这个令牌用于授权，我收到

Bearer error="invalid_token", error_description="The signature is invalid"

ValidIssuer 是 WebAPIUrl，部署在 Azure

ValidAudience 是 Angular 前端 URL，也部署在 Azure

我花了几个小时寻找问题，但似乎没有找到解决方案。

即使将 ValidateIssuer & -Audience 设置为 false，也无法解决问题。我是不是漏掉了什么或者你看到错误了吗？

Startup.cs

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors(options =>
            {
                options.AddPolicy("CorsPolicy", builder =>
                {
                    builder.AllowAnyOrigin()
                    .AllowAnyHeader()
                    .AllowAnyMethod();
                });
            });
            services.ConfigureIISIntegration();

            services.ConfigureMsSqlContext(Configuration);

            services.ConfigureRepositoryWrapper();

            services.AddAuthentication(opt => {
                opt.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                opt.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
                opt.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
            })
            .AddJwtBearer(options =>
            {
                options.SaveToken = true;
                options.RequireHttpsMetadata = false;
                options.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateIssuer = true,
                    ValidateAudience = true,
                    ValidIssuer = Configuration["JWT:Issuer"],
                    ValidAudience = Configuration["JWT:Audience"],
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["JWT:Secret"]))
                };
            });

            services.AddControllers();
        }

        
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseDeveloperExceptionPage();

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseCors("CorsPolicy");

            app.UseForwardedHeaders(new ForwardedHeadersOptions
            {
                ForwardedHeaders = ForwardedHeaders.All
            });

            app.UseAuthentication();
            app.UseRouting();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }

我的问题的解决方案，可能很小但很详细

我忘记将授权属性放在我的请求方法之上

[HttpGet, Authorize]
public IActionResult GetMaterialDetails()

JWT Bearer 不断返回 401 状态 - Bearer error="invalid_token", error_description="The signature is invalid"

JWT Bearer Keeps returning 401 Status - Bearer error="invalid_token", error_description="The signature is invalid"
