core JwtBearer

• 1、自定义认证中间件 JwtTokenAuth
• 2、Startup
• Configure下：

•  if (env.IsDevelopment())
              {
                  GlobalContext.SystemConfig.Debug = true;
                  app.UseDeveloperExceptionPage();
              }
              else
              {

              }
              app.UseCors("CorsPolicy");
              app.UseAuthentication();
              app.UseMiddleware<JwtTokenAuth>();
  
              string resource = Path.Combine(env.ContentRootPath, "Resource");
              FileHelper.CreateDirectory(resource);
  
              app.UseStaticFiles(new StaticFileOptions
              {
                  OnPrepareResponse = GlobalContext.SetCacheControl
              });
              app.UseStaticFiles(new StaticFileOptions
              {
                  RequestPath = "/Resource",
                  FileProvider = new PhysicalFileProvider(resource),
                  OnPrepareResponse = GlobalContext.SetCacheControl
              });
  
              app.UseMiddleware(typeof(GlobalExceptionMiddleware));
  
              app.UseCors(builder =>
              {
                  builder.WithOrigins(GlobalContext.SystemConfig.AllowCorsSite.Split(',')).AllowAnyHeader().AllowAnyMethod().AllowCredentials();
              });
              app.UseSwagger(c =>
              {
                  c.RouteTemplate = "api-doc/{documentName}/swagger.json";
              });
              app.UseSwaggerUI(c =>
              {
                  c.RoutePrefix = "api-doc";
                  c.SwaggerEndpoint("v1/swagger.json", "YiSha Api v1");
              });
              app.UseRouting();
  
              app.UseCors(cfg =>
              {
                  cfg.AllowAnyOrigin();
                  cfg.AllowAnyMethod(); 
                  cfg.AllowAnyHeader(); 
              });           
              app.UseAuthorization();
  
              app.UseEndpoints(endpoints =>
              {
                  endpoints.MapControllerRoute("default", "{controller=ApiHome}/{action=Index}/{id?}");
              });
              GlobalContext.ServiceProvider = app.ApplicationServices;
              if (!GlobalContext.SystemConfig.Debug)
              {
                  new JobCenter().Start(); // 定时任务
              }

  ConfigureServices下：

                     .AllowAnyHeader()
                     .AllowCredentials();
             }));   
              #endregion
  
              #region Swagger
              services.AddSwaggerGen(c =>

• 3、appsettings
  

  "Audience": {
      "Secret": "11111111111111",
      "Issuer": "222222222",
      "Audience": "Nobody"
    },

• 4、 Controller增加

• [ApiController]
  [ApiController][AuthorizeFilter]
  [Authorize]

• 5、AuthorizeFilter扩展

•  string token = context.HttpContext.Request.Headers["Authorization"].ParseToString();
              if (!string.IsNullOrEmpty(token))
              {
                  token =token.Replace("Bearer ", "");
              }

              OperatorInfo user = await Operator.Instance.Current(token);  
   if (user != null)
              {
                  // 根据传入的Token，设置CustomerId
                  if (context.ActionArguments != null && context.ActionArguments.Count > 0)
                  {

                      }
