用MVC6写webapi，添加model校验过滤器

需求：过滤验证实体

实体code：

[StringLength(32, MinimumLength = 1, ErrorMessage = "{0} must be a string.  Its min length is {2}, its max length is {1}.")]

[Required]

publicstringOrderID {get;set; }

过滤器代码(这里会直接抛出错误信息)

 publicclassValidateModelStateFilter:ActionFilterAttribute

    {

       publicoverridevoidOnActionExecuted(ActionExecutedContextcontext)

        {

           if(!context.ModelState.IsValid)

            {

                context.Result =newBadRequestObjectResult(context.ModelState);

            }

        }

    }

过滤器注入代码

 publicvoidConfigureServices(IServiceCollectionservices)

        {

           // Add framework services.

            services.AddApplicationInsightsTelemetry(Configuration);

            services.AddMvc(options =>

            {

                options.Filters.Add(newValidateModelStateFilter());

            });

                     services.AddSingleton<IOrderRepo,OrderRepo>();

                     services.AddSwaggerGen();

                     services.ConfigureSwaggerGen(options =>

                     {

                           options.SingleApiVersion(newInfo

                           {

                                  Version ="v1",

                                  Title ="Zebra VMI Api",

                                  Description ="Zebra VMI Api by @360Zebra",

                                  TermsOfService ="NA",

                                  Contact =newContact()

                                  {

                                         Name ="斑马小二",

                                         Email ="[e-mail]",

                                         Url ="http://www.360zebra.com"

                                  }

                           });

                     });

              }
