asp.net core 默认采用小驼峰命名和自定义模型验证

             services.AddMvc(options =>
             {
                 options.Filters.Add<ApiExceptionAttribute>();
             }).SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
              .AddJsonOptions(options =>
              {
                  options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver();//JSON首字母小写解决
                  options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
                  //返回Json属性命名默认按照小驼峰规则
                  options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
              });

             //参数验证
             services.Configure<ApiBehaviorOptions>(options =>
             {
                 options.InvalidModelStateResponseFactory = (context) =>
                 {
                     var error = context.ModelState.GetValidationSummary();

                     return new JsonResult(Result.FromError($"参数验证不通过：{error.ToString()}", ResultCode.InvalidParams));
                 };
             });
