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));
                };
            });
