mvc全局时间输出格式化处理

Global文件中：

            var formatters = GlobalConfiguration.Configuration.Formatters;
            var jsonFormatter = formatters.JsonFormatter;
            var settings = jsonFormatter.SerializerSettings;
            settings.Formatting = Newtonsoft.Json.Formatting.Indented;
            settings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
            settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
