webApi-配置json和xml格式及时间格式

在config文件中修改如下代码：

 //添加全局异常过滤器
            config.Filters.Add(new ErrorFilterAttribute());
            //设置xml格式器---用于屏蔽字典类型xml序列化错误
            var xml = config.Formatters.XmlFormatter;
            xml.UseXmlSerializer = true;

            用于处理json 格式化实体类带有   [Serializable]混乱
            var serializerSettings =
                 config.Formatters.JsonFormatter.SerializerSettings;
            var contractResolver =
              (DefaultContractResolver)serializerSettings.ContractResolver;
            contractResolver.IgnoreSerializableAttribute = true;
            //对日期json格式化
            config.Formatters.JsonFormatter.SerializerSettings.Converters.Add(
              new Newtonsoft.Json.Converters.IsoDateTimeConverter()
              {
                  DateTimeFormat = "yyyy/MM/dd HH:mm:ss"
              }
            );

            GlobalConfiguration.Configuration.AddJsonpFormatter();
            config.MessageHandlers.Add(new CustomMessageHandler());//兼容ie8原生跨域
