WebApi关于配置全局返回Json数据格式时间以及命名小写

1.直接在Global文件中配置：

  1 var formatters = GlobalConfiguration.Configuration.Formatters;
  2 var jsonFormatter = formatters.JsonFormatter;
  3 var settings = jsonFormatter.SerializerSettings;

  2config.Formatters.XmlFormatter.MediaTypeMappings.Add(new QueryStringMapping("format", "xml", "application/xml"));
