[.Net]Framwork WebAPI添加接口请求监控

思路：
通过重写 ActionFilterAttribute 拦截Action的请求及返回信息，实现对接口请求的监听。
最终效果如下：
全局启用需配置如下：
局部启用需配置如下：
源码如下：
  1     /// <summary>
  2     /// 统一的接口访问监控日志，
  3     /// 全局启用-请添加 GlobalConfiguration.Configuration.Filters.Add(new TimingFilterAttribute());
  4     /// 局部启用（目前模式）-在Controller或者Action上添加Attribute注入即可
  5     /// </summary>
  6     public class TimingFilterAttribute : ActionFilterAttribute
  7     {
  8         private const string Key = "__action_recordtime__";
  9         private const string TimeKey = "__action_receivetime__";

 11         /// 自定义参数
 12         /// </summary>
