如何獲取Rally WS API調用的響應數據

Question

我想使用Rally .NET REST來測量API調用返回數據所花費的時間。 API是否有辦法輸出請求和響應數據，包括響應時間？

Answer 1

一個快速的方法來測量時間進行調用，然後調用後保存DateTime.Now，減去第二次的第一個值，並在打印之前保存DateTime.Now值：

DateTime startTime = DateTime.Now; 
    storyRequest.Query = new Query("FormattedID", Query.Operator.Equals, "US123"); 
    QueryResult queryStoryResults = restApi.Query(storyRequest); 
    Console.WriteLine(DateTime.Now.Subtract(startTime).ToString()); 

也可以打印請求和響應數據。當進行通話時，會收集通話數據，但您需要通過擴展System.Diagnostics.TraceListener來監聽。

下面是完整的代碼示例，其中時間以小數秒形式返回：ss.fffffff。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using Rally.RestApi; 
using Rally.RestApi.Response; 
using System.Diagnostics; 

namespace RESTexample_FindStories 
{ 
    class Program 
    { 

     class MyListener : TraceListener 
     { 

      public MyListener(): base(){} 

      public override void TraceEvent(TraceEventCache cache, String source, TraceEventType eventType, Int32 eventId, String msg) 
      { 
       TraceEvent(cache, source, eventType, eventId, msg, new Object[] { }); 
      } 

      public override void TraceEvent(TraceEventCache cache, String source, TraceEventType eventType, Int32 eventId, String msg, Object[] msgParams) 
      { 
       writeToEventLog(msg, msgParams, eventType); 
      } 

      public override void Write(string message) 
      { 
       WriteLine(message); 
      } 

      public override void WriteLine(string message) 
      { 
       writeToEventLog(message, new Object[] { }, TraceEventType.Information); 
      } 

      private void writeToEventLog(String msg, Object[] msgParams, TraceEventType eventType) 
      { 
       System.Console.WriteLine(msg, msgParams); 
      } 
     } 

     static void Main(string[] args) 
     { 
      Trace.Listeners.Add(new MyListener()); 

      RallyRestApi restApi; 
      restApi = new RallyRestApi("nmusaelian@rallydev.com", "Rally2013!", "https://rally1.rallydev.com", "v2.0"); 
      String projectRef = "/project/2222"; 

      Request storyRequest = new Request("hierarchicalrequirement"); 
      storyRequest.Project = projectRef; 

      storyRequest.Fetch = new List<string>() 
       { 
        "FormattedID" 
       }; 

      DateTime startTime = DateTime.Now; 
      storyRequest.Query = new Query("FormattedID", Query.Operator.Equals, "US123"); 
      QueryResult queryStoryResults = restApi.Query(storyRequest); 
      Console.WriteLine(DateTime.Now.Subtract(startTime).ToString()); 

      foreach (var s in queryStoryResults.Results) 
      { 
       Console.WriteLine("FormattedID: " + s["FormattedID"]); 

      } 

     } 
    } 
}
