Httpwatch是一款强大的网页数据分析工具,它可以在不改变浏览器和网络设置的基础上捕捉http和https数据。查看底层的http数据,包括headers, cookies, cache等,同时统计发送接收请求时间,并提供完备的日志记录系统。同时该工具具有完备的COM接口,用于给用户通过编程的方式操纵httpwatch.

Httpwatch 自动化对象介绍:

Controller 类:总是控制的起点,它用于创建httpwatch插件接口或读取log文件,通过IE属性和Firefox属性的new()方法或者Attach()方法返回Plugin实例对象。

Plugin 类:是httpwatch与浏览器交互的接口。提供了方法用于开始和停止http流量的记录,还有很多方法和属性管理httpwatch的日志文件和配置自动化记录。

Log 类: Plugin对象的Log属性是Log对象的入口。包含了一系列通过httpwatch记录的日志。Log对象中具有很多重要的类,比如Pages, Entries类。

Entry 类: 每个Log对象都包含一组Entry对象,它代表的是单个HTTP事务的详情(比如http请求)

通过 WatiN和httpwatch结合进行自动化测试,可以很大程度扩展自动化测试的范围,比如在自动化测试过程中验证链接的连通性,网页传输速率和时间,查看网页的详细信息等。

C#操作httpwatch

  1. 添加httpwatch自动化类库到项目中
  2. 创建与httpwatch工具的联系

    创建新的IE接口:顶部添加引用  using HttpWatch;

技术分享
1             Controller control = new Controller();
2             Plugin plugin = control.IE.New();
View Code

    创建新的Firefox接口:

技术分享
1             Controller control = new Controller();
2             Plugin plugin = control.Firefox.New();
View Code

    附加一个已存在的IE窗口:

技术分享
1             SHDocVw.IWebBrowser2 ieBrowser = new SHDocVw.InternetExplorer();
2             ieBrowser.Visible = true;  //Required to see new window
3             Controller control = new Controller();
4             Plugin plugin = control.IE.Attach(ieBrowser);
View Code

    附加一个已存在的Firefox窗口:

技术分享
1             Controller control = new Controller();
2             Plugin plugin = control.Firefox.Attach(firefoxBrowser);
View Code

  3. 通过接口读取http详细信息

Example:

技术分享
 1         public static HttpWatchInfo RunHttpWatch(string url)
 2         {
 3             Controller control = new Controller();
 4             Plugin plugin = control.IE.New();
 5 
 6             plugin.Log.EnableFilter(false);
 7             plugin.Record();
 8             plugin.GotoURL(url);
 9             control.Wait(plugin, -1);
10             plugin.Stop();
11 
12             HttpWatchInfo httpWatchSummary = new HttpWatchInfo();
13             if (plugin.Log.Pages.Count != 0)
14             {
15                 Summary summary = plugin.Log.Pages[0].Entries.Summary;
16                 httpWatchSummary.URL = url;
17                 httpWatchSummary.Time = summary.Time;
18                 httpWatchSummary.RoundTrips = summary.RoundTrips;
19                 httpWatchSummary.BytesReceived = summary.BytesReceived;
20                 httpWatchSummary.BytesSent = summary.BytesSent;
21                 httpWatchSummary.CompressionSavedBytes = summary.CompressionSavedBytes;
22 
23                 IList<string> codes = new List<string>();
24                 for (int i = 0; i < summary.StatusCodes.Count; i++)
25                     codes.Add(summary.StatusCodes[i].Result);
26                 httpWatchSummary.StatusCode = codes;
27 
28                 IList<HttpWatchDetail> httpWatchDetail = new List<HttpWatchDetail>();
29                 for (int i = 0; i < plugin.Log.Entries.Count; i++)
30                 {
31                     HttpWatchDetail detail = new HttpWatchDetail();
32                     detail.URL = plugin.Log.Entries[i].URL;
33                     detail.Result = plugin.Log.Entries[i].Result;
34                     detail.Time = plugin.Log.Entries[i].Time.ToString();
35                     detail.Error = plugin.Log.Entries[i].Error;
36                     try
37                     {
38                         detail.Content = plugin.Log.Entries[i].Content.Data;
39                     }
40                     catch
41                     {
42                         detail.Content = null;
43                     }
44                     httpWatchDetail.Add(detail);
45                 }
46                 httpWatchSummary.Details = httpWatchDetail;
47             }
48             plugin.CloseBrowser();
49             return httpWatchSummary;
50         }
