在TFS中通过程序动态创建Bug并感知Bug解决状态

  为便于跟踪问题解决情况，预警引擎产生的比较严重的预警日志，需要在TFS中登记Bug，通过TFS的状态流转，利用TFS Bug的Web挂钩功能，动态感知Bug解决状态，从而跟踪预警问题的解决状态，

  整体解决方案如下：

微软提供了很好的文档支持：

https://www.visualstudio.com/en-us/docs/integrate/api/wit/work-items#create-bug

创建Bug示例代码如下：

public void CreateBug()
{
   string _userName = "userName";
   string _userPwd = "userPwd";
   string _credentials = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", _userName , _userPwd)));

   Object[] patchDocument = new Object[4];

   patchDocument[0] = new { op = "add", path = "/fields/System.Title", value = "Authorization Errors" };
   patchDocument[1] = new { op = "add", path = "/fields/Microsoft.VSTS.TCM.ReproSteps", value = "ReproSteps" };
   patchDocument[2] = new { op = "add", path = "/fields/Microsoft.VSTS.Common.Priority", value = "1" };
   patchDocument[3] = new { op = "add", path = "/fields/Microsoft.VSTS.Common.Severity", value = "2 - High" };

   //use the httpclient
   using (var client = new HttpClient())
   {
       //set our headers
       client.DefaultRequestHeaders.Accept.Clear();
       client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
       client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", _credentials);

       //serialize the fields array into a json string
       var patchValue = new StringContent(JsonConvert.SerializeObject(patchDocument), Encoding.UTF8, "application/json-patch+json"); 

       var method = new HttpMethod("PATCH");
       var request = new HttpRequestMessage(method, "TFS Bug URL") { Content = patchValue };
       var response = client.SendAsync(request).Result;

       //if the response is successfull, set the result to the workitem object
       if (response.IsSuccessStatusCode)
       {
           var result = response.Content.ReadAsStringAsync().Result;
       }
   }
}

返回的result是一个Json串，形如：

    "rev": 1,
    "fields": {
        "System.AreaPath": "Bugs",

    },

}

 以前只用过Http协议中的Get、Post、Put等，这个Patch方法，还是第一次用。
