TFS 工作流活动在构建、自定义或固定后调用 REST 服务？

Question

我有一个 NuGet 存储库，每次构建后都会获取一个包。我有一项 REST 服务，它是 NuGet 服务器的扩展，它将删除低于指定包的所有包。将房间连接在一起的地毯将是一个可以在构建和部署后调用此 REST 服务的操作。我的问题是，REST 活动是否已经存在，或者我是否需要构建它？

好吧，我创建了自己的 REST 客户端活动。我确信它有一些错误，但它对我有用。

using System;
using System.Activities;
using System.Net;
using Microsoft.TeamFoundation.Build.Client;

namespace Custom.BuildActivities
{
    [BuildExtension(HostEnvironmentOption.Agent)]
    [BuildActivity(HostEnvironmentOption.All)]
    public sealed class RESTClient : CodeActivity
    {
        public InArgument<Uri> Url { get; set; }
        public InArgument<string> Verb { get; set; }

        public OutArgument<HttpStatusCode> StatusCode { get; set; }
        public OutArgument<string> ErrorMessage { get; set; }

        protected override void Execute(CodeActivityContext context)
        {
            try
            {
                Uri url = context.GetValue(this.Url);
                string verb = context.GetValue(this.Verb);

                HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
                request.Method = verb;

                HttpWebResponse response = null;
                try
                {
                    response = request.GetResponse() as HttpWebResponse;
                    context.SetValue(this.StatusCode, response.StatusCode);
                }
                catch (WebException webEx)
                {
                    if (webEx.Response != null)
                    {
                        context.SetValue(this.StatusCode, ((HttpWebResponse)webEx.Response).StatusCode);
                    }
                    else
                    {
                        context.SetValue(this.StatusCode, HttpStatusCode.BadRequest);
                    }
                }
            }
            catch (Exception ex)
            {
                context.SetValue(this.ErrorMessage, ex.ToString());
            }
        }
    }
}
