Visual Studio 2013 WebTest请求失败:远程主机强制关闭现有连接

Question

我正在尝试在本地计算机上运行Visual Studio 2013 Web测试.这是我成功运行的测试(大约2个月前的最后一次).Web测试的第一步是对登录页面的GET请求.它看起来像这样:

获取https://example.com/Login.aspx

当我在网络浏览器中输入此网址时,它会成功.此外,我可以成功记录Web测试,我只是导航到此页面并登录.但是当我尝试重新运行我刚刚记录的webtest时,我得到了对GET请求的响应:

Request failed: An existing connection was forcibly closed by the remote host

在example.com上IIS没有记录任何内容(IIS不记录GET请求).但是,当我手动登录或者记录Web测试时,IIS会正确记录GET请求.

在example.com或我的本地主机上的事件查看器中没有记录消息.

任何有关如何调试此问题的建议都非常感谢.

Answer 1

对我来说,问题是TLS握手.通过添加插件进行Web测试解决.

思考是原始问题,这对我有所帮助:https://social.msdn.microsoft.com/Forums/vstudio/en-US/bc3ebf23-575d-4e54-bd6b-a1ed87fe5213/web-performance-test-is-not-working启用-with-tls12-？论坛= vstest
