c# - 为什么在尝试连接到 localhost 时会出现错误？

Question

我正在开发一个需要连接到运行 express.js 的 node.js 服务器的项目，该服务器正在我的计算机上运行。我运行以下代码：

HttpWebRequest myRequest;
WebResponse myResponse;
StreamReader sr;
myRequest = (HttpWebRequest)WebRequest.Create("https://localhost:1337/Test.txt");
myRequest.Method = "GET";
myResponse = myRequest.GetResponse();
sr = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
sr.Close();
myResponse.Close();

并得到以下错误：

System.Windows.Markup.XamlParseException
  HResult=0x80131501
  Message=The invocation of the constructor on type 'MyNamespace.MyClass' that matches the specified binding constraints threw an exception.

Inner Exception 2:
HttpRequestException: The SSL connection could not be established, see inner exception.

Inner Exception 3:
IOException: The handshake failed due to an unexpected packet format.

该代码旨在连接到服务器，读取在其上运行的测试文件并返回文件的内容。

我也试过关闭windows防火墙，但它什么也没做。
