Question

bluemix上是否有任何websocket客户端的工作示例？

我尝试了许多在Github中找到的例子，但它没有用。服务器是使用node red创建的，HTML实例可以与node red server进行通信。但是，python无法进行通信。这是我的代码：

ws = create_connection("host name")
print "Sending 'Hello, World'..."
ws.send("Hello, World")
print "Sent"
print "Receiving..."
result =  ws.recv()
print "Received '%s'" % result

在上面的示例中，创建连接期间握手失败。我在互联网上尝试了很多其他的例子，但没有一个能够正常运作。

编辑：添加有关握手问题的更多详细信息：
