Question

我的Python脚本创建了一个WebSocket，并且能够使用该WebSocket连接到服务器。服务器在我创建的WebSocket上发送响应，但WebSocket模块似乎无法对其进行解码。

这是我看到的错误：

-----------------------
Traceback (most recent call last):
  File "test_file.py", line 307, in <module>
    result = ws.recv()
  File "/usr/local/lib/python2.7/dist-packages/websocket/_core.py", line 293, in recv
    opcode, data = self.recv_data()
  File "/usr/local/lib/python2.7/dist-packages/websocket/_core.py", line 310, in recv_data
    opcode, frame = self.recv_data_frame(control_frame)
  File "/usr/local/lib/python2.7/dist-packages/websocket/_core.py", line 334, in recv_data_frame
    return self.cont_frame.extract(frame)
  File "/usr/local/lib/python2.7/dist-packages/websocket/_abnf.py", line 428, in extract
    "cannot decode: " + repr(frame.data))
websocket._exceptions.WebSocketPayloadException: cannot decode: '\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x03\x9dUmk\xeb6\x14\xfe+\xc1\x1f\xc7ug\'v\x1c\x17\xc6\xb8t\xa5\x0b\xac\xbdwm\x06\x83\xb9\x08Y>N\xb5kK\x8e$\'\xcdJ\xff\xfbt$;vac0\x87\x18\xe9\xbc<\xe7\xfd\xf8m\x11\x80RR1YAp\xbd\x88>-\x82\x16\xb4\xa6{\xbc\x05\x9f\xf7 \xccW%_\xcf7\xb2m{\xc1\x195\\\x8a\xc0JqMz\'

这是我在启动websocket并收听服务器resopnse的代码：

ws = websocket.create_connection(full_url, header = header_set)
result = ws.recv()
print result

它在ws.recv()行失败了。有什么想法吗？

这似乎是let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.alignment = .center let bigAttr = [NSForegroundColorAttributeName: UIColor.white, NSFontAttributeName: UIFont.systemFont(ofSize: 60, weight: UIFontWeightLight), NSParagraphStyleAttributeName: paragraphStyle] let smallAttr = [NSFontAttributeName: UIFont.systemFont(ofSize: 12, weight: UIFontWeightLight)] let attributedString = NSMutableAttributedString(string: "\(speedInt)", attributes: bigAttr) attributedString.append(NSAttributedString(string: "\nkm/h", attributes: smallAttr)) statusLabel.attributedText = attributedString版本websocket-client的已知问题。尝试将软件包更新到0.16或更高版本，看看是否能解决问题。

显然，这是因为0.34改变了他们在websocket-client之后的版本中处理帧验证的方式（不完全确定版本是什么，所以请尝试更新到最新版本。）
