tornado：ValueError：需要多于1个值才能解压缩

Question

我在龙卷风中遇到这个错误：

Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/tornado/curl_httpclient.py", line 480, in _curl_header_callback
    headers.parse_line(header_line)
  File "/Library/Python/2.7/site-packages/tornado/httputil.py", line 189, in parse_line
    name, value = line.split(":", 1)
ValueError: need more than 1 value to unpack

我有一个100个代理服务器列表，我正用它来拨打电话。使用其中一些代理进行呼叫时会发生这种情况。

request = tornado.httpclient.HTTPRequest(url)
request.proxy_host = proxy['host']
request.proxy_port = proxy['port']
HTTP_CLIENT.fetch(request, handle_response)

非常感谢任何帮助。
