我正在使用python urllib2连接HTTP服务器。有时我得到回复：httplib.BadStatusLine: ''。
我的代码：
response = None
try:
request = urllib2.Request(http_url,params)
response = urllib2.urlopen(request,timeout=5000)
return str(response.read())
except urllib2.HTTPError :
return ""
except urllib2.URLError:
return ""
响应错误：
File "/usr/lib64/python2.7/urllib2.py", line 154, in urlopen
return opener.open(url, data, timeout)
File "/usr/lib64/python2.7/urllib2.py", line 431, in open
response = self._open(req, data)
File "/usr/lib64/python2.7/urllib2.py", line 449, in _open
'_open', req)
File "/usr/lib64/python2.7/urllib2.py", line 409, in _call_chain
result = func(*args)
File "/usr/lib64/python2.7/urllib2.py", line 1244, in http_open
return self.do_open(httplib.HTTPConnection, req)
File "/usr/lib64/python2.7/urllib2.py", line 1217, in do_open
r = h.getresponse(buffering=True)
File "/usr/lib64/python2.7/httplib.py", line 1051, in getresponse
response.begin()
File "/usr/lib64/python2.7/httplib.py", line 415, in begin
version, status, reason = self._read_status()
File "/usr/lib64/python2.7/httplib.py", line 379, in _read_status
raise BadStatusLine(line)
httplib.BadStatusLine: ''
我不知道如何解决这个错误？我不知道为什么会收到错误回复。
