Python脚本奇怪的问题

嘿，我正在使用python脚本测试web商务网站上的功能。我将此脚本放在Pythonywhere站点上，有时连续工作7天没有问题，但有时会出现如下错误：

Logged in with test_cart
    Open http://[***]/electronics/page/1
Search ... iphone
[****************]
    File "/home/.../cart-pickup.py", line 58, in alo
    site = opener.open(url)
    File "/usr/local/lib/python2.7/urllib2.py", line 400, in open
    response = self._open(req, data)
    File "/usr/local/lib/python2.7/urllib2.py", line 418, in _open
    '_open', req)
    File "/usr/local/lib/python2.7/urllib2.py", line 378, in _call_chain
    result = func(*args)
    File "/usr/local/lib/python2.7/urllib2.py", line 1207, in http_open
    return self.do_open(httplib.HTTPConnection, req)
    File "/usr/local/lib/python2.7/urllib2.py", line 1180, in do_open
    r = h.getresponse(buffering=True)
    File "/usr/local/lib/python2.7/httplib.py", line 1030, in getresponse
    response.begin()
    File "/usr/local/lib/python2.7/httplib.py", line 407, in begin
    version, status, reason = self._read_status()
    File "/usr/local/lib/python2.7/httplib.py", line 371, in _read_status
    raise BadStatusLine(line)
    httplib.BadStatusLine: ''
    >>>         

你知道可能是什么吗？

提前感谢

您可以通过使用

try.教您的程序如何在不崩溃的情况下恢复。

除外：

try:
    site = opener.open(url)  # line 58 in cart-pickup.py
except IOError: 
    print "Error: Site not loading or it isnt UP. Retrying..." 
    # return site # This will cause a NameError if site is not defined.
    return url    # Perhaps you meant this?
except httplib.BadStatusLine:
    # log opening `url` did not succeed, or
    # queue it to be tried again, etc.
    pass

我认为这不是Python脚本的问题，而是它试图与之对话的web服务器的问题。我是Python新手。所以我不知道是否有可能在一段时间内有两个例外。我的代码如下所示：def alo（url）：testurl=1，而testurl==1:try:site=opener.open（url）lagsafe=0，除了IOError:print“错误：站点未加载或未启动。重试…”返回站点，那么我如何才能找到你的代码？只需在当前的except之后添加第二个except。不起作用。它说错误的语法，并把它闲置闪烁（我使用windows）在第二，除了：）我检查了我的代码；我没有看到任何错误。请发布您的代码。可能我在这里做错了：#日志打开

url

没有成功，或者#排队等待重试，等等。您能给我一些例子吗？谢谢
