Exception urllib异常http.client.BadStatusLine

我一辈子都弄不明白为什么我不能抓住这个例外

看看这里

例外情况：

Traceback (most recent call last):
  File "queue_cleaner_main.py", line 60, in <module>
    sys.exit(main())
  File "queue_cleaner_main.py", line 57, in main
    team_names_to_contact = queue_cleaner_functions.get_team_names(SERVICE_NOW_TEAM_NAME_URL, team[2])
  File "D:\oppssup\old_job\queue_cleaner_functions.py", line 132, in get_team_names
    response = urllib.request.urlopen(get_team_id_url + team_id)
  File "C:\Python34\lib\urllib\request.py", line 153, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python34\lib\urllib\request.py", line 455, in open
    response = self._open(req, data)
  File "C:\Python34\lib\urllib\request.py", line 473, in _open
    '_open', req)
  File "C:\Python34\lib\urllib\request.py", line 433, in _call_chain
    result = func(*args)
  File "C:\Python34\lib\urllib\request.py", line 1202, in http_open
    return self.do_open(http.client.HTTPConnection, req)
  File "C:\Python34\lib\urllib\request.py", line 1177, in do_open
    r = h.getresponse()
  File "C:\Python34\lib\http\client.py", line 1172, in getresponse
    response.begin()
  File "C:\Python34\lib\http\client.py", line 351, in begin
    version, status, reason = self._read_status()
  File "C:\Python34\lib\http\client.py", line 321, in _read_status
    raise BadStatusLine(line)
http.client.BadStatusLine: ''

例外情况：

Traceback (most recent call last):
  File "queue_cleaner_main.py", line 60, in <module>
    sys.exit(main())
  File "queue_cleaner_main.py", line 57, in main
    team_names_to_contact = queue_cleaner_functions.get_team_names(SERVICE_NOW_TEAM_NAME_URL, team[2])
  File "D:\oppssup\old_job\queue_cleaner_functions.py", line 141, in get_team_names
    r_json = json.loads(response.read().decode('utf8'))
UnboundLocalError: local variable 'response' referenced before assignment

回溯（最近一次呼叫最后一次）：
文件“queue_cleaner_main.py”，第60行，在
sys.exit（main（））
文件“queue_cleaner_main.py”，第57行，在main中
团队名称\u to\u contact=队列\u cleaner\u函数。获取团队名称（服务\u NOW\u团队名称\u URL，团队[2]）
文件“D:\oppsup\old\u job\queue\u cleaner\u functions.py”，第141行，位于get\u团队名称中
r_json=json.load（response.read（）.decode（'utf8'））
UnboundLocalError:赋值前引用的局部变量“response”

此

http.client.BadStatusLine

是

http.client.HTTPException

的子类。我认为如果你这样做：

try:
    response = urllib.request.urlopen(get_team_id_url + team_id)
except http.client.HTTPException as e:
    print(e)

---

那么你应该没问题抓住它。然而，造成这种情况的原因可能是您应该关心的。

您好，skyline，谢谢您的回复。当我添加这一行时，我得到下面的错误文件“D:\oppsup\old\u job\queue\u cleaner\u functions.py”，第112行，在get\u team\u name中，http.client.HTTPException为e:name错误：名称“http”未定义您导入的ID

http

？感谢mate修复了它。为什么我需要导入http，而我甚至不使用它，只是为了捕获一个异常？我认为异常处理只由使用的每个导入模块处理，而不必导入特定模块来处理另一个模块中的异常？我认为这可能是python3中

urllib

的某种设计缺陷。我也不喜欢导入其他LIB的需要。三年多后，它帮助了我。谢谢你，伙计！这里是py3.6。
