所以我尝试r = br.open('https://beststresser.com')，但这是我得到的输出：
Traceback (most recent call last):
File "DDoS.py", line 15, in <module>
r = br.open('https://beststresser.com')
File "/usr/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 203, in open
return self._mech_open(url, data, timeout=timeout)
File "/usr/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 255, in _mech_open
raise response
mechanize._response.httperror_seek_wrapper: HTTP Error 503: Service Temporarily Unavailable
当我尝试其他网址，例如r = br.open('https://google.com')时，它可以正常工作。但https://beststresser.com是有效的网址...
