如何使用urllib接收数据来解决此崩溃问题？

Question

我尝试使用urllib从http://ustc.edu.cn获取数据。但是，当我尝试从recv调用中分配返回时，程序会因此追溯而崩溃：

>>> urllib.urlopen('http://ustc.edu.cn')
^CTraceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/usr/lib/python2.7/urllib.py", line 87, in urlopen
        return opener.open(url)
    File "/usr/lib/python2.7/urllib.py", line 213, in open
        return getattr(self, name)(url)
    File "/usr/lib/python2.7/urllib.py", line 351, in open_http
        errcode, errmsg, headers = h.getreply()
    File "/usr/lib/python2.7/httplib.py", line 1202, in getreply
        response = self._conn.getresponse()
    File "/usr/lib/python2.7/httplib.py", line 1127, in getresponse
        response.begin()
    File "/usr/lib/python2.7/httplib.py", line 453, in begin
        version, status, reason = self._read_status()
    File "/usr/lib/python2.7/httplib.py", line 409, in _read_status
        line = self.fp.readline(_MAXLINE + 1)
    File "/usr/lib/python2.7/socket.py", line 480, in readline
        data = self._sock.recv(self._rbufsize)
KeyboardInterrupt

有时，它也会返回＆＃34;连接重置由同行＆＃34;消息。
