Can someone help me on how I can catch this error?
import pygeoip
gi = pygeoip.GeoIP('GeoIP.dat')
print gi.country_code_by_name('specificdownload.com')
Traceback (most recent call last):
File "<module1>", line 14, in <module>
File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 447, in country_code_by_name
addr = self._gethostbyname(hostname)
File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 392, in _gethostbyname
return socket.gethostbyname(hostname)
gaierror: [Errno 11001] getaddrinfo failed
推荐答案
好,让我们问一下Python是什么类型的异常:
Well, let’s ask Python what type of exception that is:
#!/usr/bin/env python2.7
import pygeoip
gi = pygeoip.GeoIP('GeoIP.dat')
try:
print gi.country_code_by_name('specificdownload.com')
except Exception, e:
print type(e)
print e
打印:
$ ./foo.py
<class 'socket.gaierror'>
[Errno 8] nodename nor servname provided, or not known
所以我们需要赶上socket.gaierror
,就像这样:
So we need to catch socket.gaierror
, like so:
#!/usr/bin/env python2.7
import pygeoip
import socket
gi = pygeoip.GeoIP('GeoIP.dat')
try:
print gi.country_code_by_name('specificdownload.com')
except socket.gaierror:
print 'ignoring failed address lookup'
尽管仍然存在问题,gaierror
到底是什么? Google出现了 socket.gaierror
文档,其中说,
Though there’s still the question of, what the heck is gaierror
? Google turns up the socket.gaierror
documentation, which says,
对于与地址相关的错误(对于
getaddrinfo()
和getnameinfo()
所以GAI错误=获取地址信息错误.
So GAI Error = Get Address Info Error.
