Python GeoIP2 AddressNotFoundError

Question

我试图使用Python GeoIP将IP地址转换为Geo详细信息，使用Maxmind数据库。

import urllib2
import csv
import geoip2.database
db = geoip2.database.Reader("GeoLite2-City.mmdb")
target_url="http://myip/all.txt"
data = urllib2.urlopen(target_url)
for line in data:
        response = db.city(line.strip())
        print line.strip(), response.country.name, response.country.iso_code, response.location.longitude, response.location.latitude

我得到错误"geoip2.errors.AddressNotFoundError:地址103.229.234.197不在数据库中。“

    Traceback (most recent call last):
  File "script.py", line 14, in <module>
    response = db.city(line.strip())
  File "/usr/lib/python2.7/site-packages/geoip2/database.py", line 110, in city
    return self._model_for(geoip2.models.City, 'City', ip_address)
  File "/usr/lib/python2.7/site-packages/geoip2/database.py", line 180, in _model_for
    record = self._get(types, ip_address)
  File "/usr/lib/python2.7/site-packages/geoip2/database.py", line 176, in _get
    "The address %s is not in the database." % ip_address)
geoip2.errors.AddressNotFoundError: The address 103.229.234.197 is not in the database.

Maxmind db提到的地址不是在数据库中。然而，这并不会伤害我，但是一个人怎么能忽略这个错误并得到我的输出，而这些输出是可用的？

尝试排除任何错误(虽然不是最好的方法)，并期待特定的AddressNotFoundError。

try:
     print line.strip(), response.country.name, response.country.iso_code, response.location.longitude, response.location.latitude
except:
       pass

还有，

try:
     print line.strip(), response.country.name, response.country.iso_code, response.location.longitude, response.location.latitude

except AddressNotFoundError:
     pass

还是没有运气。

任何建议。

这里的问题是在db.city调用中发生的异常，而不是在值打印中发生的异常，因此您可以尝试这样做：

import urllib2
import csv
import geoip2.database
db = geoip2.database.Reader("GeoLite2-City.mmdb")
target_url="http://myip/all.txt"
data = urllib2.urlopen(target_url)
for line in data:
    try:
        response = db.city(line.strip())
        print line.strip(), response.country.name, response.country.iso_code, response.location.longitude,   response.location.latitude
    exception:
        pass
