What errors/exceptions do I need to handle with urllib2.Request / urlopen?

Question

I have the following code to do a postback to a remote URL:

request = urllib2.Request(\'http://www.example.com\', postBackData, { \'User-Agent\' : \'My User          


        

Answer 1

You can catch all exceptions and log what's get caught:

 import sys
 import traceback
 def formatExceptionInfo(maxTBlevel=5):
     cla, exc, trbk = sys.exc_info()
     excName = cla.__name__
     try:
         excArgs = exc.__dict__["args"]
     except KeyError:
         excArgs = ""
     excTb = traceback.format_tb(trbk, maxTBlevel)
     return (excName, excArgs, excTb)
 try:
     x = x + 1
 except:
     print formatExceptionInfo()

(Code from http://www.linuxjournal.com/article/5821)

Also read documentation on sys.exc_info.
