`getdns` exceptions¶

getdns exceptions¶

exception getdns.error¶

getdns will throw an exception, getdns.error, under certain conditions. Those conditions include:

a required parameter having a bad value
a badly-formed domain name in the query
a bad Context() object
a failed Context() update
an out-of-bounds error for a getdns data structure
requesting an extension that doesn’t exist
requesting DNSSEC validation while using stub resolution

Please note that a successful return from a getdns method does not indicate that the query returned the records being requested, but rather that the query is formed correctly and has been submitted to the DNS. A getdns exception is typically the result of a coding error.

getdns will set the exception message to a diagnostic string, which may be examined for help in resolving the error.

Example¶

import getdns, sys

c = getdns.Context()
try:
    results = c.address('www.example.com', foo='bar')
except getdns.error, e:
    print(str(e))
    sys.exit(1)

This will result in “A required parameter had an invalid value” being printed to the screen.
