Logging
This page provides logging tips to help you debug your applications.
Log Level
You can enable logging of key events in this library by configuring Python's standard logging module. You can set the logging level to one of the following:
- CRITICAL (least amount of logging)
- ERROR
- WARNING
- INFO
- DEBUG (most amount of logging)
In the following code, the logging level is set to INFO
, and the Google Translate API is called:
import logging from apiclient.discovery import build logger = logging.getLogger() logger.setLevel(logging.INFO) def main(): service = build('translate', 'v2', developerKey='your_api_key') print service.translations().list( source='en', target='fr', q=['flower', 'car'] ).execute() if __name__ == '__main__': main()
The output of this code should print basic logging info:
INFO:root:URL being requested: https://www.googleapis.com/discovery/v1/apis/translate/v2/rest INFO:root:URL being requested: https://www.googleapis.com/language/translate/v2?q=flower&q=car&source=en&alt=json&target=fr&key=your_api_key {u'translations': [{u'translatedText': u'fleur'}, {u'translatedText': u'voiture'}]}
HTTP Traffic
For even more detailed logging you can set the debug level of the httplib2 module used by this library. The following code snippet enables logging of all HTTP
request and response headers and bodies:
import httplib2 httplib2.debuglevel = 4
