# 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](http://docs.python.org/library/logging.html) 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:
|
|
|
|
```python
|
|
import logging
|
|
from googleapiclient.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](https://github.com/httplib2/httplib2) module used by this library. The following code snippet enables logging of all HTTP request and response headers and bodies:
|
|
|
|
```python
|
|
import httplib2
|
|
httplib2.debuglevel = 4
|
|
``` |
