In a python project with multiple threads my logging works well to write to a logger file. Basically based on Logging, StreamHandler and standard streams
Part of my project is a bottle web server which runs well also. But every bottle call writes a log to the console like this:
192.168.178.20 - - [26/Jun/2015 20:22:17] "GET /edit?addJob HTTP/1.1" 200 48028
How to handle this the same way as with the other code, so the bottle logs go also to the logger file?
If you're rolling your own solution, you should write a simple Bottle plugin that emits log lines to a logging logger. Here's an example that sets up a basic logger, defines the logging plugin, and creates a Bottle app with that plugin installed on all routes.
from bottle import Bottle, request, response
from datetime import datetime
from functools import wraps
import logging
logger = logging.getLogger('myapp')
# set up the logger
logger.setLevel(logging.INFO)
file_handler = logging.FileHandler('myapp.log')
formatter = logging.Formatter('%(msg)s')
file_handler.setLevel(logging.DEBUG)
file_handler.setFormatter(formatter)
logger.addHandler(file_handler)
def log_to_logger(fn):
'''
Wrap a Bottle request so that a log line is emitted after it's handled.
(This decorator can be extended to take the desired logger as a param.)
'''
@wraps(fn)
def _log_to_logger(*args, **kwargs):
request_time = datetime.now()
actual_response = fn(*args, **kwargs)
# modify this to log exactly what you need:
logger.info('%s %s %s %s %s' % (request.remote_addr,
request_time,
request.method,
request.url,
response.status))
return actual_response
return _log_to_logger
app = Bottle()
app.install(log_to_logger)
@app.route('/')
def home():
return ['hello, world']
app.run(host='0.0.0.0', port='8080', quiet=True)
Running that code yields what you want:
% python myapp.py &
% curl -v http://localhost:8080/
% tail myapp.log
127.0.0.1 2015-06-27 16:57:09.983249 GET http://localhost:8080/ 200 OK
