Integrating Logging with Frameworks
Integrating Logging with the FastAPI Framework
The FastAPI web framework provides built-in support for logging, which can be easily integrated with the Python logging
module. Here's an example of how to configure logging in a FastAPI application:
## main.py
import logging
from fastapi import FastAPI
app = FastAPI()
## Configure the logging system
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s %(levelname)s: %(message)s',
datefmt='%Y-%m-%d %H:%M:%S'
)
@app.get("/")
def read_root():
logging.info("This is an informational message")
logging.error("This is an error message")
return {"Hello": "LabEx"}
In this example, we configure the logging system to log messages at the INFO level, and then use the logging
module to log messages within the FastAPI application.
Integrating Logging with the Pyramid Framework
The Pyramid web framework also provides built-in support for logging, which can be integrated with the Python logging
module. Here's an example of how to configure logging in a Pyramid application:
## app.py
import logging
from pyramid.config import Configurator
from pyramid.response import Response
def hello_world(request):
logging.info("This is an informational message")
logging.error("This is an error message")
return Response("Hello, LabEx!")
if __name__ == '__main__':
with Configurator() as config:
config.add_route('hello', '/')
config.add_view(hello_world, route_name='hello')
## Configure the logging system
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s %(levelname)s: %(message)s',
datefmt='%Y-%m-%d %H:%M:%S'
)
app = config.make_wsgi_app()
from wsgiref.simple_server import make_server
server = make_server('0.0.0.0', 8000, app)
server.serve_forever()
In this example, we configure the logging system to log messages at the INFO level, and then use the logging
module to log messages within the Pyramid application.
Integrating Logging with the Tornado Framework
The Tornado web framework also provides built-in support for logging, which can be integrated with the Python logging
module. Here's an example of how to configure logging in a Tornado application:
## app.py
import logging
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
logging.info("This is an informational message")
logging.error("This is an error message")
self.write("Hello, LabEx!")
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
## Configure the logging system
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s %(levelname)s: %(message)s',
datefmt='%Y-%m-%d %H:%M:%S'
)
app = make_app()
app.listen(8000)
tornado.ioloop.IOLoop.current().start()
In this example, we configure the logging system to log messages at the INFO level, and then use the logging
module to log messages within the Tornado application.
