The @app.errorhandler decorated method is called in the context of an
exception, so you can use app.logger.exception to log a message and the
original exception with traceback:
import loggingimport sys
import flaskimport werkzeug.exceptions
handler = logging.StreamHandler(stream=sys.stderr)
app = flask.Flask(__name__)
app.logger.addHandler(handler)
@app.route('/')def get():
raise Exception('oh noes')
return 'hello'
@app.errorhandler(Exception)def handle_error(exc):
app.logger.exception('Unhandled Exception')
return werkzeug.exceptions.InternalServerError()
app.run()
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
Unhandled Exception
