log is not writing into file

Question

I want to write log into file. File is creating but nothing is writing into file. my code is:

app = Flask(__name__)
formatter = logging.Formatter("[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s")

handler = RotatingFileHandler('/var/log/httpd/myfile.log', maxBytes=100000, backupCount=10)
handler.setLevel(logging.INFO)
handler.setFormatter(formatter)
logger = logging.getLogger("__init__")
logger.setLevel(logging.INFO)
logger.addHandler(handler)

@app.route('/api/urlname', methods=['GET'])
def api_url():
    logger.info("----- REST API is called -----")
    ....
    .....


if __name__ == '__main__':
   app.run()

When calling /api/urlname code is executing and getting result but not see any log in file. I gave full permission to myfile.log like: sudo chmod -R 777 myfile.log.

Can you tell where I did wrong and why log is not writing into file?

Answer 1

您应该将setLevel(logging.info)都更改为setLevel(logging.INFO)因为logging.info是一个函数，而logging.INFO是一个整数（在本例中为20），代表信息日志记录的日志记录级别。
