添加客户端IP地址到烧瓶记录

Question

import logging
from flask import request, has_request_context


class RequestFormatter(logging.Formatter):
    def format(self, record):
        if has_request_context():
            record.remote_addr = request.remote_addr
        else:
            record.remote_addr = 'unknown'
        return super().format(record)

stream_handler = logging.StreamHandler()

formatter = RequestFormatter('{"logger": "%(name)s", "level": "%(levelname)s", "timestamp": "%(asctime)s", "message": "%(message)s", "ip": "%(remote_addr)s", "filename": "%(filename)s", "function": "%(funcName)s", "line": %(lineno)d}')
stream_handler.setFormatter(formatter)


logging.basicConfig(level=logging.NOTSET, handlers=[stream_handler])


loggers = [logging.getLogger(name) for name in logging.root.manager.loggerDict]
for logger in loggers:
    logger.handlers = []
    logger.addHandler(stream_handler)
    logger.propagate = False


logging.getLogger().handlers = []
logging.getLogger().addHandler(stream_handler)

现在，请求Formatter将Record.Remote_Addr设置为Unknown，因为HAS_REQUEST_CONTEXT（）始终返回false。我尝试将请求构造类移至app.py文件中，但这无济于事。我在做什么错？

你几乎是正确的。我认为，请求上下文在

werkzeug

中不可用，这就是为什么IP为

。您还应该更改Flask默认处理程序的格式化器。您也可以使用

.clear()

删除所有处理程序。我还建议使用烧瓶应用的记录器（例如

app.logger.info(...)

.

我是我编辑的代码：

import logging

from flask.logging import default_handler
from flask import Flask, request, has_request_context


LOGGING_FORMAT: str = '{"logger": "%(name)s", "level": "%(levelname)s", "timestamp": "%(asctime)s", "message": "%(message)s", "ip": "%(remote_addr)s", "filename": "%(filename)s", "function": "%(funcName)s", "line": %(lineno)d}'


class RequestFormatter(logging.Formatter):
    def format(self, record):
        if has_request_context():
            record.remote_addr = request.remote_addr
        else:
            record.remote_addr = "unknown"
        return super().format(record)


def setup_logging() -> None:
    stream_handler = logging.StreamHandler()
    logging.basicConfig(level=logging.NOTSET, handlers=[stream_handler])

    formatter = RequestFormatter(LOGGING_FORMAT)

    stream_handler.setFormatter(formatter)
    default_handler.setFormatter(formatter)

    for logger_name in logging.root.manager.loggerDict:
        logger = logging.getLogger(logger_name)
        logger.handlers.clear()
        logger.addHandler(stream_handler)
        logger.propagate = False


def make_app() -> Flask:
    app = Flask(__name__)

    @app.route("/")
    def root():
        app.logger.info("Logging works!")

        return "hello"

    return app


if __name__ == "__main__":
    setup_logging()
    make_app().run(debug=True, port=2121)

，我没有完全理解您的方法。如果需要JSON格式记录，则可以将其登录到某些文件而不是

stdout中，您可以轻松地通过记录/监视解决方案集成。但是看上去很糟糕。
