python3记录器-UnicodeEncodeError

时间：2018-10-19 16:28:57

标签： python python-3.x

我有一个这样的记录器设置：

import logging
from logging.handlers import RotatingFileHandler
import sys

# root logger
logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)

# create a file logger
handler = RotatingFileHandler('log/core-application.log', maxBytes=1024*1024*1, backupCount=3)
handler.setLevel(logging.INFO)
formatter = logging.Formatter('%(asctime)s - %(funcName)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)


# create stdout logger
handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(funcName)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)

logger.info('Logging all setup')

在我的开发系统上，此日志记录条目运行正常。它记录您在这里看到的内容：

logger.info('message key: {}'.format('2018-10-19_00:20:56_\xd8\xa7\xd9\x84\xd8\xb5\xd9\x88\xd8\xa7\xd9\x81/'))

我的ubuntu AWS EC2服务器上的同一行显示了一个错误：

  

---记录错误---追溯（最近一次调用最后一次）：文件“ /usr/lib/python3.5/logging/init.py”，发射行982       stream.write（msg）UnicodeEncodeError：'ascii'编解码器无法对位置108-113中的字符进行编码：序数不在范围（128）中

有人能想象为什么吗？

顺便说一句： EC2服务器的语言环境为：

LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8

谢谢。

对我有用的是在处理程序中添加encoding ='utf8'arg：

 formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')
 log_path = '/var/log/app'
 log_file = '%s/%s.log' % (log_path, name)
 create_log_file(log_file)
 handler = logging.FileHandler(log_file, encoding='utf8')
 handler.setFormatter(formatter)
 logger.addHandler(handler)

我刚刚找到了解决方案，并希望分享答案：

它已连接到管理服务器上python应用程序的主管。 Supervisor配置需要以某种方式包含下面的环境变量，以便能够将UTF-8打印到stdout。

Finished executing TestScript. Please check for errors.

This is the TestScript groovy script

class TestScript {
    static void main(String[] args) {
        println "Hello World"
    }

}

Python 3.7似乎旨在自动解决此问题。

答案 2 :(得分：1)

搜索了很长一段时间后，此解决方案在Windows 10 x64和Python 3.7.6下为我工作，每当`logger.error（'message'，exc_info = True）因为回溯包含无效字符而失败时，该解决方案便对我有效。

在格式化程序字符串之前添加一个u以强制unicode消息：

#formatter = logging.Formatter('%(asctime)s - %(funcName)s - %(levelname)s - %(message)s'
formatter = logging.Formatter(u'%(asctime)s - %(funcName)s - %(levelname)s - %(message)s'

希望对任何阅读本书的人都有帮助。
