Question

大家好，我有一个json程序，它将以json格式提供日志文件，但是我无法获取输出...这是一个名为“ logging.json”的json文件

{
    "version": 1,
    "disable_existing_loggers": false,
    "formatters": {
        "json": {
        "format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s",
            "()": "pythonjsonlogger.jsonlogger.JsonFormatter"
        }
    },
    "handlers": {
        "console": {
            "class": "logging.StreamHandler",
            "formatter": "json"
        }
    },

    "file_handler": {
            "class": "logging.handlers.RotatingFileHandler",
            "level": "INFO",
            "formatter": "json",
            "filename": "Data-Generation.log",
            "mode": "a",
            "encoding": "utf8"
        },

    "root": {
       "level": "DEBUG",
       "handlers": ["console", "file_handler"]
    }
}

现在我正在尝试像这样在python程序中访问：

fp = open('logging.json')
logging.config.dictConfig(json.load(fp))
logger = logging.getLogger(__name__)
fp.close()
logger.info("Logging is started")

我遇到此错误：

Traceback (most recent call last):
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 753, in add_handlers
    logger.addHandler(self.config['handlers'][h])
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 315, in __getitem__
    value = dict.__getitem__(self, key)
KeyError: 'file_handler'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 634, in configure
    self.configure_root(root)
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 786, in configure_root
    self.common_logger_config(root, config, incremental)
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 770, in common_logger_config
    self.add_handlers(logger, handlers)
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 755, in add_handlers
    raise ValueError('Unable to add handler %r' % h) from e
ValueError: Unable to add handler 'file_handler'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "F:\Codedata\scratch\Python\ManufactureDataWithDateRange\ActionHandler.py", line 17, in <module>
    logging.config.dictConfig(json.load(fp))
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 792, in dictConfig
    dictConfigClass(config).configure()
  File "C:\Users\rahul\AppData\Local\Programs\Python\Python37-32\lib\logging\config.py", line 637, in configure
    'logger') from e
ValueError: Unable to configure root logger

注意：，当我尝试在以json格式打印日志之前尝试在json文件中添加“ streamHandler”时，就会发生这种情况。我认为“ config”中存在问题.dictConfig” ，我不知道...请帮助我。 没有“ StreamHandler”的工作程序是：

{
    "version": 1,
    "disable_existing_loggers": false,
    "formatters": {
        "json": {
        "format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s",
            "()": "pythonjsonlogger.jsonlogger.JsonFormatter"
        }
    }, 
"handlers": {
       "file_handler": {
           "class": "logging.handlers.RotatingFileHandler",
           "level": "DEBUG",
           "formatter": "json",
           "filename": "Data-Generation.log",
           "encoding": "utf8"
       }
   },

   "root": {
       "level": "DEBUG",
       "handlers": ["file_handler"]
       }
     }

这是正确的Json格式并打印日志，但想从我的日志中删除所有不需要的行，因此我尝试包括“ streamHnadler”，请帮助我该怎么做...谢谢 < / p>
