有没有可能让logging.handlers.httpHandler在不使用定制代码的情况下将内容头设置为JSON？

import logging
import logging.handlers
import json

class JSONHTTPHandler(logging.handlers.HTTPHandler):
    def emit(self, record):
        try:
            log_entry = self.format(record)
            log_entry_json = json.dumps(log_entry)
            
            request = self.makePickle(log_entry_json)
            self.send(self.host, self.url, request)
            
        except (KeyboardInterrupt, SystemExit):
            raise
        except:
            self.handleError(record)

# 使用示例
logger = logging.getLogger()
handler = JSONHTTPHandler('localhost:8000', '/log')
logger.addHandler(handler)

logger.warning('This is a warning message.')
