如何从烧瓶的日志记录中删除“- -”？

Question

当我运行 flask 0.9 时，我得到了日志记录：

127.0.0.1 - - [30/Mar/2016 10:08:38] "GET / HTTP/1.1" 200 -

我应该怎么做才能删除127.0.0.1和[30/Mar/2006 10:08:38]之间的- -？
如果我想从日志消息中删除响应代码 200 我应该怎么做？

如有任何建议，我们将不胜感激！

正如@alecxe 所建议的，我列出了我的代码片段相关日志记录：

logging.basicConfig(filename='werkzeug.log', level=logging.INFO)
logger = logging.getLogger('werkzeug')
logger.setLevel(logging.INFO)

您可以子类化 werkzeug.serving.WSGIRequestHandler 以覆盖您不喜欢的行为：

import logging
from flask import Flask
from werkzeug.serving import WSGIRequestHandler, _log

app = Flask(__name__)

@app.route('/hello')
def hello():
    return '<html><body><p>Hello, World.</p></body></html>'

class MyRequestHandler(WSGIRequestHandler):
    # Just like WSGIRequestHandler, but without "- -"
    def log(self, type, message, *args):
        _log(type, '%s [%s] %s\n' % (self.address_string(),
                                         self.log_date_time_string(),
                                         message % args))

    # Just like WSGIRequestHandler, but without "code"
    def log_request(self, code='-', size='-'):
        self.log('info', '"%s" %s', self.requestline, size)

if __name__=="__main__":
    logging.basicConfig(filename='werkzeug.log', level=logging.INFO)
    logger = logging.getLogger('werkzeug')
    logger.setLevel(logging.INFO)
    app.run(debug=True, request_handler=MyRequestHandler)

生成的日志文件：

INFO:werkzeug: * Running on http://127.0.0.1:5000/
INFO:werkzeug: * Restarting with reloader
INFO:werkzeug:127.0.0.1 [30/Mar/2016 02:28:24] "GET /?foo HTTP/1.1" -
INFO:werkzeug:127.0.0.1 [30/Mar/2016 02:28:28] "GET /hello HTTP/1.1" -
