flask应用程序启动时没有给出调试引脚,也没有显示请求信息

Question

我真的不确定我是如何进入这种模式的,但是当我在开发系统上启动我的烧瓶应用程序时,我明白了

2016-11-17 17:20:36,717 WARNING: * Debugger is active!

但没有显示调试PIN,我没有看到进入服务器的请求.

当这种情况开始发生时,我喋喋不休地试着看看我做了什么改变导致了这一点,但过于卷入使应用程序在当时跟进工作.当然,任何历史早已不复存在.

你对如何调试这个有什么建议吗？

如果它很重要,我正在Windows上运行.

我使用转储了app.config

        configkeys = app.config.keys()
        configkeys.sort()
        appconfig = []
        for key in configkeys:
            value = app.config[key]
            if not owner_permission.can():
                if key in ['SQLALCHEMY_DATABASE_URI','SECRET_KEY']:
                    value = '<obscured>'
            appconfig.append({'label':key, 'value':value})
        sysvars.append(['app.config',appconfig])

(稍后在html模板中显示sysvars)并查看以下内容.我也试着设置debug=True在run()调用,但没有效果.

问题结果是,当werkzeug启动时,日志级别设置不正确,导致信息消息被遮挡.需要进一步调试,但这显然是我的应用初始化的问题.

在我的初始化中添加以下代码可以解决问题.

# patch werkzeug logging -- not sure why this is being bypassed in werkzeug._internal._log
werkzeug_logger = logging.getLogger('werkzeug')
werkzeug_logger.setLevel(logging.INFO)
