我在提交有效网址后收到此错误消息。

Traceback (most recent call last)

    raise ConnectionError(self._error_message(e))

    ConnectionError: Error 111 connecting localhost:6379. Connection refused.

错误消息表明localhost：6379有问题代码的相关部分在这里：

def create_app(redis_host='localhost', redis_port=6379, with_static=True):
    app = Shortly({
        'redis_host':       redis_host,
        'redis_port':       redis_port
    })
    if with_static:
        app.wsgi_app = SharedDataMiddleware(app.wsgi_app, {
            '/static':  os.path.join(os.path.dirname(__file__), 'static')
        })
    return app

if __name__ == '__main__':
    from werkzeug.serving import run_simple
    app = create_app()
    run_simple('127.0.0.1', 5000, app, use_debugger=True, use_reloader=True)

这当然意味着服务器在localhost：5000上运行。那么为什么create_app函数中还有另一个端口号呢？这让我感到困惑。

我不熟悉或不熟悉，但看起来你错过了redis服务器，使用你最喜欢的软件包管理器安装一个，然后再试一次。

在遵循Werkzeug教程＆＃34;很快＆＃34;之后出现错误111
