目录监控中的看门狗不工作

watchdog in directory monitoring is not working

我想监视文件夹的文件添加、修改和删除,并在发生任何此类事件时执行命令。

我发现这个教程对我有帮助 https://www.michaelcho.me/article/using-pythons-watchdog-to-monitor-changes-to-a-directory 所以这是我现在拥有的代码

import time
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler



class Watcher:
    DIRECTORY_TO_WATCH = "/Users/***/desktop/google drive/protpics"


    def __init__(self):
        self.observer = Observer()


    def run(self):
        event_handler = Handler()
        self.observer.schedule(event_handler, self.DIRECTORY_TO_WATCH, recursive=True)
        self.observer.start()
        try:

           while True:
               time.sleep(5)

        except:
            self.observer.stop()
            print("Error")

        self.observer.join()


class Handler(FileSystemEventHandler):

    @staticmethod
    def on_my_event(event):
        if event.is_directory:
            return None

        elif event.event_type == 'created':
           #Take any action here when a file is first created.
           print ("Recived created event - %s" % event.src_path)

        elif event.event_type == 'modified':
            # Take any action here when a file is modified.
            print ("Recieved modified event - %s" % event.src_path)


if __name__ == '__main__':
    W = Watcher()
    W.run()

现在的问题是,当我将新文件添加到目录时,没有打印出任何消息。我做错了什么,我该如何解决?

你不能找出你的代码和示例代码之间的区别吗?在你的link中,作者使用on_any_event,而你使用的是on_my_event。没有名为 on_my_event.

的方法
