重命名看门狗中正在监视的文件会产生 on_moved 事件触发器。我遇到的问题是无法判断文件被移动/重命名为什么（因为 on_moved 事件触发器也会在文件重命名时发生）。有没有办法将它内置到看门狗中，或者我应该在我正在编写的程序中构建一个解决方法？

这是一些示例代码

#!/usr/bin/python

import sys
import time

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

'''
Extend FileSystemEventHandler to be able to write custom on_any_event method
'''
class MyHandler(FileSystemEventHandler):
    '''
    Overwrite the methods for creation, deletion, modification, and moving
    to get more information as to what is happening on output
    '''
    def on_created(self, event):
        print("created: " + event.src_path)

    def on_deleted(self, event):
        print("deleted: " + event.src_path)

    def on_modified(self, event):
        print("modified: " + event.src_path)

    def on_moved(self, event):
        print("moved/renamed: " + event.src_path)


watch_directory = sys.argv[1]       # Get watch_directory parameter

event_handler = MyHandler()

observer = Observer()
observer.schedule(event_handler, watch_directory, True)
observer.start()

'''
Keep the script running or else python closes without stopping the observer
thread and this causes an error.
'''
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    observer.stop()
observer.join()

每当事件发生时，代码都会打印出来，发生的事件类型以及文件/文件夹的路径。它需要一个参数，即要监视的文件夹的路径。

如果您不知道对象print dir(obj)在您的情况下刚刚在此处执行的方法和属性是什么，event.dest_path则可以完成工作
