Python Watchdog - src_path 不一致 [英] Python Watchdog - src_path inconsistent

问题描述

我正在尝试编写一个脚本来监视特定的日志文件以进行修改，但我无法让它看到任何 .txt 文件.它适用于其他类型的文件.

I'm trying to write a script that watches a specific log file for modification, but I can't get it to see any .txt files. It works fine with other types of files.

from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
from os.path import expanduser

file_to_watch = 'test.txt'

class FileModifiedHandler(FileSystemEventHandler):

    def __init__(self, path, file_name, callback):
        self.file_name = file_name
        self.callback = callback

        self.observer = Observer()
        self.observer.schedule(self, path, recursive=False)
        self.observer.start()
        self.observer.join()

    def on_modified(self, event): 

        print "Event: %s" % (event)
        print "Ends with %s: %s" % (self.file_name, event.src_path.endswith(self.file_name))

        if not event.is_directory and event.src_path.endswith(self.file_name):
            self.callback()

if __name__ == '__main__':


    def callback():
        print("FILE WAS MODIFIED")

    FileModifiedHandler('.', file_to_watch, callback)

当我将 file_to_watch 设置为 .py 文件时，日志返回正确的源路径，但是当我将其更改为同一文件夹中的 .txt 文件时，它会停在该目录中.我不确定这是什么原因.这是程序返回的内容:

When I set file_to_watch to a .py file, the log returns the correct source path, but when I change it to a .txt file in the same folder, it stops at the directory. I'm not sure what the reason for this is. Here is what the program returns:

Event: <FileModifiedEvent: src_path='/Users/nick/Documents/Python/WatchdogTest.py'>
Ends with WatchdogTest.py: True
FILE WAS MODIFIED

Event: <DirModifiedEvent: src_path='/Users/nick/Documents/Python'>
Ends with test.txt: False

推荐答案

can you rename file test.txt to some other name say mytest.txt 我觉得/t 被区别对待，或者您可以添加转义序列以绕过.

can you rename file test.txt to some other name say mytest.txt I feel like /t is treated differently or may be you can add escape sequence to bypass.
