watchdog應用實例

實例：監測某文件夾，一旦文件夾里有文件，就把它剪切到其他服務器

import sys import os, shutil import time import logging from watchdog.observers import Observer from watchdog.events import (LoggingEventHandler, FileSystemEventHandler)backupDir = 'D:/Work/backup' baseDir = 'S:/Test/Upload'def copyFile(fromFile, toDir):if os.path.isdir(fromFile):clearDir = fromFile[len(baseDir):]try:os.makedirs(toDir + clearDir)print 'NewFolder: ', fromFile.encode('utf-8'), ' ===> ', (toDir + fromFile[len(baseDir):]).encode('utf-8')except:print 'NewFolder-PASS:', fromFile.encode('utf-8')returnelse:clearDir = os.path.dirname(fromFile)[len(baseDir):]if not os.path.isdir(toDir + clearDir):os.makedirs(toDir + clearDir)try:time.sleep(0.2)shutil.move(fromFile, toDir + fromFile[len(baseDir):])print 'MoveFile: ', fromFile.encode('utf-8'), ' ===> ', (toDir + fromFile[len(baseDir):]).encode('utf-8')except:print 'MoveFile-PASS:', fromFile.encode('utf-8')returnreturnclass TestEventHandler(FileSystemEventHandler):def on_any_event(self, event):# print("event noticed: " + event.event_type + # " on file " + event.src_path.encode('utf-8') + " at " + time.asctime())passdef __init__(self, pattern='*'):self.pattern = patterndef on_moved(self, event):print ("moved src path:"+ event.src_path.encode('utf-8'))print ("moved dest path:"+ event.dest_path)copyFile(event.dest_path, backupDir)def on_created(self, event):print ("created path:"+ event.src_path.encode('utf-8'))copyFile(event.src_path, backupDir)def on_deleted(self, event):print ("deleted path:"+ event.src_path.encode('utf-8'))def should_reload(self, event):if isinstance(event, FileSystemMovedEvent):return Truereturn Falsedef on_modified(self, event):print ("modified path:"+ event.src_path.encode('utf-8'))copyFile(event.src_path, backupDir)if __name__ == "__main__":logging.basicConfig(level=logging.INFO,format='%(asctime)s - %(message)s',datefmt='%Y-%m-%d %H:%M:%S')# path = sys.argv[1] if len(sys.argv) > 1 else '.'# event_handler = LoggingEventHandler()event_handler = TestEventHandler()observer = Observer()observer.schedule(event_handler, baseDir, recursive=True)observer.start()try:while True:time.sleep(1)except KeyboardInterrupt:observer.stop()observer.join()

補充一點：程序最終的效果，監測文件夾一旦有文件，就立馬剪切到備份路徑下，但是檢測位置里的文件夾將不會被刪除
