这个问题与其他有关异常处理的问题略有不同。
我正在尝试使用名为SynoACL的Python模块为Synology NAS上的文件夹设置权限,该模块包含Synology NASes中包含的(其他文档记录不完整的)SynoACLTool:https://github.com/zub2/synoacl
我的代码获取目录中所有子目录的列表。子目录都以AD中的现有用户命名,我试图给予他们对共享其名称的文件夹的修改权限(它们将成为网络上的用户共享)。该脚本会引发错误,但它实际上已成功设置了权限,尽管存在错误。问题是它只对目录中的第一个子目录执行此操作,并且由于该错误而不会继续执行任何其他子目录。我已经尝试将其设置为忽略所有异常,但它仍然失败。这是我的代码和错误,删除了个人信息:
错误:

subprocess.CalledProcessError: Command '['synoacltool', '-add', '.', 'user:DOMAINNAME\\username:allow:rwxpd-aARWc--:fd--']' returned non-zero exit status 255
代码:
import os
from synoacl.tool import SynoACL, SynoACLTool
user_share_path = '/path/to/share/'
permTemplate1 = "user:DOMAINNAME\\"
permTemplate2 = ":allow:rwxpd-aARWc--:fd--"
os.chdir(user_share_path)
cwd = os.getcwd()
print(cwd)
folderList = os.listdir()
try:
for folderName in folderList:
os.chdir(folderName)
cwd = os.getcwd()
print(cwd)
folderPermString = permTemplate1 + folderName + permTemplate2
print(folderPermString)
SynoACLTool.add(".", SynoACL.fromString(folderPermString))
os.chdir("..")
except:
pass
由于添加了try和except行,它不会再抛出任何错误,但它会在第一个循环后停止。有没有办法让它继续执行循环,尽管有错误?
编辑:评论建议将try放入for循环中,似乎没有修复它:
for folderName in folderList:
try:
os.chdir(folderName)
cwd = os.getcwd()
print(cwd)
folderPermString = permTemplate1 + folderName + permTemplate2
print(folderPermString)
SynoACLTool.add(".", SynoACL.fromString(folderPermString))
os.chdir("..")
except:
pass
答案 0 :(得分:0)
将try / except块放在for循环中:
for folderName in folderList:
try:
os.chdir(folderName)
cwd = os.getcwd()
print(cwd)
folderPermString = permTemplate1 + folderName + permTemplate2
print(folderPermString)
SynoACLTool.add(".", SynoACL.fromString(folderPermString))
os.chdir("..")
except:
pass
你也可以这样做(如果你不想做任何关于捕获异常的事情)
# contextlib module
from contextlib import suppress
with suppress(Exception):
os.chdir(folderName)
cwd = os.getcwd()
print(cwd)
folderPermString = permTemplate1 + folderName + permTemplate2
print(folderPermString)
SynoACLTool.add(".", SynoACL.fromString(folderPermString))
os.chdir("..")
答案 1 :(得分:0)
替换此行
except:
通过
except Exception as ex:
所以:
import os
from builtins import Exception
user_share_path = '/path/to/share/'
permTemplate1 = "user:DOMAINNAME\\"
permTemplate2 = ":allow:rwxpd-aARWc--:fd--"
os.chdir(user_share_path)
cwd = os.getcwd()
print(cwd)
folderList = os.listdir()
for folderName in folderList:
try:
os.chdir(folderName)
cwd = os.getcwd()
print(cwd)
folderPermString = permTemplate1 + folderName + permTemplate2
print(folderPermString)
SynoACLTool.add(".", SynoACL.fromString(folderPermString))
os.chdir("..")
except Exception as ex:
print(ex)
pass
