Python 命令行教程
首先,我将展示如何从 Python 命令行使用 kwallet 来读取和写入密码:
$ python
# We import the necessary modules.
>>> from PyKDE4.kdeui import KWallet
>>> from PyQt4 import QtGui
# We create a QApplication. We will not use it, but otherwise
# we would get a "QEventLoop: Cannot be used without
# QApplication" error message.
>>> app = QtGui.QApplication([])
# We open the wallet.
>>> wallet = KWallet.Wallet.openWallet(
KWallet.Wallet.LocalWallet(), 0)
# We create a folder in which we will store our password,
# and set it as current.
>>> wallet.createFolder('myfolder')
True
>>> wallet.hasFolder('myfolder')
True
>>> wallet.setFolder('myfolder')
True
# We read the password (which does not exist yet), write it,
# and read it again.
>>> wallet.readPassword('mykey')
(0, PyQt4.QtCore.QString(u''))
>>> wallet.writePassword('mykey', 'mypassword')
0
>>> wallet.readPassword('mykey')
(0, PyQt4.QtCore.QString(u'mypassword'))
作为 Python 模块的教程
通常你想创建一些简单的函数来包装 kwallet 方法。以下 Python 模块可以打开钱包,获取和设置密码:
#!/usr/bin/python
from PyKDE4.kdeui import KWallet
from PyQt4 import QtGui
def open_wallet():
app = QtGui.QApplication([])
wallet = KWallet.Wallet.openWallet(
KWallet.Wallet.LocalWallet(), 0)
if not wallet.hasFolder('kwallet_example'):
wallet.createFolder('kwallet_example')
wallet.setFolder('kwallet_example')
return wallet
def get_password(wallet):
key, qstr_password = wallet.readPassword('mykey')
# converting the password from PyQt4.QtCore.QString to str
return str(qstr_password)
def set_password(wallet, password):
wallet.writePassword('mykey', password)
它可以通过以下方式使用:
$ python
>>> import kwallet_example
>>> wallet = kwallet_example.open_wallet()
>>> kwallet_example.set_password(wallet, 'mypass')
>>> kwallet_example.get_password(wallet)

好吧,我在这里找到了一个很好的例子,你还需要使用 PyKDE4,而不仅仅是 PyQt。
