类型错误:预期的 str、bytes 或 os.PathLike 对象，而不是元组 [英] TypeError: expected str, bytes or os.PathLike object, not tuple
问题描述
所以我正在尝试创建一种带有 GUI 的加密程序.代码如下:
So I am trying to create a form of encryption program with a GUI. Here is the code:
import sys
from PyQt4 import QtGui, QtCore
import os
from Crypto.Hash import SHA256
from Crypto import Random
from Crypto.Cipher import AES
class Window(QtGui.QMainWindow):
def __init__(self):
super(Window, self).__init__()
self.setGeometry(50, 50, 500, 300)
self.setWindowTitle("Encryptionprogram")
self.setWindowIcon(QtGui.QIcon('pythonicon.png'))
self.container = QtGui.QWidget()
self.setCentralWidget(self.container)
self.container_lay = QtGui.QVBoxLayout()
self.container.setLayout(self.container_lay)
extractAction = QtGui.QAction("Leave", self)
extractAction.setShortcut("Ctrl+Q")
extractAction.setStatusTip("Leave the app")
extractAction.triggered.connect(self.close_application)
mainMenu = self.menuBar()
fileMenu = mainMenu.addMenu('&File')
fileMenu.addAction(extractAction)
#Inputs
self.Input = QtGui.QLineEdit("Filname", self)
self.Input.setFixedWidth(200)
self.Input.setFixedHeight(25)
self.Input.move(20, 200)
self.Input.setSizePolicy(QtGui.QSizePolicy.Fixed,
QtGui.QSizePolicy.Fixed)
self.Input2 = QtGui.QLineEdit("password", self)
self.Input2.setFixedWidth(200)
self.Input2.setFixedHeight(25)
self.Input2.move(220, 200)
self.Input2.setSizePolicy(QtGui.QSizePolicy.Fixed,
QtGui.QSizePolicy.Fixed)
self.home()
def home(self):
#Enter
self.enter_btn = QtGui.QPushButton("Enter")
self.container_lay.addWidget(self.enter_btn)
self.enter_btn.clicked.connect(self.run1)
self.checkBox = QtGui.QCheckBox('Krypter?', self)
self.checkBox.move(0, 60)
self.checkBox2 = QtGui.QCheckBox('Decrypt', self)
self.checkBox2.move(100, 60)
extractAction = QtGui.QAction(QtGui.QIcon('CloseIcon.png'), 'Close Program', self)
extractAction.triggered.connect(self.close_application)
self.toolBar = self.addToolBar("Extraction")
self.toolBar.addAction(extractAction)
self.show()
def enlarge_window(self, state):
if state == QtCore.Qt.Checked:
self.setGeometry(50, 50, 1250, 600)
else:
self.setGeometry(50, 50, 500, 300)
def close_application(self):
choice = QtGui.QMessageBox.question(self, 'Attention!',
"Close Program?",
QtGui.QMessageBox.Yes | QtGui.QMessageBox.No)
if choice == QtGui.QMessageBox.Yes:
print("Closing...")
sys.exit()
else:
pass
def closeEvent(self, event):
event.ignore()
self.close_application()
def getKey(self, password):
hasher = SHA256.new(password.encode('utf-8'))
return hasher.digest()
def run1(self):
if self.checkBox.isChecked():
Inputfilename = self.Input.text()
Inputpassword = self.Input2.text()
filename = str(Inputfilename)
password = str(Inputpassword)
print(filename, password)
self.encrypt(self.getKey(password), filename)
print("Done.")
else:
print("no work")
def encrypt(self, key, filename):
chunksize = 64 * 1024
outputFile = "(Krypteret)", filename
filesize = str(os.path.getsize(filename)).zfill(16)
IV = Random.new().read(16)
encryptor = AES.new(key, AES.MODE_CBC, IV)
with open(filename, 'rb') as infile:
with open(outputFile, 'wb') as outfile:
outfile.write(filesize.encode('utf-8'))
outfile.write(IV)
while True:
chunk = infile.read(chunksize)
if len(chunk) == 0:
break
elif len(chunk) % 16 != 0:
chunk += b' ' * (16 - (len(chunk) % 16))
outfile.write(encryptor.encrypt(chunk))
def decrypt(self, key, filename):
chunksize = 64 * 1024
outputFile = filename[11:]
with open(filename, 'rb') as infile:
filesize = int(infile.read(16))
IV = infile.read(16)
decryptor = AES.new(key, AES.MODE_CBC, IV)
with open(outputFile, 'wb') as outfile:
while True:
chunk = infile.read(chunksize)
if len(chunk) == 0:
break
outfile.write(decryptor.decrypt(chunk))
outfile.truncate(filesize)
def run():
app = QtGui.QApplication(sys.argv)
GUI = Window()
sys.exit(app.exec_())
run()
但我收到此错误
Traceback (most recent call last):
File "D:/Dokumenter - HDD/Python/GUI.py", line 119, in run1
self.encrypt(self.getKey(password), filename)
File "D:/Dokumenter - HDD/Python/GUI.py", line 134, in encrypt
with open(outputFile, 'wb') as outfile:
TypeError: expected str, bytes or os.PathLike object, not tuple
Closing...
Process finished with exit code 0
我不知道如何解决这个问题，我不仅尝试在互联网上找到解决方案，而且还尝试修复它，只是在出现任何潜在错误后寻找解决方案，但此时我什么也没找到.如果有人可以解释错误和/或提出解决方案，那对我来说意味着整个世界.谢谢！
I dont know how to fix this I have tried to find a solution not only just on the internet but i have also tried to fix it just be lokking after any potential mistakes but at this moment i have found nothing. If anyone could explain the error and/or come with a solution it would mean the world to me. Thanks!
推荐答案
你定义 outputfile 如下:
You define outputfile as follows:
outputFile = "(Krypteret)", filename
这是一个元组，因此是错误的.不清楚你在这里的意思；也许您想在现有文件名前加上(Krypteret)"这个词?在这种情况下你应该这样做
which is a tuple, hence the error. It's not clear what you mean here; perhaps you wanted to prepend the word "(Krypteret)" to the existing filename? In which case you should do
outputFile = "(Krypteret)" + filename
(以后请尽量减少代码.错误完全在encrypt方法内，您应该刚刚发布该方法.)
(In future, please cut your code down to the minimum. The error is entirely within the encrypt method, you should have just posted that method.)
