问题描述
限时送ChatGPT账号..我正在编写一个程序,根据提供的消息和密码生成加密的 qr,但它一直返回相同的错误.
I'm making a program to generate an encrypted qr from the message and password provided, but it keeps on returning the same error.
我尝试将值传递给其他变量
I tried passing the value to other variables
main.py
from tkinter import *
import crypt
root=Tk()
root.title("QR Crypt")
root.geometry("800x600+0+0")
heading = Label(root, text="QR Code Encrypt", font=("arial",54,"bold"), fg="steelblue").pack()
label1 = Label(root, text="MESSAGE: ", font=("arial",24,"bold"), fg="black").place(x=10,y=200)
label2 = Label(root, text="PASSWORD: ", font=("arial",24,"bold"), fg="black").place(x=10,y=300)
message = StringVar()
entry_box = Entry(root, textvariable=message, width=80, bg="lightgreen").place(x=280, y=210)
passwd = StringVar()
entry_box = Entry(root, textvariable=passwd, width=30, bg="lightgreen").place(x=280, y=310)
def generate_qr():
crypt.crypt_f(passwd,message)
canvas = Canvas(root, width = 300, height = 300)
canvas.pack()
img = PhotoImage(file="myqr.svg")
canvas.create_image(20,20, anchor=NW, image=img)
work = Button(root, text="Generate", width=30, height=5, bg="lightblue", command=generate_qr).place(x=250,y= 400)
mainloop()

qrcode.py
from pyqrcode import *
def qr_ready(qr_rcvd):
toqr=qr_rcvd
qrcode = create(toqr)
qrcode.svg("myqr.svg",scale=10)
我希望它返回另一个画布中的二维码,但它返回错误:
I expect it to return the QR code in another canvas but it is returning the error:
AttributeError: 'StringVar' 对象没有属性 'encode'
AttributeError: 'StringVar' object has no attribute 'encode'
