该程序应该问您一个链接，该链接由于代码中的某些事情而被转换为QRCode

Question

该程序应该向用户询问一个输入，该输入将稍后用于创建QR码。有一个不起作用的按钮应该创建该QR码。之后，还有另一个按钮应该打开该QR码作为图像。

由于某种原因，我无法理解如何使用用户提供的输入。另外，QR码是在我什至做任何事情之前生成的。

import qrcode 
import tkinter
from PIL import Image



main = tkinter.Tk("Link converter to QrCode ")
main.title("Link converter to Qr Code")
main.geometry("685x85")

#This is used just for what the person should write on the side
link = tkinter.Label(
    main, 
    width="30",
    text=('Link:'))
link.grid(row=0)

#this entry is supposed to receive an input that will later be used
e1 = tkinter.Entry(
    main, 
    bd="5", 
    width="75",
    text=(""))
e1.grid(row=0, column=1)

#This is what should be getting the input from above
def retrieve_input():
    input = main.e1.get("1.0")
x=input



#This button is supposed to create the qrcode with the input given above
button_create = tkinter.Button(
    main, 
    text="Click to create the Qrcode.", 
    command = lambda: qrcode.make(x))
button_create.grid(row=2, column=1)

img = qrcode.make()
img.save ("Qrcode.png")



#This button should open the image of the qrcode
button_open = tkinter.Button ( 
    main,  
    text="Click here to open the Qrcode", 
    command = lambda: Image.open(open("Qrcode.png", "rb")),
    width="25")
button_open.grid(row=2, column=0)


#This button is working and is just to close the program
exit_button = tkinter.Button(
    main,
    width=("15"),
    text='Exit',
    command= lambda: main.quit())
exit_button.grid(row=3, column=0)


main.mainloop()

获取条目的值，并将其用作参数qrcode.make（）。

将此代码放入retirevie_input（）函数中，然后从按钮调用该代码。

#This is what should be getting the input from above
def retrieve_input():
    img = qrcode.make(e1.get())
    img.save("Qrcode.png")

#This button is supposed to create the qrcode with the input given above
button_create = tkinter.Button(
    main,
    text="Click to create the Qrcode.",
    command = retrieve_input)
button_create.grid(row=2, column=1)
