将 JSON 文件转换为二维码时出错

Question

我正在尝试使用 pyqrcode

将 json 文件转换为二维码

import tkinter as tk
from tkinter import filedialog
import json
import pyqrcode as qrcode

root= tk.Tk()
root.title('Convertitore CSV in JSON')

canvas1 = tk.Canvas(root, width = 300, height = 300, bg = 'lightsteelblue2', relief = 'raised')
canvas1.pack()

label1 = tk.Label(root, text='Tool Conversione File', bg = 'lightsteelblue2')
label1.config(font=('helvetica', 20))
canvas1.create_window(150, 60, window=label1)

def json_to_qrcode(jsonFilePath2, imageFilePath):
    with open(jsonFilePath2, 'w', encoding='utf-8') as jsonf:
        jsonReader = json.load(jsonf)
         
        qr = qrcode.QRCode(version = 1, box_size = 15, border = 5)
        data = jsonReader
        qr.add_data(data)
        qr.make(fit = True)
        img = qr.make_image(fill = 'black', back_color = 'white')
        img.save('Dieta.png')
        
jsonFilePath2 = filedialog.askopenfilename()
imageFilePath = filedialog.asksaveasfilename(mode='w', defaultextension=".png")

browseButton_CSV = tk.Button(text="     Importa JSON File     ", command=json_to_qrcode(jsonFilePath2, imageFilePath), bg='green', fg='white', font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 130, window=browseButton_CSV)

root.mainloop()

这里是 JSON 文件的示例：

[
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Fette biscottate",
        "Quantita": "3",
        "UDM": "fette",
        "Note": ""
    },
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Latte",
        "Quantita": "200",
        "UDM": "g",
        "Note": ""
    }
]

当我尝试运行代码时，它给我这个错误：“TclError：错误的选项“-mode”：必须是 -confirmoverwrite，-defaultextension，-filetypes，-initialdir，-initialfile， -parent、-title 或 -typevariable

我该如何解决？提前致谢。

你能试试下面的代码吗？我想你的问题现在应该已经解决了。

请安装枕头库。（pip 安装枕头）

问题

您正试图为 filedialog.asksaveasfilename() 函数传递错误的参数。

您正在使用 pyqrcode 而不是 qrcode。（您已经编写了有关二维码库的代码）

 import tkinter as tk
 from tkinter import filedialog
 import json
 import qrcode

 root = tk.Tk()
 root.title('Convertitore CSV in JSON')

 canvas1 = tk.Canvas(root, width=300, height=300, bg='lightsteelblue2', relief='raised')
 canvas1.pack()

 label1 = tk.Label(root, text='Tool Conversione File', bg='lightsteelblue2')
 label1.config(font=('helvetica', 20))
 canvas1.create_window(150, 60, window=label1)


 def json_to_qrcode(jsonFilePath2, imageFilePath):
     with open(jsonFilePath2, 'r') as jsonf:
       jsonReader = json.load(jsonf)

       qr = qrcode.QRCode(version=1, box_size = 15, border = 5)
       data = jsonReader
       qr.add_data(data)
       qr.make(fit=True)
       img = qr.make_image(fill='black', back_color='white')
       img.save('Dieta.png')


jsonFilePath2 = filedialog.askopenfilename()
imageFilePath = filedialog.asksaveasfilename()

browseButton_CSV = tk.Button(text="     Importa JSON File     ", 
command=json_to_qrcode(jsonFilePath2, imageFilePath),
                          bg='green', fg='white', font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 130, window=browseButton_CSV)

root.mainloop()
