在使用tkinter制作的应用程序中打开并另存为用户设置的Json配置文件

import tkinter as tk
from tkinter import filedialog
import json

root = tk.Tk()

def open_json_file():
    file_path = filedialog.askopenfilename(filetypes=[("JSON Files", "*.json")])
    if file_path:
        with open(file_path, "r") as file:
            json_data = json.load(file)
            # 在这里可以对json_data进行处理或使用

def save_json_file():
    file_path = filedialog.asksaveasfilename(defaultextension=".json", filetypes=[("JSON Files", "*.json")])
    if file_path:
        with open(file_path, "w") as file:
            # 在这里可以构建要保存的json_data
            json.dump(json_data, file, indent=4)

open_button = tk.Button(root, text="打开", command=open_json_file)
open_button.pack()

save_button = tk.Button(root, text="另存为", command=save_json_file)
save_button.pack()

root.mainloop()
