Python-tkinter界面设计案例---快捷编辑json文件

前言：为了方便测试员编辑一些json文件信息，我打算提供一个简洁清晰的ui界面来提高工作效率。该ui基于轻量化tkinter实现。大致效果如下图所示：

前置环境：python3

import tkinter as tk
from tkinter import messagebox
import json
import os
import _locale
_locale._getdefaultlocale = (lambda *args: ['zh_CN', 'utf8'])
# 配置文件路径
CONFIG_FILE = '..\Config\presentation.json'
CONFIG_FILE2 = '..\Config\stage_test_case.json'

CONFIG_FILE和CONFIG_FILE2为需要读取的json文件，路径可根据自身情况来修改。关于json文件的读写如下：

def save_config():#指定需要更改的json元素并获取保存
    config = {
        "start_command": homepage_connect.get(),
        "details_command": details_connect.get()
    }
    with open(CONFIG_FILE2, 'r', encoding='UTF-8') as file:
        config2 = json.load(file)
    config2['case400']['caseSettings']['robot_task'] = homepage_slide.get()
    config2['case401']['caseSettings']['robot_task'] = details_slide.get()
    config2['case402']['caseSettings']['robot_task'] = details20s_slide.get()
    config2['case403']['caseSettings']['robot_task'] = menu_slide.get()

    try:
        with open(CONFIG_FILE, 'w', encoding='UTF-8') as file:
            json.dump(config, file, ensure_ascii=False, sort_keys=False, indent=2)
            messagebox.showinfo("成功", "接口配置已成功保存")
        with open(CONFIG_FILE2, 'w', encoding='UTF-8') as file:
            json.dump(config2, file, ensure_ascii=False, sort_keys=False, indent=2)
            messagebox.showinfo("成功", "文件配置已成功保存")
    except Exception as e:
        messagebox.showerror("错误", f"保存失败: {e}")


def load_config():#读取json文件
    if os.path.exists(CONFIG_FILE):
        try:
            with open(CONFIG_FILE, 'r', encoding='UTF-8') as file:
                config = json.load(file)
                homepage_connect.delete(0, tk.END)
                homepage_connect.insert(0, config.get('start_command', ''))
                details_connect.delete(0, tk.END)
                details_connect.insert(0, config.get('details_command', ''))
                messagebox.showinfo("成功", "接口配置已成功加载")
        except Exception as e:
            messagebox.showerror("错误", f"加载失败: {e}")
    if os.path.exists(CONFIG_FILE2):
        try:
            with open(CONFIG_FILE2, 'r', encoding='UTF-8') as file:
                config2 = json.load(file)
                homepage_slide.delete(0, tk.END)
                homepage_slide.insert(0, config2['case400']['caseSettings'].get('robot_task', ''))
                details_slide.delete(0, tk.END)
                details_slide.insert(0, config2['case401']['caseSettings'].get('robot_task', ''))
                details20s_slide.delete(0, tk.END)
                details20s_slide.insert(0, config2['case402']['caseSettings'].get('robot_task', ''))
                menu_slide.delete(0, tk.END)
                menu_slide.insert(0, config2['case403']['caseSettings'].get('robot_task', ''))
                messagebox.showinfo("成功", "文件配置已成功加载")
        except FileNotFoundError:
            messagebox.showwarning("警告", "配置文件不存在")
        except Exception as e:
            messagebox.showerror("错误", f"加载失败: {e}")

创建窗口来调用上述函数实现交互：

# 创建主窗口
root = tk.Tk()
root.title("演示模式接口命令配置工具")

# 创建一个文本框用于输入启动命令
start_command_label = tk.Label(root, text="演示模式主页接口:")
start_command_label.pack(pady=5)
homepage_connect = tk.Entry(root, width=80)
homepage_connect.pack(pady=5)

# 创建一个文本框用于输入详情页命令
details_command_label = tk.Label(root, text="演示模式详情页接口:")
details_command_label.pack(pady=5)
details_connect = tk.Entry(root, width=80)
details_connect.pack(pady=5)


# 创建一个文本框用于输入另一个启动命令
another_start_command_label = tk.Label(root, text="演示模式主页，修改末尾竖滑为1横滑为2:")
another_start_command_label.pack(pady=5)
homepage_slide = tk.Entry(root, width=80)
homepage_slide.pack(pady=5)

# 创建一个文本框用于输入详情页滑动命令
another_details_command_label = tk.Label(root, text="演示模式详情页，修改末尾竖滑为1横滑为2:")
another_details_command_label.pack(pady=5)
details_slide = tk.Entry(root, width=80)
details_slide.pack(pady=5)

# 创建一个文本框用于输入详情页20s滑动命令
another_details_command_label = tk.Label(root, text="演示模式详情页20s，修改末尾竖滑为1横滑为2:")
another_details_command_label.pack(pady=5)
details20s_slide = tk.Entry(root, width=80)
details20s_slide.pack(pady=5)

# 创建一个文本框用于输入详情页20s滑动命令
another_details_command_label = tk.Label(root, text="演示模式菜单栏详情页，修改末尾竖滑为1横滑为2:")
another_details_command_label.pack(pady=5)
menu_slide = tk.Entry(root, width=80)
menu_slide.pack(pady=5)

# 创建一个按钮用于保存配置
save_button = tk.Button(root, text="保存配置", command=save_config)
save_button.pack(pady=10)

# 创建一个按钮用于加载配置
load_button = tk.Button(root, text="加载配置", command=load_config)
load_button.pack(pady=10)

# 加载初始配置
load_config()

# 运行主循环
root.mainloop()
