python GUI查看baidumap实现代码

以下是一个使用Python GUI（tkinter）实现在百度地图上查看指定地址的代码示例：

import tkinter as tk
import requests
from io import BytesIO
from PIL import Image, ImageTk

# 百度地图API AK（需要自己去百度地图开发者中心申请）
AK = "your_ak_here"

class MapView(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)
        self.parent = parent
        self.address_var = tk.StringVar()
        self.address_var.set("北京市海淀区中关村")
        self.create_widgets()

    def create_widgets(self):
        # 地址输入框
        address_label = tk.Label(self, text="地址：")
        address_label.grid(row=0, column=0, padx=5, pady=5)
        address_entry = tk.Entry(self, textvariable=self.address_var)
        address_entry.grid(row=0, column=1, padx=5, pady=5)

        # 搜索按钮
        search_button = tk.Button(self, text="搜索", command=self.search_address)
        search_button.grid(row=0, column=2, padx=5, pady=5)

        # 地图显示区域
        self.map_canvas = tk.Canvas(self, bg="white", width=600, height=400)
        self.map_canvas.grid(row=1, column=0, columnspan=3, padx=5, pady=5)

    def search_address(self):
        address = self.address_var.get()
        # 构造百度地图API请求URL
        url = f"http://api.map.baidu.com/geocoding/v3/?address={address}&output=json&ak={AK}"
        response = requests.get(url)
        result = response.json()
        # 解析返回结果获取经纬度
        location = result["result"]["location"]
        lat, lng = location["lat"], location["lng"]
        # 构造静态地图API请求URL
        url = f"http://api.map.baidu.com/staticimage/v2?ak={AK}&center={lng},{lat}&width=600&height=400&zoom=16"
        response = requests.get(url)
        # 将返回的图片数据转换为PIL Image对象并显示在Canvas上
        img = Image.open(BytesIO(response.content))
        img = ImageTk.PhotoImage(img)
        self.map_canvas.create_image(0, 0, anchor="nw", image=img)
        self.map_canvas.image = img

if __name__ == "__main__":
    root = tk.Tk()
    root.title("Baidu Map View")
    root.geometry("610x440+100+100")
    MapView(root).pack(expand=True, fill="both")
    root.mainloop()

这个程序会在GUI界面中显示一个输入框和一个按钮，用户可以在输入框中输入要查看的地址，然后点击按钮，程序会调用百度地图API获取该地址的经纬度，并将其作为静态地图API的参数，从而获取包含该地址位置的地图图片，并将其显示在GUI界面中。
