如何在Tkinter中显示图像(来自URL)

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

root = tk.Tk()
root.title("显示图像")

def show_image(url):
    response = requests.get(url)
    image = Image.open(BytesIO(response.content))
    photo = ImageTk.PhotoImage(image)
    label = tk.Label(root, image=photo)
    label.image = photo  # 保持引用，防止垃圾回收
    label.pack()

image_url = "https://example.com/image.jpg"  # 替换为实际的图像URL
show_image(image_url)

root.mainloop()
