如何在没有js的情况下在Flask中获取不同的图像？

from flask import Flask, request, send_file
from PIL import Image

app = Flask(__name__)

@app.route('/get_image')
def get_image():
    image_name = request.args.get('image_name')  # 获取图像名称参数
    if image_name == 'image1':
        image_path = 'path_to_image1.jpg'  # 图像1的文件路径
    elif image_name == 'image2':
        image_path = 'path_to_image2.jpg'  # 图像2的文件路径
    else:
        return 'Invalid image name'

    image = Image.open(image_path)  # 使用PIL库读取图像文件
    return send_file(image_path, mimetype='image/jpeg')  # 返回图像文件作为响应

if __name__ == '__main__':
    app.run()
