循环遍历目录中的所有图像并转换为base64

import os
import base64

def convert_images_to_base64(directory):
    image_data = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            if is_image_file(file_path):
                with open(file_path, 'rb') as f:
                    image_bytes = f.read()
                    base64_data = base64.b64encode(image_bytes).decode('utf-8')
                    image_data.append(base64_data)
    return image_data

def is_image_file(file_path):
    image_extensions = ['.jpg', '.jpeg', '.png', '.gif']
    file_extension = os.path.splitext(file_path)[1].lower()
    return file_extension in image_extensions

# 示例用法
directory = '/path/to/images'
image_data = convert_images_to_base64(directory)
print(image_data)
