在Django中图像不能转换为64进制

import base64

# 将图像文件转换为Base64编码字符串
def image_to_base64(image_path):
    with open(image_path, "rb") as image_file:
        encoded_string = base64.b64encode(image_file.read()).decode("utf-8")
    return encoded_string

# 将Base64编码字符串转换为图像文件
def base64_to_image(base64_string, image_path):
    with open(image_path, "wb") as image_file:
        image_file.write(base64.b64decode(base64_string))

# 使用示例
image_path = "path/to/image.jpg"
base64_string = image_to_base64(image_path)
print(base64_string)

# 将Base64编码字符串转换为图像文件
new_image_path = "path/to/new_image.jpg"
base64_to_image(base64_string, new_image_path)
