您可以使用base64编码将图像转换为字符串形式，并将其作为Lambda函数的输出返回。然后，在客户端接收到该字符串后，使用相应的解码器将其转换回图像。以下是示例代码：

Lambda函数:

import base64

def lambda_handler(event, context): with open("image.png", "rb") as image_file: encoded_string = base64.b64encode(image_file.read()) return { "statusCode": 200, "headers": {"Content-Type": "application/json"}, "body": encoded_string.decode('utf-8') }

客户端:

import base64 import requests

response = requests.get("<>") image_data = base64.b64decode(response.content) with open("received_image.png", "wb") as received_image: received_image.write(image_data)
