无法编组响应：“utf-8”编解码器无法解码 position 中的字节 0xc8 48：连续字节无效

Question

我正在尝试在 AWS Lambda 上使用此代码，它显示此错误： Unable to marshal response: 'utf-8' codec can't decode byte 0xc8 in position 48: invalid continuation byte ，我试图在 True 之间更改 isBase64Encoded和 False 但错误仍然发生，不知道。

import requests

def lambda_handler(event, context):

    video_data = requests.get("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4", stream=True)
    video_content = video_data.content
    response = {
        "statusCode": 200,
        "headers": {
            "Content-Type": "video/mp4",
            "Content-Length": len(video_content)
        },
        "body": video_content,
        "isBase64Encoded": False
    }
    return response

完整错误：

Response
{
  "errorMessage": "Unable to marshal response: 'utf-8' codec can't decode byte 0xc8 in position 48: invalid continuation byte",
  "errorType": "Runtime.MarshalError",
  "stackTrace": []

Answer 1

也许那是因为你必须对视频进行编码

import base64
encoded_video_content = base64.b64encode(video_content).decode()

然后在响应中将其更改为以下内容

  response = {
    "statusCode": 200,
    "headers": {
        "Content-Type": "video/mp4"
    },
    "body": encoded_video_content,
    "isBase64Encoded": True
}
