我正在使用WebSocket通过API网关发送JPG图像。因为我需要在另一台机器上的真实的图像。
我按照这篇关于WebSocket API设置的文章，添加了一个单独的路由sendMessage，它调用Lambda函数
Setup a basic WebSocket mock in AWS ApiGateway
这是在Lambda上运行的代码示例

import base64
import boto3

api_client = boto3.client('apigatewaymanagementapi',endpoint_url='https://../test')
while not loaded:
    with open("/tmp/image.jpg", "rb") as image:
        b64string = base64.b64encode(image.read())
        firstpart, secondpart = b64string[:len(b64string)//2], b64string[len(b64string)//2:]
        api_client.post_to_connection(ConnectionId=connectionId, Data=firstpart)
        api_client.post_to_connection(ConnectionId=connectionId, Data=secondpart)
api_client.post_to_connection(ConnectionId=connectionId, Data="connected successfully!")

这个在机器上

from websockets.sync.client import connect
import base64
from PIL import Image

with connect("wss...") as websocket:
    websocket.send(json.dumps({"action":"sendMessage","message":"scanning"}))
    while (b64image_string_1:=websocket.recv()) != "connected successfully!":
        b64image_string_2 =websocket.recv()
        b64image_string = b64image_string_1 + b64image_string_2

        f = io.BytesIO(base64.b64decode(b64image_string))
        img = Image.open(f)

虽然图像最初会被发送过来，但在它运行几秒钟后我会得到一个错误。
botocore.errorfactory.GoneException: An error occurred (GoneException) when calling the PostToConnection operation:
我猜我的WebSocket设置可能是导致错误的原因，但我不确定如何修复它。
