Python 尝试将FCM CCS服务器与sleekxmpp连接时出错

我正在尝试使用sleekxmpp 1.3.1构建一个非常简单的python3程序，该程序将能够连接Firebase云消息服务器。我在读取XML流时遇到了一个奇怪的

错误，下面的代码有问题。我怎样才能修好它

我们可以从控制台输出中看到STARTTLS已启用。除了禁用它，我没有找到其他方法，但它并没有解决这个错误

根据，发送的第一条消息似乎有效，但仍然显示“从xml流读取错误”

python代码

我找到了答案。将“use\u tls=True”替换为“use\u ssl=True”，效果会更好。
为了完整起见，这将是一个工作实现的示例：

import logging
import socket
import json
import uuid

logging.basicConfig(level=logging.DEBUG, format="%(levelname)7s %(module)12s:%(lineno)-4s %(message)s")

FCM_SERVER_URL = "fcm-xmpp.googleapis.com"
FCM_SERVER_PORT = 5236
FCM_SERVER_KEY = "XXXXXXXXXXX" # <- Your Server Key
FCM_SENDER_ID = "XXXXXXXXXXX" # <- Your Sender ID
FCM_JID = FCM_SENDER_ID + "@gcm.googleapis.com"
FCM_SERVER_IP = socket.gethostbyname(FCM_SERVER_URL)
TOPIC = "/topics/info"

body = {
    "to": TOPIC, 
    "message_id": uuid.uuid4().hex,
    "data": { "msg": "This is the content"}
}
message = "<message><gcm xmlns='google:mobile:data'>"+json.dumps(body)+"</gcm></message>"

        self.process(block=True)
    def start(self, event):
        self.send_raw(message)
