我试图在python中创建一个discord bot，但discord.py没有给予我所需的控制级别，因此我正在创建一个自定义API。我正在使用“websocket-client”模块。我已经看过discord的文档了，我找不到问题。由于某种原因，当我运行这段代码时，它给了我一个错误：

import requests
from websocket import create_connection
import json
import time
from threading import Thread

token = "<my token>"

class DiscordBot:
    def __init__(self, token):
        self.token = token
        self.header = {"authorization": token, "content-type":"application/json"}

    def connect(self):
        self.ws = create_connection("wss://gateway.discord.gg/?v=9&encoding=json")
        event = self.__recievejsonresponse__()
        self.heartbeat_interval = event["d"]["heartbeat_interval"]/1000
        heartbeatProc = Thread(target=self.heartbeat)
        heartbeatProc.start()
        payload = {
            "op":2,
            "d":{
                "token":self.token,
                "intents":8,

                "properties":{
                    "os":"linux",
                    "browser":"chromium",
                    "device":"pc"
                },
            }
        }
        self.__sendjsonrequest__(payload)
        self.__recieveloop__()
    
    def __recieveloop__(self):
        while True:
            event = self.__recievejsonresponse__()
            print(event)
            self.prevEvent = event            
            try:
                #print(f"{author}:{content}")
                op_code = event["op"]
                if op_code == 11:
                    print("heartbeat recievedd")
            except:
                pass

    def heartbeat(self):
        print("heartbeating")
        heartbeatJSON = {
                "op": 1,
                "d": "null"
            }
        self.__sendjsonrequest__(heartbeatJSON)
        while True:
            time.sleep(self.heartbeat_interval)
            heartbeatJSON = {
                "op": 1,
                "d": "null"
            }
            self.__sendjsonrequest__(heartbeatJSON)

    def __recievejsonresponse__(self):
        response = self.ws.recv()
        if response:
            return json.loads(response)
        
    def __sendjsonrequest__(self, request):
        self.ws.send(json.dumps(request))

在运行这段代码时，我得到了以下错误

{'t': None, 's': None, 'op': 11, 'd': None}
