机器人不断执行循环的随机部分

Question

我试图使一个机器人，每当它检测到页面状态变化时发送消息，但3-5秒后，它随机发送“服务器在线”，即使页面没有任何变化。

import os
import discord
from dotenv import load_dotenv
import time
import requests

def check(r):
    if "online" in r.text:
        return True
    else:
        return False

online = False

load_dotenv()
TOKEN = "#hidden"
GUILD = #hidden

client = discord.Client()

@client.event 
async def on_ready():
    for guild in client.guilds:
        if guild.name == GUILD:
            break
    print(
        f'{client.user} is connected to the following guild:\n'
        f'{guild.name}(id: {guild.id})')
    channel = client.get_channel(#hidden)

    last_status = check(requests.get("#page"))
    while True:
        if check(requests.get("#page")) == last_status:
            continue
        else:
            if check(requests.get(#page")):
                await channel.send("server is online")
                last_status = check(requests.get("#page"))
            else:
                await channel.send("Server is offline")
                last_status = check(requests.get("#page"))


client.run(TOKEN)

Answer 1

这可能是因为您有多个正在运行的on_ready函数实例。

不一致API通常会发送重新连接的指令(特别是在由于流行病而导致负载过载的这段时间内)。

当discord.py收到此指令时，它会重新连接并再次调用on_ready，而不会终止另一个。

解决方案是使用asyncio.ensure_future和client.wait_until_ready来确保只有一个实例

代码：

import os
import discord
from dotenv import load_dotenv
import time
import requests
import asyncio

def check(r):
    if "online" in r.text:
        return True
    else:
        return False

online = False

load_dotenv()
TOKEN = "#hidden"
GUILD = #hidden

client = discord.Client()

async def routine():
    await client.wait_until_ready()

    channel = client.get_channel(#hidden)    
    last_status = check(requests.get("#page"))

    while True:
        if check(requests.get("#page")) == last_status:
            continue
        else:
            if check(requests.get(#page")):
                await channel.send("server is online")
                last_status = check(requests.get("#page"))
            else:
                await channel.send("Server is offline")
                last_status = check(requests.get("#page"))


@client.event 
async def on_ready():
    for guild in client.guilds:
        if guild.name == GUILD:
            break
    print(
        f'{client.user} is connected to the following guild:\n'
        f'{guild.name}(id: {guild.id})')

asyncio.ensure_future(routine())
client.run(TOKEN)
