使用 Python 和 Pycord 在循环中触发方法

Question

我正在玩 Pycord 并尝试为数组中的每个元素向通道 X 发送消息。

下面的class会抛出一个TypeError: MyClient.on_ready() missing 1 required positional argument: 'message'表示MyClient.on_ready()需要2个参数，一个给self，一个给message，但是每个例子关于如何将参数传递给 class 方法只是发送参数。

class MyClient(discord.Client):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
    
    async def on_ready(self, message):
        channel = self.get_channel(123)  # Your channel ID goes here
        await channel.send(message)

client = MyClient()

for comment in comments:   
    if  comment['data']['parent_id'].startswith("t1") and comment['data']['name'] not in comments_json:
        wop = comment['data']['permalink']
        client.on_ready(wop)
        client.run("xxx")

我错过了什么？

编辑：添加了评论中的更改，现在错误消息如下：

coroutine 'MyClient.on_ready' was never awaited
  client.on_ready(wop)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
Ignoring exception in on_ready
Traceback (most recent call last):
  File "C:\Python310\lib\site-packages\discord\client.py", line 352, in _run_event
    await coro(*args, **kwargs)
TypeError: MyClient.on_ready() missing 1 required positional argument: 'message'

Answer 1

你得到的错误是因为 on_ready 没有接受任何参数

也许您正在寻找这样的东西，获取一个通道对象并发送一个数组（也像您发送的代码一样进行子类化）

import discord
import os
import asyncio
from typing import Iterable, Optional, Any


class MyClient(discord.Client):

    # > trying to send a message to a channel X for each element in an array.
    def __init__(
        self,
        channel_to_send: int,
        array: Iterable,
        *,
        loop: Optional[asyncio.AbstractEventLoop] = None,
        **options: Any
    ):
        self.channel_to_send = channel_to_send
        self.array = array
        super().__init__(loop=loop, **options)

    async def on_ready(self):
        channel_ = await self.fetch_channel(self.channel_to_send)
        for element in self.array:
            await channel_.send(element)


channel_id = 917803321929134133 # Replace this with that of yours 
array = ["foo", "bar", "this", "is", "working"] # Replace this with that of yours

client = MyClient(channel_id, array)
client.run(os.getenv("DISCORD_TOKEN"))

结果：

使用 Python 和 Pycord 在循环中触发方法

Triggering method from within a loop with Python and Pycord

python

discord.py
