如何在所有频道发送消息

Question

我想向bot已加入的所有频道发送消息

def check(cnt): 
    while 1:  
        if hash_origin != str(subprocess.check_output(["md5sum",filename])[:-len(filename)-3])[2:-1] :
            print("file destroyed alert!")
            alert = 1
        sleep(0.5)

当特定文件的散列结果与原始结果不同时，我希望将消息发送到bot加入的所有不协调通道。我知道如何向频道发送回复信息

@client.event
async def on_message(message):

用这个代码，对吗？但我想发送消息到所有的通道，机器人已加入当一些事件发生。

Answer 1

@client.event
async def foo(bar): # change this to the event in which you wish to call it from
    for guild in client.guilds:
        for channel in guild.channels:
            await channel.send(messagedata) # change messagedata to whatever it is you want to send.

直接使用此代码时，出现错误

AttributeError: 'CategoryChannel' object has no attribute 'send'  

因为guild.channels对象列表的所有渠道（包括文本，语音等），机器人已加入。

Answer 2

为了向机器人所在的每个通道发送消息，您必须执行以下操作：

@client.event
async def foo(bar): # change this to the event in which you wish to call it from
    for guild in client.guilds:
        for channel in guild.channels:
            await channel.send(messagedata) # change messagedata to whatever it is you want to send.
