Discord.py反垃圾邮件忽略通道命令中断

Question

你好，我正在尝试做一个反垃圾邮件机器人，以工作捕捉垃圾邮件发送者和踢出服务器。但我的问题是，代码忽略了行会中的所有通道，而不是json文件中的通道。这是我的代码，请您看一看，并更新我做错了什么。谢谢

@client.listen()
async def on_message(message):
    counter = 0
    with open("spam-bank.txt", "r+") as file:
        for lines in file:
            if lines.strip("\n") == str(message.author.id):
                counter += 1
        file.writelines(f"{str(message.author.id)}\n")
        try:
          with open("channels.json", "r") as r:
            j = json.load(r)
            all_channels = j["channels"]
            return all_channels
          if counter > 3:
            await message.channel.send(f'{message.author} has been kicked for spamming')
            await message.guild.kick(message.author,reason="Caught by Anti-Spam for Spamming")
            print(f'{message.author} was kicked')
            await asyncio.sleep(2)
        except:
            return

@client.command()
async def ignore(ctx, channel_):
    def add_channel(channel, file="channels.json"):
        with open(file, "r+") as fw:
            j = json.load(fw)
            j["channels"].append(channel)
            with open(file, "w+") as wp:
                wp.write(json.dumps(j))

    try:
        with open("channels.json", "r"):
            pass
    except:
        with open("channels.json", "w+") as wp:
            wp.write('{"channels" : []}')
    finally:
        add_channel(channel_)
        await ctx.send("Done!")

问题是：

with open("channels.json", "r") as r:
    j = json.load(r)
    all_channels = j["channels"]
    return all_channels

当执行命中return all_channels时，函数结束，并返回all_channels。在此之后将不会有任何代码。

相反，您需要编写代码来检查消息被发送到的通道是否包含在all_channels中，并且只在这种情况下返回/跳过。

将来解决这个问题的一个简单方法是添加许多临时的print语句，并通过跟随print语句来跟踪这个函数。

with open("channels.json", "r") as r:
    j = json.load(r)
    print("loaded json from file")
    all_channels = j["channels"]
    print(f"extracted channels from json: {all_channels}")
    return all_channels
print(f"checking counter: {counter}")
if counter > 3:
   print("user has sent more than 3 messages. Kicking..")
   await message.channel.send(f'{message.author} has been kicked for spamming')
   await message.guild.kick(message.author,reason="Caught by Anti-Spam for Spamming")
   print(f'{message.author} was kicked')
   await asyncio.sleep(2)

你会得到像这样的输出

loaded json from file
extracted channels from json: [list]

从这一点，您可以很容易地看出，在打印语句和下一个语句之间出现了问题，因为checking counter: [number]没有被打印出来。
