Discord机器人报错：'Client'对象无'author'属性求助

问题描述 #

开发亚马逊网页爬取Discord机器人时出现错误：AttributeError: 'Client' object has no attribute 'author'，报错提示位于文件/Users/kailash/Documents/devkai/Amazon Scrapper/bot.py的on_message函数第13行，但该行实际为空。尝试更换discord.py版本为1.0.1，问题仍未解决。

代码示例 #

import discord
from amazon import search

TOKEN = 'hidden'
CHANNEL_ID = 'hidden'

client = discord.Client()

@client.event
async def on_message(message):
    if message.author == client.user:   #line 11
        return 
#line 13
    if message.channel.id != CHANNEL_ID:
        return

    if message.content.split(' ')[0] == '!amazon':
        try:
            query = message.content.replace('!amazon ', '')

            item = search(query)

            embed = discord.Embed(
                title=item['title'],
                url='https://www.amazon.co.uk/' + item['url']
            )
            embed.set_thumbnail(
                url=item['img']
            )
            embed.add_field(
                name='Price',
                value=item['price']
            )
            embed.add_field(
                name='Rating',
                value=item['rating']
            )
            embed.add_field(
                name='Number of Ratings',
                value=item['number_of_ratings']
            )
            await message.channel.send(embed=embed)
        except:
            response = 'An error occurred with your request.'
            await message.channel.send(response)

client.run(TOKEN)

终端报错信息 #

解决方案 #

1. 核对代码行号与实际内容：报错提示的第13行可能因空行、注释的行号统计偏差，实际错误大概率是误将message写成client（比如client.author），需检查on_message函数内所有涉及author的代码，确保调用的是message.author而非client.author。
2. 修正频道ID类型：message.channel.id是整数类型，当前CHANNEL_ID定义为字符串，需将其转换为整数，避免类型不匹配引发的逻辑异常：

   CHANNEL_ID = int('你的频道ID')
   

3. 调整discord.py版本：1.0.1版本较老旧，可尝试升级到v1.7.3（该版本与你的代码结构兼容，且是v1.x分支的稳定版），执行命令：

   pip install discord.py==1.7.3
   

4. 排查外部函数问题：若上述操作无效，需检查amazon.py中的search函数，确认是否在内部错误调用了client.author导致报错。
