【问题描述】：

@client.command()
async def csgonow(ctx):
    url = "https://steamdb.info/app/730/graphs/" 
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            soupObject = BeautifulSoup(await response.text(), "html.parser")
            online = soupObject.find(class_='home-stats').find('li').find('strong').get_text()
            await ctx.send(online + ' players are playing this game at the moment')

当我使用命令!R csgonow 时出现此错误：

 discord.ext.commands.errors.CommandInvokeError: Command raised an exception:
  AttributeError: 'NoneType' object has no attribute 'find'

我该如何解决这个问题？

【问题讨论】：

对我来说看起来不错，但如果您添加一些调试消息以查看发生了什么会更容易。例如。将await response.text() 保存在变量中并打印出来。它还有助于删除不必要的代码。例如。不和谐，因为您的问题似乎与不和谐无关。

【参考方案1】：

您可以使用 CSS 选择器：

@client.command()
async def csgonow(ctx):
    url = "https://steamdb.info/app/730/graphs/"
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            soupObject = BeautifulSoup(await response.text(), "html.parser")
            online = soupObject.select_one('.app-chart-numbers-big > li:nth-child(2) > strong:nth-child(1)').text
            await ctx.send(f' online players are playing this game at the moment')
