Discord.py: 在检查中使用特殊响应导致不同的输出
Discord.py: Use special responses in checks to cause different output
所以，这似乎是一个奇怪的问题，但我最近为我的 discord 机器人创建了一个命令，让用户逐步创建嵌入。它工作得很好，但我想实现一种方法来完成命令，即使没有填写所有字段。因此，如果用户在构建嵌入时键入“完成”，它将把他们带到构建过程的一部分，询问他们要将嵌入发送到什么渠道。这是我的代码：
@embed.command()
@commands.has_permissions(manage_permissions = True)
@commands.bot_has_permissions(manage_permissions = True)
async def build(self, ctx):
channel = ctx.channel
content = f''
def check(m):
if m.channel == m.channel and m.content == "CANCEL":
raise ValueError("Cancelled command")
return m.content.lower is not None and m.channel == channel and m.content.lower
# The first round: TITLE

await firstin.delete() # Delete the first input
await beggining.delete()
firstembed=discord.Embed(title=f'{firstin.content}')
# The second round: MAIN BODY

await secondin.delete() # Delete the second input
secondembed=discord.Embed(title=firstin.content, description=secondin.content)

# The ninth round: CHANNELS

@build.error
async def build_error(self, ctx, error):
if isinstance(error, commands.errors.CommandInvokeError):
await ctx.send(f'{x_mark} The embed has been terminated, you will have to start over. This was either due to cancellation or an incorrect argument.')
有什么办法可以做到这一点吗？谢谢
您可以自己创建自定义错误，每次命令本身出现故障时都会调用 CommandInvokeError，这不是最佳选择 imo，方法如下：
class CancelledCommand(commands.CheckFailure):
pass
# Somewhere (in the check func)
raise CancelledCommand('Command has been cancelled')
# In the error handler
if isinstance(error, CancelledCommand):
...
此外，关于检查功能的 4 件事
str.lower()是方法，不是属性，需要调用。m.content 永远不会是 None.m.channel == m.channel 根本没有任何意义，我想你的意思是 m.channel == ctx.channel- 您可能应该检查
m.author == ctx.author
检查改进如下：
def check(m):
if m.channel == ctx.channel and m.author == ctx.author:
if m.content.lower() == 'finish':
raise CancelledCommand('Command has been cancelled')
return True
return False
