Question

我尝试了这些代码

def get_prefix(client, message):
with open('prefixes.json', 'r') as f:
    prefixes = json.load(float)

    return prefixes[str(message.guild.id)]

client = commands.Bot(command_prefix = get_prefix)

@client.event
async def on_guild_join(guild):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(float)

    prefixes[str(guild.id)] = ','

    with open('prefixes.json', 'w') as f:
        json.dump(prefixes, float, indent=4)

@client.event
async def on_guild_remove(guild):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes.pop(str(guild.id))

    with open('prefixes.json', 'w') as float:
        json.dump(prefixes, float, indent=4)

@client.command()
@commands.has_permissions(manage_channels=True)
async def prefix(ctx, prefix):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes[str(ctx.guild.id)] = prefix

    with open('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent=4)

    await ctx.send(f'Prefix changed succesfully, now my prefix for this server is: "{prefix}"')

我得到了这些错误

忽略on_message中的异常追溯（最近一次通话）： _run_event中的文件“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ client.py”，第312行等待科罗（* args，** kwargs）文件“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ ext \ commands \ bot.py”，行943，在on_message中等待self.process_commands（消息）文件“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ ext \ commands \ bot.py”，行939，在process_commands中 ctx =等待self.get_context（消息） get_context中的第853行“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ ext \ commands \ bot.py” 前缀=等待self.get_prefix（消息） get_prefix中的第798行的文件“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ ext \ commands \ bot.py” ret =等待discord.utils.maybe_coroutine（前缀，自身，消息）文件“ C：\ Users \ PC \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ site-packages \ discord \ utils.py”，行> 331，在may_coroutine中值= f（* args，** kwargs） get_prefix中的第20行的文件“ C：\ Users \ PC \ Desktop \ Code \ Project 01 \ index.py” 返回前缀[str（message.guild.id）] KeyError：'744103149471662152'

请帮助，它已经在几周前工作了。

Answer 1

服务器ID不在JSON文件中

手动添加它，或者从该服务器中踢出机器人并再次重新邀请它

Answer 2

好的。首先，您正在运行json.loads(float)。浮动是一种功能，而不是文件。我编辑了您发布的代码，请尝试使用此代码：

def get_prefix(client, message):
with open('prefixes.json', 'r') as f:
    prefixes = json.load(f)

    return prefixes[str(message.guild.id)]

client = commands.Bot(command_prefix = get_prefix)

@client.event
async def on_guild_join(guild):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes[str(guild.id)] = ','

    with open('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent=4)

@client.event
async def on_guild_remove(guild):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes.pop(str(guild.id))

    with open('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent=4)

@client.command()
@commands.has_permissions(manage_channels=True)
async def prefix(ctx, prefix):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes[str(ctx.guild.id)] = prefix

    with open('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent=4)

    await ctx.send(f'Prefix changed successfully, now my prefix for this server is: "{prefix}"')

（我还修复了您邮件中的一些拼写错误）

如果那仍然给您带来错误，请启动bot并重新邀请。那应该可以。

Answer 3

def get_prefix(client, message):
    with open('./database/prefixes.json', 'r') as f:
        prefixes = json.load(f)
    return prefixes[str(message.guild.id)]

你正确加载了 float 而不是写 f 并检查json文件中的服务器ID 尝试手动编辑或踢机器人并再次邀请它
