问题背景 #

已知报错源于名称不符合^[\w-]{1,32}$正则规则，但对正则不熟悉。相关代码如下：

# modlink (link/unlink/purgeall)
@client.slash_command(guild_ids=serverids,description="Link/Unlink mods ids from the reports section. (Manager Only)")
async def mod(interaction: Interaction):
    pass
@mod.subcommand(description="Links/Adds their mod in-game id's to their discord UserID. (Manager Only)")
async def add(interaction: Interaction, target: nextcord.User, ingameID: str):
    if check_manager(interaction.user.id) == True:
        print("test")
    else:
        await interaction.response.send_message(f"{interaction.user.mention}",embed=prefabembeds.NoManagerPerms)
        print(f"~$- log: (failed) modlink add (target: [{target}, {target.id}], ingameID: {ingameID}), user: [{interaction.user.id}, {interaction.user}]")

已尝试修改装饰器参数和函数名重命名命令，问题仍未解决。

问题分析与解决方案 #

正则规则通俗解释 #

^[\w-]{1,32}$ 实际要求：

• 只能用小写英文字母、数字、下划线、连字符
• 长度在1-32字符之间
• 不能含空格、大写字母、特殊符号（如中文、引号等）

错误定位 #

报错里的options.0.options.1.name指向的是命令参数名称，而非命令本身。你的代码中参数ingameID包含大写字母（I、D），违反了Discord应用命令的参数命名规则。

修改方案 #

将参数名改为全小写格式，比如ingame_id或ingameid，修改后的代码示例：

# modlink (link/unlink/purgeall)
@client.slash_command(guild_ids=serverids,description="Link/Unlink mods ids from the reports section. (Manager Only)")
async def mod(interaction: Interaction):
    pass
@mod.subcommand(description="Links/Adds their mod in-game id's to their discord UserID. (Manager Only)")
async def add(interaction: Interaction, target: nextcord.User, ingame_id: str):
    if check_manager(interaction.user.id) == True:
        print("test")
    else:
        await interaction.response.send_message(f"{interaction.user.mention}",embed=prefabembeds.NoManagerPerms)
        print(f"~$- log: (failed) modlink add (target: [{target}, {target.id}], ingameID: {ingame_id}), user: [{interaction.user.id}, {interaction.user}]")

额外提醒 #

• 所有命令参数的名称都需符合上述规则，包括子命令参数
• 命令名称（主命令、子命令）同样要遵守规则，但你的代码中mod和add是合规的
