Discord机器人interactions.py开发/rpc命令时出现应用未响应错误

问题根源 #

1. 类型不匹配：player参数通过选项返回的是字符串类型（"0"/"1"/"2"），但代码中直接与整数类型的bot做条件判断，导致所有分支都无法触发，没有执行ctx.send返回响应，Discord因此提示应用未响应。
2. 索引错误：options[player]会抛出异常——字符串不能作为列表索引，这会直接终止命令执行，同样不会返回任何响应。

修复后的代码 #

@slash_command(name="rpc", description="Rock Paper Scissors")
@slash_option(
    name="player",
    description="Your Choice",
    required=True,
    opt_type=OptionType.STRING,
    choices=[
        SlashCommandChoice(name="Rock", value="0"),
        SlashCommandChoice(name="Paper", value="1"),
        SlashCommandChoice(name="Scissors", value="2")
    ]
)
async def rpc_function(ctx: SlashContext, player: str):
    try:
        # 将字符串类型的player转为整数
        player = int(player)
        bot = random.randint(0,2)
        options = ["Rock", "Paper", "Scissors"]
        
        if player == bot:
            # TIE
            await ctx.send(f"We both choose **{options[bot]}**, Tied")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 0 and bot == 1:
            # BOT WON / ROCK - PAPER
            await ctx.send(f"I choose **{options[bot]}** so I WON")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 0 and bot == 2:
            # PLAYER WON / ROCK - SCISSORS
            await ctx.send(f"You won cuz I choose **{options[bot]}**")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 1 and bot == 0:
            # PLAYER WON / PAPER - ROCK
            await ctx.send(f"YOU WON, I choose **{options[bot]}**")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 1 and bot == 2:
            # BOT WON / PAPER - SCISSORS
            await ctx.send(f"HEHE I WON CUZ I CHOOSE **{options[bot]}**")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 2 and bot == 0:
            # BOT WON / SCISSORS - ROCK
            await ctx.send(f"I won, I choose {options[bot]}")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
        elif player == 2 and bot == 1:
            # PLAYER WON / SCISSORS - PAPER
            await ctx.send(f"You won cuz I choose {options[bot]}")
            print(f"{datetime.datetime.now().strftime('%x %X')} {ctx.author.username} Used /rpc player={options[player]} bot={options[bot]}")
    except Exception as e:
        # 捕获异常并返回错误信息，避免无响应
        await ctx.send(f"An error occurred: {str(e)}")
        print(f"Error in /rpc command: {str(e)}")

关键修复点 #

• 新增player = int(player)，将字符串参数转为整数，解决类型不匹配问题。
• 加入try-except块捕获异常，确保即使出现错误也会给用户返回响应，避免Discord提示应用未响应。
• 优化print语句的格式化，让日志输出更整洁。
