discord.py中链式调用多个Discord模态框的实现问题

核心错误点 #

• 异步函数拼写错误：两处asnyc都要改成async
• 提交方法名拼写错误：两处on_sumbit都要改成on_submit
• 命令函数定义缺冒号：async def main(self,interaction:discord.Interaction)末尾必须加:

这些语法错误会导致Discord无法正确识别模态框的提交处理逻辑，交互得不到正确响应，就会弹出"Something went wrong, try again"的提示，同时无法触发下一个模态框。

修复后的完整代码 #

class Modal_2(discord.ui.Modal, title="Modal_2"):
    question_1 = discord.ui.TextInput(label="That's the second question")

    async def on_submit(self, interaction: discord.Interaction):
        await interaction.response.send_message(content="Thanks for your input")

class Modal_1(discord.ui.Modal, title="Modal_1"):
    question_1 = discord.ui.TextInput(label="That's the first question")

    async def on_submit(self, interaction: discord.Interaction):
         await interaction.response.send_modal(Modal_2())

class main(commands.Cog):
    def __init__(self, bot):
          self.bot = bot

    @app_commands.command(name="survey")
    async def main(self, interaction: discord.Interaction):
         await interaction.response.send_modal(Modal_1())

额外注意事项 #

• 确保使用的discord.py版本在v2.0及以上，旧版本对模态框链式调用的支持不完善
• 修复后提交第一个模态框时，Discord会自动关闭当前模态框并弹出第二个，完成流程后会发送感谢消息
