有限状态机。过滤器必须是可调用和/或可等待的！

  • 772

我用的是 FSM，aiogram 2*。我收到以下错误： TypeError：过滤器必须可调用和/或可等待！

一切似乎都是按照FSM的指示进行的。我知道这是一个类型错误。但也许在版本 2 aiogram 中写法有所不同？我在文档中找不到它。先感谢您！

class UserStates(StatesGroup):
    find_group = State()

@dp.message_handler(text=['Найти группу'])
async def func(message: types.Message, state: FSMContext):
    keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
    await message.answer("Введите номер группы", reply_markup=keyboard)
    state.set_state(UserStates.find_group)

@dp.message_handler(UserStates.find_group)
async def func(message: types.Message, state: FSMContext):
    if(message.text == '7'):
        await bot.send_message(message.chat.id, "Вы ввели номер группы 7")
    elif(message.text == '6'):
        await bot.send_message(message.chat.id, "Вы ввели номер группы 6")
    else:
        await bot.send_message(message.chat.id, "Такой группы не существует")
    state.clear()

错误：

    从您提供的链接来看，这一行写得不正确：

    state.set_state(UserStates.find_group)

    它应该看起来像这样（修正了两个地方）：

    await state.set_state(UserStates.find_group.state)
^^^^^^                                     ^^^^^^

    显然，状态设置不正确，因此消息处理程序在访问此状态时会抱怨。

    好吧，此外，正如我在评论中所写的那样，您具有相同的函数名称func，第二个与第一个重叠。这就是为什么最好使用“会说话”的函数名称，因为它们重合的可能性较小。在这种情况下，这些可以是以下函数名称：（input_group输入组名称）和find_group（按名称搜索组本身）。
