Aiogram框架报错：'State'类型对象无'Form'属性的技术问询

错误原因 #

你误用了State类来创建表单状态结构。在Aiogram框架中，用于定义多状态表单的是StateGroup类，State.Form并非框架提供的属性，这是导致报错的直接原因。此外你重复初始化了Bot和Dispatcher实例，这会引发后续的异步会话未关闭警告。

修复步骤 #

1. 修正导入语句
   补充导入StateGroup类，替换原有的单一State导入：

   from aiogram.dispatcher.filters.state import State, StateGroup
   

2. 重构Form类定义
   让Form继承StateGroup，而非不存在的State.Form：

   # States
   class Form(StateGroup):
       id = State()
       text = State()
   

3. 移除重复的Bot/Dispatcher初始化
   删除代码中重复的这两行，避免创建多个实例导致资源泄漏：

   bot = Bot(token=API_TOKEN)
   dp = Dispatcher(bot, storage=storage)
   

完整修正后的代码片段 #

import logging

import aiogram.utils.markdown as md
from aiogram import Bot, Dispatcher, types
from aiogram.contrib.fsm_storage.memory import MemoryStorage
from aiogram.dispatcher import FSMContext
from aiogram.dispatcher.filters import Text
from aiogram.types import ParseMode
from aiogram.utils import executor
from aiogram.dispatcher.filters.state import State, StateGroup  # 修正导入

API_TOKEN = '5813603682:AAHxbhe4tMIC3GxxO1Pi26PGn-ovtxW8k9M'

storage = MemoryStorage()
bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot, storage=storage)
logging.basicConfig(level=logging.INFO)
# 移除重复的bot和dp初始化代码

# States
class Form(StateGroup):  # 继承StateGroup
    id = State()
    text = State()

# 后续消息处理代码...
