在函数中执行await的时候报出以上错误，从字面意思翻译是await不在async 函数当中，是因为我创建的函数前面没有添加async关键字

def result_page(request: Request, username: str = Form(...), password: str = Form(...)):
    """
    返回用户注册信息
    :param request:
    :param username:
    :param password:
    :return:
    """
    add_user = await User().create(username=username, password=password)
    # user_infos = await User().all()
    # add_user = await User().create(username=username, password=password)
    print("user_info", add_user)
    print(username, password)
    return request.app.state.views.TemplateResponse("reg_result.html",
                                                    {"request": request,
                                                     "username": username,
                                                     "password": password})

# 在以上函数前面加上async，报错就解除了

async def result_page(request: Request, username: str = Form(...), password: str = Form(...)):
    """
    返回用户注册信息
    :param request:
    :param username:
    :param password:
    :return:
    """
    add_user = await User().create(username=username, password=password)
    # user_infos = await User().all()
    # add_user = await User().create(username=username, password=password)
    print("user_info", add_user)
    print(username, password)
    return request.app.state.views.TemplateResponse("reg_result.html",
                                                    {"request": request,
                                                     "username": username,
                                                     "password": password})

还有另外一个原因是因为 await是要和创建协程时async一起搭配使用的，直接使用await就会找不到他所在的函数的，于是报错在函数外。使用asyncio创建任务队列，进行调用

import asyncio

async def func1():
    await asyncio.sleep(10)
    print('等待10秒')

async def func2():

    await asyncio.sleep(20)
    print('等待20秒')

task_list=[func1(),func2()]
loops=asyncio.get_event_loop()
loops.run_until_complete(asyncio.wait(task_list))
