NameError:未定义名称'ask‘

Question

烧瓶的问题

@ask.launch问题

我在运行python flask脚本时遇到问题。我使用的是Python2.7，错误显示:文件"C:\Users\user1\AppData\Local\Continuum\anaconda2\Lib\site-packages\hello_lumion.py"，第13行，在@ask.launch NameError中:未定义名称'ask‘

import logging
import os 


from flask import request
from flask import Flask

from flask_ask import Ask, statement, request, context, session, question,  version

import requests


@ask.launch
def welcome():
    return statement ('Welcome to Foo')


app = Flask(__name__)

ask= Ask(app,"/")

logging.getLogger("flask_ask").setLevel(logging.DEBUG)

@ask.intent("Hello")

def hello():
    msg= "hello from lumion"
    return statement (msg)


if __name__ == '__main__':
    port = 9000
    app.run(host='0.0.0.0', port=port)
    app.run(debug=True) 

对于如何克服这个问题，有什么建议吗？

Answer 1

在定义ask之前，您正在调用它。在你的代码中，你有

@ask.launch # ask has not been made
def welcome():
    return statement ('Welcome to Foo')


app = Flask(__name__)

ask= Ask(app,"/") # ask gets made here!

您将需要对其重新排序，以便当您调用ask时，它已被定义。类似于：

app = Flask(__name__)

ask= Ask(app,"/") # define it first

@ask.launch # now use it
def welcome():
    return statement ('Welcome to Foo')
