Using the following code, I've setup a flask app:
https://gist.github.com/ugik/a218a599b1af0ea06b1b38e3a5132078#file-flaskfbmapi-ai-rig
import requests

# api.ai credentials
CLIENT_ACCESS_TOKEN = "78c0e0...d9404a2"
ai = apiai.ApiAI(CLIENT_ACCESS_TOKEN)
app = Flask(__name__)
#app.route('/', methods=['GET'])
def verify():
# our endpoint echos back the 'hub.challenge' value specified when we setup the webhook
if request.args.get("hub.mode") == "subscribe" and request.args.get("hub.challenge"):
if not request.args.get("hub.verify_token") == 'foo':
return "Verification token mismatch", 403
return request.args["hub.challenge"], 200
return 'Hello World (from Flask!)', 200
def reply(user_id, msg):
data = {
"recipient": {"id": user_id},
"message": {"text": msg}
}
resp = requests.post("https://graph.facebook.com/v2.6/me/messages?access_token=" + ACCESS_TOKEN, json=data)
print(resp.content)
#app.route('/', methods=['POST'])
def handle_incoming_messages():
data = request.json
sender = data['entry'][0]['messaging'][0]['sender']['id']
message = data['entry'][0]['messaging'][0]['message']['text']
# prepare API.ai request
req = ai.text_request()
req.lang = 'en' # optional, default value equal 'en'
req.query = message
# get response from API.ai
api_response = req.getresponse()
responsestr = api_response.read().decode('utf-8')
response_obj = json.loads(responsestr)
if 'result' in response_obj:
response = response_obj["result"]["fulfillment"]["speech"]
reply(sender, response)
return "ok"
if __name__ == '__main__':
app.run(debug=True)
However, at line 51 there is an error in my server logs:
UnboundLocalError: local variable 'response' referenced before
assignment
Which I understand the root of the cause is "response" is defined only within the if statement, however, since it is not my code, I'm having trouble defining the variable outside. Will this work if I place this code after line 48:
response = response_obj["result"]["fulfillment"]["speech"]

I have trained a model, and now wish to print the data on user's demand.
I am seeing this error in server.py file, " The browser (or proxy) sent a request that this server could not understand." I checked everything works fine if I am sending data to browser but not when asking for the data, I tried Postman for sending the data.
http://127.0.0.1:5000/predict_home_price -> shows bad request.
http://127.0.0.1:5000/locations -> shows correct data
http://127.0.0.1:5000/hi -> shows correct data
As you mentioned, when you're sending data to the server it works, and that's because you're using a POST request and the request has form data in it.
But when you're "asking for data", you're probably using a GET request, which has no form data in it, and that's why the server responses with an error.
You can modify your code so you can decide what you should do for each type of request:
#app.route('/predict_home_price', methods=['GET', 'POST'])
def predict_home_price():
if request.method == "POST":
# get form data and do something with it
elif request.method == "GET":
# return some value, without looking for form data
length of the password must be at least 6 characters while signing up using Dialogflow chatbot.
I have used system entity "any". But it is so generalized.
Webhook is written in flask python.
Also tried to do it by using [0-9]{6}$ as a regex entity. But unable to find a proper way to perform this task.

agent.add('I am the chatbot of this page. Ready to assist you with anything you need. What would you like to do?')
agent.add(QuickReplies(quick_replies=['START NOW','LOGIN']))
if intent_name == 'get_started':
url = 'http://**********.com/create_account'
userid = req.get('queryResult').get('parameters').get('email')
print(userid)
pwd = req.get('queryResult').get('parameters').get('pwd')

How to do this properly?
How to use regex in it?
Or should i use another approach?
I am using python and I apologize as this is probably a very simple concept that I am not grasping but I am not very familiar with the flask framework. Right now I'm making a server with flask but run into a 405 error every time I try to do something with the twitter api shortly after. Right now my code looks something like this
In a separate file:
from flask import Flask
from threading import Thread
app = Flask('')
#app.route('/', methods=['GET', 'POST', 'DELETE'])

The error returned states the following:
"Error response
Error code: 405
Message: Method Not Allowed.
Error code explanation: 405 - Specified method is invalid for this resource."
Basically I call the flask file then use twitter api to upload a file, but for some reason using the twitter api always results in a 405 error and my flask server is no longer accessible. How can I adjust my flask file to allow me to upload using the api?
405 errors are thrown when the wrong request method is used. For example a POST request being sent when a GET request was expected, or a GET request being sent when a POST request was expected.
In your check_status function you have
req = requests.get(url=MEDIA_ENDPOINT_URL, ...
But according to Twitter's documentation you should be using a post request here
req = requests.post(url=MEDIA_ENDPOINT_URL, ...
I created a webhook using python ( using this example) for my project in api.ai
My code is here :
#!/usr/bin/env python
import urllib
import json
import os
from flask import Flask
from flask import request
from flask import make_response
# Flask app should start in global layout
app = Flask(__name__)
#app.route('/webhook', methods=['POST'])
def webhook():
req = request.get_json(silent=True, force=True)
print("Request:")
print(json.dumps(req, indent=4))
res = makeWebhookResult(req)
res = json.dumps(res, indent=4)
print(res)
r = make_response(res)
r.headers['Content-Type'] = 'application/json'
return r
def makeWebhookResult(req):
if req.get("result").get("action") != "delivery.info":
return {}
result = req.get("result")
parameters = result.get("parameters")
parcelnr = parameters.get("parcelnumber")
parcelinfo = {'5000':'your parcel has been shipped', '5001':'your parcel has
not been shipped', '5002':'should be delivered on three days', '5003':'your
parcel has not been shipped', '5004':'your parcel has been shipped'}
speech = "Parcel with numner" + parcelnr + " is " +
str(parcelinfo[parcelnr]) "
print("Response:")
print(speech)
return {
"speech": speech,
"displayText": speech,

}
if __name__ == '__main__':
port = int(os.getenv('PORT', 5000))
print "Starting app on port %d" % port
app.run(debug=True, port=port, host='0.0.0.0')
Api agent is :
image1
image2
I don't understand where i'm wrong.
My agent work ok, but when i ask the bot to get info from the webhook i get the text response from api.ai not from webhook.
Can you help me please ?
The following is working for me. request.data will be receiving message alerts from the TradingView webhook message.
#app.route('/webhook', methods=['POST'])
def webhook():
print("\nrequest.data={}".format(request.data))
return request.data
In TradingView Alert Message, I am using following...
exchange = {{exchange}}, ticker = {{ticker}}, price = {{close}}, volume = {{volume}}
...and I am getting following message in logs:
$ heroku logs --tail
2022-01-12T20:38:00.510006+00:00 app[web.1]: request.data=b'exchange = BINANCE, ticker = BTCUSDT, price = 43671.85, volume = 10.70612'

You are using the wrong url for the webhook in the fulfillment.
Your code is mapping the request to /webhook, while your url is https://your-domain.com/debotwebhook.
Either change #app.route('/webhook', methods=['POST']) to #app.route('/debotwebhook', methods=['POST']) or change the url in api.ai to https://your-domain.com/webhook
Also, I see an extra " in your speech variable after str(parcelinfo[parcelnr]).
Here is the agent I tested with your code and on the right you can see the answer:

I can think of two possible problems.
JWT token needs to be base64 encoded
You may have forgotten : at the end
e.g. If your token is as follows (Taken from jwt.io site)
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ
You need to do the following:
$ echo 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ:' | base64
