Code for my Tutorial on building a Facebook Messenger bot using Django/Python

Facebook Messenger Bot tutorial using Django/Python

This has the starter code for the tutorial I wrote on my Blog.

Tutorial: How to build a Facebook Messenger bot using Django, Ngrok

How to use

Run the following commands. You will need Python 2.7+/3.3+ and have Virtual Environment Wrapper setup.

git clone https://github.com/abhay1/django-facebook-messenger-bot-tutorial.git
cd django-facebook-messenger-bot-tutorial
mkvirtualenv bottutorial
pip install -r requirements.txt
cd yomamabot
python manage.py runserver

Follow the tutorial to setup Ngrok. Edit the VERIFY_TOKEN variable in django-facebook-messenger-bot-tutorial/yomamabot/fb_yomamabot/views.py to include the Verify token. It is set to 2318934571 as default that is used in the tutorial. This can be any token as long as it matches the one you tell Facebook.

Once you have your webhook setup, get your Page Access Token. Then set the PAGE_ACCESS_TOKEN variable in the file django-facebook-messenger-bot-tutorial/yomamabot/fb_yomamabot/views.py to your page access token.

Still Works this method

I'm trying to integrate facebook messenger in my website, but I'm curious that still this method works or not

Is it working with comments ?

How to make this project work with comments and if i want to save all news even to db how i can do that's ?

Thanks so much Abhay !

Can't get user name

Hi!
When I run the code, it works fine until I send a message to the bot, when I get this error:

joke_text = 'Yo '+user_details['first_name']+'..!' + joke_text
KeyError: 'first_name'

And facebook returns this:

> {u'error': {u'message': u'Invalid OAuth access token.', u'code': 190, u'type': u'OAuthException', u'fbtrace_id': u'HcT2M7LgPTY'}}
> {u'error': {u'code': 100,
>             u'error_subcode': 2018001,
>             u'fbtrace_id': u'ANUjQzx/PUi',
>             u'message': u'(#100) No matching user found',
>             u'type': u'OAuthException'}}

So, I don't know what to do know, as user's name is really important for my idea.
Thanks in advice

self.request.GET['hub.verify_token'] error

def get(self, request, *args, **kwargs):
		try:
			print(self.request.GET)
			token = self.request.GET['hub.verify_token']
		except MultiValueDictKeyError:
			print("hhhhhhhhhh")
			token = False

		if token == VERIFY_TOKEN:
			return HttpResponse(self.request.GET['hub.challenge'])
		else:
			return HttpResponse('Error, invalid token')

it returned <QueryDict: {}>

requests.get(user_details_url, user_details_params) - get() takes exactly 1 argument (2 given)

Getting the following error.

File "/app/jobmind/fb_bot/views.py", line 36, in post_facebook_message
user_details = requests.get(user_details_url, user_details_params).json()

TypeError: get() takes exactly 1 argument (2 given)

I am trying to implement your application but it gives me error in importing 4 modules.

fbbot/views.py", line 4, in
import json, requests, random, re
ImportError: No module named 'requests'
Can you solve this?

I do not get "hub.verify_token" in get request when i open url in browser

I have downloaded and setup your code and I have set up ngrok also and configured app on facebookdeveloper site but after all configuration when I am going to open https://6bc98399.ngrok.io/fb_yomamabot/66d2b8f4a09cd35cb23076a1da5d51529136a3373fd570b122/, then it will throw error.
