I want to pop an alert message for error handling on an app that runs via Google App Engine for Python.
I tried this already but non worked:
from Tkinter import *
msg = Message(text="Please, make sure you fill out the boxes and agree with the terms")
msg.config(bg='green', font=('times', 16))
msg.pack()
mainloop()
AND
import win32api
win32api.MessageBox(0, 'hello', 'title')
I am guessing the Google App Engine has its own way of handling this task but I can't figure out how.
Thank you!
You can't do that. The GAE server suppose to run headless, so you can't display a popup in your host machine. If you use windows to launch de dev server, simply use the log buton from the GUI or launch your dev server from the command line.
To generate a debug log from your application you can simply see this post. Google app engine logging in dev consol
In production your application have a full admin panel with a lot of possibilities and a logging pannelto see all messages from your app.

Hello Fellow Slack Bot Enthusiasts.
It's my first time to start setting up a Slack Bot (and I don't have a lot of dev experience, so I wanted to inquire!) .
For this, I used python and Slack bolt.
Background
I was trying to setup my Amazon EC2 Web Instance's Load Balancer to accept slack events from my Workspace. In the below photo, I am now able to have my Endpoint URL Verified in the Slack bot.
Next, I am trying to follow the instructions listed in the Slack Bolt homepage that told me to create the app.py test file. So I followed through on the instructions and ensured that I subscribed to below events:
app_home_opened
message.channels
message.groups
message.im
Then I created the sample app.py file from the article, that was supposed to handle the app_home_opened event.
Now I tried to run the application in my command line (I added the section for #app.event(app_home_opened), and all the other required events ), and I tried to trigger the app_home_opened, message.channels, message.im events, by opening the home page of my bot and by dm-ing the bot and inviting it to a channel and trying to talk to it - but I don't seem to be receiving any payload in the back-end.
I wanted to inquire about the "Verified" notification from the Slack Bot. Does this ensure that the connection between my chatbot code and the server are actually linked?
In addition, I wanted to inquire about ways to test this so that I can ensure that the connection is actually working as expected.
If you could share some thoughts about what I can do to test the communication, it would be much appreciated. Thank you!
Summary
TLDR:
Problem: My chatbot is not receiving any payload from Slack.
Expected: I think there should be some interaction saying HTTP / 200 response to indicate that it is OK, etc.
Actual: The chatbot just remains the same saying "⚡Bolt App is Running"
What I've tried:
Reinstalling the application to ensure that all my changes were saved and were reflected properly in my Slack Environment
Testing the communication by curling through to the URL (it responded with challenge parameter), so I thought that it was OK
Testing the communication by entering some text via DM / channel communication, and opening the homepage.
Sample Code:
import os
# Use the package we installed
from slack_bolt import App
# Initializes your app with your bot token and signing secret
app = App(
token=os.environ.get("SLACK_BOT_TOKEN"),
signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
)
# Add functionality here
# #app.event("app_home_opened") ...
# added some of the code from the guide here and the other #app.events ("")
# Start your app
if __name__ == "__main__":
app.start(port=int(os.environ.get("PORT", 3000)))
slack_bolt, for some reason that escapes me, does not seem to create the event handler endpoint (/slack/events) and instead seems to prefer running the application in socket mode. It may still be worth looking into socket mode (see SocketModeHandler) but this example from slack_bolt's github repo ended up getting me to my solution: https://github.com/slackapi/bolt-python/blob/main/examples/flask/app.py
The short-ish version is you have to utilize slack_bolts's flask adapter to create a SlackRequestHandler then create a flask app, define the slack events endpoint (/slack/events) for the flask app, and pass the result to the bolt SlackRequestHandler (Events Endpoint -> Flask -> SlackRequestHandler -> Bolt):
import os
from flask import Flask, request
from slack_bolt import App
from slack_bolt.adapter.flask import SlackRequestHandler
bolt_app = App(
token=os.environ.get("SLACK_BOT_TOKEN"),
signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
)
flask_app = Flask(__name__)
handler = SlackRequestHandler(bolt_app)
# Add functionality here
# #bolt_app.event("app_home_opened") ...
# added some of the code from the guide here and the other #bolt_app.events ("")
#flask_app.route("/slack/events", methods=["POST"])
def slack_events():
return handler.handle(request)
if __name__ == "__main__":
flask_app.run()
Hope this helps, cheers!
Im trying to scrape Reddit with the praw.reddit command and I keep getting the following:
prawcore.exceptions.OAuthException: unauthorized_client error processing
request (Only script apps may use password auth)
Heres the top of my code:(I removed the sensitive items)
import praw
import pandas as pd
import datetime as dt
reddit = praw.Reddit(client_id='zlpcoz08aNK8Bw', \
client_secret='', \
user_agent='comment_scraper 1.0 by /u/bullybear77777',
\
username='', \
password='')
I think it's because of my user_agent ID? I looked online and found that this appears to be the structure but im not sure. Any helps here would be greatly appreciated
This sort of error is caused by the type of app associated with that client id. Logging in with a password is restricted to script type apps.
When you create a new application, there are three types of apps to choose from:
web app: A web based application
installed app: An app intended for installation, such as on a mobile phone
script: Script for personal use. Will only have access to the developers accounts
If the application has the web app or installed app types then this form of authentication can't be used. You can't change the app type once it's created, but you can simply create a new one with a script type.
I'm trying to get Flask-Mail setup on in Flexible ENV on Google App Engine. Flask-Mail works on my localhost using the credentials for a domain I am trying to use to send the mail. However, when using it on GAE through my API it returns a 502 error, however it shows no error messages in the logs or console. Going through the documentation for GAE Flexible it doesn't mention anything about NOT being able to use it, however it doesn't show how one would setup Flask-Mail either.
I have this..
mail = Mail()
print('1') // We Get here
msg = Message("Hello",
sender="me#mydomain.com",
recipients=["me#mydomain.com"])
print('2') // We get here
msg.body = 'Testing'
print('3') // We get here
mail.send(msg)
print('4') // This never gets call because I timeout on a 502 before this
I can tell I am not getting any fatal errors because the app stays working. However this fails with the 502. I have tried adding my email to the list of authorized senders but it doesn't seem to have helped.
I would appreciate any feedback. If I forced to use a 3rd party service to send mail it may cause me to move the project off of GAE.
As Ivan posted on his comment, to send email from a GAE app you need to use a mail service. Right now there are 3 options for apps on a flexible environment: Mailgun, MailJet and SendGrid. Choose the one you see better for your app.
After setting up an account on the mail service you have chosen, you have to prepare your code by integrating the parts related to the mail service.
These tutorials should help you establish the mail service for your app:
Mailgun
MailJet
SendGrid
I've had the same error but on a virtual machine on the internet ( linode service ) and it turned out that it has some thing to do with rDNS and some domain name config that you have to set up for your Ip address to get things working correctly , check this

My program download some infos about user and post it to the label in app.
I have a interaction/authorization problem with gui Facebook app in python. My app uses tkinter, facebook and fbconsole.
I autorized in this way.
import fbconsole as F
F.APP_ID="123"
F.AUTH_SCOPE=['publish_stream', 'publish_checkins', 'read_stream', 'offline_access']
F.ACCESS_TOKEN = "1234"
F.authenticate()
And something for show results
newsfeed = F.get('/me/home', {'fields':'from,name,description,message'})
newsfeedData = newsfeed["data"]
label.config(text=newsfeedData)
But when I run it, appear new facebook tab in browser announce: "Application configuration does not allow the use of the URL". How can I get rid of it?
Thanks!
I am writing a python desktop app that will access a user's facebook photos. The app currently supports flickr, which uses a similar oauth authentication process, but I am struggling to figure out how to authenticate the app for facebook. For flickr, the basic steps are:
App opens a browser on the authentication page
user gives the app permission to access the account
App receives a token as a http response that can then be used with flickr's api
I am hoping that there is something similar for facebook, but I haven't been able to figure it out.
There are a variety of facebook API libraries for python, such as Pyfb, which provides a simple way of accessing graph data, but none of them provide an obvious way to do the authentication steps above and retrieve a token that can be used. Here's the example from Pyfb, which presumes that the user token will be manually entered by the user, which is totally ridiculous for a desktop app...
from pyfb import Pyfb
#Your APP ID. You Need to register the application on facebook
#http://developers.facebook.com/
FACEBOOK_APP_ID = 'YOUR_APP_ID'
pyfb = Pyfb(FACEBOOK_APP_ID)
#Opens a new browser tab instance and authenticates with the facebook API
#It redirects to an url like http://www.facebook.com/connect/login_success.html#access_token=[access_token]&expires_in=0
pyfb.authenticate()
#Copy the [access_token] and enter it below
token = raw_input("Enter the access_token\n")
#Sets the authentication token
pyfb.set_access_token(token)
#Gets info about myself
me = pyfb.get_myself()
Here's a shot at answering my own question.
First, the reason the code fragment above doesn't work. The call to pyfb.authenticate opens the authentication link in the default browser. After the user logs in and allows the app access, facebook is supposed to redirect the URL in the browser to something like
https://www.facebook.com/connect/login_success.html#access_token=ACCESS_TOKEN&
expires_in=SOMETIME
In the pyfb code sample, the user is supposed to copy the access token from the URL bar and all should be well. But... presumably because of some security concerns, facebook will perform some Javascript shenanigans which will instead leave you with:
https://www.facebook.com/connect/blank.html#_=_
(It turns out that you can work around this by digging through the browser history on some browsers -- see https://bugs.kde.org/show_bug.cgi?id=319252)
The solution to this for a desktop app is to open a web view within the app. The Javascript code apparently will correctly detect you are authenticating within an app and spit out the full URL with token. So here's an example using Python gtk and webkit:
import gtk
import webkit
view = webkit.WebView()
sw = gtk.ScrolledWindow()
sw.add(view)
win = gtk.Window(gtk.WINDOW_TOPLEVEL)
win.add(sw)
win.show_all()
win.connect("destroy", lambda *args:gtk.main_quit())
client_id = 'XXXXXXXXXXXXX' #your unique app id
auth_url = 'https://www.facebook.com/dialog/oauth?response_type=token&client_id=%s&redirect_uri=https://www.facebook.com/connect/login_success.html'%(client_id,)
view.open(auth_url)
def load_finished(view,frame):
#function will print the url with token second time
print frame.get_uri()
view.connect("document-load-finished",load_finished)
gtk.main()
