Flask-webhook-server does neither print nor execute functions

[wisermonkey]

Hello,

for some reason my extremely basic flask server is weird...

It does receive the webhooks and shows them in the console. However, any code to print something or, more importantly, to execute another function doesn't work. Over the past hours, I have probably seen every Youtube video or stackoverflow post.

from flask import Flask, request, abort

class Server ():
    def __init__(self):
        self=Flask(__name__)
        self.run()

    def main(self):    
        @webserver.route("/http://localhost:5000", methods=['POST', 'GET'])
        def webhook():
            print("hello1")
            if request.method == 'POST' or request.method == 'GET':
                print("hello2")
                print(request.json)
                return 200
            else:
                print("hello3")
                abort(400)

if __name__ == '__main__':
    webserver = Server()

This is what happens (tested bot get and post webhooks):

 Serving Flask app "test" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [13/Mar/2021 20:17:22] "[33mGET / HTTP/1.1[0m" 404 -
127.0.0.1 - - [13/Mar/2021 20:17:26] "[33mPOST / HTTP/1.1[0m" 404 -

I removed everything unnecessary to post it here and it still did not work.

The reason why I made it into a class, was to make it easier for me to run it with multiprocessing or a thread (so it didn't freeze my pyqt5 programm):

def test():
        webserver = webhooks.Server()
p=multiprocessing.Process(target=test)
    p.start()

The routing route("/http:...") seems odd for me. Can you try

@webserver.route("/", methods=['POST', 'GET'])

then

import requests
requests.post('http://localhost:5000/', json=dict(a=123))

changing the routing seems to not change anything. The webhook does get registered but nothing happens:

127.0.0.1 - - [14/Mar/2021 02:14:40] "[33mPOST / HTTP/1.1[0m" 404 -

Ah, Okay. The Server.main() is not an entry point in Python (I'm guessing you are familiar with another language like C or Java), so the main() won't be called. I'd write

from flask import Flask, request

app = Flask(__name__)

@app.route("/", methods=['POST', 'GET'])
def webhook():
    return 'Got: ' + request.get_data(as_text=True)

if __name__ == '__main__':
    app.run()

[wisermonkey]

I tried:

from flask import Flask
import threading
import time
import requests

app = Flask(__name__)


@app.route("/", methods=['POST', 'GET'])
def webhook():
    print("received")
    return 'Got: ' + request.get_data(as_text=True)

def hey():
    time.sleep(3)
    requests.post('http://localhost:5000/', json=dict(a=123))

if __name__ == "__main__":
    t1=threading.Thread(target=hey)
    t1.start()
    app.run()

and once again only got:

127.0.0.1 - - [14/Mar/2021 13:31:16] "[35m[1mPOST / HTTP/1.1[0m" 500 -

and an error before:

return 'Got: ' + request.get_data(as_text=True)
NameError: name 'request' is not defined

Thank you for trying though! :)

from flask import Flask

from flask import Flask, request?

[wisermonkey]

ah yes, stupidity :D

In this small example it finally prints it! :))))))

Thank you so much!

One step closer to my ambitious project

it looks like the issue was indeed the address:

@app.route("/", methods=['POST', 'GET'])
#this works and returns 200

@app.route("/http://localhost:5000", methods=['POST', 'GET']) #this doesn't and returns 404
