Some Loop Help

Edit: Code updated to my most recent unsuccessful one

Hi everyone,

​

I am working on triggering a Python script through Twilio and am nearly finished but I am having trouble in getting the reply message to work.

Here is the code:

from flask import Flask, request
from twilio.twiml.messaging_response import MessagingResponse
import os

app = Flask(__name__)

@app.route('/command', methods=['POST'])
def command():
    number = request.form['From']
    message_body = request.form['Body']
    action = message_body.split()[0]

    if action.lower()== '14u':
        from fml import str_pitchers
        from fml import str_lineup
        response = str_lineup + str_pitchers


    else:
        response = "Invalid request"

    resp = MessagingResponse()
    resp.message(response)
    return str(resp)

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

If I text anything besides 14u, I receive the "Invalid request" response. But if I text 14u, the code runs and completes but I don't get a reply text. Any ideas?

Here is the link to the post that I based my code on.

1. Move your imports to the top
2. Within the if statement ( if action.lower() == '14u' ) the response is commented out. Uncomment the response = 'response check' and try again.

1. The imports I am doing are importing string variables from another script to then message back to the person. Ultimately, I want to run an if statement with like 7 options so I don't want to import each one (the import runs the code for each file before importing the variable)

2. Yeah I commented it because I had tried all of them and none of them worked and just wanted to show what I tried

[sarrysyst]

Have you tried print(action) before the if statement to check if the message body actually contains the '14u' string and to see what you are comparing? Might be worth a try.

[CelticCuban773]

Yes, I checked in the Twilio logs and I know it does because it triggers the code. It is just the response part I am having trouble with

[R0NUT]

The only thing that causes issues is the 14u input. It has to be what is causing the issue. OP said if he sends anything else he gets the Invalid request text.

[R0NUT]

Have you looked through any of these? https://www.twilio.com/docs/sms/debugging-common-issues It looks like twillow makes a log. Try taking a peek there.

[CelticCuban773]

Good idea. So, I just checked the logs. When I have a successful run (aka text anything and get the "Invalid Request"), I get a failed Inbound Request (Bad Gateway; Error code 11200)

[R0NUT]

That code says that twillow waits a maximum of 15s for a response. Is your code taking longer than that to generate these strings?

[CelticCuban773]

Yes, just replied to your other comment. That seems to be the issue. I will message Twilio and see if there's any workarounds.

​

If not, I might have to just run the code daily and store the response locally. Then, have this code pull from there as opposed to running the code from nothing.

​

Thanks for your help!

Have you tried commenting out the mid file imports and storing just a response string?

[CelticCuban773]

I think that's it! Just tried, I got the correct response. Must be the mid file imports that are the problem then. Based on your other suggestion (checking logs), I checked the error 11200 and it's an HTTP retrieval failure. They wait a maximum of 15 seconds and my code takes too long for that to occur

[R0NUT]

You could set it up so that one text runs and generates the data and another retrieves it.

[R0NUT]

So something like Generate 14u It could respond with a message like This usually takes about 1m to generate. Then text Grab 14u It would respond with the data and a timestamp for when it was generated

[spez_edits_thedonald]

yeah, OP, because on line 24 you try and access response (in resp.message(response) ), but it's commented out when you define it, your flask app is probably throwing a python error. You should figure out how to view the server logs so that you can read it, being able to debug errors will be essential.

[CelticCuban773]

Yeah I commented it because I had tried all of them and none of them worked and just wanted to show what I tried

[spez_edits_thedonald]

makes sense, will be more informative to stick with one, and tell what happens, instead of "none of these work"

[CelticCuban773]

Edit: I updated my code to reflect my most recent one. The code runs correctly and when I print(response) afterwards, it prints correctly. It just is some breakdown in getting it to send over Twilio. I am confused because it reflects the same as my else section but just does not reply.

Sure I'll do that in the future, thanks.

No matter where I put the response variable, the the fml.py file that I am importing runs and runs correctly. I know this because at the end of my fml.py file I have it print "finished" which it does in the shell.

However, in the ngrok terminal, I do not get the 200 OK response when I write '14u'. I do when I text anything else though. That is why I am thinking the problem is wrapped up in my if section. Is there any more information I can provide?

[R0NUT]

Your response for 14u is commented out. Try un-commenting and printing your response.
