how to send request on my flask app google colab

Question

How do I send a request from localhost to my google colab app? I want to test the functions of deepface api, because my computer is so bad for this, but i have a CORS trouble... I still tested this code on my computer, the error with CORS was also present, but the code below helped fix this problem

import argparse
import time
import uuid
import tensorflow

from flask import Flask, jsonify, request
from flask_cors import CORS, cross_origin
from flask_ngrok import run_with_ngrok
from deepface import DeepFace

tf_version = int(tensorflow.__version__.split(".")[0])

if tf_version == 2:
    import logging

    tensorflow.get_logger().setLevel(logging.ERROR)

if tf_version == 1:
    graph = tensorflow.get_default_graph()


app = Flask(__name__)
run_with_ngrok(app)

# Service API Interface
@app.route('/')
def index():
    return '<h1>Hello, world!</h1>'


@app.route('/analyze', methods=['POST'])
def analyze():
    global graph

    tic = time.time()
    req = request.get_json()
    trx_id = uuid.uuid4()

    print(req)
    if tf_version == 1:
        with graph.as_default():
            resp_obj = analyzeWrapper(req, trx_id)
    elif tf_version == 2:
        resp_obj = analyzeWrapper(req, trx_id)

    toc = time.time()

    resp_obj["trx_id"] = trx_id
    resp_obj["seconds"] = toc-tic

    return resp_obj, 200


def analyzeWrapper(req, trx_id=0):
    resp_obj = jsonify({'success': False})

    print(req)
    instances = []
    if "img" in list(req.keys()):
        raw_content = req["img"]  # list

        for item in raw_content:  # item is in type of dict
            instances.append(item)

    if len(instances) == 0:
        return jsonify({'success': False, 'error': 'you must pass at least one img object in your request'}), 205

    print("Analyzing ", len(instances), " instances")

    detector_backend = 'opencv'
    actions = ['emotion', 'age', 'gender', 'race']

    if "actions" in list(req.keys()):
        actions = req["actions"]

    if "detector_backend" in list(req.keys()):
        detector_backend = req["detector_backend"]

    try:
        resp_obj = DeepFace.analyze(instances, actions=actions)
    except Exception as err:
        print("Exception: ", str(err))
        return jsonify({'success': False, 'error': str(err)}), 205

    return resp_obj

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

I'm trying to do this:

app = Flask(__name__)
CORS(app, support_credentials=True)
run_with_ngrok(app)

and this:

def _corsify_actual_response(response):
    response.headers.add("Access-Control-Allow-Origin", "http://localhost:8080")
    return response

and a few more options, but none helped:( Pls help

P.S. my JS post:

axios
        .post('http://b3a6-35-237-77-168.ngrok.io/analyze', {})
        .then(function (response) {
            console.log(response);
        })
        .catch(function (error) {
            console.log(error);
        });
