Question

Я создаю PWA, используя React в качестве внешнего интерфейса и Flask для размещения сервера.

Это файл flask:

    import flask
    from flask import jsonify, request, render_template, redirect, abort
    import os
    import sys
    import OCR.text_from_im as OCR
    import time
    import json
    import database.db_func as db
    debug = False

    db.create_table()


    def log_error(*args):
        s = "[" + time.strftime("%d-%m %H:%M:%S") + " IST]   "
        for arg in args:
            s += str(arg) + " "
        s += "\n\n"

        if debug:
            print(s)
        else:
            with open(os.path.join(os.getcwd(), "error_logs", "flask.log"), "a+") as f:
                f.write(s)

    # function to join all the websites


    def join(lst, sep):
        print("[LIST] ", str(lst))

        s = ''
        for i in range(len(lst) - 1):
            s += lst[i] + sep

        s += lst[-1]

        return s


    app = flask.Flask("__main__")

    # Frontend route
    @app.route("/")
    @app.route("/Answer")
    @app.route("/Answer/answer0")
    @app.route("/Answer/answer1")
    @app.route("/Answer/answer2")
    @app.route("/Answer/answer3")

    @app.route("/Picture")
    @app.route("/Safari")
    @app.route("/Saved Answers")
    @app.route("/Settings")
    @app.route("/Tutorial")
    @app.route("/Unknown")
    def main():
        return render_template("index.html")

    # Route where image is sent
    @app.route("/OCR", methods=['POST', 'GET'])
    def get_question():
        try:
            img = request.get_json()

            question = OCR.text_from_image(img['img'])
            # question = "brainly man running"

            print(f"\n\n\n\n, [QUESTION]: {question}\n\n\n")

            return jsonify({'question': question})
        except Exception as e:
            log_error(e)
            abort(500)

    # Route where question is sent
    @app.route("/scrapy", methods=['POST', 'GET'])
    def get_answer():
        try:
            websites = ["stackexchange.com", "doubtnut.com",
                        "askiitians.com", "brainly.in"]

            current_dict = {}
            question = request.get_json()

            _id = int(time.time())

            db.add_question(question["question"], _id)

            question["question"] = join(
                (question["question"].split()[:15]), "+").replace(".", "")

            question["question"] = question["question"].replace(" ", "+").replace(
                "\\n", "+").replace("\\t", "+").replace("\n", "+").replace("(", "+").replace(")", "+")
            print(
                f'scrapy crawl spider -a question={question["question"]} -a subject=revisionNotes  -a _id={_id}')
            os.system(
                f'scrapy crawl spider -a question={question["question"]} -a subject=revisionNotes  -a _id={_id}')

            success = True

            while db.get_status(_id) != 1:
                if db.get_status(_id) == -1:
                    success = False
                    break

            print("\n\n\n")
            db.prt()
            print("\n\n\n")

            ans = db.get_answer(_id)

            print("\n\n\n" + str(ans) + " - " + str(type(ans)) + "\n\n\n")

            if ans["success"] and success:
                current_dict["question"] = question["question"]
                current_dict["answers"] = ans["answer"]
                current_dict["websites"] = ans["domain"]
            else:
                current_dict["question"] = question["question"]
                current_dict["answers"] = "ERROR"
                current_dict["websites"] = "NOT FOUND"

            return jsonify(current_dict)
        except Exception as e:
            log_error(e)
            abort(500)


    @app.errorhandler(404)
    def error404(error):
        return redirect("/Unknown")


    app.run(host="0.0.0.0")

Работает нормально, если вы открываете приложение прямо в браузере, но при установке в телефоне в качестве PWA оно открывается на /static/react, а не /.

Есть ли место, где здесь должен быть указан маршрут открытия?
