大型应用程序的烧瓶结构[关闭]

Question

我有一个带有视图的有点令人毛骨悚然的文件：

from app import app
from flask import request

inspection_handler = None
data_handler = None
repeat_handler = None

@app.route(START_URL + 'inspection/', methods=['GET'])
def inspection():
    return inspection_handler.update(request)


@app.route(START_URL + 'data/', methods=['GET'])
def data():
    return data_handler.update(request)


@app.route(START_URL + 'repeat/', methods=['GET'])
def repeat():
    return repeat_handler.update(request)

另一个模块有这样的代码：

from app.handlers.data.data_handler import DataHandler
import app.views.monitoring as monitoring

monitoring.data_handler = DataHandler()

我认为我确实可以改进第一个模块，但我不知道如何正确地做到这一点。你能帮帮我吗？

看看flask blueprints，和已经推荐的Flask - Structuring Large Apps

from app import app  
from flask import Blueprint, request


handlers = {
    'inspection': None,
    'data': None,
    'repeat': None
}


handler_page = Blueprint(START_URL, __name__)
# Ideally register this blueprint where you registered your app
app.register_blueprint(handler_page)


@handler_page.route('/<string:handler_type>', methods=['GET'])
def handler_view(handler_type):
    try:
        curr_handler = handlers[handler_type]
    except KeyError:
        return "Not found.", 404
    return curr_handler.update(request)
