我有一個帶有init .py的燒瓶應用程式。在 create_app 函式中，我設定了app.config['UPLOAD_FOLDER']. 我需要將應用程式匯入到我的 post.py 檔案中，該檔案具有將從中上傳和下載檔案的路由。我嘗試的每種型別的匯入都遇到問題。
初始化.py：
from flask import Flask, session, redirect, url_for
from bson.objectid import ObjectId
from pymongo import MongoClient
from os import path, mkdir
from flask_login import LoginManager
client = MongoClient()
db = client.Contractor
def create_app():
app = Flask(__name__)
app.config['SECRET_KEY'] = ''
upload_folder = 'uploads/'
if not path.exists(upload_folder):
mkdir(upload_folder)
from .views import views
from .auth import auth
from .post import post
app.config['MAX_CONTENT_LENGTH'] = 1 * 1024 * 1024
app.config['UPLOAD_FOLDER'] = upload_folder
app.register_blueprint(views, url_prefix='/')
app.register_blueprint(auth, url_prefix='/auth/')
app.register_blueprint(post, url_prefix='/post/')
return app
后.py：
from flask import Blueprint, render_template, request, flash, redirect, url_for, session
from datetime import datetime
from werkzeug.security import generate_password_hash, check_password_hash
from werkzeug.utils import secure_filename
from . import db
from bson.objectid import ObjectId
from os import path, mkdir
@post.route('/upload', methods=['GET', 'POST'])
def create_post():
if 'username' in session:
current_user = db.users.find_one({ 'username' : session['username']})
if request.method == 'POST':
data = request.form
photo = request.files['photo']
print(photo)
---->photo.save(path.join(app.config['UPLOAD_FOLDER'], secure_filename(photo.filename)))
caption = data.get('caption')
location = data.get('location')
如何從init .py匯入應用程式

我認為您可以app在匯入 db 的位置匯入。
from . import app, db
