Flask-JWT似乎无法识别current_app

Question

我想在我的应用程序中使用Flask-JWT。当我尝试用current_app初始化它时，我得到一个错误。到目前为止，我已经成功地使用current_app代替了app = Flask(__name__)，所以这有点出乎意料。我是不是漏掉了什么？

main.py

from flask import Flask

app = Flask(__name__)
app.config.from_pyfile("./config.py")

from app import api_auth
app.register_blueprint(api_auth.bp)

api_auth.py

from flask import current_app
from flask_jwt import JWT

def authenticate(username, password):
  ...
  return user

def identity(payload):
  ...
  return userid_table.get(user_id, None)

jwt = JWT(current_app, authenticate, identity)

Traceback (most recent call last):
  File "./wsgi.py", line 1, in <module>
    from main import app as application
  File "./main.py", line 5, in <module>
    from auth import api_auth

    jwt = JWT(current_app, authenticate, identity)

    return self.__local()

你需要先初始化你的类'current_app‘，然后才能实际使用它。

current_app = Flask(__name__)
