Flask-JWT似乎無法識別current_app

我想在我的應用程序中使用Flask-JWT。當我嘗試用current_app初始化它時，出現錯誤。到目前爲止，我一直使用current_app代替app = Flask(__name__)，所以這有點意外。有什麼我失蹤？Flask-JWT似乎無法識別current_app

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 
    File "./auth.py", line 59, in <module> 
    jwt = JWT(current_app, authenticate, identity) 
    File "/opt/mist_base/env/lib/python2.7/site-packages/flask_jwt/__init__.py", line 216, in __init__ 
    self.init_app(app) 
    File "/opt/mist_base/env/lib/python2.7/site-packages/flask_jwt/__init__.py", line 220, in init_app 
    app.config.setdefault(k, v) 
    File "/opt/mist_base/env/lib/python2.7/site-packages/werkzeug/local.py", line 343, in __getattr__ 
    return getattr(self._get_current_object(), name) 
    File "/opt/mist_base/env/lib/python2.7/site-packages/werkzeug/local.py", line 302, in _get_current_object 
    return self.__local() 
    File "/opt/mist_base/env/lib/python2.7/site-packages/flask/globals.py", line 51, in _find_app 
    raise RuntimeError(_app_ctx_err_msg) 
RuntimeError: Working outside of application context.

你期望current_app是什麼？（它不會被設置爲請求外的任何內容。）爲什麼在初始化擴展時不傳遞實際的應用程序？ – davidism

這是我在我的main.py： '從瓶進口瓶，藍圖，render_template，會話，重定向，url_for，逃生，請求中止 ... 應用=瓶（__ name__）的app.config .from_pyfile（「./ config.py」） ... app.register_blueprint（api_auth）' 到目前爲止，我在印象之下Flask會自動通過current_app傳播應用上下文。當我更新config.py時，我能夠在藍圖節點中看到我的常量值。 – goterpsgo

你需要之前，你實際上可以用它來初始化類的CURRENT_APP「。

current_app = Flask(__name__)
