Flask-Sijax回調函數「在請求上下文之外工作」

在回調函數中，我無法訪問flask.session，flask.g或諸如url_for（）之類的函數。他們都拋出一個錯誤，說我「在請求範圍之外工作」。Flask-Sijax回調函數「在請求上下文之外工作」

Debugging middleware caught exception in streamed response at a point where response headers were already sent.

我一直無法找出如何解決這個問題。任何幫助，將不勝感激。

粘貼您的代碼，即使您已經解決了您的問題。 – I159

這將是有益的，如果你發佈你的代碼，但嘗試包裝你這樣的代碼：

with app.app_context(): 
    # do stuff...

或也許這：

with app.test_request_context(): 
    # do stuff...
