RECAPTCHA_PUBLIC_KEY配置未設置Flask-WTForms

Question

當聯繫頁嘗試在Flask中使用帶wtforms的Recaptcha加載時，我已經遍歷了文檔並不斷收到'RuntimeError：RECAPTCHA_PUBLIC_KEY config not set'。我願意接受任何建議。我使用Google的ReCaptcha 2，FWIW在Ubuntu 14.04上運行Flask。

編輯：這個問題已經用dirn的建議解決了，但我現在正在得到一個KeyError消息，儘管公鑰和私鑰被正確輸入。

這是我的堆棧跟蹤。

您不添加配置設置的應用程序。您正在定義模塊級變量

RECAPTCHA_USE_SSL = False 
RECAPTCHA_PUBLIC_KEY = 'public' 
RECAPTCHA_PRIVATE_KEY = 'private' 
RECAPTCHA_OPTIONS = {'theme': 'white'} 

您需要使用名稱作爲配置字典的鍵。

app.config['RECAPTCHA_USE_SSL'] = False 
app.config['RECAPTCHA_PUBLIC_KEY'] = 'public' 
app.config['RECAPTCHA_PRIVATE_KEY'] = 'private' 
app.config['RECAPTCHA_OPTIONS'] = {'theme': 'white'}
