秘密密钥没有在烧瓶会议中设置
我有一个运气在Flask（一个Python模块）中运行的运气。
现在我正在使用烧瓶第三方库Flask-Session
当我连接到我的网站时，出现以下错误：
RuntimeError：会话不可用，因为没有设置密钥。 将应用程序上的secret_key设置为独特和秘密的内容。
以下是我的服务器代码。
from flask import Flask, session from flask.ext.session import Session SESSION_TYPE = 'memcache' app = Flask(__name__) sess = Session() nextId = 0 def verifySessionId(): global nextId if not 'userId' in session: session['userId'] = nextId nextId += 1 sessionId = session['userId'] print ("set userid[" + str(session['userId']) + "]") else: print ("using already set userid[" + str(session['userId']) + "]") sessionId = session.get('userId', None) return sessionId @app.route("/") def hello(): userId = verifySessionId() print("User id[" + str(userId) + "]") return str(userId) if __name__ == "__main__": app.secret_key = 'super secret key' sess.init_app(app) app.debug = True app.run() 正如你所看到的，我确实设置了应用密钥。 我究竟做错了什么？
是否有其他会议选项？
其他信息：在Linux Mint上运行Python 2.7

NullSessionInterface会话实现引发了exception，这是您使用Flask-Session时的默认会话types 。 那是因为你实际上没有给SESSION_TYPEconfiguration给Flask ; 在模块中将其设置为全局是不够的 。
对于Flask 0.10，这个默认值没什么意义。 它可能对Flask 0.8或0.9有意义，但当前版本被用作错误信号。 在你的情况下，它现在给你错误的错误信息。
将SESSION_TYPEconfiguration选项设置为其他值。 selectredis ， memcached ， filesystem或mongodb 。
将其设置为filesystem是最简单的; 那里有足够的默认configuration可以在没有额外依赖的情况下工作：
if __name__ == "__main__": app.secret_key = 'super secret key' app.config['SESSION_TYPE'] = 'filesystem' sess.init_app(app) app.debug = True app.run()
设置if __name__ == '__main__':之外的密钥if __name__ == '__main__':
from flask import Flask, session app = Flask(__name__) app.secret_key = "super secret key" @app.route("/") ... if __name__ == '__main__': app.debug = True app.run()
尝试这个：
app = Flask(__name__) app.config['SESSION_TYPE'] = 'memcached' app.config['SECRET_KEY'] = 'super secret key' sess = Session()
并删除底部的app.secret_key作业。
