现在,我正在使用烧瓶第3方库Flask-Session,但没有运气可以正常工作。
当我连接到我的站点时,出现以下错误:
RuntimeError:会话不可用,因为未设置任何秘密密钥。将应用程序上的secret_key设置为唯一且秘密的内容。
下面是我的服务器代码。
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()
如您所见,我确实设置了应用密钥。我究竟做错了什么?
还有其他会话选项吗?
