Question

我收到错误AttributeError: 'SecureCookieSession' object has no attribute 'Session'。我想创建基于令牌的身份验证。我通过一些服务获得令牌，这不是我关注的问题，但问题是我遇到了属性错误。

from flask import session, abort
from functools import wraps    
app =Flask(__name__)    
def authenticated_resource(function):
    @wraps(function)
    def decorated(*args, **kwargs):
        if session.get("authenticated"):
            return function(*args, **kwargs)
        return abort(403) # unauthenticated
    return decorated  
@app.route('/login', methods=['GET', 'POST'])
def login():
  error=None
  if request.method=='POST':
    if request.form['username']!='admin' or request.form['password']!='1234':
      error ='Invalid Credentials. Please try again.'
    else:          
      username=request.form['username']
      password=request.form['password']
      print 'username=', username
      print 'password=', password          
      auth_url='http://192.168.206.133:5000/v2.0'
      token = getToken(username=username, password=password, tenant_name=tenant_name)

      session["authenticated"] = True
      session["auth_token"] = token_dict

      return redirect(url_for('getstats'))
  return render_template('login.html', error=error)

@app.route('/metering')
@authenticated_resource
def getstats():
    token =session.get("auth_token")
    print 'token=',token
    return render_template('metering.html') 

@app.route('/projects')
def get_projects():
    auth=v2.Password(auth_url="http://192.168.206.133:5000/v2.0/", username="admin", password="1234", tenant_id='020377f522324546b072af92862e6466')
    sess=session.Session(auth=auth,verify=False)
    nova = client.Client(2, session=sess)
    instances =nova.servers.list()  
    def serializer(m):

      ret['Name']=m.name

      'project':[{'Id':'project', 'Name':'project'}] # Here added project option for group_by select option, 
       #previously It was showing only instance option, but now it is also show project option
    }
    return jsonify(context)

   app.secret_key='super secret key'
   #app.config['SESSION_TYPE']='filesystem'
   app.debug= True
   app.run(host='0.0.0.0',port=5001)

Answer 1

您已导入Flask的session对象。您似乎也期望session引用包含Session类的其他内容。你需要修复你的导入，这两者是截然不同的。您可以为其中一个导入添加别名，以使名称不重叠。或直接导入Session课程。

from keystoneclient import session as ksc_session
ksc_session.Session(...)

# or

from keystoneclient.session import Session
Session(...)

AttributeError：＆＃39; SecureCookieSession＆＃39;对象没有属性＆＃39; Session＆＃39;
