javascript - flask-security ajax 注销导致 session 错误

Question

当我发布到 flask 端点时:

@app.route('/api/v1/logout', methods=['POST','GET'])
def logout():
    logout_user()
     return jsonify(status=200, message='User has been successfully logged out.')

下次尝试登录时出现错误

InvalidRequestError: Object '<User at 0x7f09b4831c90>' is already attached to session '1' (this is '4')

我想知道如何注销并安全地使用 ajax。

编辑- angularjs 登录 Controller :

LoginController: function ($scope, $http, authService, $location) {
    $scope.submit = function() {
      console.log('in logincontroller')
      $http.defaults.headers.post['X-CSRFToken'] = csrf_token;
      $http.defaults.headers.common['Content-Type'] = 'application/json'
      //debugger;
      $http.post(
    '/login',
      JSON.stringify({ email: $scope.email, password: $scope.password })
      ).success(
    function(data) {
      if (data.meta){
        var status_code = data.meta.code;
      }
      else{
        var status_code = data.status;
      }
      if (status_code == 200){        
        $.cookie('email', $scope.email, { expires: 7 });
        $.cookie('auth_token', data.authentication_token, { expires: 7 });
        $http.defaults.headers.common['Authentication-Token'] = data.authentication_token;
        authService.loginConfirmed();
        $location.path("/dashboard");
      }
      else{
     //form stuff
      }
    }
    ).error(
    function(data) {
      alert('LoginController submit error');
      $scope.errorMsg = data.reason;
      //debugger;
    }
      );
    };
  }

我想你必须在最后重定向才能退出现有 session

@app.route('/logout')
def logout():
    # remove the username from the session if it's there
    session.pop('username', None)
    return redirect(url_for('index'))
