401 (Unauthorized) error

[krajkumar6]

Below is my angular js service function( Where auth2 is the google api auth object) and after that is my server passport strategy code. I'm unable to authenticate using headers or params in my http request and keep getting unauthorized error.

this.glogin =function(){
        var deferred = $q.defer();.
        auth2.signIn({
          'scope': 'profile email'
        }).then(function(response){
            self.gUser=response;
            self.accesstoken = self.gUser.getAuthResponse().access_token;
            $cookies.put('acctoken',self.accesstoken);
            $log.log('self.accesstoken',self.accesstoken);
               $http({
                method: 'GET',
                url:"/auth/google/accesstoken",
                //params:{access_token : self.accesstoken},
                headers:{
                 access_token : self.accesstoken
                }
                }).then(function successCallback(srresponse){
                  
                  self.userobj=srresponse.data;
                  $log.log('google passport authenticated user:',srresponse.data);
                  $cookies.putObject('usrobj',srresponse.data);
                  deferred.resolve(self.userobj);
            
                },function errorCallback(srresponse){
                  $log.error("http request for user login failed");
                  deferred.reject(srresponse.statusText);
              }); //$http google+
        });
               
        return deferred.promise;
    };//glogin
