angularjs 如何在controller中使用service

Service代码：

app.service('getTicketList', function($q, $http){
    this.data = {};
    this.getData = function(id){
        var deferred = $q.defer();
        var path='ticket.action?method:projectTickets';
        if(id)
            path+='&projectId='+id.toString();
        $http.get(path).then(function(d){
            //success
            this.data = d;
            deferred.resolve(d);
        },function(){
            //failure
            deferred.reject(d);
        });
    }
});

controller代码：

app.controller('projectController', function($scope,getTicketList) {
    $scope.tickets=getTicketList.getData($scope.projectId).data.tickets;
});

controller的那句代码有问题。我用getTicketList.data也获取不到数据，是{}。而且不知道怎么把参数传进去。。。。

你应该使用promise模式：

app.service('getTicketList', function ($q, $http) {
  this.data = {};
  this.getData = function (id) {
    var deferred = $q.defer();
    var path = 'ticket.action?method:projectTickets';
    if (id) {
      path += '&projectId=' + id.toString();
    }
    return $http.get(path).then(function (d) {
      this.data = d;
      return $q.when(d);
    }, function (d) {
      return $q.reject(d);
    });
  }
});

app.controller('projectController', function ($scope, getTicketList) {
  getTicketList.getData($scope.projectId).then(function (res) {
    $scope.tickets = res.tickets
  }, function (rej) {
    // error handler
  });
});

1.service里面用return代替this

javascriptapp.service('getTicketList', function ($q, $http) {
  var data = {};
  return {
    getData: function (id) {
      var deferred = $q.defer();
      var path = 'ticket.action?method:projectTickets';
      if (id)
        path += '&projectId=' + id.toString();
      var promise = $http.get(path).then(function (response) {
          return response;
      }, function (response) {
          return response
      });
      return promise;
    }
  }
});

2.调用的时候使用promise模式

javascriptgetTicketList.getData($scope.projectId).then(
  function (res) {
    $scope.tickets = res.tickets
  }, 
  function (rej) {
  // error handler
  }
);

这种传递参数的方式是不对的，没这么用过，这里有个项目，找到对应的controller.service看看
