服务功能未识别

Question

我有此服务：

function AddSuggestedPeersService($http, SITE_CONFIG) {
    console.log("I come in Add Suggested Peers Service");
    var addSuggestedPeers = this;
    addSuggestedPeers.addSuggPeer = function(peerID, mode) {
        // a service
        return response;
    }
}

然后我在这样的控制器中使用它：

peerHealthController.AddConfirm = function(peerID,mode,peerName){
        console.log("I come in Add Confirm");
        console.log("Peer ID =====" + peerID);
        var confirmPopup = $ionicPopup.confirm({
          title: '',
          cssClass : 'confirmBox',
          templateUrl: 'peers/add_peer_confirmation.template.html',
          buttons: [{
             text: 'NO, THANKS'
          }, {
             text: '<b>YES, PLEASE</b>',
             type: 'button-yes',
             onTap: function(e) {
               e.preventDefault();
               return AddSuggestedPeersService.addSuggPeer(peerID,mode);
             }
          }]
        });
      }

尽管它用于服务，但不能调用该方法，说不存在任何方法。

ionic.bundle.js:26794 TypeError: AddSuggestedPeersService.addSuggPeer is not a function
    at Object.onTap (peersLandingPage.controller.js:108)

我缺少什么语法？

您没有返回服务中的任何内容。为了解决此问题，只需返回变量" AddSuggestedPeersService"，那么您应该能够使用您的服务功能。

function AddSuggestedPeersService($http, SITE_CONFIG) {
console.log("I come in Add Suggested Peers Service");
var addSuggestedPeers = this;
addSuggestedPeers.addSuggPeer = function(peerID, mode) {
    // a service
    return response;
}
return addSuggestedPeers;
}
