角JS决心下决心 [英] Angular JS resolve in a resolve

问题描述

我的意思了决心决心是，我希望能够先解决用户，然后解决他所有的其他信息，如addressess，联系人，朋友。

What I mean by resolve in a resolve is that I want to be able to resolve the user first, and then resolve all his additional info, eg, addressess, contacts, friends.

我目前有：

.state('website', {
            url : '',
            abstract : true,
            resolve : {
                // Request the current signed in user >
                current_user : ['Auth', function(Auth){
                    return Auth.requestUser();
                }]
            },
            views : {
                'main' : {
                    templateUrl : 'template.html'
                }
            }
        })

我会喜欢做的是以下内容：

What I'll like to do is the following:

.state('website', {
            url : '',
            abstract : true,
            resolve : {
                // Request the current signed in user >
                current_user : ['Auth', function(Auth){
                    Auth.requestUser().then(function(){
                       // HERE I WANT TO RESOLVE OTHER RESOURCES
                       // WHAT WILL I RETURN HERE?
                    });
                }]
            },
            views : {
                'main' : {
                    templateUrl : 'template.html'
                }
            }
        })

我不知道这是可能的。

I'm not sure if this is possible.

推荐答案

您可以注入解析参数到其他的决心功能：

You can inject "resolved" parameters into other resolve functions:

resolve: {
  current_user: ['Auth', function(Auth){
    return Auth.requestUser();
  }],

  // "Svc" here is some service I assume you have to get friends, address, etc...
  friends: ["Svc", "current_user", function(Svc, current_user){
     // Svc.getFriends can return a promise or a value
     return Svc.getFriends(current_user);
  }],

  address: ["Svc", "current_user", function(Svc, current_user){
     return Svc.getAddress(current_user);
  }]
}

然后，在控制器的状态，你可以注入 CURRENT_USER ，朋友和地址作为参数：

.controller("WebsiteMainViewCtrl", function($scope, current_user, friends, address){
   // ...
})
