我如何在“解决"方案内部使用工厂的$ stateProvider? [英] How can I use a factory inside a "resolve" of $stateProvider?
问题描述
作为标题,我想使用工厂坚持解决" app.js:
As title I want to use a factory insisde a "resolve" app.js:
angular
.module("goHenry", ["ui.router"])
.factory("httpPost", httpPost)
.controller("MainCTRL", ["$scope", MainCTRL]);
function MainCTRL($scope, httpPost){
this.nameApp = "CiaoMiao";
console.log($scope.children, httpPost);
}
function httpPost($http, $q){
return {
get: function() {
var deferred = $q.defer();
$http.post.apply(null, arguments)
.success(deferred.resolve)
.error(deferred.resolve);
return deferred.promise;
}
}//RETURN
}
routers.js:
routers.js:
var httpConfig = {headers:{ "Content-Type" : "application/x-www-form-urlencoded" }};
var config = ["$urlRouterProvider", "$stateProvider", function($urlRouterProvider, $stateProvider){
$urlRouterProvider.otherwise("/");
$stateProvider
.state("multi",{
url: "/multi",
"viewA@multi": {
templateUrl: "app/templates/login.htm",
controller: ["$scope", "getChildrenNumber", function($scope, getChildrenNumber){
this.nameApp = "nameAppChanged";
this.gatto = "Miao";
}],
controllerAs: "ctrl"
}
},
resolve: {
getChildrenNumber: ["$http", function($http, httpPost){
var httpP = httpPost.get("http://domain.com/user/login/api-login", $.param({ username:"ciaociao6@ciao.com", password:"ciaociA0" }), httpConfig)
console.log(httpP);
return "Some response from an API";
}]
}
});
angular
.module("CiaoMiao")
.config(config);
作为console.log的结果,我得到了未定义",在代码的这一部分,我不知道如何注入该工厂. 我试图放入该视图的主控制器中,但效果不佳.
As result of console.log I got "undefined", I don't get how to inject that factory at this part of the code. I tried to put into the main controller of that view, but it didn't work as well.
推荐答案
(如果将解决方案放在您的视图中,它将可以使用. 如果需要在同一状态的多个视图中进行解析.我会尝试使用抽象状态并在其中添加解析.)可以运行,但不是必需的(请参见下面的编辑.)
(If you place the resolve at your view it should work. If you need that resolve in multiple views of the same state. I would try to use an abstract state and add the resolve there.) Works but is not needed (see edit below.)
请查看以下 jsfiddle 或以下示例.
Please have a look at this jsfiddle or the demo below.
为了使内容更易于阅读,我对演示进行了一些简化.也没有在演示中为DI添加数组符号.
您无需在工厂中使用延迟的对象,因为$http
已经返回了诺言.
I've reduced the demo a bit to keep things easier to read. Also not added array notation for DI in the demo.
You don't need to use the deferred object in your factory because $http
is already returning a promise.
您可以将解决方案放置在视图之外,它也应该起作用.我已经在小提琴中进行了尝试. 因此,您的代码中可能存在另一个问题.
You can place the resolve outside of the view and it should work too. I've tried it in this fiddle. So there's probably a different issue in your code.
好的,我认为您的代码存在的问题是您没有从诺言中返回已解决的价值.类似于promise.then(function(response) {return response;});
OK, I think the problem with your code is that you're not returning the resolved value from your promise. Something like promise.then(function(response) {return response;});
angular.module('demoApp', ['ui.router'])
.factory('myDataFactory', function ($http) {
return {
get: function (id) {
return $http.post('http://crossorigin.me/http://www.mocky.io/v2/55a65562b2016ce10c7e6ea9', {
id: id
}).then(function (response) {
return response;
});
}
};
})
.config(function ($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/124');
$stateProvider.state('home', {
url: '/:id',
views: {
'viewA': {
template: '{{hello}}',
controller: 'homeController',
resolve: {
backendData: function (myDataFactory, $stateParams) {
return myDataFactory.get($stateParams.id);
}
}
},
'@': {
template: 'main view'
}
}
});
})
.controller('homeController', function ($scope, backendData) {
console.log(backendData);
$scope.hello = backendData;
});
