我正在撤回一些路由依赖数据,并且JSON从服务器返回得很好,但我不确定如何在我的控制器中实际访问该对象。我尝试了一些不同的东西,例如将.then()置于解析之内,但这不起作用。
resolve: {
menus: function ($http) {
var httpSource = this.httpSource = location.protocol + '//' + location.hostname;
const url = `${this.httpSource}/api/package/menus`;
return $http.get(url);
}
}
我也试过这个
resolve: {
menus: function ($http) {
var httpSource = this.httpSource = location.protocol + '//' + location.hostname;
const url = `${this.httpSource}/api/package/menus`;
var menuData;
$http.get(url).then(response => {
menuData = response.data.Data;
})
return menuData;
}
}
我只是无法弄清楚如何将其加载到控制器属性中。
我试图遵循这一点,但变量未在构造函数中注入 - https://medium.com/opinionated-angularjs/advanced-routing-and-resolves-a2fcbf874a1c#.2xzq32cwo
我尝试用
加载它this.menuData = $state.current.resolve.menus;
我最终得到了这个对象。
"$http", function $stateProvider.state.state.resolve.menus($http)]
我确信我在这里缺少一些基本的东西,但是对Angular不熟悉,我看不到它。基本上,我的对象是完整的函数定义,而不是返回data.Data。
我的控制器构造函数。
static $inject = ['PackageService', '$stateParams', '$state', 'menus'];
constructor(packageService: Service.IPackageService, $stateParams, $state, DTOptionsBuilder, DTColumnDefBuilder, public logger: ILogger, public menus: any) {

这应该是我们的控制者:
namespace myNamespace
{
export class MyController
{
public MenuData: any[];
// strict notation support, for minification
static $inject = ['$scope', 'menus'];
// here we will get the resolved menus
constructor(
protected $scope: ng.IScope,
protected menus: ng.IHttpPromiseCallbackArg<any>)
{
this.MenuData = menus.data
}
}
}
这是我们的州
.state('home', {
url: "/home",
templateUrl: 'template.html',
controller: myNamespace.MyController,
controllerAs: 'Ctrl',
resolve: {
// real example returning some data from data.json
menus: function ($http) {
var url = "data.json";
return $http.get(url);
}
}
})
现在我们可以在模板
中使用上述内容<pre>{{Ctrl.MenuData | json }}</pre>

我并不完全理解你使用决心的方式,但这是我最近做的一个简单例子:
在我的服务中:
myApp.service('mainService', function ($http, $q) {
this.getStarWarsData = function() {
var myPromise = $q.defer();
$http({
method: "GET",
url: "http://swapi.co/api/people/"
}).then(function(response) {
var parsedResponse = response.data.results; //Your code will be different here depending on the object you're getting back
console.log(parsedResponse);
console.log("this is the type of the pr", typeof(parsedResponse))
//this bit below is just manipulating the parsed response to obtain the data I wanted
var emptyArr = [];
for(var i = 0; i < parsedResponse.length; i++) {
emptyArr.push({
Name: parsedResponse[i].name,
Eyes: parsedResponse[i].eye_color,
})
} myPromise.resolve(emptyArr);
})
return myPromise.promise;
}
})
和控制器
myApp.controller("myController", ["$scope", "mainService", function($scope, mainService){
$scope.getData = function() {
mainService.getStarWarsData()
.then(function(response){
console.log("this is a response in our controller", response)
$scope.peoples = response;
})
}
}]);
