我最近发布了一个详细的描述我面临的问题
here在SO。由于我不能发送实际的$ http请求，我使用超时模拟异步行为。从我的模型到视图的数据绑定工作正常，借助@Gloopy
现在，当我使用$ http而不是$ timeout(本地测试)时，我可以看到异步请求成功，数据在我的服务中用json响应填充。但是，我的观点不是更新。
更新Plunkr here
这是一个Plunk，做你想要的：

原文链接：https://www.f2er.com/angularjs/147827.html这个想法是，你直接使用promises和他们的“then”函数来操作和访问异步返回的响应。
app.factory('myService',function($http) {
var myService = {
async: function() {
// $http returns a promise,which has a then function,which also returns a promise
var promise = $http.get('test.json').then(function (response) {
// The then function here is an opportunity to modify the response
console.log(response);
// The return value gets picked up by the then in the controller.
return response.data;
});
// Return the promise to the controller
return promise;
}
};
return myService;
});
app.controller('MainCtrl',function( myService,$scope) {
// Call the async method and then do stuff with what is returned inside our own then function
myService.async().then(function(d) {
$scope.data = d;
});
});
这里是一个稍微复杂的版本，缓存请求，所以你只有第一次(http://plnkr.co/edit/2yH1F4IMZlMS8QsV9rHv?p=preview)：
app.factory('myService',function($http) {
var promise;
var myService = {
async: function() {
if ( !promise ) {
// $http returns a promise,which also returns a promise
promise = $http.get('test.json').then(function (response) {
// The then function here is an opportunity to modify the response
console.log(response);
// The return value gets picked up by the then in the controller.
return response.data;
});
}
// Return the promise to the controller
return promise;
}
};
return myService;
});
app.controller('MainCtrl',$scope) {
$scope.clearData = function() {
$scope.data = {};
};
$scope.getData = function() {
// Call the async method and then do stuff with what is returned inside our own then function
myService.async().then(function(d) {
$scope.data = d;
});
};
});
