问题描述
在我的服务器端（ASP.ne MVC）我有方法，它看起来像这样：
on my server side (ASP.ne MVC) I have method which looks like this:
[HttpGet]
public JsonResult GetTrenings(string treningId)
{
var tempId = Guid.Parse(treningId);
var trening = TreningService.GetTreningById(tempId);
_trenings = TreningService.GetAllTreningsForUser(trening.UserId);
return Json(_trenings, JsonRequestBehavior.AllowGet);
}
和我有角服务：
publicApp.angularModule.factory('feedSingleTreningService', function ($q, $http) {
return {
getTrenings: function (data) {
var input = $http.get("/Feed/GetTrenings", { params: { treningId: data } });
var deferred = $q.defer();
deferred.resolve(input);
return deferred.promise;
},
};
});
在我的控制器我这样调用这个服务：
And In my Controller I call this service like this:
feedSingleTreningService.getTrenings(data).then(function(results) {
console.log("test", results);
});
但没有什么是在控制台中显示，我已经调试服务器端请求到达它，它返回_trenings，也服务返回的承诺，但没有任何反应。
But nothing is shown in console, I've debugged server side and request reaches it, and it returns _trenings, also service returns promise, but nothing happens.
我已经改变，那么最终，在控制台的测试结果显示，但结果是不确定的。
I've changed then to finally, and in console "test" was shown but results were undefined.
为什么会出现这种情况？
Why is this happening ?
推荐答案
您不需要您的来电推迟至$ HTTP，因为它已经返回的承诺。
You don't need to defer your call to $http because it already returns a promise.
就返回
return $http.get("/Feed/GetTrenings", { params: { treningId: data } });
那么任何调用你的函数可以这样做：
then anything that calls your function can do:
getTrenings(myData).then(function(data) { do something }).fail(function() { error });
