显示JSON数据在角应用 [英] Displaying json data in an Angular App
问题描述
我想从一个JSON文件解析数据,并在我的角度应用程序中显示,但对于一些奇怪的原因的看法不会显示数据(INTE preT我的前妻pressions),我想这可能是我的控制器,但它看起来不错。任何帮助将是解决这一pciated AP $ P $,谢谢。
下面是code为我的HTTP服务:
app.factory('信息',['$ HTTP',函数($ HTTP){
返回
$http.get('https://api.flickr.com/services/feeds/photos_public.gne?&format=json&callback=JSON_CALLBACK')
.success(功能(数据){
返回的数据;
})
.error(功能(错误){
返回ERR;
});
}]);
下面是我的控制器:
app.controller(HomeController中',['$范围','信息',
功能($范围){
info.success(功能(数据){
$ scope.datar =数据;
});
}]);
这是我的看法:
< DIV CLASS =主>
< DIV CLASS =容器>
< DIV CLASS =照片>
< DIV NG控制器=HomeController的NG重复=数据DATAR>
< P1> {{data.age}}< / P1>
< P1> {{name.modified}}< / P1>
< / DIV>
< / DIV>
< / DIV>
< / DIV>
既然要查询JSONP端点你需要使用的 $ http.jsonp 方法。而且非常重要:把 $ http.jsonp
的相同行收益
,不然自动插入分号把它变成的回报;
基本返回未定义
。
app.factory('信息',['$ HTTP',函数($ HTTP){
返回$http.jsonp('https://api.flickr.com/services/feeds/photos_public.gne?&format=json&jsoncallback=JSON_CALLBACK')
。然后(功能(响应){
返回response.data;
});
}]);
请注意参数名 jsoncallback
,不只是回调。
在您的控制器也应该使用然后
,而不是成功的(它的德precated):
app.controller(HomeController中',['$范围','信息',函数($范围,资讯){
info.then(功能(数据){
$ scope.datar =数据;
});
}]);

I am trying to parse data from a json file and display it in my angular application, but for some odd reason the view wouldn't show the data(intepret my expressions), I thought it might be my controller, but it looks fine. Any help would be appreciated in solving this, thanks.
Below is the code for my Http Service:
app.factory('info', ['$http', function($http){
return
$http.get('https://api.flickr.com/services/feeds/photos_public.gne?&format=json&callback=JSON_CALLBACK')
.success(function(data){
return data;
})
.error(function(err){
return err;
});
}]);
Here is my controller:
app.controller('HomeController', ['$scope','info',
function($scope) {
info.success(function(data){
$scope.datar = data;
});
}]);
And this is my view:
<div class="main" >
<div class="container" >
<div class="photo" >
<div ng-controller="HomeController" ng-repeat="data in datar">
<p1>{{data.age}}</p1>
<p1>{{name.modified}}</p1>
</div>
</div>
</div>
</div>
Since you are querying JSONP endpoint you need to use $http.jsonp method. And very important: put $http.jsonp
on the same line after return
, otherwise automatic semicolon insertion turns it into return;
basically returning undefined
.
app.factory('info', ['$http', function($http) {
return $http.jsonp('https://api.flickr.com/services/feeds/photos_public.gne?&format=json&jsoncallback=JSON_CALLBACK')
.then(function(response) {
return response.data;
});
}]);
Note parameter name jsoncallback
, not just "callback".
After that your controller should also use then
instead of success (it's deprecated):
app.controller('HomeController', ['$scope', 'info', function($scope, info) {
info.then(function(data) {
$scope.datar = data;
});
}]);
