Return 来自 NodeJS 服务器的 JSONP AngularJS

Return JSONP from NodeJS server with AngularJS

我正在尝试在我的应用程序上实施 ngInfiniteScroll - Loading Remote Data

Demo 运行良好,我成功获得了 Reddit API,但我的列表无法运行。

我成功命中 200 服务器响应并且可以在开发工具中看到我的数据。这些答案提供了一些帮助 1 & 2 但我仍然不确定该怎么做。


编辑(参见 angular 工厂编辑):

此回调正在运行,$http 将会成功,但我现在得到 Cannot read property 'length' of undefined


Angular工厂:

Reddit.prototype.nextPage = function() {
  if (this.busy) return;
  this.busy = true;

  // Edit - I changed this var from
  // var url = config_api.API_ENDPOINT_LOCAL + "list?after=" + this.after + "?alt=json-in-script&jsonp=JSON_CALLBACK";
  // to
  var url = config_api.API_ENDPOINT_LOCAL + "list?after=" + this.after + "?alt=json-in-script&callback=JSON_CALLBACK";

  $http.jsonp(url)
    .success(function(data) {
      console.log(data);
      var items = data.children;
      for (var i = 0; i < items.length; i++) {
        this.items.push(items[i].data);
      }
      this.after = "t3_" + this.items[this.items.length - 1].id;
      this.busy = false;
    }.bind(this));
  console.log('Reddit.prototype');
};

NodeJS 路线:

app.get('/list', function (req, res) {

  Found.find(function (err, post) {
    if ( err ) {
      res.send( err );
    }
    res.jsonp( post );
  });

});
Reddit.prototype.nextPage = function() {
  if (this.busy) return;
  this.busy = true;

  // Edit - I changed this var from
  // var url = config_api.API_ENDPOINT_LOCAL + "list?after=" + this.after + "?alt=json-in-script&jsonp=JSON_CALLBACK";
  // to
  var url = config_api.API_ENDPOINT_LOCAL + "list?after=" + this.after + "?alt=json-in-script&callback=JSON_CALLBACK";

  $http.jsonp(url)
    .success(function(data) {
      console.log(data);
      var items = data;
      for (var i = 0; i < items.length; i++) {
        this.items.push(items[i]);
      }
      this.after = "t3_" + this.items[this.items.length - 1].id;
      this.busy = false;
    }.bind(this));
  console.log('Reddit.prototype');
};

应该修复它!
