Angular 2 http.get

标签: angular http-get

我在Angular 2中执行以下操作并获得运行时异常:

http.get('http://localhost/MyCart/Home/GetProducts').subscribe(result => {
    this.categories = result.json().Data as any[];
    this.LoadDictionary();
    window.console.log(this.categories);
});

这是正确的语法吗?我究竟做错了什么?如果我删除http.get,应用程序就可以了。

修改

错误如下。请记住,我正在使用Angular的.NET Core模板。
