json - 从 Flask 后端获取对 Angular 的 JSON 响应

Question

我想从 Flask 后端获取到 Angular 应用程序的 JSON 响应，但找不到错误所在。返回的 JSON 响应是:

{
  "phones": [
    {
    "age": 0, 
    "name": "Nexus S", 
    "snippet": "Fast just got faster with Nexus S."
    }, 
    {
    "age": 1, 
    "name": "Motorola XOOM with Wi-Fi", 
    "snippet": "The Next, Next Generation tablet."
    }, 
    {
    "age": 2, 
    "name": "MOTOROLA XOOM", 
    "snippet": "The Next, Next Generation tablet."
    }
  ]
}

这是 Controller :

function Phones($scope, $http){
$http.get('127.0.0.1:5000/phones').success(function(data){
$scope.phns = data.phones;
    console.log("I'm called");
});
}

当我像这样将 JSON 对象传递给 Controller ​​时，这有效:

$scope.phones = [
{"name": "Nexus S",
 "snippet": "Fast just got faster with Nexus S.",
 "age": 0},
{"name": "Motorola XOOM with Wi-Fi",
 "snippet": "The Next, Next Generation tablet.",
 "age": 1},
{"name": "MOTOROLA XOOM",
 "snippet": "The Next, Next Generation tablet.",
 "age": 2}
];

当我尝试获取 data.phones 之类的数据时，它也不起作用。我确定 Controller 会被调用，但 get 函数不会以某种方式获取数据。

将“http”添加到 127.0.0.1:5000/phones 应该可以解决问题。
