　　AngularJS $http是一个从Web服务器读取数据的核心服务。

　　$http.get(url)是一个用来从服务器读取数据的函数。

<div ng-app="myApp" ng-controller="customersCtrl"> 

<ul>
  <li ng-repeat="x in names">
    {{ x.Name + ‘, ‘ + x.Country }}
  </li>
</ul>

</div>

<script>
var app = angular.module(‘myApp‘, []);
app.controller(‘customersCtrl‘, function($scope, $http) {
    $http.get("http://example.php")
    .success(function(response) {$scope.names = response.records;});
});
</script>
