这是我在不同起点和终点之间绘制折线的代码。这很好用。现在我需要将它与我的角度代码集成，后者从我的数据库中获取数据。

  var app = angular.module('myApp', []);
 angular.module('myApp', []).controller('orderCtrl',   function($scope,$http,$interval){


load_userrequest();



function load_userrequest(){
    console.log("in angular user request view");
$http.get('http://localhost:3001/bill').success(function(data){
    console.log(data);
        $scope.users=data;
});
};

});

如何整合这些代码？我想在$ scope.users = data之后包含我的initMap函数。当我这样做时，我得到一个错误，说window.init没有定义

以下转换的AngularJS示例显示了如何从外部端点读取坐标：

angular.module('mapsApp', [])
.controller('MapCtrl', function ($scope,$http) {

  $scope.map = new google.maps.Map(document.getElementById('map_div'), {
    zoom: 3,
    center: {lat: 0, lng: -180},
    mapTypeId: google.maps.MapTypeId.TERRAIN
  });


  $http.get('https://gist.githubusercontent.com/vgrem/61352c9edea7bec8d1e0/raw/20673c41c76cfffdb827d65a363b8ba4b0fc15e7/flightPlanCoordinates.json')
  .success(function(data) {

    data.forEach(function(coords){
  
      var flightPath = new google.maps.Polyline({
         path: coords,
         geodesic: true,
         strokeColor: '#FF0000',
         strokeOpacity: 1.0,
         strokeWeight: 2
      });
      flightPath.setMap($scope.map);
    });
      
  });

});

 html, body {
    height: 100%;
    margin: 0;
    padding: 0;
  }
  #map_div {
    height: 600px;
  }
