Question

我正在使用AngularJS，我想动态获取价格的价值，我的意思是从url json数据中获取它。这可能！[/ p>

这是 url json ：url

这是我的控制器：

angular.module("myApp",['zingchart-angularjs']).controller('MainController', ['$scope', '$http', function($scope, $http) {

  $scope.cities =[{
    "name": "city A",
        "elements": [{
          "id": "c01",
          "name": "name1",
          "price": "15",//I want to get this price from the url json: [url][1]. Get  it from the value of prix_diesel attribute 
          "qte": "10" //I want to get this price from the url json. Get it from the value of prix_essence attribute 
        }, {
          "id": "c02",
          "name": "name2",
          "price": "18",
          "qte": "11"
        }, {
          "id": "c03",
          "name": "name3",
          "price": "11",
          "qte": "14"
        }],
        "subsities": [{
          "name": "sub A1",
          "elements": [{
            "id": "sub01",

            "price": "1",
            "qte": "14"
          }, {
            "id": "sub02",
            "name": "nameSub2",
            "price": "8",
            "qte": "13"
          }, {
            "id": "sub03",
            "name": "nameSub3",
            "price": "1",
            "qte": "14"
          }]
        }, {
          "name": "sub A2",
          "elements": [{
            "id": "ssub01",
            "name": "nameSsub1",
            "price": "1",
            "qte": "7"
          }, {
            "id": "ssub02",
            "name": "nameSsub2",
            "price": "8",
            "qte": "1"
          }, {
            "id": "ssub03",
            "name": "nameSsub3",
            "price": "4",
            "qte": "19"
          }]
        }, {
          "name": "sub A3",
          "elements": [{
            "id": "sssub01",
            "name": "nameSssub1",
            "price": "1",
            "qte": "11"
          }, {
            "id": "sssub02",
            "name": "nameSssub2",
            "price": "2",
            "qte": "15"
          }, {
            "id": "sssub03",
            "name": "nameSssub3",
            "price": "1",
            "qte": "15"
          }]
        }]
      }, {
        "name": "city B",
        "elements": [{
          "id": "cc01",
          "name": "name11",
          "price": "10",

          "id": "cc02",

          "price": "14",

        }, {
          "id": "cc03",
          "name": "name33",
          "price": "11",
          "qte": "18"
        }]
      }, {
        "name": "city C",
        "elements": [{
          "id": "ccc01",
          "name": "name111",
          "price": "19",
          "qte": "12"
        }, {
          "id": "ccc02",
          "name": "name222",
          "price": "18",
          "qte": "17"
        }, {
          "id": "ccc03",
          "name": "name333",
          "price": "10",
          "qte": "5"
        }]
      }]

  $scope.extractSubsities = function(itemSelected) {
    if(itemSelected && itemSelected.elements){
        $scope.data = itemSelected.elements;
    }

  }

  $http.jsonp("http://total.smarteez.eu/submit/?station=101507")
  .then(function(data) {
      if($scope.cities && $scope.cities[0] && $scope.cities[0].elements && $scope.cities[0].elements[0]){
      $scope.cities[0].elements[0].price = data.data.prix.prix_diesel;
        $scope.cities[0].elements[0].qte = data.data.prix.prix_essence;
      }
    });

 }]);

我在我的plunkr中设置了它：plunker

备注：total.smarteez.eu不是我的服务器

你能帮我加载网址json中的数据吗？

更新：

当我运行我的代码时，浏览器启动了一个错误，如：

未捕获的SyntaxError：意外的令牌？station = 101507：1

编辑：

不，这不是一个重复的问题，因为我问如何从不在我的服务器中的URL json获取数据我认为我需要类似跨域请求的东西。

Answer 1

我试图使用角度服务来检索信息，接下来我在Chrome控制台中获得的信息是：

XMLHttpRequest cannot load http://total.smarteez.eu/submit/?station=101507. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://<<MYIPADDRESS>>' is therefore not allowed access. The response had HTTP status code 401.

这意味着smarteez服务器无法使用CORS，我的意思是，它不允许外部连接检索数据......

你应该在smarteez服务器中启用CORS ....但是你提到它不是你的

如果我是你，我会做什么，将内容加载到带有file_get_contents()函数的PHP变量中，然后将其转换为JSON，最后将其返回到我的角度控制器< / p>
