Angular app http调用自定义服务失败

我正在制作一个有点角色的应用程序,以显示有关英超联赛的信息。我想提供一个服务来处理http调用,因为我在页面上做了几次,我不想重复所有事情。这是我的table.js TableController,用于构建联赛表/

(function(){

angular
.module("eplApp")
.controller("tableCtrl", TableController);

TableController.inject = ['httpService'];

function TableController(service){
  var apiUrl = "http://api.football-data.org/v1/soccerseasons/426/leagueTable";

  service.getListFromUrl(apiUrl).then(function(data){
var vm.this;
vm.data = response.data;
});
}
})();

这是我为运行http请求而生成的服务,service.js:

(function(){

angular
.module("eplApp")
.factory("httpService", httpService);

httpService.inject = ['$http'];

function httpService($http){
var apiKey = '971acba677654cdb919a7ccebd5621e2';
var vm = this;
vm.data = [];

$http({
  headers: { 'X-Auth-Token': apiKey },
  method: "GET",
  url: apiUrl
}).then(function(response) {
  vm.data = response.data;
  return vm.data;
});
}
})();

当我运行它时,我收到以下错误:

Error: [$injector:unpr] http://errors.angularjs.org/1.5.8/$injector/unpr?p0=serviceProvider%20%3C-%20service%20%3C-%20tableCtrl

我在哪里错了?

检查你使用的控制器,控制器功能参数是httpService,你用的是HttpService。请查一下,它区分大小写。

尝试更改您的服务:

(function(){

    angular
    .module("eplApp")
    .factory("httpService", httpService);

    httpService.$inject = ['$http'];

    function httpService($http){
     return {
       getListFromURL : getListFromURL
     }

     function getListFromURL(apiUrl){
      var apiKey = '971acba677654cdb919a7ccebd5621e2';
      var vm = this;
      vm.data = [];

      return $http({
       headers: { 'X-Auth-Token': apiKey },
       method: "GET",
       url: apiUrl
      }).then(function(response) {
        vm.data = response.data;
        return vm.data;
      });
    }
})();

然后在控制器中调用这个函数:

TableController.$inject = ['httpService'];

function TableController(service){
  var apiUrl = "http://api.footballdata.org/v1/soccerseasons/426/leagueTable";

  service.getListFromURL(apiUrl).then(function(data){
    //data here is vm.data
  });
}

希望这有帮助!
