angularjs – 将ajax请求转换为angular $http

2023年5月15日 228次阅读

我正在学习如何使用角度,而且我并不熟悉向api发出请求.我正在尝试使用
http://api.football-data.org/index.我想从我的角度工厂获得的json数据是
http://api.football-data.org/v1/competitions/426/leagueTable.现在我在控制台中出错了

‘angular.js:13920 TypeError: Cannot read property ‘getLeagueData’ of undefined at new …’

我的CLI显示我正在加载我的所有脚本文件,并且在尝试引入工厂并创建getLeagueData函数之前测试了我的控制器并且它正在工作所以我知道我的问题是在创建基本控制器之后.我认为这可能与我需要我收到的身份验证令牌的标题有关,但我不确定我是否没有正确添加它.这是我的代码

模

var app = angular.module('bplApp',[]);

调节器

app.controller('tableController', ['$scope', 'footballData', function($scope, footballData){
var self = this;

self.test = 'is working';
self.leagueStats = [];

footballData.getLeagueData().then(function(data){
    self.leagueStats = data;
    console.log(self.leagueStats);
  })
}])

厂

app.factory('footballData', [function($http){
      return {
        getLeagueData: function(){
            return $http({
              method: 'GET',
              url: 'http://api.football-data.org/v1/competitions/426/leagueTable',
              headers:{
                  'X-Auth-Token': '3e629af30fce46edaa6ead20e007a276'
              }
            })
        }  
      }
}])

api显示使用它的原始ajax代码示例如下所示

$.ajax({
  headers: { 'X-Auth-Token': 'YOUR_API_TOKEN' },
  url: 'http://api.football-data.org/v1/fixtures?timeFrame=n1',
  dataType: 'json',
  type: 'GET',
}).done(function(response) {
  // do something with the response, e.g. isolate the id of a linked     resource        
  var regex = /.*?(\d+)$/; // the ? makes the first part non-greedy
  var res = regex.exec(response.fixtures[0]._links.awayTeam.href);
  var teamId = res[1];
  console.log(teamId);
});

最佳答案 您在工厂使用了数组符号.要么直接使用它,要么在数组中声明$http：

app.factory('footballData', ["$http", function($http){
      return {
        getLeagueData: function(){
            return $http({
              method: 'GET',
              url: 'http://api.football-data.org/v1/competitions/426/leagueTable',
              headers:{
                  'X-Auth-Token': '3e629af30fce46edaa6ead20e007a276'
              }
            })
        }  
      }
}])

要么

app.factory('footballData', function($http){
      return {
        getLeagueData: function(){
            return $http({
              method: 'GET',
              url: 'http://api.football-data.org/v1/competitions/426/leagueTable',
              headers:{
                  'X-Auth-Token': '3e629af30fce46edaa6ead20e007a276'
              }
            })
        }  
      }
})

选择哪种方法取决于您,有some docs可以帮助您做出决定.
