豆瓣API接口開發，結合angularJS來做，感覺爽歪歪！

第一次做還是先說下API 是什么鬼？

API ： application program interface 應用程序編程接口：

有那些常見的API：

webAPI : 通過WEB方式提供結構叫 WEBAOPI ;

API ： 所有有輸入有輸出的東西都可以稱之為API  --- 都是函數；

例如：Math.random()  --- api

 

例如：

豆瓣API 開發平台：

https://developers.douban.com/wiki/?title=guide

 

豆瓣API V2 (測試版)：

https://developers.douban.com/wiki/?title=api_v2

會看到：

 

這些都是豆瓣提供的一些常用的API接口：

找到對應的，例如：電影API V2 進去：

例如：找一個正在上映的接口：

點擊進去就可以看到：

正在上映：
Resources URI
/v2/movie/in_theaters

那么對應的“正在上映”的API地址就是：

http://api.douban.com/v2/movie/in_theaters

訪問就可以看到效果；

 

對應API 接口的一些參數：

 

簡單使用：

例如：start : 表示從那條開始，可以用來做翻頁；

例如：count 表示多少條：

http://api.douban.com/v2/movie/in_theaters?count=2 

 

返回的內容是這樣的：

 

 

這樣看很難看明白：可以借助一些工具：

例如：google的一個插件：

 

 

或者360瀏覽器的：

 

 

使用之后查看后的效果就會好一些；

 

 如何結合angularJS去處理數據？

例如請求回來的數據是這樣的：

 使用angularJS ：

<script type='text/javascript'>
var myApp = angular.module('myApp',[]);
myApp.controller('myAppController',['$scope',function($scope){
    $scope.subjects = date['subjects'];
}]);
})(angular);
</script>

頁面循環遍歷使用 angularJS的語法：

<div ng-app="myAPp" ng-controller="myAppController">
    <div class="media" ng-repeat="item in subjects track by $index">
      <div class="media-left">
        <a href="#">
          <img class="media-object" ng-src="{{item.images.small}}" alt="{{item.title}}">
        </a>
      </div>
      <div class="media-body">
        <h4 class="media-heading">{{item.title}}</h4>
        <p>劇情：{{item.genres.join('、')}}</p>
        <p>演員：<span ng-repeat="atc in item.casts track by $index">{{atc.name}}<span ng-if="!$last">、</span></span></p>
      </div>
    </div>
</div>

頁面效果：

 

 這個只是用 angularJS 結合 豆瓣API 開發的一個小例子。如有雷同，純屬偶然；
