问题描述

我希望能够创建一个自定义AngularJS服务,当其数据对象为空时发出HTTP获取请求,并在成功时填充该数据对象。

I want to be able to create a custom AngularJS service that makes an HTTP 'Get' request when its data object is empty and populates the data object on success.

下次调用该服务时,我想绕过再次发出HTTP请求的开销,而是返回缓存的数据对象。

The next time a call is made to this service, I would like to bypass the overhead of making the HTTP request again and instead return the cached data object.

这是

推荐答案

Angular的具有。根据文档:

Angular's $http has a cache built in. According to the docs:



布尔值



因此您可以设置在其选项中缓存 true

$http.get(url, { cache: true}).success(...);

或者,如果您喜欢通话的配置类型:

or, if you prefer the config type of call:

$http({ cache: true, url: url, method: 'GET'}).success(...);



缓存对象



您也可以使用缓存工厂:

Cache Object

You can also use a cache factory:

var cache = $cacheFactory('myCache');

$http.get(url, { cache: cache })

您可以使用自己实现(特别是在使用$ resource时特别方便):

You can implement it yourself using $cacheFactory (especially handly when using $resource):

var cache = $cacheFactory('myCache');

var data = cache.get(someKey);

if (!data) {
   $http.get(url).success(function(result) {
      data = result;
      cache.put(someKey, data);
   });
}
