如果我刷新页面，POST不会完成(POST doesn't complete if I refresh page)

 所以对于这个用例，你应该使用工厂而不是服务。 
 
 在大多数使用factory方法的情况下，它实际上应该使用service方法，并成为ES6中的一个class 。 这种情况是例外。 您需要注册一个调用$resouce factory的工厂方法。 
 
 在ES6中（如果用require替换import，大多数是ES5），它应该看起来像这样： 
 
import {app} from '../app';    

feedLoadFactory.$inject = ['$resource'];
feedLoadFactory($resource) {

    return 
        $resource('http://ajax.googleapis.com/ajax/services/feed/load', 
            {}, {
               fetch: { 
                   method: 'JSONP', 
                   params: {v: '1.0', callback: 'JSON_CALLBACK'} 
               }
        });
}

app.factory('feedLoad', feelLoadFactory);
 
 然后你可以注入它作为feedLoad并使用它作为feedLoad.fetch... 

So for this use case you should be using a factory rather than a service. 
 
In most cases where the factory method is used, it actually should use the service method and be a class in ES6. This case is the exception. You need to register a factory method that calls the $resouce factory. 
 
In ES6 and (and mostly ES5 if you replace import with require) it should look something like this:
 
import {app} from '../app';    

feedLoadFactory.$inject = ['$resource'];
feedLoadFactory($resource) {

    return 
        $resource('http://ajax.googleapis.com/ajax/services/feed/load', 
            {}, {
               fetch: { 
                   method: 'JSONP', 
                   params: {v: '1.0', callback: 'JSON_CALLBACK'} 
               }
        });
}

app.factory('feedLoad', feelLoadFactory);
 
Then you can inject it as feedLoad and use it as feedLoad.fetch...
