$cacheFactory

作用：不同的controller之间传递数据。

put(key, value);//添加

get(key);//获取

removeAll();//删除全部

remove('key')//删除某一项

destroy();//完全破坏Cache对象，将其从$cacheFactory集中删除

info();//检索有关特定缓存的信息。

var app = angular.module('test',[])
app.controller('testapp1',function ($scope,$cacheFactory) {
    $scope.cache=$cacheFactory('cache1')
    $scope.cache.put('1','abc');
    $scope.cache.put('2','def');
    $scope.name = $scope.cache.info();
    console.log($scope.name)
})
app.controller('testapp2',function ($scope,$cacheFactory) {
    $scope.cache = $cacheFactory.get('cache1');
    $scope.name= $scope.cache.get('1');
    console.log($scope.name);
})
