 - `pollInterval`: auto update using polling (which means refetching every `x` ms). Default: `undefined`, `0` - stop polling.
 - `update(data) {return ...}` to customize the value that is set in the vue property, for example if the field names don't match.

 - `error(error, vm, key, type, options)` is a hook called when there are errors. `error` is an Apollo error object with either a `graphQLErrors` property or a `networkError` property. `vm` is the related component instance. `key` is the smart query key. `type` is either `'query'` or `'subscription'`. `options` is the final `watchQuery` options object.
 - `loadingKey` will update the component data property you pass as the value. You should initialize this property to `0` in the component `data()` hook. When the query is loading, this property will be incremented by 1; when it is no longer loading, it will be decremented by 1. That way, the property can represent a counter of currently loading queries.
 - `watchLoading(isLoading, countModifier)` is a hook called when the loading state of the query changes. The `countModifier` parameter is either equal to `1` when the query is loading, or `-1` when the query is no longer loading.

 - `loadingKey` 将更新你传递的值所对应的组件数据属性。你应该在组件的 `data()` 钩子中将此属性初始化为 `0` 。当查询正在加载时，此属性将增加 1；当不再加载时，它将减去 1。这样，该属性可以表示当前正在加载中的查询的计数器。
