RTK-Query 使用需要注意的地方

官方建议 createApi 只应该被调用一次，对于不同领域的 endpoint ，应该使用 injectEndpoints 增加 endpoint ，而不是调用多次 createApi 。

Typically, you should only have one API slice per base URL that your application needs to communicate with. For example, if your site fetches data from both /api/posts and /api/users, you would have a single API slice with /api/ as the base URL, and separate endpoint definitions for posts and users. This allows you to effectively take advantage of automated re-fetching by defining tag relationships across endpoints.
