48d-数据标签

[type: 'student'] 只要符合任意标签，就全部失效，范围太大了，设置id，更加精准

tagTypes: ['student'], 用来指定Api中的标签类型

providesTags: (result, error, id) => [{type: 'student', id}] 设置 添加标签

invalidatesTags: [{type: 'student', id: 'LIST'}] 设置 指定标签失效

    reducerPath: 'studentApi', 
    baseQuery: fetchBaseQuery({
        baseUrl: "http://localhost:1337/api/"
    }),
