Redux RTK 查询 invalidatesTags 突变后未调用

Question

我一直在试图找出为什么标签失效不起作用并添加了一些日志记录。in工作正常，但providesTagsin从未被调用。可能出了什么问题？getMeinvalidatesTagslogin

我有一个像这样的 redux RTK 查询 API：

const baseQuery = fetchBaseQuery({
  baseUrl: baseUrl,
  prepareHeaders: (headers, { getState }) => {
    const token = getState().auth.token
    if (token) {
      headers.set('authorization', `Bearer ${token}`)
    }
    return headers
  },
})

export const api = createApi({
  baseQuery: baseQuery,
  tagTypes: ['User'],
  endpoints: build => ({
    login: build.mutation({
      query: code => ({
        url: `auth/login/?code=${code}`,
        method: 'POST',
      }),
      invalidatesTags: (result, error, arg) => {
        console.log('auth/login', result, error, arg)
        return ['User']
      },
    }),
    getMe: build.query({
      query: () => 'auth/me',
      providesTags: result => {
        console.log('auth/me', result)
        return ['User']
      },
    }),
  }),
})

export const { useLoginMutation, useGetMeQuery } = api

login当从回调加载页面时在组件安装时调用，如下所示：

const CallbackComponent = () => {
  const location = useLocation()
  const [login, { isUninitialized, isLoading, isError, data, error }] = useLoginMutation()

  useEffect(() => {
    if (isUninitialized) login(getCode(location))
  })
  ...
}

getMe在这样的组件中使用：

const Header = () => {
  const isAuthenticated = useIsAuthenticated()
  const {
    data: user,
    isError,
    error,
  } = useGetMeQuery(null, {
    skip: !isAuthenticated,
  })

  if (isError) return <span>{JSON.stringify(error)}</span>

  return (
    <nav className="header">
      {user ? <CharacterList characters={user.characters} /> : null}
      {!user || user.characters.length === 0 ? <Login /> : null}
    </nav>
  )
}

事实证明问题并不在这些地方。我还没有将 api 中间件添加到我的商店中。

export const store = configureStore({
  reducer: rootReducer,
  middleware: getDefaultMiddleware =>
    getDefaultMiddleware().concat(api.middleware),
})
