Redux RTK 查询:getDefaultMiddleware 不是一个函数

getDefaultMiddleware
来自哪里?我正在阅读
文档
,它似乎神奇地出现在配置存储中。虽然这很棒,但它并没有进入我的商店,而且......因为这个函数没有导入路径,而且我不知道如何解决这个问题,所以我可以使用一些指导。
rtk 版本:
“@reduxjs/toolkit”:“^1.6.1”,
tldr;
getDefaultMiddleware()
在我的商店中不存在 + 我还没有在文档中找到关于它的任何有用的东西。
这是我得到的错误:
这是我的
store.ts
import { Action, configureStore, ThunkAction } from '@reduxjs/toolkit';
import { setupListeners } from '@reduxjs/toolkit/query';
import { myApi } from './services/api';
import authorReducer from './slices/authorSlice';
import transcriptReducer from './slices/transcriptSlice';
export const store = configureStore({
reducer: {
[myApi.reducerPath]: myApi.reducer,
middleware: (getDefaultMiddleware) =>
// "This expression is not callable."
getDefaultMiddleware().concat(myApi.middleware),
author: authorReducer,
transcript: transcriptReducer,
},
});
setupListeners(store.dispatch);
// Infer the `RootState` and `AppDispatch` types from the store itself
export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;
export type AppThunk<ReturnType = void> = ThunkAction<
ReturnType,
RootState,
unknown,
Action<string>
>;
这是我的
api.ts
import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';
const apiEndpoint ='http://localhost:5000';
export const myApi = createApi({
reducerPath: 'myApi',
baseQuery: fetchBaseQuery({ baseUrl: apiEndpoint }),
endpoints: builder => ({
getFileById: builder.query<any, { id: string; fileId: string }>({
query: arg => {
const { id, fileId } = arg;
return `/some/endpoint/with/two/${id}/pathvariables/${fileId}`;
},
}),
}),
});
// RTK Query will automatically generate hooks for each endpoint query
export const { useGetFileByIdQuery } = myApi;

答案:
我的中间件
在
reducer: { ... } 内定义。我需要将其
移出
该 Reducer 对象。问题解决了。
export const store = configureStore({
reducer: {
[myApi.reducerPath]: myApi.reducer,
author: authorReducer,
transcript: transcriptReducer,
},
middleware: getDefaultMiddleware =>
getDefaultMiddleware().concat(myApi.middleware),
});

不要忘记像这样调用 getDefaultMiddleware getDefaultMiddleware() 然后说 .concat(myApi.middleware) 否则你会得到同样的错误。
export const store = configureStore({
reducer: {
[myApi.reducerPath]: myApi.reducer,
author: authorReducer,
transcript: transcriptReducer,
},
middleware: getDefaultMiddleware =>
getDefaultMiddleware().concat(myApi.middleware),
});

我使用 Redux 持久化时是这样工作的:
const rootReducer = combineReducers({
user:userSlice,
fetchUsers:fetchUserSlice,
[MyPostApi.reducerPath]:MyPostApi.reducer,
})
const persistConfig = {
key:'zomatostore',
version:1,
storage,
}
const persistedReducer = persistReducer(persistConfig, rootReducer)
export const store = configureStore({
reducer:persistedReducer,
middleware:getDefaultMiddleware => getDefaultMiddleware().concat(MyPostApi.middleware)
});
