React 的 reduxjs/toolkit 在 typescript 报错的原因？-灵析社区
ApplePro> 报错：TS2322: Type any is not assignable to type never  const ErrorSlice = createSlice({ name: 'error', initialState: [], reducers: { Publish: (state, action) => { console.log(action) state = [...state, action.payload] }, Consume: () => [], } }) > 调用端 await axios .post(`host`, Params) .then((data: Response) => data.data.Response) .catch((e) => { ErrorState.dispatch(Publish(e.response.data.Error)) }) 我不太明白 `never` 什么意思我给的不是字符么很明显的
你可以的拿捏了需要使用插件自己的数据类型 "PayloadAction"
import { createSlice, PayloadAction } from '@reduxjs/toolkit'
const ErrorSlice = createSlice({
name: 'error',
initialState: "",
reducers: {
Publish: (_, action: PayloadAction) => action.payload,
Consume: () => "",
}
})
