它指出，问题是与CORS头不发回的情况下，错误的React。只是一个API问题，而不是rtk查询实现错误。

你为什么不这样试试

import { createApi, fetchBaseQuery } from "@reduxjs/toolkit/query/react";
import { logout } from "./slice/authSlice";

const baseQuery = fetchBaseQuery({
// eslint-disable-next-line no-undef
baseUrl: `${process.env.REACT_APP_BASE_URL}`,
credentials: 'include',
prepareHeaders: (headers, { getState }) => {
    const token = getState().auth.token
    if (token) {
        headers. Set("authorization", `Bearer ${token}`)
    }
    return headers
 }
})

const baseQueryWithReauth = async (args, api, extraOptions) => {
let result = await baseQuery(args, api, extraOptions)

if (result?.error?.status === 403) {
    api.dispatch(logout())
    //console.log('sending refresh token')
    // send refresh token to get new access token 
   /* const refreshResult = await baseQuery('/refresh', api, extraOptions)
    console.log(refreshResult)
    if (refreshResult?.data) {
        const user = api.getState().auth.user
        // store the new token 
        api.dispatch(setCredentials({ ...refreshResult.data, user }))
        // retry the original query with new access token 
        result = await baseQuery(args, api, extraOptions)
    } else {
        api.dispatch(logout())
    }*/
}

  return result
}

export const api = createApi({
 baseQuery: baseQueryWithReauth,
 reducePath: "adminApi",
 tagTypes: ["User", "Auth", "Customers"],
 endpoints: (build) => ({

    //auth
    login: build. Mutation({
        query: (body) => ({
            url: `users/login`,
            method: 'POST',
            body,
        }),
        invalidatesTags: ['User'],
    }),
    logout: build. Mutation({
        query: (body) => ({
            url: `users/logout`,
            method: 'PUT',
            body,
        }),
        invalidatesTags: ['User'],
    }),
    register: build. Mutation({
        query: (body) => ({
            url: `users/register`,
            method: 'POST',
            body,
        }),
        invalidatesTags: ['User'],
    }),
 })
})

export const {  useLogoutMutation, useLoginMutation, useRegisterMutation } = api;

注意我选择错误result?.error?.status === 403的方式
我希望这能帮上忙。
