fetch API是浏览器原生的，在nodejs中不可用。你看到的错误是由于rtk-query依赖于fetch API。为了使用fetch API，您需要在项目中全局填充它，以便rtk库可以像在浏览器中一样使用它
下面可以看到一种方法

import fetch, { Headers } from 'node-fetch'

globalThis.fetch = fetch;
globalThis.Headers = Headers;

下面是一个如何让rtk-query在nodejs中运行的工作示例
下面列出了在nodejs中实现这一点的关键要素

1. nodejs的polyfill window.fetch
   1.自定义设置将{ fetchFn }传递给fetchBaseQuery
   1.使用不带钩子的rtk查询意味着分散存储并向其分派rtk查询的预定义操作，例如api.endpoints.getCharacters.initiate()
   index.js

import { getCharacters } from "./store/characterService.js";
import fetch, { Headers, Request } from "node-fetch";

globalThis.fetch = fetch;
globalThis.Headers = Headers;
globalThis.Request = Request;

const init = async () => {
  const data = await getCharacters();

  console.log(data);
};

init();

store.js

import redux from "@reduxjs/toolkit";
import reduxQuery from "@reduxjs/toolkit/dist/query/index.js";
import fetch from "node-fetch";

export const api = reduxQuery.createApi({
  reducerPath: "api",
  baseQuery: reduxQuery.fetchBaseQuery({
    baseUrl: "https://rickandmortyapi.com/api",
    fetchFn: (...args) => {
      return fetch(...args);
    },
  }),
  endpoints: (builder) => ({
    getCharacters: builder.query({
      query: () => "/character",
    }),
    getCharacter: builder.query({
      query: (id) => `/character/${id}`,
    }),
  }),
});

let store = null;

const initiateStore = () => {
  store = redux.configureStore({
    reducer: {
      [api.reducerPath]: api.reducer,
    },
    middleware: (getDefaultMiddleware) =>
      getDefaultMiddleware().concat(api.middleware),
  });
};

export const getStore = () => {
  if (!store) {
    console.log(store);
    initiateStore();
  }
  return store;
};

characterService.js

import { getStore, api } from "./store.js";

export const getCharacters = async () => {
  const store = getStore();
  const { data } = await store.dispatch(api.endpoints.getCharacters.initiate());
  return data;
};

export const getCharacter = async (id) => {
  const store = getStore();
  const { data } = await store.dispatch(
    api.endpoints.getCharacter.initiate(id)
  );
  return data;
};

此外，fetchFn是用于配置BaseQuery的属性，queryFn是用于配置单个端点并覆盖该端点的BaseQuery设置的属性
