这个问题可以通过在Apollo Client的links中添加一个错误链接来解决。当刷新token过期时，错误链接将被调用，并且我们可以使用它来执行所需的操作。以下是解决此问题的示例代码：

import { ApolloLink, Observable } from "apollo-link";
import { onError } from "apollo-link-error";
import { setContext } from "apollo-link-context";
import { HttpLink } from "apollo-link-http";
import { withClientState } from "apollo-link-state";
import { InMemoryCache } from "apollo-cache-inmemory";
import { ApolloClient } from "apollo-client";
import Token from "./utils/token";

const httpLink = new HttpLink({
  uri: "graphql_server_url"
});

const authLink = setContext(async (req, { headers }) => {
  const token = await Token.load();

  return {
    headers: {
      ...headers,
      authorization: token ? `Bearer ${token}` : ""
    }
  };
});

const errorLink = onError(({ response, graphQLErrors, networkError }) => {
  if (graphQLErrors && graphQLErrors.some(isUnauthorizedError)) {
    Token.delete(); // 清除旧令牌
    window.location.replace("/login"); // 重定向到登录页
  }
});

const defaultOptions = {
  watchQuery: {
    fetchPolicy: "cache-and-network",
    errorPolicy: "all"
  },
  query: {
    fetchPolicy: "cache-and-network",
    errorPolicy: "all"
  }
};

const cache = new InMemoryCache();

const stateLink = withClientState({cache});

const links = ApolloLink.from([
  stateLink,
  errorLink,
  authLink,
  httpLink
]);

const apolloClient = new ApolloClient({
  link: links,
  cache: cache,
  defaultOptions: defaultOptions
});

function isUnauthorizedError(error) {
  const { extensions } = error;
  const { code } = extensions || {};

  return code === "UNAUTHENTICATED";
}

export default apolloClient;

在代码中，我们添加了一个错误链接（errorLink），该链接将在遇到GraphQL错误时执行。具体而言，我们检查GraphQLErrors中是否有UNAUTHENTICATED代码的错误，如果是，则清除旧令牌并重定向到登录页面。当links中的其余链接（authLink和httpLink）使用时，我们确保在请求头中包含有效的令牌。最后，我们导出一个初始化的Apollo客户端实例（
