Question

我正在使用react-apollo和apollo-client开发nextJS。我正在使用apollo-cache-persist来保存我的数据。但是当我刷新页面时，数据会丢失。

我尝试了此处提供的解决方案，但遗憾的是没有用。

import React from "react";
import Head from "next/head";
import App, { Container } from "next/app";
import { ApolloClient } from "apollo-client";
import {ApolloProvider} from "react-apollo";
import { InMemoryCache } from "apollo-cache-inmemory";
import { createHttpLink } from "apollo-link-http";
import { withClientState } from "apollo-link-state";
import fetch from "node-fetch";
import { resolvers, defaults } from "../Container/resolvers";
import { ApolloLink } from "apollo-link";

const cache = new InMemoryCache();

const stateLink = withClientState({
  cache,
  defaults,
  resolvers
});

const httpLink = new createHttpLink({
  fetch,
  uri: "http://localhost:4444/",
  headers: {
    "Content-Type": "application/json"
  }
});

export const client = new ApolloClient({
  link: ApolloLink.from([stateLink, httpLink]),
  cache
});
export default class MyApp extends App {
  static async getInitialProps({ Component, ctx }) {
    return {
      pageProps: {
        // Call page-level getInitialProps
        ...(Component.getInitialProps
          ? await Component.getInitialProps(ctx)
          : {})
      }
    };
  }
  async ComponentWillMount() {
    await persistCache({
      cache
    });
  }
  render() {
    const { Component, pageProps, store } = this.props;
    return (
      <ApolloProvider client={client}>
        <Container>
            <Head>
              <title>HELLO WORLD</title>
            </Head>
            <Component {...pageProps} />
        </Container>
      </ApolloProvider>
    );
  }
}

我希望缓存能够保留，但是重新加载时缓存什么也不会返回。

缓存在刷新后不持久
