用React和Node问题建立合作Ap

Question

我正在跟踪Shopify应用程序开发方法--由shopify提供，但是我的本地主机一直有一个错误:外部服务器错误，终端中的原因是‘上下文没有被正确初始化。请调用.initialize()方法来设置您的应用上下文对象。’但不知道如何在下面的server.js文件中这样做；

require('isomorphic-fetch');
const dotenv = require('dotenv');
const Koa = require('koa');
const next = require('next');
const { default: createShopifyAuth } = require('@shopify/koa-shopify-auth');
const { verifyRequest } = require('@shopify/koa-shopify-auth');
const session = require('koa-session');

dotenv.config();

const port = parseInt(process.env.PORT, 10) || 3000;
const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();

const { SHOPIFY_API_SECRET_KEY, SHOPIFY_API_KEY } = process.env;

app.prepare().then(() => {
  const server = new Koa();
  server.use(session({ secure: true, sameSite: 'none' }, server));
  server.keys = [SHOPIFY_API_SECRET_KEY];

  server.use(
    createShopifyAuth({
      apiKey: SHOPIFY_API_KEY,
      secret: SHOPIFY_API_SECRET_KEY,
      scopes: [
        'read_products',
        'write_products',
        'read_script_tags',
        'write_script_tags'
      ],
      afterAuth(ctx){
        const { shop, accessToken } = ctx.session;

        ctx.redirect('/');
      },
    }),
  );

  server.use(verifyRequest());
  server.use(async (ctx) => {
    await handle(ctx.req, ctx.res);
    ctx.respond = false;
    ctx.res.statusCode = 200;
    return
  });

  server.listen(port, () => {
    console.log(`> Ready on http://localhost:${port}`);
  });
});

有些东西已经更新了Shopify的应用程序开发(取决于您的软件包版本)。

现在您需要插入一个Shopify上下文。

// ...

const { default: Shopify, ApiVersion } = require('@shopify/shopify-api');

// ...

Shopify.Context.initialize({
  API_KEY: process.env.SHOPIFY_API_KEY,
  API_SECRET_KEY: process.env.SHOPIFY_API_SECRET,
  SCOPES: process.env.SHOPIFY_API_SCOPES.split(","),
  HOST_NAME: process.env.SHOPIFY_APP_URL.replace(/https:\/\//, ""),
  API_VERSION: ApiVersion.October20,
  IS_EMBEDDED_APP: true,
  SESSION_STORAGE: new Shopify.Session.MemorySessionStorage(),
});

// ...

当然，您还需要对server.js文件进行其他小的更新。

要获得更高的精度，您可以直接查看官方的Shopify React/Node app dev tuto源代码：https://github.com/Shopify/shopify-app-node/blob/tutorial_listen_for_store_events/server.js
