Express JS：TypeError [ERR_INVALID_ARG_TYPE]：“url”参数必须是字符串类型。收到的型号

Question

我正在通过这个 TUT 在 shopify build-a-shopify-app-with-node-and-react 中制作一个私人应用程序

TUT 使用koa，但我使用的是express。部分是因为我知道 express 并且想看看我是否可以抽象出正在发生的事情并将其应用到不同的上下文中。

当我到达 Authenticate and test your app 时，他们希望有人这样做：

添加您的 ngrok 转发 URL 的 HTTPS 版本和您商店的 指向以下占位符的 URL 并将其加载到浏览器中：

提示

这导致我的错误：

这是我的 server.js：

/* eslint-disable vars-on-top */
require('isomorphic-fetch');
var express = require('express');
var next = require('next');
var ShopifyAuth = require('express-shopify-auth');
var dotenv = require('dotenv');
var session = require('express-session');

dotenv.config();

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

var { SHOPIFY_API_SECRET_KEY, SHOPIFY_API_KEY } = process.env;

app.prepare().then(() => {
  var auth = ShopifyAuth.create({
    appKey: SHOPIFY_API_KEY,
    appSecret: SHOPIFY_API_SECRET_KEY,
    baseUrl: port,
    authPath: '/auth',
    authCallbackPath: '/auth/callback',
    authSuccessUrl: '/success',
    authFailUrl: '/fail',
    scope: ['read_products'],
    shop(req, done) {
      return done(null, req.query.shop);
    },
    onAuth(req, res, shop, accessToken, done) {
      // save auth info to session
      req.session.shopify = { shop, accessToken };
      return done();
    },
  });

  var server = express();

  server.use(
    session({
      secret: SHOPIFY_API_SECRET_KEY,
      resave: false,
      saveUninitialized: true,
    })
  );

  server.use(auth);

  server.get('/success', function(req, res) {
    res.json(req.session.shopify);
  });

  server.get('/fail', function(req, res) {
    res.send('Authentication failed');
  });

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

有人有什么见解吗？

您在 baseurl 属性中传递端口，该属性是一个数字。你应该在那里添加网址。
