我在Heroku中設(shè)置了一個(gè)自定義域，效果很好。我可以使用我的應(yīng)用名稱和自定義域來訪問我的網(wǎng)站。我可以使用標(biāo)準(zhǔn)的Heroku URL訪問路由，但不能使用自定義域。例如：作品：https://{myappname}.herokuapp.comhttps://{myappname}.herokuapp.com/callbackhttps://{customdomain}.com不起作用：https://{customdomain}.com/callback服務(wù)器配置：const express = require("express");const path = require("path");;const callback = require("./callback");const app = express();// Body parser middlewareapp.use(bodyParser.urlencoded({ extended: false }));app.use(bodyParser.json());// Serve static assets if in production if (process.env.NODE_ENV === "production") {  app.use("/callback", callback);// Set static folder  app.use(express.static("client/build"));  app.get("*", (req, res) => {   res.sendFile(path.resolve(__dirname, "client", "build", "index.html")); });}// Init server/portconst port = process.env.PORT || 5000;app.listen(port, () => console.log(`Server running on port ${port}`));
