问题

我有这段代码：

const app = express();

const accountApp = express();
const publicApp = express();

publicApp.use(express.static(path.join(process.cwd(), "web/dist/public")));
accountApp.use(express.static(path.join(process.cwd(), "web/dist/account")));

app.use(vhost('account.*', accountApp));
app.use(publicApp);

它在本地主机上运行得很完美：http://localhost:3000 显示公共应用程序，http://account.localhost:3000 显示帐户应用程序。

我将其托管在Heroku上，并添加了子域名，如下所示：

并且在Google Domains上配置如下：

当我访问 www.stravamenu.com 时，它显示了公共应用程序，正如应该的那样。但是在 account.stravamenu.com 上，它显示了公共应用程序，而不是帐户应用程序。

问题在于 vhost 吗？还是因为 Heroku 或 Google Domains？

const app = express();

const accountApp = express();
const publicApp = express();

publicApp.use(express.static(path.join(process.cwd(), "web/dist/public")));
accountApp.use(express.static(path.join(process.cwd(), "web/dist/account")));

app.use(vhost('account.*', accountApp));
app.use(publicApp);

答案1

得分: 0

app.use(vhost('account.*.*', accountApp));
app.use(vhost("www.*.*", publicApp));

由于某种原因，'account.' 与 'account..' 不相同。所以 'account.' 将在本地主机上运行。如果您想将 'account..' 更改为 'account.*'，我建议添加一个检查是否处于开发模式的语句：

const isProd = proccess.env.PROD;

if(isProd) {
    app.use(vhost('account.*.*', accountApp));
    app.use(vhost("www.*.*", publicApp));
} else {
   app.use(vhost('account.*', accountApp));
   app.use(publicApp); // 如果您不想在本地主机之前添加 www
}

不要忘记在Heroku和Google Domains中设置子域名，并不要忘记在Heroku中添加环境变量。

**Solution:**

app.use(vhost('account..', accountApp));
app.use(vhost("www..", publicApp));

For some reason `account.*` is not the same as `account.*.*`. So `account.*` will work on localhost. If you want to change `account.*.*` with `account.*` I recommend adding a statement that checks if you're in dev mode:

const isProd = proccess.env.PROD;

if(isProd) {
app.use(vhost('account..', accountApp));
app.use(vhost("www..", publicApp));
} else {
app.use(vhost('account.*', accountApp));
app.use(publicApp); // if you don't want to add www before localhost
}

Don't forget to set up subdomains in heroku and google domains, and don't forget to add env variable in heroku
