express 重定向

If you've created a site using [Node.js][], there's a great chance you've used the Express framework.  Express has turned into a massive project and for good reason:  it's loaded with useful functionality, an easy API, and massive community support.  On of my recent projects was using Express and I loved it!

如果您使用[Node.js][]创建了一个站点，那么您很有可能会使用Express框架。 Express已变成一个庞大的项目，这有充分的理由：它加载了有用的功能，简单的API和庞大的社区支持。 在我最近的项目中，有一个使用Express，我喜欢它！

One problem I recently needed to solve was creating a 301 redirect from an old staging domain to the new production domain.  Here's how you can create that 301 redirect with Express:

我最近需要解决的一个问题是创建一个从旧暂存域到新生产域的301重定向。 使用Express创建301重定向的方法如下：

app.use(function forceLiveDomain(req, res, next) {
      // Don't allow user to hit Heroku now that we have a domain
      var host = req.get('Host');
      if (host === 'serviceworker-cookbook.herokuapp.com') {
        return res.redirect(301, 'https://serviceworke.rs/' + req.originalUrl);
      }
      return next();
    });

Surprisingly the redirect code is the first argument to `redirect` instead of the URL.  It's important to call `next()` at the end of the function or a non-match will make your app hang!

令人惊讶的是重定向代码是第一个参数`redirect` ，而不是URL。 在函数末尾调用`next()`很重要，否则不匹配会使您的应用挂起！
