我正在使用bouncy为由两个独立进程（一个 Ghost 博客和一个 Express Web 应用程序）操作的两个站点提供服务。

bouncy(function(req, bounce) {
  if (req.headers.host === 'blogdomain.com' || req.headers.host === 'www.blogdomain.com') {
    // Fwd to blog
    bounce(2368);
  } else {
    // By default, fwd to express webapp
    bounce(8001);
  }
}).listen(80);

问题是请求到达博客并且 Web 应用程序处理好像来自 127.0.0.1。有没有办法保留IP？

编辑：按照提案，loganfsmyth但我只得到了部分期望的行为。

该网络应用程序是一个角度应用程序，我将快速应用程序日志设置为：

app.use(express.logger())

在日志中，客户端的 IP 仅针对某些请求正确显示。其余的仍然是 127.0.0.1。日志样本：

此外，重新加载页面会导致相同的日志条目。我的意思是，第一页日志中出现的文件正确地使用客户端的 IP 加载，而出现在 127.0.0.1 的文件在页面重新加载的情况下是一对一的完全相同的文件。

使用类似 的代理时bouncer，处理此问题的标准方法是使用X-Forwarded-For标头。

bounce(2368, {
    headers: {
        'X-Forwarded-For': req.socket.remoteAddress
    }
});

我不能说你的 Ghost 博客，但对于 Express，你可以像这样阅读 IP：

// Tell express it is behind a proxy, so it is safe to read the header
// to get its IP.
app.set('trust proxy', true);

function(req, res){
    // Express will get the IP from the header, or use the connection
    // address if there is no header.
    console.log(req.ip);
}
