如何将上传文件通过管道传输到另一台服务器

Question

我有两个服务器。 server1将接收来自用户的上传请求，并将请求通过管道传送到server2以将文件上传到server2。这是我的server1代码

upload: function (req, res) {
        console.log(req.headers);
        console.log(req.body);
        req.pipe(request.post('http://localhost:1337/file/upload')).pipe(res);
}

这是server2的代码：

upload: function (req, res) {
        console.log(req.allParams());
        console.log(req.file());
        console.log(req.headers);
        if (req.file("mot")) {
            req.file('mot').upload({
                    dirname: require('path').resolve(sails.config.appPath, 'data')
                }, function (err, data) {
                    if (err) {
                        console.log(err);
                        return res.json({
                            failed: true
                        });
                    } else {
                        console.log("file uploaded");
                        return res.ok();
                    }
                }
            )
        }else{

        }
    }

在使用邮递员将上传请求直接发送到server2时起作用。但是当我向server1发送请求时，在server2上收到此错误：

{ Error: ETIMEOUT: An Upstream (`mot`) timed out waiting for file(s). No files were sent after waiting 10000ms.
    at Timeout.<anonymous> (/media/thanhtv/Data/bitbucket/nodejs/test/node_modules/skipper/standalone/Upstream/Upstream.js:62:15)
    at ontimeout (timers.js:436:11)
    at tryOnTimeout (timers.js:300:5)
    at listOnTimeout (timers.js:263:5)

  code: 'ETIMEOUT',
  message:
   'ETIMEOUT: An Upstream (`mot`) timed out waiting for file(s). No files were sent after waiting 10000ms.' }

请帮帮我。我在用帆。
