在我的本地PC中，我设置了一个Node.js代理服务器，它向node.js RESTful MongoDb服务器发出请求，其中一个位于端口8080处，在端口3000 代理，我可以在REST风格的服务器日志，所有的疑问都正确发送回代理看，但代理挂断引发此错误：套接字挂在http.request到Node.js MongoDb服务器
events.js:72
throw er; // Unhandled 'error' event
^
Error: socket hang up
at createHangUpError (http.js:1472:15)
at Socket.socketOnEnd [as onend] (http.js:1568:23)

at Socket.EventEmitter.emit (events.js:117:20)
at _stream_readable.js:920:16
at process._tickCallback (node.js:415:13)
这就是我建立了我的代理请求：
var proxy = function(req, res, next) {
try {
var options = mapRequest(req);
var dbReq = http.request(options, function(dbRes) {
var data = "";
res.headers = dbRes.headers;
dbRes.setEncoding('utf8');
dbRes.on('data', function(chunk) {
data = data + chunk;
});
dbRes.on('end', function() {
res.header('Content-Type', 'application/json');
res.statusCode = dbRes.statusCode;
res.httpVersion = dbRes.httpVersion;
res.trailers = dbRes.trailers;
res.send(data);
res.end();
});
});
dbReq.end(JSON.stringify(req.body));
} catch (error) {
console.log('ERROR: ', error.stack);
res.json(error);
res.end();
}
};
这些是发送到MongoDB服务器的选项：
