每当您调用它时，它看起来db.collection都会创建一个 EventEmitter。您是否应该尝试在请求处理程序之外缓存集合：

var logs = db.collection('logs');

var insertErrorLog = function (req, res) {
  var pathname = url.parse(req.url).pathname;
  var ua = req.headers['user-agent'];     // user-agent header from an HTTP request
  var details = parser.setUA(ua).getResult();
  var params = url.parse(req.url,true).query;

  logs.insert({…});

快速查看代码表明它应该始终返回相同的实例，但我看不出您的问题的任何其他原因：
