使用MongoSkin重新连接MongoDB ( Nodejs )

Question

我一直使用MongoSkin( Nodejs )插件连接Mongodb，如下所示。

    var db = mongo.db(dbconfig.mongo_ip+'/'+dbconfig.mongo_db_name);
    db.collection('myprofile').findOne({_id:memberid}, function(err, session){

        if(err){
            db.close();
            console.log(err.stack);
        }

    })

如果我从node.js得到了mongo连接错误，那么我如何使用mongoskin重新连接相同的连接，

Mongo Connect errr: Error: failed to connect to [localhost:27017]
    at [object Object].<anonymous> (/usr/local/lib/node_modules/mongoskin/node_modules/mongodb/lib/mongodb/connection/server.js:184:51)
    at [object Object].emit (events.js:45:17)
    at [object Object].<anonymous> (/usr/local/lib/node_modules/mongoskin/node_modules/mongodb/lib/mongodb/connection/connection_pool.js:110:14)
    at [object Object].emit (events.js:45:17)
    at Socket.<anonymous> (/usr/local/lib/node_modules/mongoskin/node_modules/mongodb/lib/mongodb/connection/connection.js:301:10)
    at Socket.emit (events.js:42:17)
    at Array.33 (net.js:799:27)
    at EventEmitter._tickCallback (node.js:108:26)

请在这方面帮帮我。

一个很好的起点是

https://github.com/kissjs/node-mongoskin/blob/master/test/db.js

但我假设你需要在mongoskin和驱动程序中调用db上的open。
