mongodb由mongoskin错误连接

Question

我尝试过使用mongoskin节点模块连接mongo db下面提到的代码。

var mongo = require('mongoskin');
var db = mongo.db("localhost:27017/mydb");
db.bind('mycollection');
db.mycollection.find().toArray(function(err, items) {
console.log(items)
        db.close();
});

我得到了下面提到的错误。

/usr/local/lib/node_modules/mongoskin/node_modules/mongodb/lib/mongodb/connection/url_parser.js:15
    throw Error("URL must be in the format mongodb://user:pass@host:port/dbnam
          ^
Error: URL must be in the format mongodb://user:pass@host:port/dbname

    at SkinClass.(anonymous function) [as toArray] (/usr/local/lib/node_modules/mongoskin/lib/utils.js:116:14)

在这个错误中，它提到了输入用户名和密码，我没有用户名和pasword.What，我必须输入，请帮助我。

• 我的mongodb版本是v1.8.2，
• 节点版本为v0.10.28，
• mongoskin版本为v1.4.4。

Answer 1

错误说：

 throw Error("URL must be in the format mongodb://user:pass@host:port/dbnam")

你试过加入协议了吗？(即：)

    var db = mongo.db("mongodb://localhost:27017/mydb");

Answer 2

答案在于错误本身：

throw Error("URL must be in the format mongodb://user:pass@host:port/dbnam
      ^
Error: URL must be in the format mongodb://user:pass@host:port/dbname

如果你不明白，请按下面提到的做：

var mongo = require('mongoskin');
var db = mongo.db("mongodb://localhost:27017/mydb");
db.bind('mycollection');
db.mycollection.find().toArray(function(err, items) 
{
    console.log(items)
    db.close();
});
