Node.js issue with mongodb

Question

我在项目的最顶层目录中运行了node server.js：
这就是我得到的错误：

connect.multipart() will be removed in connect 3.0
visit https://github.com/senchalabs/connect/wiki/Connect-3.0 for alternatives
connect.limit() will be removed in connect 3.0
The magic happens on port 8080
events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: failed to connect to [your_database_here:27017]

    at emit (events.js:106:17)

    at net.js:833:16
    at process._tickCallback (node.js:419:13)

我已经安装了mongodb，当我在浏览器中打开localhost:27017时，它显示It looks like you are trying to access MongoDB over HTTP on the native driver port.。确切的错误在哪里？

我建议您使用"mongoose"从节点连接mongodb。以下是执行此操作的示例代码。

var mongoose=require('mongoose'),
    db = 'mongodb://localhost/test';
mongoose.connect(db);
//and your code goes here

您必须安装节点模块"mongoose"。阅读猫鼬的文档。
