node.js - 为什么我导不了别人的数据

Question

var Client = require('/usr/local/lib/node_modules/mysql').Client;
var client = new Client();

client.user = 'root';
client.password = '';

console.log('Connecting to MySQL...');

client.query('USE tiny_shop'); //如果MySQL已建立库表。

http = require("http");

var server = http.createServer(function(request, response) {

response.writeHeader(200, {"Content-Type": "text/html"});

client.query('SELECT * FROM tags', function selectCb(err, results, fields) {  
    if (err) {  
        throw err;  
    }  

    var data = '';
    for (var i=0; i<results.length; i++) {          
        var firstResult = results[i];
        data += 'id: ' + firstResult['id']+'tag: ' + firstResult['tag']; 
    } 

    response.write(data); 
    response.end()
});

});

server.listen(8080);

var sys = require("util");
sys.puts("Server running at http://localhost:8080/"); //模块文件放在 /usr/local/lib/node_modules 这个目录下。
