无法连接到谷歌云服务使用node.js

Question

我想连接到我的谷歌云-SQL实例使用我的node.js mysql模块，我无法连接到它。我提到了以下链接mysql docs和google getting started，但无法理解发生了什么。

var connection = mysql.createConnection({ 
    acquireTimeout: 30000, 
    host : '35.184.77.86', 
    user  : 'XXX', 
    password : 'XXX', 
    database : 'name', 
}); 

connection.connect(function(err){ 

    if (err) { 
     console.error(chalk.red('error connecting: ' + err.stack)); 
     return; 
    } 
    console.log(chalk.green('connected as id ' + connection.threadId)); 
}); 

connection.query('SELECT * FROM likes', function(err, rows, fields) 
{ 
    if (err) { 
     console.log(chalk.red(err)); 
    }else{ 
    console.log(fields); 
    } 
}); 

connection.end(); 

我收到以下错误，同时连接。

尝试运行下面的代码也检查连接和正确的IP。服务器和系统之间可能存在内部防火墙块

con.connect(function(err) { 
    if (err) throw err; 
    console.log("Connected!"); 
});
