Question

我正在尝试使用我的node.js mysql模块连接到我的google-cloud-sql实例，但我无法连接到它。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();

连接时出现以下错误。

尝试使用以下代码运行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!");
});

无法使用node.js连接到Google Cloud sql服务
