nodejs 与 mysql联接

首先安装Mysql 模块吧

npm install mysql

刚开始在网上搜索了一个测试代码,发现根本就连接不上mysql.

varClient=require('mysql').Client,
client =new Client(),

类似这样的.

查原因:

console.log(require("mysql"));

对象只有5个方法

createConnection

createPool

createQuery

escape

escapeId

没有Client 方法和 属性.

去mysql 模块目录查看了下 Readme.md

#Here is an example on how to use it:



```js

var mysql      = require('mysql');

var connection = mysql.createConnection({

  host     : 'localhost',

  user     : 'me',

  password : 'secret',

});



connection.connect();

看来网上的代码是有问题.应该是版本更新了不支持了.自己重新写了测试代码运行正常

// mysql.js

//加载mysql Module

var Client = require('mysql');



var db_options = {

    host: "localhost",

    port: 3306,

    user: "root",

    password: "123456",

    database: "drupal"

};

var client = Client.createConnection(db_options);



client.connect();



client.query(

  'SELECT * FROM actions',

  function selectCb(err, results, fields) {

    if (err) {

      throw err;

    }



    console.log(results);

    console.log(fields);

  }

);

client.end();
