后台proxy代理通过Node.js获取数据返回生成Echarts(MySQL)

Node.js连接mysql

下载

npm install --save mysql

为了方便，我先封装成Util类

MysqlClient.js

require('./util/CommonUtil');
var mysql = require('mysql');
var config = require('./config/config').mysql;

MysqlClient = function() {};

MysqlClient.query = function(dataBase, sql, callback) {
    var pool = mysql.createPool({
        host: config.host,
        port: config.port,
        user: config.user,
        password: config.password,
        database: dataBase
    });
    pool.getConnection(function(err, connection) {
        console.log('## sql: ' + sql);
        connection.query(sql, "", function(err, result) {
            if (err) {
                console.log('[queryBySql error] - ', err.message);
                return;
            }
            callback(result);
        });
        connection.release();
    });
};
