1.想要参考:

Node-restify 简介

去试试其:

https://github.com/roymax/moquery/tree/master

可惜结果安装hiredis就出错了:

所以,暂时放弃。

2.参考:

nodejs操作mysql的尝试

去折腾一下mysql。

CLi@PC-CLI-1 /cygdrive/d/tmp/tmp_dev_root/node.js
$ npm install mysql
npm http GET https://registry.npmjs.org/mysql
npm http 200 https://registry.npmjs.org/mysql
npm http GET https://registry.npmjs.org/mysql/-/mysql-2.0.0-alpha4.tgz
npm http 200 https://registry.npmjs.org/mysql/-/mysql-2.0.0-alpha4.tgz
npm http GET https://registry.npmjs.org/require-all/0.0.3
npm http 200 https://registry.npmjs.org/require-all/0.0.3
npm http GET https://registry.npmjs.org/require-all/-/require-all-0.0.3.tgz
npm http 200 https://registry.npmjs.org/require-all/-/require-all-0.0.3.tgz
mysql@2.0.0-alpha4 node_modules\mysql
└── require-all@0.0.3

然后拷贝其代码,去做测试,结果出错,现已解决:

【已解决】Node.js中测试mysql的代码var client = mysql.createClient运行出错:TypeError: Object # has no method ‘createClient’

3.继续参考:

Getting started with Restify using Node.js and CoffeeScript

去先安装npm install coffee-script。

不过后来也懒得继续折腾了关于coffee-script东西了。

4.最后,使用的,可以运行的js是:

var restify = require('restify');
var mysql   = require('mysql');

var server = restify.createServer({
  name: 'crifanRestifyServer',
  version: '1.0.0'
});
server.use(restify.acceptParser(server.acceptable));
server.use(restify.queryParser());
server.use(restify.bodyParser());


// server.get('/echo/:name', function (req, res, next) {
  // res.send(req.params);
  // return next();
// });

// function respond(req, res, next) {
  // res.send('hello ' + req.params.name);
// }

// server.get('/hello/:name', respond);


//==================================================================================================
// GET  /db/table               get all database tables
// GET  /db/table/table_name    get the specific database table by name
// POST /db/table               add a new database table, provide in json format, with name and value
//==================================================================================================
var connection = mysql.createConnection({
    host : 'localhost',
    user : 'root',
    password : '',
});

var db_name = "crifan_db";
var table_name = "crifan_db_table";

//create database
connection.query('CREATE DATABASE '+ db_name, function(err) {
  if (err && err.number != mysql.ERROR_DB_CREATE_EXISTS) {
    //throw err;
    console.log("already exist database:" + db_name);
  }
});
connection.query('USE ' + db_name);

function queryTable(req, res, next)
{
    console.log("queryTable be called");

    //var queryResult;
    
    connection.query(
      'SELECT * FROM '+table_name,
      function selectCb(err, results, fields) {
        if (err) {
          throw err;
        }
        
        console.log("now send result");
        res.send(results);
     
        //console.log(results);
        //queryResult = results;
        //console.log(fields);
        
        //connection.end();
      }
    );
    
    
}

server.get('/db', queryTable);

function createTable(req, res, next)
{
    console.log("createTable be called");
    //console.log(req);
    //console.log(req.params);
    var jsonParams = req.params;
    for(var key in jsonParams)
    {
        console.log(key);
    }
    
    //console.log("------------------");
    console.log(req.body);

    //create table
    // connection.query(
      // 'CREATE TABLE ' + table_name +
      // '(id INT(11) AUTO_INCREMENT, '+
      // 'name VARCHAR(255), '+
      // 'PRIMARY KEY (id))', function(err) {
      // if (err && err.number != mysql.ER_TABLE_EXISTS_ERROR) {
        // //throw err;
        // console.log("already exist table:" + table_name);
      // }
    // }
    // );
    
    connection.query(
      'CREATE TABLE ' + table_name +
      '(name VARCHAR(255), '+
      'PRIMARY KEY (name))', function(err) {
      if (err && err.number != mysql.ER_TABLE_EXISTS_ERROR) {
        //throw err;
        console.log("already exist table:" + table_name);
      }
    }
    );
    
    console.log("create table OK");
    
    var curDate = new Date();
    var curMilliSec = curDate.getTime();
    connection.query(
      'INSERT INTO '+table_name+' '+
      'SET name = ?',
      ['table_'+curMilliSec]
    );
     
    // var query = connection.query(
      // 'INSERT INTO '+table_name+' '+
      // 'SET name = ?',
      // ['nodejs2']
    // );
    
   res.send("new table create OK");
   return next();
}

server.post('/db', createTable);

// server.head('/hello/:name', respond);

server.listen(2012, function () {
  console.log('%s listening at %s', server.name, server.url);
});

存为server.js

然后通过

node server.js

去运行。

然后客户端,通过curl操作:

"new table create OK"

对应的,也可以去通过之前安装的MyPhpMyAdmin,查看到对应的mysql中的,的确创建了对于的database和table了。

 

其中,要注意,第一次是需要先运行下面的带POST的,去创建好对应的数据库,后续才可以通过GET去获得的。

否则先运行GET,由于没有数据库的table,所以肯定会出错的。
