[NodeJS] 建置記錄

1.建立新專案︰

$ express --view=pug nodeservice

create : nodeservice
create : nodeservice/package.json
create : nodeservice/app.js
create : nodeservice/public
create : nodeservice/public/stylesheets
create : nodeservice/public/stylesheets/style.css
create : nodeservice/public/images
create : nodeservice/routes
create : nodeservice/routes/index.js
create : nodeservice/routes/users.js
create : nodeservice/public/javascripts
create : nodeservice/views
create : nodeservice/views/index.pug
create : nodeservice/views/layout.pug
create : nodeservice/views/error.pug
create : nodeservice/bin
create : nodeservice/bin/www

install dependencies:
$ cd nodeservice && npm install

run the app:
$ DEBUG=nodeservice:* npm start

2.安裝相依項目(install dependencies 同上面所寫)

$ cd nodeservice && npm install

以下是目前會用的到，也一起安裝

npm install date-utils --save
npm install fs --save
npm install quick-local-ip --save
npm install mongodb --save

3.在console.log上加上時間
在app.js上增加

require('date-utils');
// log override
console.log=(function() {
      var orig = console.log;
      return function() {
        try {
          var tmp=process.stdout;
          process.stdout=process.stderr;
          // get now
          var now = new Date();
          // format time
          var now_formated = now.toFormat("YYYY-MM-DD HH24:MI:SS");
          var strDate = '[' + now_formated + '] ';
          if (Buffer.isBuffer(arguments[0])) {
            arguments[0] = strDate + arguments[0];
          } else if (typeof arguments[0] !== 'object') {
            arguments[0] = strDate + arguments[0];
          } else if (typeof arguments[0] === 'object') {
            arguments[0] = strDate + JSON.stringify(arguments[0]);
          }
          orig.apply(console, arguments);
        } finally {
          process.stdout=tmp;
        }
    };
})();

4.啟動Server時在Log上印出server的url︰
在bin/www增加

var myip = require('quick-local-ip');
function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Local IP: ' + myip.getLocalIP4() + ' Listening on ' + bind);
  debug('http://' + myip.getLocalIP4() + ':' + addr.port);
}

5.啟動Server

$ DEBUG=nodeservice:* npm start
> nodeservice@0.0.0 start /Users/kirk/Documents/NodeProjects/nodeservice
> node ./bin/www

nodeservice:server Local IP: 192.168.3.35 Listening on port 3000 +0ms
nodeservice:server http://192.168.3.35:3000 +2ms

6.取資料

//HttpHeader:
var udid = req.headers['udid'];
//Post Attribute:
var product = req.body.product;
//Get QueryString:
router.get('/WTXO', function(req, res, next)
var m = req.query.m;
//Get from RESTFUL Url
router.get('/WTXO/:t', function(req, res, next)
var month = req.params.t;

以上。
