GETパラメータ、POSTパラメータ取得
概要
GETパラメータはreq.queryで、POSTパラメータはreq.bodyより取得する
サンプル
app.js
/**
* Module dependencies.
*/
var express = require('express')
, routes = require('./routes')
, user = require('./routes/user')
, test = require('./routes/test') // 追加
, param1 = require('./routes/get_param') // 追加
, param2 = require('./routes/post_param') // 追加
, http = require('http')
, path = require('path');
var app = express();
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
});
app.configure('development', function(){
app.use(express.errorHandler());
});
// ルーティングメソッド設定
app.get('/', routes.index);
app.get('/users', user.list);
app.get('/test', test.index); // 追加
app.get('/test/main', test.main); // 追加
app.get('/param1', param1.index); // 追加
app.get('/param1/form', param1.form); // 追加
app.get('/param2', param2.index); // 追加
app.post('/param2/form', param2.form); // 追加
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
