我正在編寫這個小型RESTful應用程序,它將請求發送到不同的URL。爲此,我使用nodejs,並表示設置不同的路徑。作爲一個數據庫,我正在計劃使用monogoDB(由christkv提供的node-mongodb-native)。使用express和mongoDB的NodeJS應用程序
我的代碼(不包括蒙戈嘗試)是這樣的:
app.js
/**
* Module dependencies.
*/
var express = require('express')
, routes = require('./routes')
var app = module.exports = express.createServer();
var Db = require('mongodb').Db;
var Server = require('mongodb').Server;
var client = new Db('test', new Server('127.0.0.1', 27017, {}));
// Configuration
app.configure(function() {
app.set('views', __dirname + '/views');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
app.configure('development', function() {
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});
app.configure('production', function() {
app.use(express.errorHandler());
});
var insertData = function(err, collection) {
collection.insert({name: "Kristiono Setyadi"});
collection.insert({name: "Meghan Gill"});
collection.insert({name: "Spiderman"});
}
// Routes
app.post('/', routes.syncServiceIndex);
app.post('/syncService', routes.synchServicePost);
app.get('/syncService/:syncServiceUser/sync', routes.synchServiceSync);
app.post('/syncService/:syncServiceUser/push', routes.synchServicePush);
app.del('/syncService/:syncServiceUser', routes.synchServiceDel);
app.post('/syncService/:syncServiceUser/contacts/push', routes.synchServiceContactsPush);
app.get('/syncService/:syncServiceUser/contacts/sync', routes.synchServiceContactsSync);
app.post('/syncService/:syncServiceUser/contacts/', routes.synchServiceContactsPost);
app.get('/syncService/:syncServiceUser/contacts/:contactId', routes.synchServiceContactsGet);
app.put('/syncService/:syncServiceUser/contacts/:contactId', routes.synchServiceContactsPut);
app.del('/syncService/:syncServiceUser/contacts/:contactId', routes.synchServiceContactsDel);
app.listen(3000);
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
,並保持在不同的文件不同組件的緣故,這是我的文件,每個URL代碼:
index.js
//var ObjectID = db.bson_serializer.ObjectID;
exports.syncServiceIndex = function(req, res) {
console.log('syncServiceIndex');
//console.log("BODY:" + JSON.stringify(req.body));
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServicePost = function(req, res) {
console.log('synchServicePost');
console.log("BODY:" + JSON.stringify(req.body));
var jsonObject = JSON.parse(JSON.stringify(req.body));
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceSync = function(req, res) {
console.log('synchServiceSync');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServicePush = function(req, res) {
console.log('synchServicePush');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceDel = function(req, res) {
console.log('synchServiceDel');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceDel = function(req, res) {
console.log('synchServiceDel');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsPush = function(req, res) {
console.log('synchServiceContactsPush');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsSync = function(req, res) {
console.log('synchServiceContactsSync');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsPost = function(req, res) {
console.log('synchServiceContactsPost');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsGet = function(req, res) {
console.log('synchServiceContactsGet');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsPut = function(req, res) {
console.log('synchServiceContactsPut');
res.statusCode = 200;
res.send("OK\n");
};
exports.synchServiceContactsDel = function(req, res) {
console.log('synchServiceContactsDel');
res.statusCode = 200;
res.send("OK\n");
};
從我看到一些示例代碼,我已經檢查了,我才真正只使用一個打開的連接,這是我應該有我所有的代碼在
client.open(function(err, pClient) {
});
電話。我遇到的問題是我不確定如何傳遞客戶端或集合,以便我可以使用index.js文件中的數據庫。有沒有一種方法可以在當前佈局中做到這一點,還是我必須移動一些東西?
爲什麼要在client.open回調中包裝路由?如果我也使用mongoskin,我還必須這樣做嗎? – georgesamper 2012-06-10 13:50:00
