ノード、Express 4、MongoDBをOpenshiftで使用してREST APIの開始を設定しました。私はそれを動作させることなく、さまざまな設定とセットアップを試みました。今、私のメインserver.jsは次のようになります。オープンモンゴ、ノード、エクスプレス4でRESTを開きます。応答していない
var AppContainer = function() {
// Scope.
var self = this;
/* ================================================================ */
/* Helper functions. */
/* ================================================================ */
/**
* Set up server IP address and port # using env variables/defaults.
*/
self.setupVariables = function() {
// Set the environment variables we need.
self.ipaddress = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
self.port = process.env.OPENSHIFT_NODEJS_PORT || 3000;
};
/**
* terminator === the termination handler
* Terminate server on receipt of the specified signal.
* @param {string} sig Signal to terminate on.
*/
self.terminator = function (sig) {
if (typeof sig === "string") {
console.log('%s: Received %s - terminating sample app ...',
Date(Date.now()), sig);
process.exit(1);
}
console.log('%s: Node server stopped.', Date(Date.now()));
};
/**
* Setup termination handlers (for exit and a list of signals).
*/
self.setupTerminationHandlers = function() {
// Process on exit and signals.
process.on('exit', function() {
self.terminator();
});
// Removed 'SIGPIPE' from the list - bugz 852598.
['SIGHUP', 'SIGINT', 'SIGQUIT', 'SIGILL', 'SIGTRAP', 'SIGABRT',
'SIGBUS', 'SIGFPE', 'SIGUSR1', 'SIGSEGV', 'SIGUSR2', 'SIGTERM'
].forEach(function (element, index, array) {
process.on(element, function() {
self.terminator(element);
});
});
};
/**
* Initializes the sample application.
*/
self.initialize = function() {
self.setupVariables();
self.setupTerminationHandlers();
};
self.setupServer = function() {
/**
* Module dependencies.
*/
var app = require('./app');
var http = require('http');
/**
* Get port from environment and store in Express.
*/
// var port = normalizePort(self.port);
/**
* Create HTTP server.
*/
var server = http.createServer(app);
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(self.port, self.ipaddress, function() {
console.log('%s: Node server started on %s:%d ...',
Date(Date.now()), self.ipaddress, self.port);
});
server.on('error', onError);
server.on('listening', onListening);
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
console.log('Server on port : ' + addr.port);
}
};
};
var zapp = new AppContainer();
zapp.initialize();
zapp.setupServer();
と私のapp.jsは次のようになります。
const http = require('http'),
fs = require('fs'),
path = require('path'),
contentTypes = require('./utils/content-types'),
sysInfo = require('./utils/sys-info'),
env = process.env,
v1Route = require('./src/resources/v1/v1Route'),
MongoClient = require('mongodb').MongoClient;
var express = require('express');
var app = express();
var connection_string = '127.0.0.1:27017/datecal';
// if OPENSHIFT env variables are present, use the available connection info:
if(process.env.OPENSHIFT_MONGODB_DB_PASSWORD){
connection_string = process.env.OPENSHIFT_MONGODB_DB_USERNAME + ":" +
process.env.OPENSHIFT_MONGODB_DB_PASSWORD + "@" +
process.env.OPENSHIFT_MONGODB_DB_HOST + ':' +
process.env.OPENSHIFT_MONGODB_DB_PORT + '/' +
process.env.OPENSHIFT_APP_NAME;
}
var mongoUrl = 'mongodb://' + connection_string
MongoClient.connect(mongoUrl, function (err, db) {
if (err) {
console.log("Unable to connect to the mongoDB server. Error:", err);
} else {
//HURRAY!! We are connected. :)
console.log("Connection established to Mongo DB with connection string " + connection_string);
app.use('/v1', function(req, res, next){
req.db = db;
console.log("DB now available for all routes");
next();
});
app.use('/v1', v1Route);
// let port = process.env.OPENSHIFT_NODEJS_PORT || 3000;
// var ipaddress = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
// app.listen(port, ipaddress, function(){
// console.log('Server is now listening to port ' + port + ' on ip ' + ipaddress);
// });
}
});
module.exports = app;
問題がコミットすると実行しているとき、それは私のローカル環境ではうまく動作しますが、ということですopenshiftで私はサーバーが応答しないことを得る。 OPENSHIFT_NODEJS_PORTは8080です。これでserver.jsに自分のサーバーをセットアップしました。
また、app.jsの最後にコメント欄を使用してみました。私のセットアップで考慮していないオープンシフト環境や、何が間違っていますか？
