我正在使用nodejs和
mongodb在openShift上构建一个应用程序.我也在使用mongoose并尝试连接此代码
var url = process.env.OPENSHIFT_MONGODB_DB_URL;
var db = mongoose.connect(
url,function(err) {
console.log("Error loading the db...");
});
解决方法
您可以尝试以下模式：
server.js
// call the packages we need
var express = require('express');
var app = express();
var mongoose = require('mongoose');
var url = '127.0.0.1:27017/' + process.env.OPENSHIFT_APP_NAME;
// if OPENSHIFT env variables are present,use the available connection info:
if (process.env.OPENSHIFT_MONGODB_DB_URL) {
url = process.env.OPENSHIFT_MONGODB_DB_URL +
process.env.OPENSHIFT_APP_NAME;
}
// Connect to mongodb
var connect = function () {
mongoose.connect(url);
};
connect();
var db = mongoose.connection;
db.on('error',function(error){
console.log("Error loading the db - "+ error);
});
db.on('disconnected',connect);
