从Heroku连接到MongoLab时,应用程序超时 [英] application times out when connecting to MongoLab from Heroku
问题描述
我在Heroku上托管一个node.js应用程序,并尝试使用节点模块node-mongodb-native连接到MongoLab以进行连接。我的应用程序在从连接到MongoLab的本地主机上运行时工作正常,但是在部署到Heroku之后,我得到一个应用程序错误H12(请求超时)。
示例代码:$ b $
app.get('/',function(req,res){
require('mongodb')。connect(mongourl,函数(err,conn){
conn.collection('mycollection',函数(err,coll){
coll.find()。toArray(function(error,results){
if (error)console.log(error)
else {
res.send(util.inspect(results));
}
});
});
});
});
是否有其他选项需要传递给。 b
$ b
非常感谢任何建议。
如果有其他人有这个问题:
现在可以选择你想在Heroku上运行的节点版本。所以通过将下面的代码添加到我的package.json中,我能够连接到MongoLab没有问题:
engines:{
node:0.6.12
,npm:1.1.4
}
谢谢。
I am hosting a node.js application on Heroku and trying to connect to MongoLab using the node module node-mongodb-native to connect. My application works fine when run from localhost connecting to MongoLab, but after deploying to Heroku I get an Application Error H12 (Request timeout).
Sample code:
app.get('/', function(req, res) {
require('mongodb').connect(mongourl, function(err, conn){
conn.collection('mycollection', function(err, coll){
coll.find().toArray(function(error, results) {
if(error) console.log(error)
else {
res.send(util.inspect(results));
}
});
});
});
});
Are there additional options I need to pass to .connect() from Heroku?
Any suggestions are greatly appreciated. Thanks!
In case anyone else has this issue:
It is now possible to choose what version of node you would like to run on Heroku. So by adding the following code to my package.json I was able to connect to MongoLab no problem:
"engines": {
"node": "0.6.12"
, "npm": "1.1.4"
}
Thanks.
