MongoDB: Error setting TTL index on collection : sessions

由 狂风中的少年 提交于 2019-11-28 17:36:19
Initially this error message started appearing very infrequently, but started to appear more regularly and now appears 4/5 times I run my application. I'm handling my session store with Mongo and as I understand it, the TTL index is used to make the session data expire. /home/dan/dev/audio-wave/node_modules/connect-mongo/lib/connect-mongo.js:161 throw new Error('Error setting TTL index on collection : ' + s ^ Error: Error setting TTL index on collection : sessions at /home/dan/dev/audio-wave/node_modules/connect-mongo/lib/connect-mongo.js:161:23 at /home/dan/dev/audio-wave/node_modules/connect

Node.js express correct use of bodyParser middleware

由 心已入冬 提交于 2019-11-28 17:15:23
I am new to node.js and express and have been experimenting with them for a while. Now I am confused with the design of the express framework related to parsing the request body. From the official guide of express: app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(app.router); app.use(logErrors); app.use(clientErrorHandler); app.use(errorHandler); After setting up all the middleware, then we add the route that we want to handle: app.post('/test', function(req, res){ //do something with req.body }); The problem with this approach is that all request body will be parsed

What is the session's “secret” option?

由 不问归期 提交于 2019-11-28 16:08:27
问题 I don't know anything about cryptography. I'm wondering what the session secret is. I see code like this: app.use(express.session({ store: mongoStore({ url: app.set('db-uri') }), secret: 'topsecret' })); What is the secret and should I change it? 回答1: Yes, you should change it. A session secret in connect is simply used to compute the hash . Without the string, access to the session would essentially be "denied". Take a look at the connect docs, that should help a little bit. 回答2: The secret

How to implement CSRF protection in Ajax calls using express.js (looking for complete example)?

由 一个人想着一个人 提交于 2019-11-28 15:25:10
问题 I am trying to implement CSRF protection in an app built using node.js using the express.js framework. The app makes abundant use of Ajax post calls to the server. I understand that the connect framework provides CSRF middleware, but I am not sure how to implement it in the scope of client-side Ajax post requests. There are bits and pieces about this in other Questions posted here in stackoverflow, but I have yet to find a reasonably complete example of how to implement it from both the

Everyauth vs Passport.js?

由 丶灬走出姿态 提交于 2019-11-28 15:02:52
Everyauth and Passport.js seem to have very similar feature sets. What are some of the positive and negative comparisons between the two that would make me want to use one over the other? Chiming in with my two cents, as the developer of Passport . Before developing Passport, I evaluated everyauth and determined that it didn't meet my requirements. So, I set about implementing a different solution which would. The major points I wanted to address are: Idiomatic Node.js everyauth makes extensive use of promises, instead of Node's approach of using callbacks and closures. Promises are an

问题 Updade: Ok so I've fixed my previous problem (Besides the SQLinjection which I'm not sure how to patch but for now it's unimportant) however I need to get it to detect Male or Female and strip some characters from it too... This is the code I did for that I defined the variable here: $gender = $response["registration"]["gender"]; I then defined newgender here $new_gender = "F"; However I then added an if statement which was supposed to detect if it was Male and change it to "M" if($gender ==

Java URLConnection - When do I need to use the connect() method?

由 北战南征 提交于 2019-11-28 09:37:20
I have a problem to understand the meaning of the connect() method in the URLConnection class. In the following code, if I use the connect() method, I get the same result if I don't use it. Why (or when) do I need to use it? URL u = new URL("http://example.com"); HttpURLConnection conn = (HttpURLConnection) u.openConnection(); conn.connect();//with or without it I have the same result InputStream in = conn.getInputStream(); int b; while ((b = in.read()) != -1) { System.out.write(b); } Amanda HttpURLConnection conn = (HttpURLConnection) u.openConnection(); only creates an Object connect()
