Pull user and password for custom app auth

(Stephen Kerr Jr) #1

I am developing a new c# application and I was wondering if I would be able to query the Discourse database for a username and password, check if the password matches, then return a success or failure message. I can achieve this via PHP and MySQL currently, but I am not sure if Discourse would allow me to write a PostgresSQL query to access the user and password table to check authentication against. Is this possible? Hopefully my explanation is clear enough.

I found this topic here:

But it doesn’t give a specific example of validating a password. It actually states there is no password to validate against due to socket auth. How would you suggest confirming the user’s login from a 3rd party c# application? Token-based Auth?

Discourse can act as a provider of its own SSO, how about cooking up an implementation of that?

You have reference code in Discourse to go by for the client side already.

That is basically what I am looking for. Although as I was thinking a little more and I dont think I would be able to use social media logins if I am passing a username and password. Unless there is a simple way to possibly launch a browser, check if they are already logged in or have them login from that browser, then have the browser return a success or failure message… do you have further details on the code references?

You know, I was just thinking… I dont actually need to have the user put in their username or password…
All I would need to do is check to see if there is a user logged into discourse. if there is a user, i just need to retrieve what their username is. If there is not a user logged in, I would just need to open a browser and allow the user to login.

So is there an easy way to send a call to Discourse and find out if a user is currently logged in and determine what their username is?

Still looking for an easy way to call externally to a discourse forum and see if someone is already logged in or not. Does anyone know a good way to achieve this?

This might be what I am looking for:

now I will just have to test this out…

I attempted the above API call via PHP and had zero luck. Not sure what is happening, but I am definately not have much luck. Any suggestions for accessing the “current logged in user” via PHP API?

You can’t pull password period it is not stored in the DB. All we store is a salted hash.

The API for incoming SSO is documented in extreme detail here: Official Single-Sign-On for Discourse (sso)
