Logging in programmatically from another application

  • GNU/Linux Admin

    @jewa name is something unique, as the comment indicates. For example, if your site is "Example Widgets and Stuff", use something like example.

    When the end user clicks on the link in the login/registration page, it should send them to /auth/example (if example was the name, as above), which would redirect them to the authorizationURL as defined in your plugin.

    From there, it's up to your site to send them back with the proper token or code.


  • @julian I see. I thought all the user needed to do was to log in on my site and when he clicks on the forum link on my website there would be a handshake between my website and nodebb and then sign him on. I didn´t know he had to click on the log in/register link on nodebb.

    I still have some questions though:

    1. So I have to make a page and endpoint for /auth/example right? I believe oauth2orize would be responsible for the redirection.

    2. I read your code and you always append callback if I am to make an endpoint or page it would never be executed because I would have /auth/example whilst the plugin would contain /auth/example/callback.

    I think the process is a bit clearer to me right now. I have been programming javascript and node for about 3 months which is not much admittedly but this is hands down the most complicated thing I have come across as I don't have a full grasp of the whole process and it has very little to do with your programming skills imo and more to do with how much you understand libraries and all.


  • @jewa so I am getting there. I finally noticed a button- alternative registration/log in.

    I clicked it and hurrah I got an error that should help at last:

    It still has to do with the call back uri. I really don't know what to do next since the url points to nodebb and not to me so I can't create an endpoint or something.

    I am not so sure but I have a little idea of what my problem is but even at that I don't know how to solve it. I traced the error logs to an oauth2 file and it requests that the page returns between 200 and 299 status code but mine is returning 500. How can I return 200 when the link is not on my site. I am really getting confused.


  • @julian this is to hoping you'd help me complete this hurdle. As shown in the picture, I am getting the code but I don't know what to make of the error I am getting. I tried to deploy nodebb on Heroku since the error could possibly be because I am using local host but I ran into other issues with nodebb crashing on Heroku and that is like opening two battle fronts needlessly. I think I would proceed one step at a time.

    Like I said, when I run my authorizationUrl on my browser, it gives an error 401 with the grant code. The resource I saw online said this was perfectly normal. If I copy the code and make a post request for my token on PostMan, it exchanges the code for a token and then I complete by posting to my user endpoint to get user details so I think the whole process is working and possibly I am just one correction away from saving you the stress of having to answer someone else trying to do this on node js because as I mentioned earlier, I will write down what worked for me and the resources I used.


  • @julian I have been patiently waiting for a response. However, I tried to install nodebb on heroku. It was a painful process but I came to my wits ends when I got to the launch page. It says congratulations your nodebb has been setup but won't get past that page. It returns a 404 error whilst making a get request for /admin.

    Here are the logs

  • Global Moderator Plugin & Theme Dev

    @jewa what Node version? Try Node 6 if you're on a newer version.


  • @PitaJ I am on node 6.9.2. I will uninstall that and install node 6.0.0.

    Update I have tried it still returns the same error.

  • Global Moderator Plugin & Theme Dev

    @jewa you shouldn't need to downgrade then. Any version of Node 6.x.x should work.

  • GNU/Linux Admin

    @jewa That error doesn't seem related to logging in programmatically... sounds like you have a plugin or theme installed that relies on async v1... are you on the develop branch?


  • @julian I am on nodebb version 1.4.3 not sure if that is develop branch as I am not so good with git. Yes it is not related. I just wanted to isolate the cause of my failure to log in programmatically by hosting on Heroku and trying it from there.

    I followed the steps here: https://community.nodebb.org/topic/9049/getting-nodebb-and-plugins-setup-with-heroku-and-mongodb

    and then modified web.js line 34 inside the install folder to port = process.env.PORT || port; Otherwise, it would load at port 4567 which was always failing. I think I also added process.env.PORT to line 145 in loader.js but I don't think that changed anything much. It only started nodebb when I modified web.js


  • @julian @pitaJ So I burnt the whole thing down. Cloned version 1.3.0 and re-installed. It broke down without modifying web.js so I modified it and it gave me the same error as before. What do I do?

  • GNU/Linux Admin

    Do not use Heroku as that is not a standard deployment environment for us.


  • @julian I have ditched Heroku. Deployed the app on cloud9 and it is working fine. I then try to use my plugin and I still get the same error. Here is the error on nodebb

    I am really frustrated I have searched the internet for help the only help I get is with respect to a possible typo or firewall. My authorization codes are being created in my database it is just at the exchange point that the failure happens.

    It is a pretty awful user experience to log into the forum after logging into my web app.

    Would definitely be using nodebb for a stand-alone forum but this is me giving up after a 4 day battle. I might as well have built a very simple forum for my website in those 4 days. Ugh!!!

  • GNU/Linux Admin

    @jewa Looks like you've cut off the error at the top there, so I can't see the issue.


  • @julian I have been struggling to replicate the error. But I would post it once I manage to replicate it.
