Hook on a custom page

[Dinendal]

Hello there,

I'm writing a plugin to interconnect 2 systems.
I would like to know how to fire a hook from a specific custom page (i already create the page).

The purpose is :

• go to URL with parameters (ex. http://myaddress/myCustomPage?id=jklDGFYHcgfu)
• automatically fire a hook that call my plugin
• parse URL to get parameters (if you could explain how to get the current url in the plugin too, pls)
• do some stuff etc.

Could you please help me ?

Philippe.

The first part is ok, in my plugin.json I use :

{ "hook": "filter:MyTemplate.build", "method": "myMethod" }

So the plugin is called.

How could I get the current URL from there pls ?
I see another problem, the page load loops and seems to be stuck after my plugin code was successfully executed. Is there anything to do to let the main process continue ?

In your plugin method you can access the request object.

myPlugin.meyMethod = function (hookData, callback) {
    console.log(hookData.req.url);
    callback(null, hookData);
};

Thanks, it's working.
With that I fixed the endless loop too.

Is it possible to log in via a plugin ?
After verifying ID token from URL I need to log the user with his forum ID.

I checked some other plugins and I can't really figure out what part of code or function is used to log in users.

@dinendal Sure. It would be an unusual method of logging in, but there's nothing stopping your plugin from calling the login controller with the request object.

Another question again.
I'm trying to override the login with this skeleton : https://gist.github.com/julianlam/19deafaa4dbd624ceecd

It works fine but how could I intercept, in my plugin, the email and password from inputs of the login page ?

[yariplus]

@dinendal It's in the req.body object.

I use

authenticationController.doLogin

I have an error popup from Nodebb :

Session interrompue
Il semble que votre session ne soit plus active, ou que le serveur ne la reconnaisse plus. Merci de rafraîchir cette page.

and when I click on OK, i'm correctly log in.
What am I doing wrong ? Is there another thing to do to be log in properly ?

[Dinendal]

translation of the error : "It looks like your login session is no longer active, or no longer recognized by your server..."

Is there a step that i'm missing ? Because when I click on "OK", I'm logged in...

"authenticationController.doLogin" is not sufficient ?

[yariplus]

I don't think so, probably something to do with cookies changing. I'm guessing you need to call redirect or status.send to avoid the error.
