Add helpers to generate various authentication header types

[arunoda]

Add support for:

• Basic Auth
• Bearer Auth (OAuth)

I'm trying to make a POST request which requires a Basic Auth authorization. But it's not working, I wonder if it's impossible at this moment. Do you know what could be? Has something to do with the support you intend to implement on this Issue?

-Edit- I get the 401 status code. The exactly same authorization header on Postman works fine.

Hey, just appedning "Username:Password" is not enough. You need to encode that as Base64. That was the missing part here.
See: https://en.wikipedia.org/wiki/Basic_access_authentication#Protocol

I am planning to make some updates to Fetch this week. I will make sure to do this too.

Thank you! I would appreciate very much if you do this update. I bought you plugin because it's much more well documented than the other one on the marketplace. But only this issue is preventing me to achieve my goal.

But actually, what is your plan to adress this issue? Do you intend to create a Base64 Encode node so we can manually encode our string before adding it to the array? Or something else?

-Edit-
I was able to get it working! For people that might have the same problem on the future: You have to encode JUST the username:password to Base64, then you add the string "Basic " (atention to the space) before the encoded string. After that, you do exactly what is told on the examples of this plugin to add custom Headers.

The problem is: I was only able to encode the string to Base64 using a node from the competitor REST plugin. Now I will wait for Arunoda to create some solution to encode to Base64 on this plugin. It would be better to have everything needded on just one plugin.

@juninholiveira I will create a simple helper function to add the username & password & it'll create the whole auth header. I will ping you when it's available on the marketplace.

[juninholiveira]

@arunoda Amazing! Better than what I imagined. I will wait patiently.

@juninholiveira I just added support for this. Will available on the marketplace soon.
