Support personal access token

[kaakaa]

It seems that Mattermost is going to support personal access token for authenticating REST API from next version.
PLT-6763 Implement user access tokens and new roles (server-side) by jwilander · Pull Request #6972 · mattermost/platform
(user access token renamed personal access token later)

We should support authenticating by personal access token instead of user and password.

So we have to replace login() with another method, haven't we? What is the name of the method? I didn't find one in https://github.com/mattermost/platform/blob/master/model/client4.go

Sorry for my late reply.

If we use personal access token, we set AuthToken/AuthType directly to model.Client instead of using login() .
https://github.com/mattermost/mattermost-server/blob/master/model/client4.go#L463

The following code works fine for me.

package main

import (
	"log"

	"github.com/mattermost/platform/model"
)

const Token = "dummy_access_token"

func main() {
	c := model.NewAPIv4Client("http://localhost:8065")
	c.AuthToken = Token
	c.AuthType = model.HEADER_BEARER

	u, _ := c.GetMe("")
        log.Printf("%+v", u)
}

I have made a fork to test your solution. At the moment the matterpoll bot is working. I don´t made a Pull Request cause it´s hardcoded to only use the Token and in my version you have no chance to go back to User/Password authentication.

Matterpoll plugin doesn't need any authentication methods.
Please consider using this plugin.
