How to get subscriber in channel?

Thank you for your quick answer.

I understanded your answer like below.

var url=‘https://api.twitch.tv/kraken/channel’;

        var headersArray = [
            ['Authorization', 'OAuth ' + req.user.accessToken],
            ['Accept', 'application/vnd.twitchtv.v5+json'],
            ['Client_Id', config.twitchtv.clientID],                
        ];
        request({ 
            url: url, 
            method: 'GET', 
            headers: headersArray 
            }, 
            function (error, response, body) { 
            if (error) throw error; 
            console.log(body); 
            } 
        ); 

============================================

Is it correct?
The test result is below.

{“status”:400,“message”:“Invalid authorization code”}

I used accessToken that received token when twitch’s authentication.

Is my method correct ? or Which use token?
