Use async and await keywords to obtain THE API Access Token

Directly on the code:

const request = require('request-promise-native');
 
var config = require('.. /config.js');
 
async function getAccessToken(){
    var raw = new Buffer(config.username + ":" + config.password);
    const accessToken = await request({
        method: 'GET'.headers: {
            'Authorization': 'Basic ' + raw.toString('base64')},url: config.ACCESS_TOKEN,
        json: false
    });
   
    return accessToken;
}

module.exports = getAccessToken;
Copy the code

Consumption Code:

accessTokenService().then(function(oResult){
    console.log(oResult);
});
Copy the code

After stepping, the debugger skips the getAccessToken function at line 7. Line 16 also skips the getAccessToken function without stepping. After a few seconds, the breakpoint is triggered directly from the return keyword on line 16.

At this point, the accessToken variable contains a pure Access Token, not a wrapped promise object.

However, the entire async function ends up returning a Promise object that contains the access token obtained using the then method provided by the Promise object:
