How to log cookies from a cookie jar? - node.js

Question

How can I log cookies that are stored in a cookie jar using the request-promise npm module.
I have tried printing the cookie jar variable but as expected that does not work.
How I am creating the jar,
var request = require('request-promise');
var sess = request.jar()
The code sending the request,
request({url: myurl, jar: sess}, function () {
request(
{
url: 'myurl',
method: 'POST',
headers: [
{
"Accept": "application/json",
}
],
postData: {
"xqr":"1"
}
}
)
I expect all the cookies used to send my request to be printed out using console.log()

Answer 1

request uses tough-cookie internally. So you can easily access to tough-cookie store which is an abstract class and use its prototype function getAllCookies.
function logCookies(jar){
jar._jar.store.getAllCookies(function(err, cookieArray) {
if(err) throw new Error("Failed to get cookies");
console.log(JSON.stringify(cookieArray, null, 4));
});
}
And this will log all cookies and its properties.
[
{
"key": "1P_JAR",
"value": "1P_JAR_VALUE",
"expires": "2019-01-23T20:09:38.000Z",
"domain": "google.com",
"path": "/",
"hostOnly": false,
"creation": "2018-12-24T20:09:37.800Z",
"lastAccessed": "2018-12-24T20:09:38.097Z"
},
{
"key": "NID",
"value": "NID_VALUE",
"expires": "2019-06-25T20:09:38.000Z",
"domain": "google.com",
"path": "/",
"httpOnly": true,
"hostOnly": false,
"creation": "2018-12-24T20:09:37.802Z",
"lastAccessed": "2018-12-24T20:09:38.098Z"
}
]
If you only want to get raw cookie string you can just simply use
console.log(cookieArray.map(cookie => cookie.toString()))
And it will give you
[
'1P_JAR=1P_JAR_VALUE; Expires=Wed, 23 Jan 2019 20:15:02 GMT; Domain=google.com; Path=/',
'NID=NID_VALUE; Expires=Tue, 25 Jun 2019 20:15:02 GMT; Domain=google.com; Path=/; HttpOnly'
