Cookies Example

import http from "k6/http";
import { check, group } from "k6";

export default function() {
    // Since this request redirects the `res.cookies` property won't contain the cookies
    let res = http.get("http://httpbin.org/cookies/set?name1=value1&name2=value2");
    check(res, {
        "status is 200": (r) => r.status === 200
    });

    // Make sure cookies have been added to VU cookie jar
    let vuJar = http.cookieJar();
    let cookiesForURL = vuJar.cookiesForURL(res.url);
    check(null, {
        "vu jar has cookie 'name1'": () => cookiesForURL.name1.length > 0,
        "vu jar has cookie 'name2'": () => cookiesForURL.name2.length > 0
    });
}

// Example showing two methods how to log all cookies (with attributes) from a HTTP response.

import http from "k6/http";

function logCookie(cookie) {
    // Here we log the name and value of the cookie along with additional attributes.
    // For full list of attributes see: https://k6.io/docs/using-k6/cookies#properties-of-a-response-cookie-object
    console.log(`${cookie.name}: ${cookie.value}\n\tdomain: ${cookie.domain}\n\tpath: ${cookie.path}\n\texpires: ${cookie.expires}\n\thttpOnly: ${cookie.http_only}`);
}

export default function() {
    let res = http.get("https://www.google.com/");

    // Method 1: Use for-loop and check for non-inherited properties
    for (var name in res.cookies) {
        if (res.cookies.hasOwnProperty(name) !== undefined) {
            logCookie(res.cookies[name][0]);
        }
    }

    // Method 2: Use ES6 Map to loop over Object entries
    new Map(Object.entries(res.cookies)).forEach((v, k) => logCookie(v[0]) );
}

import http from "k6/http";
import { check } from "k6";

export default function() {
    // Get VU cookie jar and add a cookie to it providing the parameters
    // that a request must match (domain, path, HTTPS or not etc.)
    // to have the cookie attached to it when sent to the server.
    let jar = http.cookieJar();
    jar.set("https://httpbin.org/cookies", "my_cookie", "hello world",
            { domain: "httpbin.org", path: "/cookies", secure: true, max_age: 600 });

    // As the following request is matching the above cookie in terms of domain,
    // path, HTTPS (secure) and will happen within the specified "age" limit, the
    // cookie will be attached to this request.
    let res = http.get("https://httpbin.org/cookies");
    check(res, {
        "has status 200": (r) => r.status === 200,

        "cookie has correct value": (r) => r.json().cookies.my_cookie == "hello world"
    });
