URLs with query parameters

How to use URL and URLSearchParams imported from jslib.k6.io to construct URLs with/without query parameters.

URL

1import { URL } from 'https://jslib.k6.io/url/1.0.0/index.js';
2import http from 'k6/http';
3
4export default function () {
5  const url = new URL('https://k6.io');
6
7  url.searchParams.append('utm_medium', 'organic');
8  url.searchParams.append('utm_source', 'test');
9  url.searchParams.append('multiple', ['foo', 'bar']);
10
11  const res = http.get(url.toString());
12  // https://k6.io?utm_medium=organic&utm_source=test&multiple=foo%2Cbar
13}

Name	Type	Description
URLSearchParams(init)	Constructor	init Optional: One of [USVString, sequence of pairs or record ]
toString()	Method	Returns a USVString containing the whole URL
hash	Property	A USVString containing a '#' followed by the fragment identifier of the URL.
host	Property	A USVString containing the host, that is the hostname, and then, if the port of the URL is nonempty, a ':', followed by the port of the URL.
hostname	Property	A USVString containing the domain name of the URL.
href	Property	Returns a USVString containing the whole URL.
origin	Property	Returns a USVString containing the origin of the URL, that is its scheme, its domain and its port.
password	Property	A USVString containing the password specified before the domain name.
pathname	Property	Is a USVString containing an initial '/' followed by the path of the URL, not including the query string or fragment.
port	Property	A USVString containing the port number of the URL.
protocol	Property	A USVString containing the protocol scheme of the URL, including the final ':'.
search	Property	A USVString indicating the URL's parameter string; if any parameters are provided, this string includes all of them, beginning with the leading ? character.
searchParams	Property	A URLSearchParams object which can be used to access the individual query parameters found in search.
username	Property	A USVString containing the username specified before the domain name.

URLSearchParams

1import { URLSearchParams } from 'https://jslib.k6.io/url/1.0.0/index.js';
2import http from 'k6/http';
3
4export default function () {
5  const searchParams = new URLSearchParams([
6    ['utm_medium', 'organic'],
7    ['utm_source', 'test'],
8    ['multiple', 'foo'],
9    ['multiple', 'bar'],
10  ]);
11
12  const res = http.get(`${'https://k6.io'}?${searchParams.toString()}`);
13  // https://k6.io?utm_medium=organic&utm_source=test&multiple=foo&multiple=bar
14}

Name	Type	Description
URLSearchParams(init)	Constructor	init Optional: One of [USVString, sequence of pairs or record ]
toString()	Method	Returns a query string (questionmark is omitted).
append()	Method	Appends a specified key/value pair as a new search parameter.
delete()	Method	Deletes the given search parameter, and its associated value, from the list of all search parameters.
entries()	Method	Returns an iterator allowing iteration through all key/value pairs contained in this object.
forEach()	Method	Allows iteration through all values contained in this object via a callback function. callback(value, key).
get()	Method	Returns the first value associated with the given search parameter.
getAll()	Method	Returns all the values associated with a given search parameter.
has()	Method	Returns a Boolean that indicates whether a parameter with the specified name exists.
keys()	Method	Returns an iterator allowing iteration through all keys of the key/value pairs contained in this object.
values()	Method	Returns an iterator allowing iteration through all values of the key/value pairs contained in this object.
set()	Method	Sets the value associated with a given search parameter to the given value. If there were several matching values, this method deletes the others. If the search parameter doesn't exist, this method creates it.
sort()	Method	Sorts all key/value pairs, if any, by their keys.
