How to sent empty parameters

[rkmax]

I'm having trouble with a site I need pass empty arguments on the query. example:

http://thehost.com?Subject=Hello+World&submit=

i trying to make

$client = new Client();
$response = $client->get("http://thehost.com", ['query' => ['Subject' => 'Hello World', 'submit => null']]);

but guzzle trim the submit parameter, how can solve this issue?

There are two different ways to do this:

1. Set a query value to an empty string (e.g., '') if you want the trailing "=". (i.e., a=)
2. Set a query value to null if do not want the trailing "=" (i.e., a).

<?php
require 'vendor/autoload.php';
use GuzzleHttp\Client;
$client  = new Client();

$request = $client->createRequest('GET', 'http://httpbin.org/get', [
    'query' => [
        'foo' => 'bar',
        'baz' => '', // sends trailing =
        'qux' => null // no trailing =
    ]
]);

echo $request->getUrl();

Outputs: http://httpbin.org/get?foo=bar&baz=&qux

thanks @mtdowling

And what about POST request? It should be always with trailing =.

@mtdowling When I set 'qux' => null, the qux param is not added at all. Has something changed during time? :) Thanks!

I had the same issue as @simPod said. Can we add some docs for this behavior?

Same issue... Any idea ? :)

guzzle/src/Client.php

Line 371 in 7bc46be

$value = http_build_query($value, null, '&', PHP_QUERY_RFC3986);

Having the same issue right now

'query' => [
                'input' => $search,
                'location' => $this->eventParameter['location'],
                'radius' => $this->eventParameter['radius'],
                'language' => $this->requestStack->getCurrentRequest()->getLocale(),
                'key' => $this->apiKey,
                'strictbounds' => NULL
            ]

The parameter strictbounds does not affect the result of the request.

Hi, is there any work around with this issue?

It seems, you have to build the query string manually (in guzzlehttp/guzzle since at least version 6.5.5), e.g.

<?php

require_once dirname(__FILE__) . '/../bootstrap.php';

use GuzzleHttp\Client;

$query = join('&', [
  http_build_query(
    [
      'foo' => 'bar',
      'baz' => '', // sends trailing =
    ],
    null, '&', PHP_QUERY_RFC3986
  ),
  'qux', // no trailing =
]);
echo $query . PHP_EOL; // foo=bar&baz=&qux

$client = new Client();
$response = $client->get("https://httpbin.org/get", ['query' => $query]);
echo $response->getBody();

since AFAIK neither Guzzle nor http_build_query support query parameters without value and no trailing =.
