#This url define speific Target for guzzle
$url = 'http://www.google.com';
#guzzle
try {
# guzzle post request example with form parameter
$response = $client->request( 'POST',
$url,
[ 'form_params'
=> [ 'processId' => '2' ]
]
);
#guzzle repose for future use
echo $response->getStatusCode(); // 200
echo $response->getReasonPhrase(); // OK
echo $response->getProtocolVersion(); // 1.1
echo $response->getBody();
} catch (GuzzleHttp\Exception\BadResponseException $e) {
#guzzle repose for future use
$response = $e->getResponse();
$responseBodyAsString = $response->getBody()->getContents();
print_r($responseBodyAsString);
}

You can integrate Guzzle into Codeigniter 3.x by following the following steps:
NOTE: I was doing this on Windows, should work on other platforms too.
Open the command terminal on your computer
Change directory to your Codeigniter app installation (i.e. my app is called MyCodeigniterApp)
cd C:\wamp64\www\MyCodeigniterApp
Install Composer in that directory by running the following command on the terminal
curl -sS https://getcomposer.org/installer | php
After installing Composer, we can now install Guzzle by running the following command on the terminal
composer require guzzlehttp/guzzle
if you encounter the following error while executing the above command
follow the recommendation in the error message.
Open composer.json located in your App root folder i.e. C:\wamp64\www\MyCodeigniterApp
then change
"mikey179/vfsStream": "1.1.*"
to
"mikey179/vfsstream": "1.1.*"
You can now re-run the command in step 4 to install Guzzle
After successful installation of Guzzle, you now need to make the following changes to the config.php file under the application/config directory
make the following changes under Composer auto-loading section and let the configuration be:
$config['composer_autoload'] = 'vendor/autoload.php';
The integration is complete, now you can use Guzzle in your controllers or models as below or by following the guides from Guzzle documentation on https://docs.guzzlephp.org/en/stable/
//Create guzzle http client
$client = new \GuzzleHttp\Client();
$res = $client->request('GET', 'https://api.github.com/user', [
'auth' => ['user', 'pass']
]);
echo $res->getStatusCode();
// "200"
echo $res->getHeader('content-type')[0];
// 'application/json; charset=utf8'
echo $res->getBody();
// {"type":"User"...'
DONE.......
