Call Rest Api Using Zend\Http\Client Or Guzzle - rest

Question

I am calling magento2 API in laravel. Using curl, I am getting correct response but I want to call API using GuzzleHttp\Client or Zend\Http\Client.
How can I call my api using this, below is my curl code snippet:
$curl = curl_init();
$data=array('username'=>$vendordata['merchant_name'],'password'=>$vendordata['password'],'customer'=>['email'=>$vendordata['email'],"firstname"=> $vendordata['firstname'], "lastname"=> $vendordata['lastname']],"addresses"=> ["region"=> $vendordata['address'], "region_id"=> 0],"default_shipping"=> true,"default_billing"=>true,"telephone"=>$vendordata['contact_number']);
$postdata=json_encode($data);
curl_setopt_array($curl, array(
CURLOPT_URL => "http://10.10.10.7/magento2/rest/V1/customers",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $postdata,
CURLOPT_HTTPHEADER => array(
"authorization: OAuth oauth_consumer_key=\"sganfgvr2naxwmh21jgi5ffijuci0207\",oauth_token=\"d16pdq1avr1rs7h9745rc0x6py65a2vt\",oauth_signature_method=\"HMAC-SHA1\",oauth_timestamp=\"1518006201\",oauth_nonce=\"4ghORA\",oauth_version=\"1.0\",oauth_signature=\"Ztq5ErznqvCl18GomWv0F55t5OA%3D\"",
"cache-control: no-cache",
"content-type: application/json",
"postman-token: 5ec55151-3365-7ffc-a6a4-ce5fe5bc451f"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}

Answer 1

First, open the terminal and run this command to install Guzzle
composer require guzzlehttp/guzzle
Then add these lines to include guzzle in the specific controller.
use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Client;
Now, create a method you want to run to call the API and put the below code
$client = new Client(); //GuzzleHttp\Client
$result = $client->post('your-request-uri', [
'form_params' => [
'sample-form-data' => 'value'
]
]);
That's it!
Docs explain this pretty well : https://github.com/guzzle/guzzle

Here is the complete code when using guzzlehttp instead of curl
$client = new GuzzleHttp\Client();
$response = $client->request('POST', 'http://10.10.10.7/magento2/rest/V1/customers', array(
headers' => [
'Authorization' => 'OAuth oauth_consumer_key="sganfgvr2naxwmh21jgi5ffijuci0207",oauth_token="d16pdq1avr1rs7h9745rc0x6py65a2vt",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1518006201",oauth_nonce="4ghORA",oauth_version="1.0",oauth_signature="Ztq5ErznqvCl18GomWv0F55t5OA%3D',
'Cache-Control' => 'no-cache',
'Postman-Token' => '5ec55151-3365-7ffc-a6a4-ce5fe5bc451f'
],
'json' => $postdata
));
You also have to install following dependencies in your laravel project for PSR-7 support and look at this stackoverflow question as a reference:
composer require symfony/psr-http-message-bridge
composer require zendframework/zend-diactoros

Answer 3

That caused by you didn't define the Content-Type as application/json on HTTP Header. Please try this
$client = new GuzzleHttp\Client();
$response = $client->request('POST', 'http://10.10.10.7/magento2/rest/V1/customers', array(
headers' => [
'Content-Type' => 'application/json',
'Authorization' => 'OAuth oauth_consumer_key="sganfgvr2naxwmh21jgi5ffijuci0207",oauth_token="d16pdq1avr1rs7h9745rc0x6py65a2vt",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1518006201",oauth_nonce="4ghORA",oauth_version="1.0",oauth_signature="Ztq5ErznqvCl18GomWv0F55t5OA%3D',
'Cache-Control' => 'no-cache',
'Postman-Token' => '5ec55151-3365-7ffc-a6a4-ce5fe5bc451f'
],
'json' => $postdata
));
And don't forget to load the dependencies using composer
composer require symfony/psr-http-message-bridge
composer require zendframework/zend-diactoros
