Using Guzzle 6 in Laravel to communicate with an external API - php

Question

When I do this on the commandline:
curl -X POST -d '{"userDetails":{"username":"myself","password":"Myself123"}}' https://sub.domain.com/energy/api/login
it returns a sessionid like expected.
When I use Guzzle 6 on Laravel 5.5 and do this:
$client = new GuzzleHttp\Client();
$login = $client->post('https://sub.domain.com/energy/api/login', [
'userDetails' => [
'username' => 'myself',
'password' => 'Myself123'
]
]);
I get this error:
Server error: `POST https://sub.domain.com/energy/api/login` resulted in a `503 Service Unavailable` response: org.json.JSONException: JSONObject["userDetails"] not found.
What am I doing wrong?

Answer 1

Use this to debug and send request, sample here.
include these in class
//FOR GUZZLE
use GuzzleHttp\Client;
use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Exception\ServerException;
use GuzzleHttp\Exception\BadResponseException;
use GuzzleHttp\Exception\ClientException;
try{
$endPoint = "http://server_ip/security/subject";
$options = [ "auth" => [$username, $password], "headers" => ["header1" => value, "header2" => value] ];
$client = new Client();
$response = $client->get($endPoint, $options);
$responseArray = json_decode($response->getBody()->getContents(), true);
$status = $response->getStatusCode();
}catch(BadResponseException $e){
$response = $e->getResponse();
$reason = $response->getReasonPhrase();
$exceptionMessage = (!empty($reason)) ? $reason. ' email or password.' : 'Unauthorized email or password.';
}

You are not passing as a json. Try this:
$req = [
'userDetails' => [
'username' => 'myself',
'password' => 'Myself123'
]
];
$client = new GuzzleHttp\Client();
$login = $client->post('https://sub.domain.com/energy/api/login',
[
'json' => $req
]
);
return $login;
