cURL -d switch: How to use it in a guzzle request - php

Question

I'm learning to use an API. They provide an example of the following authentication code:
curl -X POST --header "Content-Type: application/json" --header "Accept: application/json" -d " {\"Username\": \"the_username\",
\"Password\": \"the_password\"}
" "https://someurl.someapi.com:443/api/Login/Authenticate"
However I need to reproduce this with a Guzzle request. Here is what I've been trying
$headers = [
"Content-Type" => "application/json",
"Accept" => 'application/json -d " {\"Username\": \"the_username\", \"Password\": \"the_password\" }" ',
];
// $headers = [
// "Content-Type" => "application/json"
// ];
$extra_data = ["proxy" => $proxy,
"headers" => $headers ];
// Defining the Guzzle Client to communicate with Legacy.com
$client = new Client([
// Base URI is used with relative requests
'base_uri' => 'https://someurl.someapi.com:443/api/Login/Authenticate',
// You can set any number of default request options.
'timeout' => 10.0,
]);
try {
$response = $client->request('POST', '', $extra_data);
}
However no matter what I try (this was the latest of my failed attempts), I can't get anything other than a code 400 error.

Answer 1

So I finally figured how to do this:
This code worked!
$str = json_decode('{ "Username": "' . $username . '", "Password": "' . $password . '"}',true);
var_dump($str);
if ($str == NULL) return;
$url_authenticate = "Login/Authenticate";
$extra_data = ["proxy" => $proxy,
"json" => $str ];
// Defining the Guzzle Client to communicate with Legacy.com
$client = new Client([
// Base URI is used with relative requests
'base_uri' => 'https://someurl.someapi.com:443/api/',
// You can set any number of default request options.
'timeout' => 10.0,
]);
try {
$response = $client->request('POST', $url_authenticate, $extra_data);
}
catch (Exception $e) {
echo 'Exception: ' . $e->getResponse()->getStatusCode() . "\n";
exit;
}
$body = $response->getBody();
echo $body;
The key was use the json field int the extra data and transform the json to php array using json_decode. I hope this helps someone else
