Can you include raw JSON in Guzzle POST Body? - php

Question

This should be soo simple but I have spent hours searching for the answer and am truly stuck. I am building a basic Laravel application and am using Guzzle to replace the CURL request I am making at the moment. All the CURL functions utilise raw JSON variables in the body.
I am trying to create a working Guzzle client but the server is respsonding with 'invalid request' and I am just wondering if something fishy is going on with the JSON I am posting. I am starting to wonder if you can not use raw JSON in the Guzzle POST request body? I know the headers are working as I am receiving a valid response from the server and I know the JSON is valid as it is currently working in a CURL request. So I am stuck :-(
Any help would be sooo greatly appreciated.
$headers = array(
'NETOAPI_KEY' => env('NETO_API_KEY'),
'Content-Type' => 'application/json',
'Accept' => 'application/json',
'NETOAPI_ACTION' => 'GetOrder'
);
// JSON Data for API post
$GetOrder = '{
"Filter": {
"OrderID": "N10139",
"OutputSelector": [
"OrderStatus"
]
}
}';
$client = new client();
$res = $client->post(env('NETO_API_URL'), [ 'headers' => $headers ], [ 'body' => $GetOrder ]);
return $res->getBody();

Answer 1

You can send a regular array as JSON via the 'json' request option; this will also automatically set the right headers:
$headers = [
'NETOAPI_KEY' => env('NETO_API_KEY'),
'Accept' => 'application/json',
'NETOAPI_ACTION' => 'GetOrder'
];
$GetOrder = [
'Filter' => [
'OrderID' => 'N10139',
'OutputSelector' => ['OrderStatus'],
],
];
$client = new client();
$res = $client->post(env('NETO_API_URL'), [
'headers' => $headers,
'json' => $GetOrder,
]);
Note that Guzzle applies json_encode() without any options behind the scenes; if you need any customisation, you're advised to do some of the work yourself
$res = $client->post(env('NETO_API_URL'), [
'headers' => $headers + ['Content-Type' => 'application/json'],
'body' => json_encode($getOrders, ...),
]);

Guzzle 7 Here
The below worked for me with raw json input
$data = array(
'customer' => '89090',
'username' => 'app',
'password' => 'pwd'
);
$url = "http://someendpoint/API/Login";
$client = new \GuzzleHttp\Client();
$response = $client->post($url, [
'headers' => ['Content-Type' => 'application/json', 'Accept' => 'application/json'],
'body' => json_encode($data)
]);
print_r(json_decode($response->getBody(), true));
For some reasons until I used the json_decode on the response, the output wasn't formatted.

You probably need to set the body mime type. This can be done easily using the setBody() method.
$request = $client->post(env('NETO_API_URL'), ['headers' => $headers]);
$request->setBody($GetOrder, 'application/json');
