empty/null response

[elr0berto]

My code:

<?php
require_once(__DIR__.'/vendor/swish-php/vendor/autoload.php');

use HelmutSchneider\Swish\Client;
use HelmutSchneider\Swish\Util;

// Swish CA root cert
$rootCert = __DIR__.'/../swish/cert_test/ca.crt'; // forwarded to guzzle's "verify" option

// .pem-bundle containing your client cert and it's corresponding private key. forwarded to guzzle's "cert" option
$clientCert = [__DIR__.'/../swish/cert_test/cl.pem', 'swish'];

$client = Client::make($rootCert, $clientCert, Client::SWISH_TEST_URL);

$response = $client->createPaymentRequest([
                                              'callbackUrl' => 'https://localhost/swish',
                                              'payeePaymentReference' => '12345',
                                              'payerAlias' => '4671234768',
                                              'payeeAlias' => '1231181189',
                                              'amount' => '100',
                                              'currency' => 'SEK',
                                          ]);

$data = Util::decodeResponse($response, true);
var_dump($response->getBody()); // empty stream 
var_dump($response); // show "Created" and statusCode 201 .. so seems successful?!
var_dump($data); // NULL

Any idea why I don't get a full response?

Please refer to the official swish docs. This library is not doing any manipulation of the responses so if you're getting 200 OK back you should be all good. Copy-pasta from the docs, section 11.1.3:

curl -v --request POST https://swicpc.bankgirot.se/swishcpcapi/api/v1/paymentrequests
\
 --header "Content-Type: application/json" \
 --data @- <<!
{
 "payeePaymentReference": "0123456789",
 "callbackUrl": "https://example.com/api/swishcb/paymentrequests",
 "payerAlias": "46701234567",
 "payeeAlias": "1234760039",
 "amount": "100",
 "currency": "SEK",
 "message": "Kingston USB Flash Drive 8 GB"
}

As you can see the response only contains a header with a link to the payment request. You may use this method to extract the ID.

It works when i get the response from $client->getPaymentRequest() and then decode it .. not sure why... anyway, I'm happy that this works now :)

Thanks for the good work Helmut :)

$id = Util::getPaymentRequestIdFromResponse($res); $res = $client->getPaymentRequest($id); $body = Util::decodeResponse($res); // now it works ..
