with the same code, the request signature we calculated does not match the signature you provided?

[yshengwu]

On Windows 10, with the same code, I get the order normally with getOrder(), but I get an error with getOrders()

code: ..... //Create the request signer which will be automatically used to sign all of the //requests to the API $signer = new DoubleBreak\Spapi\Signer();

//Create Credentials service and call getCredentials() to obtain //all the tokens needed under the hood

$credentials = new DoubleBreak\Spapi\Credentials($tokenStorage, $signer, $config); $cred = $credentials->getCredentials();

$spapi = new DoubleBreak\Spapi\Api\Orders($cred, $config); / $order_id = '113-3351006-381xx02'; $response = $spapi->getOrder($order_id); print_r($response);exit; /

$params = [ 'MarketplaceIds' => ['ATVPDKIKX0DER'], / 'LastUpdatedAfter'=> '2021-06-02T09:46:28Z', / ]; $response = $spapi->getOrders($params); print_r($response);exit;

error info: Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: GET https://sellingpartnerapi-na.amazon.com/orders/v0/orders?MarketplaceIds%5B0%5D=ATVPDKIKX0DER resulted in a 403 Forbidden response: { "errors": [ { "message": "The request signature we calculated does not match the signature you provided.

read my question - https://github.com/double-break/spapi-php/issues/40 it has solution to fix the signature issue -

Also in order to satisfy amazon signature version 4 does not match error - I fixed it by creating a function for encoding marketplace id array square brackets using this function in client.php and replaced at line number 57 & 62 - public function custombuildquery($params, $encoding = PHP_QUERY_RFC3986) { if (!$params) { return ''; }

if ($encoding === false) { $encoder = function ($str) { return $str; }; } elseif ($encoding === PHP_QUERY_RFC3986) { $encoder = 'rawurlencode'; } elseif ($encoding === PHP_QUERY_RFC1738) { $encoder = 'urlencode'; } else { throw new \InvalidArgumentException('Invalid type'); }

$qs = ''; foreach ($params as $k => $v) { $k = $encoder($k); if (!is_array($v)) { $qs .= $k; if ($v !== null) { $qs .= '=' . $encoder($v); } $qs .= '&'; } else { foreach ($v as $aindex=>$vv) { $qs .= $k.rawurlencode('['.$aindex.']'); if ($vv !== null) { $qs .= '=' . $encoder($vv); } $qs .= '&'; } } }

return $qs ? (string) substr($qs, 0, -1) : ''; }
