So long story short i was stuck with this old PHP utility that is using an old zend framework. I am having trouble when it times-out it doesnt retry so it fails. i have done everything from changing timeout timers to changing max redirects and everything else i can do with the settings and still get the same thing.
I get a consistent
Fatal error: Uncaught exception 'Zend_Http_Client_Exception' with message 'Unable to read response, or response is empty'
and if i happen to try it enough it will work without issue. its just getting to retry it is the problem.
Im not sure where to think to put the retry logic.
I've seen some say it would go somewhere here (Zend_http_client)
public function request($method = null)
{
if (! $this->uri instanceof Zend_Uri_Http) {
/** #see Zend_Http_Client_Exception */
require_once 'Zend/Http/Client/Exception.php';
throw new Zend_Http_Client_Exception('No valid URI has been passed to the client');
}
if ($method) {
$this->setMethod($method);
}
$this->redirectCounter = 0;
$response = null;
// Make sure the adapter is loaded
if ($this->adapter == null) {
$this->setAdapter($this->config['adapter']);
}
// Send the first request. If redirected, continue.
do {
// Clone the URI and add the additional GET parameters to it
$uri = clone $this->uri;
if (! empty($this->paramsGet)) {
$query = $uri->getQuery();
if (! empty($query)) {
$query .= '&';
}
$query .= http_build_query($this->paramsGet, null, '&');
$uri->setQuery($query);
}
$body = $this->_prepareBody();
$headers = $this->_prepareHeaders();
// Open the connection, send the request and read the response
$this->adapter->connect($uri->getHost(), $uri->getPort(),
($uri->getScheme() == 'https' ? true : false));
$this->last_request = $this->adapter->write($this->method,
$uri, $this->config['httpversion'], $headers, $body);
$response = $this->adapter->read();
if (! $response) {
/** #see Zend_Http_Client_Exception */
require_once 'Zend/Http/Client/Exception.php';
throw new Zend_Http_Client_Exception('Unable to read response, or response is empty');
}
$response = Zend_Http_Response::fromString($response);
if ($this->config['storeresponse']) {
$this->last_response = $response;
}
I was thinking it could also go here (in my own code)
$eventResponse = new Response($Client->Event(
$theEvent,null));
if (!$throwEventResponse->getResponseStatusOk()) {
$ex = new ResponseException("Unable to complete event.");
$ex->setErrorList($throwEventResponse->getErrorList());
throw $ex;
}
Im at a bit of a loss and im not sure how to go about it to best work for what i need.
Thanks in advance!
Found that by changing the type of HTTP request from HTML 1.1 to 1.0 fixed the issue i was having with the calls moving to the next without waiting for the previous call to finish.
pushing the second request before the other was done caused a weird caching issue and the request failed.

I'm implementing gocardless api in my website. I'm stuck in webhook. When i'm sending an webhook from sandbox test environment into my website, it showing 200 response, but after that no code is executing. and also i'm not seeing anything in response body, its showing null.
I'm using laravel 5.7 for that. Here is my code
route.php
Route::post('/webhook', 'HomeController#webhook');
HomeController.php
public function webhook()
{
$webhook_endpoint_secret = env("GOCARDLESS_WEBHOOK_ENDPOINT_SECRET");
$request_body = file_get_contents('php://input');
$headers = getallheaders();
$signature_header = $headers["Webhook-Signature"];
try {
$events = Webhook::parse($request_body, $signature_header, $webhook_endpoint_secret);
foreach ($events as $event) {
print("Processing event " . $event->id . "\n");
switch ($event->resource_type) {
case "mandates":
$this->process_mandate_event($event);
break;
default:
print("Don't know how to process an event with resource_type " . $event->resource_type . "\n");
break;
}
}
header("HTTP/1.1 204 OK");
} catch(InvalidSignatureException $e) {
header("HTTP/1.1 498 Invalid Token");
}
}
public function process_mandate_event($event)
{
switch ($event->action) {
case "cancelled":
print("Mandate " . $event->links["mandate"] . " has been cancelled!\n");
break;
default:
print("Don't know how to process a mandate " . $event->action . " event\n");
break;
}
}
I tried to execute some database query, nothing is working anyway. Can anyone point me out what and where i'm doing wrong?
$responseBody = file_get_contents('php://input');
if ($responseBody <> "") {
$response_new = json_decode($responseBody, true);
foreach ($response_new["events"] as $event) {
print_r($event); // you will see all the data which you want
//if($event['resource_type'] == 'subscriptions')
//payments,mandates or etc...
//
}
}
use email sending the code to debugging, when webhook called, email sends to your address with response body then you will data in the email body.
Hope you understand
The best way to handle the webhooks with Laravel and it's structure is to add a Middleware to verify the webhook signature:
public function handle($request, Closure $next)
{
$signature = $request->header('Webhook-Signature');
if (!$signature) {
throw WebhookFailed::missingSignature();
}
if (!$this->isValid($signature, $request->getContent(), $request->route('configKey'))) {
throw WebhookFailed::invalidSignature($signature);
}
return $next($request);
}
The isValid method will check the signature of the webhook and your saved secret.
Then at your controller, you can handle the events that come from the webhook (remember that Gocardless can send more than one event in a single webhook request).
public function __invoke(Request $request)
{
$payload = $request->input();
foreach ($payload['events'] as $event) {
// Do whatever do you need with the events.
}
}
return response()->json(['message' => 'ok']);
}
We have created a package for Laravel can help you with the handling and processing of the Gocardless webhooks.
Nestednet/Gocardless-laravel
Got the solution. I was having the problem while getting the headers values. In laravel you can't get header value using $headers = getallheaders(); You need to use use Request; and then Request::header("Webhook-Signature"); which then solved my problem.
searching for a good authentication method for my rest api i came a cross this :
"What is stateless authentication?
Again, stateless means without state. But, how can we identify a user from a token without having any state on the server? Surprisingly, it’s very easy! just send all the data to the client.
So what would you store/send (send to client/network)? The most trivial example is an access token. Access tokens usually have a unique ID, an expiration date and the ID of the client that created it. To store this, you would just put this data into a JSON object, and encode it using base64."
Now, having a self-contained token, you will need to make sure that nobody can manipulate the data. For this you should sign it using MAC algorithm or any other digital signature method available.
This is a little confusing for me , how can i validate the access token when the request comes(nothing stored to match it), but i find it a good idea and i want to implement it, any advice will be very helpful.
My rest api is very simple I receive every request to index.php , then i create new object with the request class to analyze every element of the request.
request class looks like this :
<?php
class Request {
public $url_elements;
public $verb;
public $parameters;
public function __construct() {
$this->verb = $_SERVER['REQUEST_METHOD'];
$this->url_elements = explode('/', $_SERVER['PATH_INFO']);
$this->parseIncomingParams();
$this->format = 'json';
if(isset($this->parameters['format'])) {
$this->format = $this->parameters['format'];
}
return true;
}
public function parseIncomingParams() {
$parameters = array();
if (isset($_SERVER['QUERY_STRING'])) {
parse_str($_SERVER['QUERY_STRING'], $parameters);
}
$body = file_get_contents("php://input");
$content_type = false;
if(isset($_SERVER['CONTENT_TYPE'])) {
$content_type = $_SERVER['CONTENT_TYPE'];
}
switch($content_type) {
case "application/json":
$body_params = json_decode($body);
if($body_params) {
foreach($body_params as $param_name => $param_value) {
$parameters[$param_name] = $param_value;
}
}
$this->format = "json";
break;
case "application/x-www-form-urlencoded":
parse_str($body, $postvars);
foreach($postvars as $field => $value) {
$parameters[$field] = $value;
}
$this->format = "html";
break;
default:
break;
}
$this->parameters = $parameters;
}
}
?>
After this i proceed with the proper controller that is the first element after index.php/
Thank you very much for your time and sorry if the question is not very clear as i am new to rest :/
I am currently working with the Amazon MWS to integrate some features into wordpress via a plugin. I am using the client libraries provided by amazon found here:
https://developer.amazonservices.com/api.html?group=bde§ion=reports&version=latest
Using these client libraries and the sample php files included I have set up my plugin to make two API calls. The first is requestReport
public function requestInventoryReport() {
AWI_Amazon_Config::defineCredentials(); // Defines data for API Call
$serviceUrl = "https://mws.amazonservices.com";
$config = array (
'ServiceURL' => $serviceUrl,
'ProxyHost' => null,
'ProxyPort' => -1,
'MaxErrorRetry' => 3,
);
$service = new MarketplaceWebService_Client(
AWS_ACCESS_KEY_ID,
AWS_SECRET_ACCESS_KEY,
$config,
APPLICATION_NAME,
APPLICATION_VERSION);
$request = new MarketplaceWebService_Model_RequestReportRequest();
$request->setMerchant(MERCHANT_ID);
$request->setReportType('_GET_MERCHANT_LISTINGS_DATA_');
self::invokeRequestReport($service, $request);
}
private function invokeRequestReport(MarketplaceWebService_Interface $service, $request) {
try {
$response = $service->requestReport($request);
if ($response->isSetRequestReportResult()) {
// Print Out Data
}
} catch (MarketplaceWebService_Exception $ex) {
// Print Out Error
}
}
and the second is getReportRequestList which has code similar to the first function. I am able to run these functions without any errors. The issue that I am having is that $response->isSetRequestReportResult() returns false. From my understanding and looking into the response object, this would suggest that the response object does not have the result. (Upon printing out the response object I can see that the FieldValue of the result array is NULL.) The call, however, does not throw an error but neither does it have the result.
I did some digging through the code and found that the result does actually get returned from the api call but never gets set to the return object when the library attempts to parse it from XML. I've tracked the error down to this block of code (This code is untouched by me and directly from the amazon mws reports library).
private function fromDOMElement(DOMElement $dom)
{
$xpath = new DOMXPath($dom->ownerDocument);
$xpath->registerNamespace('a', 'http://mws.amazonaws.com/doc/2009-01-01/');
foreach ($this->fields as $fieldName => $field) {
$fieldType = $field['FieldType'];
if (is_array($fieldType)) {
if ($this->isComplexType($fieldType[0])) {
// Handle Data
} else {
// Handle Data
}
} else {
if ($this->isComplexType($fieldType)) {
// Handle Data
} else {
$element = $xpath->query("./a:$fieldName/text()", $dom);
$data = null;
if ($element->length == 1) {
switch($this->fields[$fieldName]['FieldType']) {
case 'DateTime':
$data = new DateTime($element->item(0)->data,
new DateTimeZone('UTC'));
break;
case 'bool':
$value = $element->item(0)->data;
$data = $value === 'true' ? true : false;
break;
default:
$data = $element->item(0)->data;
break;
}
$this->fields[$fieldName]['FieldValue'] = $data;
}
}
}
}
}
The data that should go into the RequestReportResult exists at the beginning of this function as a node in the dom element. The flow of logic takes it into the last else statement inside the foreach. The code runs its query and returns $element however $element->length = 13 in my case which causes it to fail the if statement and never set the data to the object. I have also looked into $element->item(0) to see what was in it and it appears to be a dom object itself matching the original dom object but with a bunch of empty strings.
Now, I'm new to working with the MWS and my gut feeling is that I am missing a parameter somewhere in my api call that is messing up how the data is returned and is causing this weird error, but I'm out of ideas at this point. If anyone has any ideas or could point me in the right direction, I would greatly appreciate it.
Thanks for your time!
** Also as a side note, Amazon Scratchpad does return everything properly using the same parameters that I am using in my code **
These works for me, check if you are missing anything.
For RequestReportRequest i am doing this:
$request = new MarketplaceWebService_Model_RequestReportRequest();
$marketplaceIdArray = array("Id" => array($pos_data['marketplace_id']));
$request->setMarketplaceIdList($marketplaceIdArray);
$request->setMerchant($pos_data['merchant_id']);
$request->setReportType($this->report_type);
For GetReportRequestList i am doing this:
$service = new MarketplaceWebService_Client($pos_data['aws_access_key'], $pos_data['aws_secret_access_key'], $pos_data['config'], $pos_data['application_name'], $pos_data['application_version']);
$report_request = new MarketplaceWebService_Model_GetReportRequestListRequest();
$report_request->setMerchant($pos_data["merchant_id"]);
$report_type_request = new MarketplaceWebService_Model_TypeList();
$report_type_request->setType($this->report_type);
$report_request->setReportTypeList($report_type_request);
$report_request_status = $this->invokeGetReportRequestList($service, $report_request, $report_requestID);
I am trying to setup an Oauth server using the pecl-php oauth library http://php.net/manual/en/book.oauth.php
This code assumes that the client has already received a user verified access token, for simplicity sake I've not included any database calls and have hardcoded matching values into my client and provider.
Class OauthVerify
{
private static $consumer_secret = 'f63ed7f7a8899e59d3848085c9668a0d';
private static $token_secret = '72814e6059441037152eecef2e8559a748b84259';
private $provider;
public function __construct()
{
$this->provider = new OAuthProvider();
$this->provider->consumerHandler(array($this,'consumerHandler'));
$this->provider->timestampNonceHandler(array($this,'timestampNonceHandler'));
$this->provider->tokenHandler(array($this,'checkAccessToken'));
}
//Check the client request
public function checkRequest()
{
try {
$this->provider->checkOAuthRequest();
} catch (Exception $Exception) {
return OAuthProvider::reportProblem($Exception);
}
return true;
}
public static function timestampNonceHandler($Provider)
{
//I'm leaving out this logic now, to keep it simple and for testing purposes
return OAUTH_OK;
}
public static function consumerHandler($Provider)
{
//I'm leaving out this logic now, to keep it simple and for testing purposes
$Provider->consumer_secret = self::$consumer_secret;
return OAUTH_OK;
}
public static function checkAccessToken($Provider)
{
$Provider->token_secret = self::$token_secret;
return OAUTH_OK;
}
}
The above code should give me the barebones I need to authenticate an Oauth request.
Before any particular route is executed I call the $OauthVerify->checkRequest() method which checks if the client request is valid, however the server keeps throwing a 'signatures do not match' error. I don't think that the problem is with the clients as I've tried both postman (for chrome) and a PHP implementation and they both generate the same signature. I have however for interest sake included my client call.
$consumer_key = '87d6d61e87f0e30d8747810ae40041d1';
$consumer_secret = 'f63ed7f7a8899e59d3848085c9668a0d';
$token= 'b9d55b3ec4b755d3fe25d7a781da1dfd044b5155';
$token_secret = '72814e6059441037152eecef2e8559a748b84259';
$timestamp = '1417515075';
$nonce = '9QV4rn';
$version = '1.0';
$method = 'GET';
$url = 'https://localhost/micro/v1/nappi';
try {
$oauth = new OAuth($consumer_key, $consumer_secret, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_URI);
$oauth->enableDebug();
$oauth->disableSSLChecks();
$oauth->setNonce($nonce);
$oauth->setTimestamp($timestamp);
$oauth->setToken($token, $token_secret);
$oauth->setVersion($version);
$oauth->fetch("$url");
$json = json_decode($oauth->getLastResponse());
print_r($json);
}
catch(OAuthException $E) {
print_r($E);
}
I've burned a good couple of hours trying to figure this out, someone please help!
I finally managed to solve it, my .htaccess file had a rewrite rule that was processing a _url parameter for my framework. This parameter was ofcourse being included in the signature that the server generated. I simply instructed OAuth Provider to ignore the the _url parameter in my constructor:
$this->provider->setParam('_url',NULL);,
that was all it took, everything runs perfectly now.
I have this class to send a SOAP-request (the class also defines the header)
class Personinfo
{
function __construct() {
$this->soap = new SoapClient('mysource.wsdl',array('trace' => 1));
}
private function build_auth_header() {
$auth->BrukerID = 'userid';
$auth->Passord = 'pass';
$auth->SluttBruker = 'name';
$auth->Versjon = 'v1-1-0';
$authvalues = new SoapVar($auth, SOAP_ENC_OBJECT);
$header = new SoapHeader('http://www.example.com', "BrukerAutorisasjon", // Rename this to the tag you need
$authvalues, false);
$this->soap->__setSoapHeaders(array($header));
}
public function hentPersoninfo($params){
$this->build_auth_header();
$res = $this->soap->hentPersoninfo($params);
return $res;
}
}
The problem is that there's something wrong with my function and the response is an error. I'd like to find out what content I am sending with my request, but I can't figure out how.
I've tried a try/catch-block in the hentPersoninfo-function that calls $this->soap->__getLastRequest but it is always empty.
What am I doing wrong?
Before I ever start accessing a service programmatically, I use SoapUI to ensure that I know what needs sent to the service, and what I should expect back.
This way, you can ensure the issue isn't in the web service and/or in your understanding of how you should access the web service.
After you understand this, you can narrow your focus onto making the relevant SOAP framework do what you need it to do.
