I use an Infinite Grid, actually all work fine but in the PHP that the store uses I do a request to an external webservice.
This is my Store Load:
myInfGrid.getStore().load({
scope : this,
url : 'download.php',
params : { },
callback: function(records, operation, success) {
if (success) {
// Here a process is done only once time even
// for others automated launched requests
}
}
});
My download.php file contains a curl request to a webservice like below.
Sometimes the WebService takes a very long time to answer.
...
$url = "https://external_webservice";
$params = array('callback' => $callback,
'q' => $query,
'rows' => $rows,
'sort' => $sort,
'start' => $start);
$url .= '?' . http_build_query($params);
$myCurl = curl_init($url);
curl_setopt($myCurl, CURLOPT_RETURNTRANSFER, true);
$fetchResult = curl_exec($myCurl);
curl_close($myCurl);
// HERE my process of $fetchResult content
...
I would like to extract this WebService Curl call and put it only on each callback.
My problem is: I don't know where are others callbacks.
I mean callbacks associated to all requests that are launched automatically by the infinitegrid ?

How to get response and transaction ID as given it API document in Notification URL and on success URL too , please unable to find any help or guide for it ?
The easiest way is to let Payum do notification related job for you. To do so you either:
have to create manually a notification token using Payum's token factory (I am not sure it is present in the Zend module, it is quite old). Use the token as notification_url. Nothing more. Sofort will send a request to that url and Payum does the rest.
Make sure the token factory is passed to a gateway object and later is injected to capture action object. Leave the notification_url field empty and Payum will generate a new one.
use your own url as notification one and add there all the info you need (as a query string). I wouldn't recommend it since you expose sensitive data and once could try to exploit it.
I solved it this way by appending ?trx=-TRANSACTION- with success and notification url and than in response i recieved Transaction id as parameter and later loaded TransactionData with that transactionId . Payum Token way wasn't working for me ! Obiously had to use its config key to create Payum/Sofort/Api isnstance,
REQUEST:
$args = [ 'config_key' => $sofortConfigKey ];
$sofortPay = new Api($args);
// ?trx=-TRANSACTION- will append transacion ID as response param !
$params = [
'amount' => $coupon['price'],
'currency_code' => $coupon['currency'],
'reason' => $coupon['description'],
'success_url' => $successUrl.'?trx=-TRANSACTION-',
'abort_url' => $abortUrl.'?trx=-TRANSACTION-',
'customer_protection' => false,
'notification_url' => '_URL_'.'?trx=-TRANSACTION-',
];
$transactionParams = $sofortPay->createTransaction($params);
return $this->redirect()->toUrl($transactionParams['payment_url']);
RESPONSE:
$args = [ 'config_key' => $configKey ];
$sofy = new Api( $args );
$transNumber = $this->getRequest()->getQuery('trx');
$fields = $sofy->getTransactionData($transNumber);
Took help from API document. Payum documentation is worst. SOFORT API DOC
I am trying to integrate Instamojo Payment Gateway within Chris Kacerguis’ REST Server.
Problem:
The below code:
public function instamojotest_post()
{
$api = new Instamojo\Instamojo(‘abcd1234’, ‘efgh5678’, 'https://test.instamojo.com/api/1.1/');
try {
$response = $api->paymentRequestCreate([
'amount' => 100,
'purpose' => 'New Product Purchase',
'buyer_name' => 'Test User',
'email' => 'testuser#gmail.com',
'phone' => '9876543210',
'redirect_url' => 'http://www.example.com/products_api/validate_payment'
]);
header('Location: ' . $response['longurl']);
} catch (Exception $e) {
$this->response([
'success' => false,
'message' => $e->getMessage()
], 500);
}
}
is not redirecting to the Instamojo Payment Site and no error is being displayed.
It is working fine and redirecting successfully with vanilla CodeIgniter.
Questions:
1) Is it, at all, possible to redirect from within a REST Server Post Method?
2) If the above is possible, then what is wrong with my code?
3) Is there any other way to achieve what I am trying to do?
I found many tutorials on the internet but none of them are using REST Server.
I stumbled accross this question while Googling. I was also facing the same issue and here is how I solved it.
Note: This is not exactly a solution but a work-around. Also I admit that this may not be the best solution out there, but it worked for me.
I returned the payment url from the Rest Server, and redirected to the url from within the Rest Client.
Rest Client Code:
class Test extends CI_Controller
{
public function instamojo_make_payment()
{
$url = "http://www.example.com/products_api/instamojotest";
$params = []; //You will obviously be needing this in real life implementation :)
$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, $url);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_handle, CURLOPT_POST, 1);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $params);
$response = curl_exec($curl_handle);
curl_close($curl_handle);
if ($response['success'])
header('Location: ' . $response['payment_url']);
else
$this->load->view('payment_failed_page');
}
}
Rest Server Code:
class Products_api extends REST_Controller
{
public function instamojotest_post()
{
$api = new Instamojo\Instamojo('abcd1234', 'efgh5678', 'https://test.instamojo.com/api/1.1/');
try {
$response = $api->paymentRequestCreate([
//Make sure to pass these data from the Rest Client
'amount' => 100,
'purpose' => 'New Product Purchase',
'buyer_name' => 'Test User',
'email' => 'testuser#gmail.com',
'phone' => '9876543210',
'redirect_url' => 'http://www.example.com/products_api/validate_payment'
]);
$this->response([
'success' => true,
'payment_url' => $response['longurl']
], 200);
} catch (Exception $e) {
$this->response([
'success' => false,
'message' => $e->getMessage()
], 500);
}
}
}
While giving this answer I assumed that the Api is open. If it is not, then make sure to pass your credentials when making the curl call.
Update
Thanks to #AshwiniChaudhary's comment below, which states that:
REST APIs are not meant for redirection. REST API returns JSON, XML
etc and the receiver takes care of whatever is supposed to be done.
the actual reason behind the fact, "why REST Server is not letting us to perform the redirect", becomes pretty clear.
I am sending a PUT request to an API endpoint I have created. Using jwt, I am able to successfully register and get a token back.
Using Postman, my request(s) work perfectly.
I am using Guzzle within my application to send the PUT request. This is what it looks like:
$client = new \Guzzle\Http\Client('http://foo.mysite.dev/api/');
$uri = 'user/123';
$post_data = array(
'token' => eyJ0eXAiOiJKV1QiLCJhbGc..., // whole token
'name' => 'Name',
'email' => name#email.com,
'suspended' => 1,
);
$data = json_encode($post_data);
$request = $client->put($uri, array(
'content-type' => 'application/json'
));
$request->setBody($data);
$response = $request->send();
$json = $response->json();
} catch (\Exception $e) {
error_log('Error: Could not update user:');
error_log($e->getResponse()->getBody());
}
When I log the $data variable to see what it looks like, this is what is returned.
error_log(print_r($data, true));
{"token":"eyJ0eXAiOiJKV1QiL...","name":"Name","email":"name#email.com","suspended":1}
Error: Could not suspend user:
{"error":"token_not_provided"}
It seems like all data is getting populated correctly, I am not sure why the system is not finding the token. Running the "same" query through Postman (as a PUT) along with the same params works great.
Any suggestions are greatly appreciated!
The token should be set in the authorization header, not as a post data parameter
$request->addHeader('Authorization', 'Basic eyJ0eXAiOiJKV1QiL...');
I am using Soundmanager2 to stream files from soundcloud and display Eq visuals, but I'm having trouble with getting the eqdata when pausing or changing a track.
Shown here
I understand that Flash is unable to access the metadata due to the cross domain policy defined in the "crossdomain.xml" file on soundcloud as seen in this post: (and many others)
How to use SoundManager2 to stream from SoundCloud, and make visualizations?
I realize that I have to resolve the track's stream_url before loading it into sound manager. I'm doing this with an ajax call to a php script that resolves the url (shown below):
var client_id = '866143113772fec9556700f7f88f3abc',
url = 'http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/aries-audio-music/tracks&client_id=';
$.getJSON(url+client_id+'&callback=?', function(playlist){
$.each(playlist, function(index, track) {
//append to playlist
$('<li id="tr-'+track.id+'">' + track.title + '</li>').data('track', track).appendTo('.tracks');
//get resolved stream url
$.ajax({
type: 'GET',
url: 'get_sc_url.php?id='+track.id,
success: function(data) {
console.log(data);
sm2_addtrack(track, data); //create SM2 sound object with resolved url
}
});
});
});
function sm2_addtrack(track, stream_url) {
soundManager.createSound({
id: 'track_' + track.id,
url: stream_url,
usePolicyFile : true,
usePeakData: false,
useWaveformData: false,
useEQData: true,
.....
get_sc_url.php used to resolve stream_url
<?php
require 'include/referrer_check.php';
require 'include/SC_API_KEY.php';
require 'include/API_cache.php';
$track_id = intval($_GET['id']);
$key = get_soundcloud_api_key();
$api_call = 'http://api.soundcloud.com/tracks/'.$track_id.'/stream/?client_id='.$key;
function get_web_page($url) {
/*
* hat tip: http://forums.devshed.com/php-development-5/curl-get-final-url-after-inital-url-redirects-544144.html
*/
$options = array(
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_RETURNTRANSFER => false, // return web page
CURLOPT_HEADER => true,
CURLOPT_NOBODY => true,
CURLOPT_CONNECTTIMEOUT => 5, // timeout on connect
CURLOPT_TIMEOUT => 5, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
CURLOPT_RETURNTRANSFER => true, // return web page
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$content = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );
return $header;
}
$myUrlInfo = get_web_page($api_call);
echo $myUrlInfo["url"];
?>
The result I am getting is something like this:
ec-media.soundcloud.com/Ez0B3lUZjjCR.128.mp3?f10880d39085a94a0418a7ef69b03d522cd6dfee9399eeb9a52200996dfabd3cefb29b7554ff4fd02baab5100d3a070e07d55f6e1eb41808c65398ce84cd496788c171f7e4&AWSAccessKeyId=AKIAJNIGGLK7XA7YZSNQ&Expires=1415223069&Signature=A0qaC1Nr3%2FXw4jwFYMjA%2F98arwI%3D
which plays but gives me no spectrum data at all and I still get the
computeSpectrum() (EQ data) SecurityError: Error #2123
from soundmanager2.
I know for sure that ec-media.soundcloud.com/crossdomain.xml is being downloaded, but I still can't solve this problem.
I think it may be because I'm trying to access the soundcloud crossdomain.xml policy file (which is HTTPS) from a HTTP document. secure="false" is not defined in Soundcloud's crossdomain.xml policy file so it defaults to secure="true", therefore the SWF can not access anything.
I doubt Soundcloud will ever set secure="false" in their crossdomain.xml for obvious reasons (it defeats the purpose of even having HTTPS).
I "think" this is why I get computeSpectrum() (EQ data) SecurityError: Error #2123, but I don't have access to a HTTPS enabled server to test this so I could be wrong.
I made a restful controller that if I send the id the get method receives it. But when I update a form I expect the update method to process but I cant get to the right config for this and after 1 day with this issue I decided to right it down here.
Here the code involved
route in module config:
'activities' => array(
'type' => 'segment',
'options' => array(
'route' => '/activities[/:id][/:action][.:formatter]',
'defaults' => array(
'controller' => 'activities'
),
'constraints' => array(
'formatter' => '[a-zA-Z0-9_-]*',
'id' => '[0-9_-]*'
),
),
),
Head of controller:
namespace Clock\Controller;
use Zend\Mvc\Controller\AbstractRestfulController;
use Zend\Mvc\MvcEvent;
use Zend\View\Model\ViewModel;
use Zend\Form\Annotation\AnnotationBuilder;
use Zend\Form;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\EntityRepository;
use Clock\Entity\Activity;
use \Clock\Entity\Project;
Wich contains the get method:
public function get($id)
{
$entity = $this->getRepository()->find($id);
$form = $this->buildForm(new Activity());
#$form->setAttribute('action', $this->url()->fromRoute("activities", array('action' => 'update')));
$form->setAttribute('action', "/activities/$id/update");
$form->bind($entity);
return array(
"activities" => $entity,
"form" => $form
);
}
That feeds this view:
<h3>Edit activity</h3>
<div>
<?php echo $this->form()->openTag($form);?>
<?php echo $this->formSelect($form->get("project"));?><br>
<?php echo $this->formInput($form->get("duration"));?><br>
<?php echo $this->formInput($form->get("description"));?><br>
<input type="submit" value="save changes" />
<?php echo $this->form()->closeTag($form);?>
</div>
After sending it, I expect update method in activities to take control, but I get:
A 404 error occurred
Page not found.
The requested controller was unable to dispatch the request.
Controller:
activities
EDIT:#DrBeza
This is what i get, that i think (not a master in routes) is right:
Zend\Mvc\Router\Http\RouteMatch Object
(
[length:protected] => 21
[params:protected] => Array
(
[controller] => activities
[id] => 30
[action] => update
)
[matchedRouteName:protected] => activities
)
--
That's it.
Any help?
Quick Fix
The RouteMatch object tries to dispatch ActivitiesController::updateAction but you have defined ActivitiesController::update
That's due to you using a Restful Controller. the Controller::update-Method is specifically tied to PUT-Requests. You need to define an extra method to handle updates via POST-Requests.
I suggest you define ActivitiesController::updateAction, make clear in the docblock it is meant to handle POST-Update requests and refactor both ::updateAction and ::update to share as much common helper-methods as possible for a fast solution.
Common URI Structur information
As a nice information to have when you start developing RESTful applications/APIs:
The ruby community suggests the following url-structure for your resources:
# These are restful
/resource GET (lists) | POST (creates)
/resource/:id PUT (updates) | DELETE (deletes)
# these are just helpers, not restful, and may accept POST too.
/resource/new GET (shows the create-form), POST
/resource/:id/edit GET (shows the update-form), POST
Detailed Problem Analysis
A restful update will be sent by an consumer via PUT, but browsers sending HTML-forms may only send GET or POST requests. You should never use GET to create something. So you have to use POST in a forms-context.
Looking at the problem from an architectural perspective a multitude of possibilities emerge, depending on how big your application is.
For a small application, tight integration (formhandling and API handling in the controller) apply best.
Getting bigger you may want to split up API-Controllers (only restful actions) from Helper-Controllers (form, website handling) which talk to your API-Controllers
Being big (multitude of API-Users) you will want to have dedicated API Servers and dedicated Website Servers (independent applications!). In this case your website will consume the API serverside (thats what twitter is doing). API Servers and Website Servers still may share libraries (for filtering, utilities).
Code Sample
As an educational example I made an gist to show how such a controller could look like in principle. This controller is a) untested b) not production ready and c) only marginally configurable.
For your special interest here two excerpts about updating:
/* the restful method, defined in AbstractRestfulController */
public function update($id, $data)
{
$response = $this->getResponse();
if ( ! $this->getService()->has($id) )
{
return $this->notFoundAction();
}
$form = $this->getEditForm();
$form->setData($data);
if ( ! $form->isValid() )
{
$response->setStatusCode(self::FORM_INVALID_STATUSCODE);
return [ 'errors' => $form->getMessages() ];
}
$data = $form->getData(); // you want the filtered & validated data from the form, not the raw data from the request.
$status = $this->getService()->update($id, $data);
if ( ! $status )
{
$response->setStatusCode(self::SERVERSIDE_ERROR_STATUSCODE);
return [ 'errors' => [self::SERVERSIDE_ERROR_MESSAGE] ];
}
// if everything went smooth, we just return the new representation of the entity.
return $this->get($id);
}
and the editAction which satisfies browser-requests:
public function editAction()
{
/*
* basically the same as the newAction
* differences:
* - first fetch the data from the service
* - prepopulate the form
*/
$id = $this->params('id', false);
$dataExists = $this->getService()->has($id);
if ( ! $dataExists )
{
$this->flashMessenger()->addErrorMessage("No entity with {$id} is known");
return $this->notFoundAction();
}
$request = $this->getRequest();
$form = $this->getEditForm();
$data = $this->getService()->get($id);
if ( ! $request->isPost() )
{
$form->populateValues($data);
return ['form' => $form];
}
$this->update($id, $request->getPost()->toArray());
$response = $this->getResponse();
if ( ! $response->isSuccess() )
{
return [ 'form' => $form ];
}
$this->flashMessenger()->addSuccessMessage('Entity changed successfully');
return $this->redirect()->toRoute($this->routeIdentifiers['entity-changed']);
}
That error message suggests the dispatch process is unable to find the requested controller action and therefore using notFoundAction().
I would check the route matched and make sure the values are as expected. You can do this by adding the following into your module's onBootstrap() method:
$e->getApplication()->getEventManager()->attach('route', function($event) {
var_dump($event->getRouteMatch());
exit;
});
