Not getting PHP soap api resonse on server for randome time - php

I am facing weired issue for soap api on my development and production server.
We have itegrated bunch of 3rd party soap API which are fetching details from 3rd party and displaying data on our site.It is working very well.Most of time APIs working perfectly.It happen in some random period of time soap api response becomes null and we get 0 in api response.We had discuss with 3rd party service about that issue and they had replied after check their log that, they are providing each and every response raising from our end.Can any one guide me does it code base issue or server base issue? and how to get rid of it as it is loosing client's business because of it.
Below are functinal of our WSDL calling from PHP soap function.
We send request for validation to 3rd party api, and store temp. security key on our server. And use this security key as token for each api.while this random glitch happen we does not get any response in that case. below is my soap code for call wsdl api.
$wsdl = 'URL';
$options = array(
'cache_wsdl' => 0,
'trace' => 1,
'stream_context' => stream_context_create(array(
'ssl' => array(
'verify_peer' => 0,
'verify_peer_name' => 0,
'allow_self_signed' => 1
)
)));
$soapCall = new SoapClient($wsdl,$options);
try {
$response = $soapCall->__soapCall("API_FUNCTION", array($params));
//Save records to log
$requestParamLogs = $soapCall->__getLastRequest();
$responseParamLogs = $soapCall->__getLastResponse();
}
catch (SoapFault $e) {
$requestParamLogs = $soapCall->__getLastRequest();
$responseParamLogs = $soapCall->__getLastResponse();
}
While we are facing such random issue on our deployment and production server, we do not get such issue in local server.
Note: We are getting response of each API in postman without issue all time.
I have tried google for it, but do not get anything suitable solution for my case so anyone having an idea, please guide me.

PHP SOAP-ERROR: Parsing Schema: element already defined When Connecting to D365 WSDL

I am connecting to dynamics 365. It used to work perfectly, i curl to get the token then i use it as an authorization header along with php soapclient and it works, i connect i create a client and i can call my methods.
All of a sudden it decided not to work, and where it used to connect as SOAP 1.1 now it enforced SOAP 1.2
After changing from SOAP 1.1 to SOAP 1.2 ( because I got the error of binding mismatch where it said expecting application/soap+xml and text/xml was found ) So I changed versions and that error disappeared and got replaced with ERROR Fetching HTTP Headers.
That error got stuck for the longest time, people suggested to increase timeout but i put it as high as 500 800 5000 all the same.
Then all of a sudden, it started giving me SOAP ERROR Parsing schema element already defined. I did not change my code, i played for awhile with the headers but to no avail, I even removed the authorization header just to see what is going on and that did nothing i kept getting the same error.
SOAP-ERROR: Parsing Schema: element 'http://schemas.datacontract.org/2004/07/Microsoft.Dynamics.Ax.Xpp:XppObjectBase' already defined [string:Exception:private]
everytime I try to connect I get different kind of parsing schema error even though i am not changing anything in my code:
SOAP-ERROR: Parsing Schema: element 'http://schemas.microsoft.com/2003/10/Serialization/:anyType' already defined [string:Exception:private]
and another
SOAP-ERROR: Parsing Schema: element 'http://schemas.datacontract.org/2004/07/Microsoft.Dynamics.AX.KernelInterop:ProxyBase' already defined [string:Exception:private]
and then sometimes it does get through for a second but with fetching http header error again..
so i can not create a client instance anymore now..
where before i was able to create a client instance but i get an error when I call the method of "Error Fetching HTTP Headers"
something is definitely not stable because my errors are not one.
now some stated the wsdl could be faulty, but this is microsoft and the person i am in contact keeps saying he can not doing anything about it.
Help is this a PHP problem or a dynamics problem or wsdl custom made problem .
And how to solve this.
Thank you.
UPDATE
I'm sorry I mentioned earlier it is Dynamics AX , it turns out it is Dynamics 365 D365. I will keep dynamics ax tag in case it helps someone who needs the solutions provided.
UPDATE
Following is the connection code I am using:
function getAuthenticationHeader()
{
//Each variable has the values for our server
//resource
$appResource = urlencode($appADResource);
//clientID
$appClientID = urlencode($appADClientId);
//appSecret
$appSecret = urlencode($appADSecret);
//username
$appUserID = urlencode($appUserID);
// Password
$appUserPassword = urlencode($password);
// Construct the body for the STS request
$authenticationRequestBody = 'resource='.$appResource.'&client_id='.$appClientID.'&client_secret='.$appSecret.'&grant_type=password&username='.$appUserID.'&password='.$appUserPassword.'&scope=openid';
//Using curl to post the information to STS and get back the authentication response
$ch = curl_init();
// set url
$stsUrl = 'https://login.microsoftonline.com/'.$appTenantId.'/oauth2/token';
curl_setopt($ch, CURLOPT_URL, $stsUrl);
// Get the response back as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Set the parameters for the request
curl_setopt($ch, CURLOPT_POSTFIELDS, $authenticationRequestBody);
// By default, HTTPS does not work with curl.
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// read the output from the post request
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
// decode the response from sts using json decoder
$tokenOutput = json_decode($output);
return $tokenOutput->{'token_type'}.' '.$tokenOutput->{'access_token'};
}
try
{
//WSDL Link
$url = "https://urlToOurServer/services/webservice?wsdl";
$authorizationToken = getAuthenticationHeader();
$context = stream_context_create(array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
),
'https' => array(
'curl_verify_ssl_peer' => false,
'curl_verify_ssl_host' => false
),
'http' => array(
'header' =>'Authorization: '.$authorizationToken
)
));
//Create array of Soap Options
$arrOpt = array(
"soap_version" => SOAP_1_2,
"cache_wsdl" => WSDL_CACHE_NONE,
"exceptions" => true,
'trace' => true,
'encoding' => 'UTF-8',
'stream_context' => $context
);
}catch(Exception $e)
{
print_r($e);
}
I also found this in my wsdl
<sp:IssuedToken sp:IncludeToken="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702/IncludeToken/AlwaysToRecipient">
<sp:RequestSecurityTokenTemplate>
<trust:TokenType xmlns:trust="http://docs.oasis-open.org/ws-sx/ws-trust/200512">

</sp:RequestSecurityTokenTemplate>

How can I connect to SAML for Token ?
If everything is pretty much the same, but it's not working, the first thing to do is rule out the most basic AX issues. These may not solve your issue but will be a good first step.
now some stated the wsdl could be faulty, but this is microsoft and the person i am in contact keeps saying he can not doing anything about it.
Whomever that person is, you need to confirm they've done the following:
Confirm the environment and specifically the CIL is fully compiled. Do a full AXBuild and a full CIL to be sure during non-business hours and ensure the output is good. It's basically saying "recompile everything".
Refresh the WCF configuration in the client configuration you are using to connect to AX. This client configuration may be a *.axc file or it may just be the active one. Also refresh the business connector WCF. This is separate and may be what you are using to connect to AX. This is what most people are talking about.
Here's a little article that talks about creating a configuration, but I'll discuss below.
An AX client configuration ultimately is a bunch of text. It's either stored in an .axc file or stored in the registry in a few locations. The Business Connector client config may be the one that is getting missed in your scenario.
If you follow the link above and create a new .axc configuration file and ensure you've clicked "Refresh Configuration" before exporting, when you open the file up in Notepad, you'll see wcfconfig and a bunch of XML following it. That XML is what you're trying to get updated. Creating a new AXC here is just an exercise to help you understand what it is. You can delete the file after you're done looking.
Now, you've basically created a specific configuration file, but that doesn't mean anything is using it. If you call AX32.exe it will default to the one that is loaded in that config screen. Using a file is a way to very specifically choose one. Your code is probably using a specific AXC somewhere that needs either replaced or refreshed OR it's using one that's saved in this window:
It is very likely it is using one of the two that are saved in that configuration window. When you refresh in that window, it ultimately saves the WCF XML in the windows registry on the machine that is hosting the client and/or the AOS in subfolders in HKLM\SOFTWARE\Microsoft\Dynamics\6.0\Configuration. The key(s) is wcfconfig paired with wcfconfigversionid, which just stores a GUID to see if it's up-to-date.
When I say two, I mean most people don't even bother to look at the Business Connector AXC. It's what is highlighted in yellow in my image, and you need to specifically choose and refresh it. This could be important for you. In my image, I do not have it chosen. You need to drop the menu down and choose it.
On a dev machine, you can just clear both of those keys and refresh and you should see whatever configuration you're working on update.
This is a long post, but it's important to rule this part out first. If you have someone who's reasonably experienced administering AX they should know how to ensure these are refreshed.
Since you're saying this is not Dynamics AX, but one of the Dynamics 365 versions. The AX version used to be called Dynamics 365 for Finance and Operations Enterprise Edition but they've changed the licensing/naming again, so I don't even know what it's technically called. Most people call it Dynamics 365 for Operations or some variant.
Either way, you should test the service following the below method. We would need to see more information about the service details and call, so following the below is most likely best.

Shopify Webhooks work in testing but not in practice

I'm having some problems with my Shopify 'orders/paid' webhook that I install onto the users store via the Shopify SDK (using a PHP wrapper: https://github.com/phpclassic/php-shopify). Anyways, I create the webhook like so:
$shop = $this->request->getVar('shop'); // Get Shopify store URL
// Get access token for store
$config = array('ShopUrl' => $shop, 'ApiKey' => 'xxx', 'SharedSecret' => 'xxx');
\PHPShopify\ShopifySDK::config($config);
$accessToken = \PHPShopify\AuthHelper::getAccessToken();
// Keep track of access_token for SDK calls and authenticate to store for webhook creation
$addToken = $this->Stores->addAccessToken($shop, $accessToken);
$config = array('AccessToken' => $accessToken, 'ShopUrl' => $shop);
$shopify = new \PHPShopify\ShopifySDK($config);
// Create orders/paid webhook
$orderPaidHook = array('topic' => 'orders/paid', 'address' => 'https://api.autoloapp.com/webhook/create', 'format' => 'json');
try {
$webhooks = $shopify->Webhook->post($orderPaidHook);
}
This code as far as I can tell works, using print_r($webhooks) gives me a valid Webhook that has (in theory) been installed on to the store. However, when an order is actually paid for on the store I DO NOT get a message.
Using the "Test Webhook" settings under "Notification" in the Shopify Admin my webhook works perfectly. Using PostMan to simulate a webhook call works perfectly.
The code to process the webhook looks like this:
$headers = getallheaders();
$topic = $headers['X-Shopify-Topic'];
$storeName = $headers['X-Shopify-Shop-Domain'];
if ($topic == 'orders/paid') {
// Do some stuff, insert row into database
}
Again, when I use PostMan or the built-in "Test Webhook" setting for Shopify the row in my database gets created just fine. When I do it with a real webhook nothing happens. I'm not sure why this is happening, as far as I know all the headers should be the same. Do I need to verify the webhook in some way?
For reference I'm using CodeIgniter 4.0, PHP 7.0, and the newest version of the Shopify SDK.
I found this note on Shopify's Docs: "Note that if you are using a Rack based framework such as Ruby on Rails or Sinatra the header you are looking for is HTTP_X_SHOPIFY_HMAC_SHA256". With my current set-up I should still be using X-Shopify-Shop-Domain instead of HTTP_X_Shopify_Shop_Domain correct? Any help greatly appreciated!
So I finally figured out that for some reason the 'orders/paid' webhook wouldn't work for me in "production environments" despite working fine in my test environments. Simply changing the topic to 'orders/create' resolved my problem.

WS-Security, and how to Authenticate

Documentation of the service, says I need to use WS-Security.
From they support, i got a p12 file, which I should be using.
What I did so far
I ran up SoapUI application, configured it, added wsdl etc, and got message
<faultstring>These policy alternatives can not be satisfied: (...)</faultstring>
So I found I need to add basic Auth to the request. And i got my proper answer.
What I need now
I need to use this to SOAP requests, on my PHP application.
First, i changed p12 file into pem, and tried :
$soapClient = new SoapClient('https://int.pz.gov.pl/pz-services/tpSigning?wsdl',
array('location' => 'https://int.pz.gov.pl/pz-services/tpSigning?wsdl',
'trace' => 1,"exceptions" => 1,
'local_cert'=>'path/cert_file.pem',
'passphrase'=>'cert_password'
));
But I am still getting same fail message about policies not being satisfied:
These policy alternatives can not be satisfied:
{http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702}AsymmetricBinding: Received Timestamp does not match the requirements
{http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702}X509Token: The received token does not match the token inclusion requirement
{http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702}SignedParts: Soap Body is not SIGNED in (...)
Help?
Is it even possible with just PHP? I tried several solutions, found some class extending SoapClient (using user/password, not p12/pem file), found even solution in c# (which I am too ready to use if that's what I need to do - sending xml to c# with WebSocket, and sending it back to browser), but non of those worked.
Changing the cert into pem format is the right way. The native PHP soap client class can not handle p12 certs. Have you tried the following?
try {
$oClient = new SoapClient(
'https://int.pz.gov.pl/pz-services/tpSigning?wsdl',
[
'authentication' => SOAP_AUTHENTICATION_DIGEST,
'exceptions' => true,
'local_cert' => dirname(__FILE__) . 'mycert.pem',
'passphrase' => 'my_passphrase',
'trace' => true,
]
);
} catch (SoapFault $oSoapFault) {
echo "<pre>";
var_dump($oSoapFault);
echo "</pre>";
}
The PHP soap client class uses SOAP_AUTHENTICATION_BASIC by default. Perhaps the DIGEST auth is the right way? Normally the cert includes all the data.
You don 't need the location option. The location option is just required, when using non-wsdl conversation with target namespace as uri option without a direct wsdl file.
And always keep in mind: What works with SoapUI isn 't supposed to run with the native PHP client. ;)

Unable to request _GET_SELLER_FEEDBACK_DATA_ report from Amazon MWS Reports API?

I am using Amazon MWS Reports API to get customer's feedback using "_GET_SELLER_FEEDBACK_DATA_" report type.
But unfortunately it says "report status cancelled". Using Scratchpad to request this report it works fine.
The following is my code:
$report_type = "_GET_SELLER_FEEDBACK_DATA_";
$config = array(
'ServiceURL' => "https://mws.amazonservices.co.uk",
'ProxyHost' => null,
'ProxyPort' => -1,
'MaxErrorRetry' => 3,
);
$service = new MarketplaceWebService_Client($AWS_ACCESS_KEY_ID, $AWS_SECRET_ACCESS_KEY, $config, $APPLICATION_NAME, $APPLICATION_VERSION);
$marketplaceIdArray = array("Id" => array($MARKETPLACE_ID));
//Sends Report Request
$request = new MarketplaceWebService_Model_RequestReportRequest();
$request->setMarketplaceIdList($marketplaceIdArray);
$request->setMerchant($MERCHANT_ID);
$request->setReportType($report_type);
$request->setReportOptions('ShowSalesChannel=true');
$request->setStartDate(new DateTime('-90 Days', new DateTimeZone('UTC')));
$report_request_id = invokeRequestReport($service, $request);
The Reports API class methods invokeReportRequest(), invokeGetReportRequestList(), invokeGetReportList() and invokeGetReport() are unchanged by me.
Amazon accepts your report request, but then refuses to actually produce one. I'm not sure if there is a way to get any meaningful error message out of MWS, but from past experience, this kind of thing happens when your request is technically valid but has a logical error of some sorts (e.g. You submit an XML file that validates against the XSD but contains prices for items that are not part of your inventory)
I haven't tested this, but looking at the API docs (MWS Reports API Reference pg. 46), it seems that ShowSalesChannel is not a valid ReportOption for _GET_SELLER_FEEDBACK_DATA_ reports (it seems to be allowed only in order reports, and getting seller feedback does not support any ReportOption). So please try and remove
$request->setReportOptions('ShowSalesChannel=true');
from your code and see what happens.

PHP non blocking soap request

After a user signs up on my website i need to send a soap request in a method that is not blocking to the user. If the soap server is running slow I don't want the end user to have to wait on it. Is there a way I can send the request and let my main PHP application continue to run without waiting from a response from the soap server? If not, is there a way to set a max timeout on the soap request, and handle functionality if the request is greater than a max timeout?
Edit:
I would ideally like to handle this with a max timeout for the request. I have the following:
//ini_set('default_socket_timeout', 1);
$streamOptions = array(
'http'=>array(
'timeout'=>0.01
)
);
$streamContext = stream_context_create($streamOptions);
$wsdl = 'file://' . dirname(__FILE__) . '/Service.wsdl';
try{
if ( file_get_contents( $wsdl ) ) {
$this->_soapClient = new SoapClient($wsdl,
array(
'soap_version' => SOAP_1_2,
'trace' => true,
'stream_context' => $streamContext
)
);
$auth = array('UserName' => $this->_username, 'Password' => $this->_password);
$header = new SoapHeader(self::WEB_SERVICE_URL, "WSUser", $auth);
$this->_soapClient->__setSoapHeaders(array($header));
}//if
}
catch(Exception $e){
echo "we couldnt connect". $e;
}
$this->_soapClient->GetUser();
I set the timeout to 0.01 to try and force the connection to timeout, but the request still seems to fire off. What am I doing wrong here?
I have had the same issues and have implemented solution !
I have implemented
SoapClient::__doRequest();
To allow multiple soap calls using
curl_multi_exec();
Have a look at this asynchronous-soap
Four solutions:
Use AJAX to do the SOAP -> Simplest SOAP example
Use AJAX to call a second PHP file on your server which does the SOAP (best solution imo)
Put the SOAP request to the end of your PHP file(s) (not the deluxe solution)
Use pcntl_fork() and do everything in a second process (I deprecate that, it might not work with every server configuration)
Depending on the way you implement this, PHP has plenty of timeout configurations,
for example socket_set_timeout(), or stream_set_timeout() (http://php.net/manual/en/function.stream-set-timeout.php)
