PHP Websample

ArielRauch · Post by **ArielRauch** » Sun Sep 07, 2014 8:28 am

Hi,

I am not sure if this is the right place to post this problem - feel free to route me:)

I have installed the web services module and I am trying to get the sample working but I am receiving "connection failed" after entering the credentials. My setup is as follows:

Switch 12 on:

1. Windows 2008R2 Standard

2. HP Server (12 GB RAM)

Web Sample:

1. same server

2. IIS7.5

3. php 5.6

4. Enabled:

a. openssl

b. curl

c. soap

5. phpinfo is working - of course

Switchclient is connecting without problems

Any suggestions how I can debug to understand what is the problem?

Thanks

Ariel

Here's a minimal PHP example I wrote last year.

<?php

error_reporting(E_ALL ^ E_DEPRECATED);

require 'SOAP/Client.php';

$protected_url = "https://localhost:51008";

$my_cert_file = "cacert.pem";

$user = "USERNAME;EN";

$pass = "PASSWORD";

try {

$client = @new SoapClient("butterfly.wsdl",

array( 'local_cert', $my_cert_file,

'trace' => true,

'exceptions' => true,

'login' => $user,

'password' => $pass

));

$client->__setLocation($protected_url);

} catch (Exception $e) {

echo $e->getMessage();

die();

}

$connectReply = $client->CheckConnect();

$credentials = array('login' => $user, 'password' => $pass);

$loginReply = $client->CheckUserNameAndPass($credentials);

$flowsReply = $client->GetFlowList();

#print_r($flowsReply);

foreach ($flowsReply->flowList as $flowId) {

$flowParms = array('flowId' => $flowId);

$flowNameReply = $client->GetFlowName($flowParms);

$flowStateReply = $client->GetFlowState($flowParms);

if ($flowStateReply->FlowState == 3) {

echo $flowId . " " . $flowStateReply->FlowState . " " . $flowNameReply->flowName . "n";

$submitPtsReply = $client->GetSubmitPoints($flowParms);

if (is_array($submitPtsReply->submitPoints)) {

foreach ($submitPtsReply->submitPoints as $submitPtId) {

$submitPtParms = array('flowId' => $flowId, 'submitPointId' => $submitPtId);

$submitPtNameReply = $client->GetSubmitPointName($submitPtParms);

echo " " . $submitPtId . " " . $submitPtNameReply->submitPointData->name . "n";

}

} else {

$submitPtParms = array('flowId' => $flowId, 'submitPointId' => $submitPtsReply->submitPoints);

$submitPtNameReply = $client->GetSubmitPointName($submitPtParms);

print_r($submitPtNameReply);

echo " " . $submitPtsReply->submitPoints . " " . $submitPtNameReply->submitPointData->name . "n";

}

}

}

die();

?>

Hi,

thank you very much for your help!

when running the code I receive an 500 internal error.

I am not a PHP programmer but you require in the code: "SOAP/client.php" which I do not have.

Every advice how to progress would be great.

Did you put the files of the PHP in the document root folder of the PHP server? You will find the location of that document root folder in the phpinfo. In the settings subfolder of the sample there is a settings.php that also specifies the subfolder (if any) the sample is located in, so you may have to change that.

That's going to be a problem. Webservices is a complex topic and can't be solved by cut-n-paste programming. I recommend that you hire an experienced PHP developer.

dkelly: I am not offended especially not as I know you inspected my LinkedIn profile:)

freddy: Yes, I put it in the root folder and I adjusted the parameters in settings.php

I assume it is an installation/permission issue

Just curious -- what does the web services module do? I've done a lot with PHP's SoapClient and it's really great. I did some stuff with Switch in Javascript using their Soap class which turned out all right but it would be great if I could roll in my PHP code into Switch somehow.

The easiest way to think about Webservices is that you could write your own SwitchClient application using it.

Webservices module enables a developer to connect to a running Switch server, inquire about flows, jobs, etc and submit jobs to submitpoints. Webservices uses an older SOAP protocol. It doesn't support latest SOAP version nor does it support REST.

Gabriel: The Web services module actually offers the same functionality as the SwitchClient.

It means that you can implement a web application which enables remote users (like your customers) to upload and monitor jobs. It is - if I understand correctly - an open solution to what Connect and Connect all is used today.

I have made some more research and debugging and got the following error message:

Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host in C:inetpubwwwrootincludelibSwitchClientService_v4.0.php:1234 Stack trace: #0 [internal function]: SoapClient->__doRequest(‘__soapCall(‘CheckUserNameAn…’, Array, Array) #2 C:inetpubwwwrootincludelibSwitchClientService_v4.0.php(1281): switchclientService->CheckUserNameAndPass(Object(switchclientCheckUserNameAndPass)) #3 C:inetpubwwwrootincludecheckloginfromswitch.php(33): switchclientService->isAdminCredentials() #4 {main} thrown in C:inetpubwwwrootincludelibSwitchClientService_v4.0.php on line 1234

Any ideas?

Did you change

$protected_url = "https://localhost:51008";

to point to your Server server? Is Switch server running?

ArielRauch · Post by **ArielRauch** » Mon Sep 08, 2014 5:21 pm

Hi,

in the code you sent me I defined the $protected_url and yrs switch server is running. The switchclient is connecting without any problems.

The code you sent me references SOAP/Client.php which does not reside on my server. It is part of the pear package which is not installed.

In the sample code from enfocus the php file is not referred.

Do I need this package?

SOAP/Client.php is standard part of PHP distribution. My copy is located in /opt/local/lib/php/SOAP/Client.php

Shouldn't matter. What PHP distribution did you install?
