执行使用php创建的web服务

Question

hello I have a webservice created in Progress, and I need to create a client in php.

I have this example created in Progress to create the client:

//connect 
CREATE SERVER hWebService.
hWebService:CONNECT("-WSDL'http://myip.com:8080/wsa/wsa1/wsdl?targetURI=urn:ws_hecam'").

 //create a handle

RUN ws_hecam SET hws_hecam ON hWebService.

  //execute the method

RUN p10wsCosLPa1 IN hws_hecam (input user, input password, input XMLin, output XMLout)

This is what I have in php:

$client = new SoapClient(null, array('location' => "myip.com:8080/wsa/wsa1/wsdl/ws_hecam.wsm",
                                 'uri'      => "myip.com:8080/wsa/wsa1/wsdl?targetURI=urn:hecam"));

try{
   $client->__soapCall("p10wsCosLPa1", array("user", "password", "xml"), NULL,
                NULL, $output);
   print_r($output);

} catch(SoapFault $exception){
   print_r("Got issue: <br/>");
   var_dump($exception);
}

I have this error:

Got issue:
object(SoapFault)#2 (9) { ["message":protected]=> string(25) 
"Could not connect to host" ["string":"Exception":private]=> string(0) ""
["code":protected]=> int(0) ["file":protected]=> string(41) "/var/www/telematel/ejecutarWebService.php"

 ["previous":"Exception":private]=> NULL 
 ["faultstring"]=> string(25) "Could not connect to host" 
 ["faultcode"]=> string(4) "HTTP" } Array ( ) 

How can I solve this?

Answer 1

Have you verified that the service is running?

1) Does the Progress version work? You can save the answer in a local xml like this (replace the filename with a location of your choice):

XMLout:SAVE("FILE", "/tmp/localfile.xml", TRUE).

Now open that file. Is it there? Does it contain anything? If it does you know for sure that you have a service up and running. Otherwise you will have to start troubleshooting the service.

2) If it doesn't exist or is empty (and shouldn't be): did you receive any errors running the code? If so: post them here! No errors and service seemingly running --> the problem must be in (or around) the php. Could be a problem with data formats not being compatible. I'm not skilled in php but I would check for "wsdl to php" or "wsdl analyzer for php" on Google so you can make sure you have correct data formats.
