SoapClient->__construct()

(No version information available, might be only in CVS)

SoapClient->__construct() — SoapClient-Konstruktor

Beschreibung

SoapClient

__construct ( mixed $wsdl [, array $options ] )

Der Konstruktor erzeugt ein SoapClient-Objekt im WSDL- oder nicht-WSDL-Modus.

Parameter-Liste

wsdl

URI der WSDL-Datei oder NULL wenn der nicht-WSDL-Modus verwendet werden soll.

Hinweis: Während der Entwicklung ist es sinnvoll das WSDL-Caching, definiert durch die php.ini Einstellung soap.wsdl_cache_ttl, zu deaktivieren, da sonst Änderungen an der WSDL-Datei erst Wirkung zeigen, sobald die soap.wsdl_cache_ttl erreicht wurde.

options

Ein Array mit Optionen. Optional wenn der WSDL-Modus verwendet wird, sonst müssen die Werte location und uri gesetzt werden, wobei location die URL der Anfrage und uri der Zielnamensraum des SOAP-Service ist.

Die style und use Optionen werden nur im nicht-WSDL-Modus verwendet. In WSDL-Modus werden diese von der WSDL-Datei geliefert.

Die soap_version Option gibt vor, welche SOAP-Client-Version verwendet werden soll (SOAP 1.1 oder SOAP 1.2).

Die Optionen login und password können für HTTP-Authentifizierung verwendet werden. Um eine Verbindung über einen Proxy-Server herzustellen, stehen die Optionen proxy_host, proxy_port, proxy_login und proxy_password zur Verfügung. Für Authentifizierung über HTTPS-Client-Zertifikate nutzen Sie die Optionen local_cert und passphrase.

HTTP-SOAP-Anfragen und -Antworten können mit Hilfe von compression komprimiert werden.

Die Option encoding definiert die intern verwendete Zeichenkodierung. Sie ändert nicht die Kodierung der SOAP-Anfrage selbst (die bleibt immer utf-8), es werden lediglich die Zeichenketten konvertiert.

In der classmap Option können WSDL-Typen auf PHP-Klassen abgebildet werden. Die Option muß ein Array sein mit den WSDL-Typen als Schlüssel und den PHP-Klassennamen als Wert.

Setzen der trace Option (boolean) aktiviert den Gebrauch der Methoden SoapClient->__getLastRequest, SoapClient->__getLastRequestHeaders, SoapClient->__getLastResponse und SoapClient->__getLastResponseHeaders.

Die Option exceptions (boolean) definiert, ob bei SOAP-Fehlern Exceptions vom Typ SoapFault geworfen werden sollen.

Zeitüberschreitung in Sekunden für Verbindungen zu einem SOAP-Service können mit der Option connection_timeout angegeben werden. Diese Option definiert keine Zeitüberschreitung für Dienste mit langsamen Antwortzeiten. Um zu definieren, wie lange auf die Beendung einer Anfrage gewartet werden soll, steht die Einstellung default_socket_timeout zur Verfügung.

Die Option typemap ist ein Array mit Typabbildungen. Jede Abbildung ist ein Array mit den Schlüsseln type_name, type_ns (Namespace URI), from_xml (callback akzeptiert einen String-Parameter) und to_xml (callback akzeptiert einen Objekt-Parameter).

Weitere Optionen sind stream_context, features, cache_wsdl und user_agent.

SoapFault exception: [Client] looks like we got no XML document in <document> has been already mentioned to occur when your server outputs something before <?xml ... > tag. 



For all those having problems with that, and no access to the server code:

This is how to make a proxy that would clean responses for You



<?php

/**

 * Simple class taken from a note by James Ellis [in __doRequest() page of manual]

 */

class Proxy_Client extends SoapClient {

    protected $cacheDocument = "";

    public function __construct($wsdl, $options) {

        parent::__construct($wsdl, $options);

    }



    /**

     * SetCacheDocument() sets the previously cached document contents

     */

    public function SetCacheDocument($document) {

        $this->cacheDocument = $document;

    }



    /**

     * __doRequest() overrides the standard SoapClient to handle a local request

     */

    public function __doRequest() {

        return $this->cacheDocument;

    }

}



//put this code in your function or wherever You have all required variables set



$client = new SoapClient($wsdl_url,$settings_array);

$void=$client->$method($params);  //call this to get response from server

        

$response_string=$client->__getLastResponse();

        

//this part removes stuff

$start=strpos($response_string,'<?xml');

$end=strrpos($response_string,'>');    

$response_string=substr($response_string,$start,$end-$start+1);



//get your proxy prepared

$proxy = new Proxy_Client($wsdl_url,$settings_array);

//and fill it with the server's response

$proxy->SetCacheDocument($response_string);



$and_finally_the_result_is=$proxy->$method($params);



print_r($and_finally_the_result_is); //this allows You to see what's there



?>



$method is the method's name eg. $method='getVersion';

$params - typical params for a soap method

When using classmap option to map the SOAP results to a class, the constructor

of the object you've mapped to is not called. 



$client = new SoapClient("url_to_wsdl", 

   array('classmap' => array('contact' => "Contact"));



$params = array("1");



$contact = $client->__soapCall("get_contact", $params);



Expected result:



A contact object that has properties initialized (i.e. db connections,

....).



Actual result:



A contact object without the properties.



Thanks for your help.

The same goes for using an SSL client certficate, the SoapClient will only present the certificate on the actual remote call, not when getting the WSDL. The workaround is the same as above. HttpRequest works as expected.

The "cache_wsdl" option takes constants like WSDL_CACHE_NONE or WSDL_CACHE_DISK that are listed on the "SOAP constants" page -> /manual/en/soap.constants.php

A note regarding boolean values that may seem obvious on reflection but could be a gotcha for some:



Seeing a SOAP request example with <SomeBooleanParam>true</SomeBooleanParam> may lead you to pass in string "true" or "false" as the parameter, which is incorrect - the correct method is to use boolean data types.



<?php

$client = new SoapClient($wsdl,$options);

$method = "DoSomething";

$params = new stdClass;



$params->SomeBooleanParam = TRUE;

$client->$method($params);

/**

 simplified request snippet would be

 <SomeBooleanParam>true</SomeBooleanParam>

**/



//this will also be correct, but not for the right reasons:

$params->SomeBooleanParam = "true";

$client->$method($params);

/**

 simplified request snippet would be

 <SomeBooleanParam>true</SomeBooleanParam>

**/



//this is where you may be wondering what is going on

$params->SomeBooleanParam = "false";

$client->$method($params);

/**

 simplified request snippet would be

 <SomeBooleanParam>true</SomeBooleanParam>

**/



//you need to do this instead

$params->SomeBooleanParam = FALSE;

$client->$method($params);

/**

 simplified request snippet would be

 <SomeBooleanParam>false</SomeBooleanParam>

**/

?>



Hope that helps!

If you want to use compression there is a missing parameter in the example above:



<?php

$client = new SoapClient("some.wsdl", 

  array('compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 5));

?>



If you use SOAP_COMPRESSION_GZIP you have to add the compression level. Otherwise it will not compress the request. Took me some hours ;)

Oops!



I have written the wrong exception message in my last post.



The correct exception is:



SoapFault exception: [Client] looks like we got no XML document in <document>

giosh94mhz

If you get the following exception:



'Cannot open the XML file: the file is not well-formatted!'



PHP files of your SOAP-server contains syntax-error (probably).



If everything looks ok, try to remove EVERY blank-space and new-line outside the <?php ... ?> tag... this should save you an headache!

As noted in the bug report http://bugs.php.net/bug.php?id=36226, it is considered a feature that sequences with a single element do not come out as arrays. To override this "feature" you can do the following:



$x = new SoapClient($wsdl, array('features' =>

SOAP_SINGLE_ELEMENT_ARRAYS));

When using classmap to map the SOAP results to a class, the constructor of the object you've mapped to is _not_ called.  This applies to the PHP5 __construct() and the PHP4 ClassName() constructors.

I kept having a problem using an HTTP proxy with SOAP. The proxy_port parameter has to be an integer, ie. "proxy_port"=>"80" won't work, you'll have to use "proxy_port"=>80.

If you're using CLI and there are multiple IP addresses available for outgoing SOAP-requests, try this "secret" to set outgoing IP:



e.g. for local IP 10.1.4.71:



$opts = array('socket' => array('bindto' => '10.1.4.71:0'));

$context = stream_context_create($opts);

$client  = new SoapClient(null, array('location'=>'http://...','uri' => '...','stream_context' => $context));



You can also set other options for the stream context, please refer to this page:



Appendix M: http://www.php.net/manual/en/wrappers.php

If you connect to a SoapServer, that has been created with session persistence, you can access the server's session id via SoapClient->_cookies[<session_id_name>][0]. This property becomes available after your first client method call.



I have only tested this with session.use_cookies=1.

When using HTTP basic authentication, PHP will only send the credentials when invoking the service, not when fetching the WSDL. 



To solve this, one needs to fetch the WSDL manually (or using PHP, of course!) and store it on the file system. Obviously, the first parameter for SoapClient(..) then needs to refer to that local copy.



Alternatively, the user annotations at http://nl3.php.net/manual/en/ref.soap.php state that one could encode the login and password into the URL as well.

As of version 5.0.4 you can now dynamically change your location even if you're using a wsdl



<?php



$client = new SoapClient("http://some.host.net/wsdl/somefile.wsdl",array(

    "location" => 'myurl.com'));



?>



notice you can now use the "location" key. 

This means you can have the same wsdl file not define a location until runtime which is great if you have a development test site or if you distribute your files to other companies. 

Prior to this change you would have to ship a custom wsdl file to every client you had with their location hardcoded.

Brian Grayless

Using a WSDL file is the way to go, however, for my particular application, the LOCATION:PORT needed to be dynamic so that my SOAP clients would be able to call a different service based on the client domain.



If you are using a WSDL, SoapClient() requires a URL direct to an actual URL and does not let you use a PHP file that outputs the dynamic WSDL XML in its stead. So, I ended up making a separate WSDL for each possible service needed and had to maintain them all if the service description changed.



Finally, after some fiddling, I was able to create a PHP page with the proper Mime type headers so that I could then trick SoapClient() to think that it was being passed a file with a ".wsdl" extension.



Example:



<?php



// filename: wsdl.php



header('Content-Type: application/xml; charset=UTF-8');

header('Content-Disposition: attachment; filename="filename.wsdl"');



$wsdl = 'path/wsdl_name.wsdl';



// read in file

$handle = fopen($wsdl, "r");

$wsdl_xml = fread($handle, filesize($wsdl));

fclose($handle);



// put code here to replace url and port in xml



echo $wsdl_xml;



?>



Now, in order to make this work, you can't just call a relative path to the file. I believe it has to go through Apache to properly set the mime type headers, etc... So you would use a full "http://....." address as the path to the wsdl.php file.



<?php



//... somewhere in your soap client code



$wsdl_loc = "http://yourdomain.com/wsdl.php";



$soap_client = new SoapClient($wsdl_loc, $client_param_array);



?>



Another, perhaps not so clean, way of achieving this would be to modify your .htaccess file in the directory where your WSDL file exists to force ".wsdl" files to run through the PHP engine. Add the following to your .htaccess:



AddType application/x-httpd-php .php .wsdl



You can then put dynamic PHP code snippets in your *.wsdl files to change whatever values you need to.



There are pros and cons to each solutions. The Mime solution probably taxes the system more as it has to read the file in every time a soap request is made. The htaccess solution makes it so you have to depend on either a modified .htaccess or Apache conf file.



Perhaps if you set the "soap.wsdl_cache_enabled", using ini_set(), to 1 (default), the caching will make it so it doesn't read the file every time for the Mime solution.
