SoapHeader::SoapHeader — SoapHeader constructor
Constructs a new SoapHeader object.
The namespace of the SOAP header element.
The name of the SoapHeader object.
A SOAP header's content. It can be a PHP value or a SoapVar object.
Value of the mustUnderstand attribute of the SOAP header element.
Value of the actor attribute of the SOAP header element.
Beispiel #1 SoapHeader::SoapHeader() example
<?php
$client = new SoapClient(null, array('location' => "http://localhost/soap.php",
'uri' => "http://test-uri/"));
$client->__soapCall("echoVoid", null, null,
new SoapHeader('http://soapinterop.org/echoheader/',
'echoMeStringRequest',
'hello world'));
?>
Just for you to know, when trying to get header -using SOAP- input you should do this:
<?php
//SOAP Server class constructor
$xml = file_get_contents('php://input');
/*
In $xml you'll have all the XML input and then with a simple Regexp you can get Usr & Pass when you need to validate a Web Service using SOAP
*/
?>
Hope it helps someone as it helped me :D
I was unable to connect to .net using any of the previous notes. I found out that the easiest way is the one that works. Everyone is trying to use soapvar . but you dont need to.
$ns = 'http://blabla.com/Services/Services';
$AuthHeader = new AuthHeader($LoginResponse);
$header = new SoapHeader($ns,"AuthHeader", $AuthHeader,false);
$this->soapClient->__setSoapHeaders(array($header));
my header was suppose to look like this
<soapenv:Header>
<ns1:AuthHeader>
<ns1:SessionKey>xxxx</ns1:SessionKey>
<ns1:SessionRole>xxxxx</ns1:SessionRole>
<ns1:UserType>xx</ns1:UserType>
<ns1:UserName>xxx</ns1:UserName>
</ns1:AuthHeader>
</soapenv:Header>
so my AuthHeader is just a simple class
class AuthHeader
{
var $SessionKey;//string
var $SessionRole;//string
var $UserType;//string
var $UserName;//string
function __construct($LoginResponse)
{
$this->SessionKey = $LoginResponse->LoginResult->SessionKey;
$this->SessionRole = $LoginResponse->LoginResult->SessionRole;
$this->UserType = $LoginResponse->LoginResult->UserType;
$this->UserName = $LoginResponse->LoginResult->UserName;
}
}
The important lesson here is the when you build your header you can use a normal class. It does not need to be a soapvar
To do headers (the raw way):
// Setting "trace" will allow us to view the request that we are making, after we have made it.
$objClient = new SoapClient("http://www.somewhere.com/wsdls/some.wsdl", array('trace' => true));
// These parameters satisfy this specific remote call.
$arrParameters_Login = array('username' => 'username', 'password' => 'password', 'company' => 'Company');
// Invoke the remote call "login()".
$objLogin = $objClient->login($arrParameters_Login);
// Grab session ID that this remote call will provide.
$strSessionID = $objLogin->loginReturn->sessionId;
// Set headers-- The remote call "query()" will require a header pointing to our session.
$strHeaderComponent_Session = "<SessionHeader><sessionId>$strSessionID</sessionId></SessionHeader>";
$objVar_Session_Inside = new SoapVar($strHeaderComponent_Session, XSD_ANYXML, null, null, null);
$objHeader_Session_Outside = new SoapHeader('namespace.com', 'SessionHeader', $objVar_Session_Inside);
// More than one header can be provided in this array.
$objClient->__setSoapHeaders(array($objHeader_Session_Outside));
// Set the query parameters.
$strQuery = 'select empID from Time where empID = 92389278';
$arrParameters_Query = array('queryString' => $strQuery);
// Make call.
$objResponse = $objClient->query($arrParameters_Query);
header('Content-Type: text/xml; ');
print($objClient->__getLastRequest());
The request that goes out:
<SOAP-ENV:Envelope>
<SOAP-ENV:Header>
<SessionHeader>
<sessionId>8789364113604871127</sessionId>
</SessionHeader>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<ns1:query>
<ns1:queryString>select empID from Time where empID = 92389278</ns1:queryString>
</ns1:query>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Here is a way to get headers on the server side. It will fill up an assoc with all headers in a namespace. In its current state, it only handles text content; but each header is expanded to a DOMNode, so you can do whatever you wish to parse custom types.
In my case this method is useful because I want to pass PHPSESSID in a SOAP header, and I need to set it before I even call SoapServer::handle().
//
// READ SOAP HEADERS, STOP READING AT SOAPENV:BODY ELEMENT
//
$xml = new XmlReader();
$xml->XML( $HTTP_RAW_POST_DATA );
$shoppingCartHeaders = array();
while( $xml->read() ) {
if( $xml->namespaceURI == "urn:com.plauditdesign.shoppingcart.client.headers#"
&& $xml->nodeType == XMLReader::ELEMENT ) {
$headerNode = $xml->expand();
$shoppingCartHeaders[ $xml->localName ] = $headerNode->textContent;
} elseif( $xml->namespaceURI == "http://schemas.xmlsoap.org/soap/envelope/"
&& $xml->nodeType == XMLReader::ELEMENT
&& $xml->localName == "Body" ) {
$xml->close();
}
}
...
if( isset( $shoppingCartHeaders["sessionId"] ) ) {
session_id( $shoppingCartHeaders["sessionId"] );
}
...
$server->setPersistence( SOAP_PERSISTENCE_SESSION );
$server->handle();
To build the authentication headers like below FOR WSDL:
**NOTE** I cannot find documentation on the __setSoapHeaders() method, though it does work in 5.0.4
<?php
class MySoapClass
{
function __construct(){
// Blah blah blah
$this->soap = new SoapClient($this->foo, $this->bar);
}
// Build that header!
private function build_auth_header(){
// Build an object with parameters
$auth->username = $this->username;
$auth->password = $this->password;
$authvalues = new SoapVar($auth, SOAP_ENC_OBJECT);
$header = new SoapHeader($this->name_space, "Authentication", // Rename this to the tag you need
$authvalues, false);
$this->soap->__setSoapHeaders(array($header));
}
// Wrapper so we can build auth header first
public function MySoapFunction($params){
$this->build_auth_header();
$this->soap->MySoapFunction($params);
}
}
?>
In botoom code is bug.
is:
// create authentication header values
$authvalues=new SoapVar($auth,SOAP_ENC_OBJECT,'authenticate');
should be:
// create authentication header values
$authvalues=new SoapVar($auth,SOAP_ENC_OBJECT);
If you are using WSDL to define your SOAP Headers, note that PHP's SoapServer class will not process incoming headers unless the <message> and <part> names are identical for the header methods.
Define a SOAP header function like this in WSDL:
<!-- replace "tns:" with your own namespace abbreviation -->
<!-- define method arguments using a complexType -->
<xsd:complexType name="HeaderMethodArgs">
<xsd:all>
<xsd:element ... name="arg1"/>
<xsd:element ... name="arg2"/>
</xsd:all>
</xsd:complexType>
<!-- define method message with single part -->
<message name='headerMethodName'>
<part name='headerMethodName' type='tns:HeaderMethodArgs'/>
</message>
<!-- add header tag to operations that use this header -->
<operation name='someBodyMethod'>
...
<input>
<soap:body .../>
<soap:header
...
message='tns:headerMethodName'
part='headerMethodName'
/>
</input>
<output>...</output>
</operation>
If you are trying to create a header like this:
<SOAP-ENV:Header>
<ns2:authenticate SOAP-ENV:actor="http://schemas.xmlsoap.org/soap/actor/next">
<username>myuser</username>
<password>secret</password>
</ns2:authenticate>
</SOAP-ENV:Header>
Try to use a class to create Header-vars:
class authentication_header {
private $username;
private $password;
public function __construct($username,$password) {
$this->username=$username;
$this->password=$password;
}
}
In your soap client program:
// generate new object
$auth=new authentication_header('myuser','secret');
// create authentication header values
$authvalues=new SoapVar($auth,SOAP_ENC_OBJECT,'authenticate');
// generate header
$header=new SoapHeader("myURN",
"authenticate",
$authvalues,
false,
"http://schemas.xmlsoap.org/soap/actor/next");
And do the request like this (non-WSDL version):
$client->__call('function', $params, null, $header);
Have fun,
