I sent this message to the php.soap newsgroup, but noone answered me.
Today I found a nasty problem with a simple php SOAP client. Never had
problems before, but today I have the following error at SOAPClient
constructor line:
SoapClient::SoapClient(http://www.w3.org/2001/xml.xsd): failed to open
stream: HTTP request failed! HTTP/1.1 401 Authorization Required
The source is as simple as:
$client = new SoapClient("http://my.host.com/my_web_service?wsdl";,
array( 'trace' => TRUE,
'login'=>'mylogin',
'password'=>'secret'
)
);
It seems that the php xml parser tries to fetch the url
http://www.w3.org/2001/xml.xsd at wsdl parsing time. Sniffing the
network operations I found that php uses my login and password (for the
web service) also to access external references! :-O
GET /2001/xml.xsd HTTP/1.0
Authorization: Basic bXlsb2dpbjpzZWNyZXQ=
Host: www.w3.org
In the past probably w3.org just ignored the issue, but now I receive an
HTTP 401 Unauthorized error in response...
In any case it is a serious security issue if SOAPClient sends password
around the web, when the intent is that they are used only for the web
service host!
I tried the following PHP versions:
