soap_server::parseRequest() have two param :$header & $data,
question:How Can I get the $data,thank u!

In most cases you'd not call this method directly. It receives http headers and post payload as data from the client. Why would you need to call them directly?

The client send a httpquest contains xml and Attachments;
en,I wanna receive the soap object with xml and Attachments from client.
thank U

All things sent by client are in $_POST (parsed values) or in $HTTP_RAW_POST_DATA (not parsed)
