How to call WebService in delphi

First, the server should have an interface document address, such as http://ip:port/interfacename? Wsdl. Import the interface document with import wsdl in delphi, and there will be a global method of GetqqXXXWebServiceSoap in the interface document. You need to pass in an httprio object, and calling this method will return an interface object, through which you can call the method of webservice.
