Dynamic WebService calls the interface and reads the parse return result

WebService releases are typically published using the style of the WSDL (Web Service descriptive language) file, which contains the interface that the webservice exposes to use in the WSDL file. Today we'll talk about how to dynamically invoke and read the parse return result

Here is a dynamic WebService call interface and read the resolution return results of a specific example, very simple, comments are very detailed, small partners can refer to.
