∟RPC Style Example - Get Stock Price

This section provides a tutorial example on writing a WSDL 2.0 example that uses SOAP 1.2 over HTTP with RPC as the message style.

My next WSDL 20 example was converted from the WSDL 1.1 version:

Location: https://www.herongyang.com/service/ GetStockPrice_WSDL_20_SOAP_12_RPC.wsdl.
WSDL Version: 2.0
WSDL Message Exchange Pattern: In-Out
WSDL Message Style: RPC
Binding Extension: SOAP
SOAP Version: 1.2
SOAP MEP: request-response
SOAP Transportation Protocol: HTTP

In this WSDL example, I want to send a SOAP request to call a RPC function to get a stock price. The function expects 3 input positional parameters and returns 1 value.
