The E3ApplicationRequest Class
This class defines an object that conveys information about an HTTP request to an Arbortext PE 应用程序. The Arbortext PE 子进程 creates an E3ApplicationRequest object and passes it as a parameter to the doGet and doPost methods.
An E3ApplicationRequest object provides parameter names and values, HTTP headers, and in HTTP POST requests, a File object representing the posted file to the Arbortext PE 应用程序.
The E3ApplicationRequest class has a set of methods for accessing the parameters in the request object.
