Class httpHelper

java.lang.Object

bradleyross.common.httpHelper

public class httpHelper
extends Object

Provide a set of methods that will help in processing the contents of web pages.

Some methods need to be added for escaping and unescaping character strings. For text that appears in web pages, this would include the handling of ampersands, less than, and greater than symbols

It may also be necessary to include something for the handling of material inside quoted strings. (both single and double quotes)

readHttpPage

public String readHttpPage(String host,
                           int port,

                    throws IOException

Copy the contents of a web page into a String object

It may be advantageous to have these routines able to time out in the same way as the methods in FileHelpers. The first thing to do would be to use the set timeout methods for Socket.

Parameters:

host - Domain name or IP address of web server (Domain name only. e.g. www.cnn.com)

port - Port number for web server

fileName - Directory and name for web page (No leading slash. e.g. index.html)

Returns:

string containing contents of web page

Throws:

IOException - if IO error occurs
