HTTP Adapter Reference Guide

Example Files

To access an example for this adapter, click Start > Programs > Mercator

version number > Design Studio > Examples and navigate to Resource

Adapters.

The following examples can be found in this directory.

♦ Using the Map Designer, select HTTP from the Source setting in an Input

Card dialog box. In the GET > Source > Command field, type the -URL

command to specify the uniform resource locator (URL) specifying the HTTP

server, the file to transfer, and other required adapter commands. In this input

card example, the HTTP adapter retrieves the test.htm file from host server

puff:

-URL HTTP//user1:test@puff:8080/c:/test/tst.htm

♦ Using the Integration Flow Designer to override the HTTP adapter settings for

an input card, enter the following for the Source > GET > Source >

Command setting in the Event Server settings:

-TV –REDIR 3 –URL HTTP://user1:pass@puff:8080/c:/orb/original.htm

The adapter specifies the original.htm file to be used as the data source. The

-TV adapter command specifies that the adapter generate a verbose trace file

containing a log of all activity and events occurring while the adapter is

retrieving data. The -REDIR 3 adapter command specifies that the HTTP

adapter will follow three file redirections (or "document moved" messages)

before the file transfer request fails.

♦ Using the Input Source Override – Application Execution Command (

-IA), this

command string example can be used to override the adapter commands

defined in output card 1:

-IAHTTP1 '-URL HTTP://user1:test@puff:8080/c:/test/test.htm'

This example command string causes the file test.htm to be retrieved from

host server puff.

♦ Use the

M4HHTP_OPT environment variable to specify commands to the HTTP

adapter or a command file containing adapter commands.

Note Commands specified in the input or output card settings override commands

specified in the environment variable.

The format for specifying commands is:

M4HHTP_OPT=adaptercommands
