CL_HTTP_CLIENT 400 Bad HTTP Request - Parameter with Space ' ' in name

Pyc — Mon, 14 May 2012 03:57:32 GMT

G'day all,

I'm using CL_HTTP_CLIENT to interact with an external system which offers a URL based interface. This works fine until I have a parameter name with a space in it, at which point I get a "400 Bad HTTP request" response with the following detail:

Error: -21

Version: 7200

Component: HTTP_PLG

Date/Time: Mon May 14 13:40:28 2012

Module: http_plg.c Line: 5613

Server: SYDSVECCDEV_AED_00

Error Tag: {0003b201}

Detail: illegal request version

I'm creating the instance of CL_HTTP_CLIENT via method CREATE_BY_DESTINATION and then passing the rest of the URL by calling method REQUEST->SET_HEADER_FIELD passing name '~request_uri'.

When I pass something like the following it works fine:

?&action="create"&type="account - customer"&id="ACCOUNT926"&priority="12"

But when the parameter has a space such as 'accession number' below, it results in the 400 response.

?&action="create"&type="account - customer"&id="ACCOUNT926"&accession number="12"

I've tried manually replacing the space with %20.

I've tried using the 'IF_HTTP_CLIENT~ESCAPE_URL' method on the string.

I've tried to build the URL extension using method APPEND_FIELD_URL

In each case I get the 400 response.

Can anyone advise how I can successfully call such a URL or if there is just some limitation that means I can't use CL_HTTP_CLIENT in such a scenario??

I should also say that the URL with 'accession number' works fine when run directly in Internet Explorer.

Many thanks,

Mark

Hi Mark,

Can you try replacing the space with a '+' sign?

Or you can do the easy thing, by removing the space
