Differences between HTTP_POST and CL_HTTP_CLIENT

[Former Member]

I use function module HTTP_POST from ABAP to send a request to an external server via HTTPS URL. This works fine I get a response status back of 200 and the external server processed the request and I get a correct response in the body of the response.

When I try and replicate this using the newer method cl_http_client . I get a response status back of 200 but the external server can't process the request and doesn't return the expected body response.

The call to HTTP_POST which works is as below:

The only header request I have to create is Content-type:

All the others are created automatically by the function module

CALL FUNCTION 'HTTP_POST'

ABSOLUTE_URI = url

REQUEST_ENTITY_BODY_LENGTH = l_length

BLANKSTOCRLF = 'X'

IMPORTING

STATUS_CODE = l_status_code

STATUS_TEXT = l_status_text

RESPONSE_ENTITY_BODY_LENGTH = l_length_response

TABLES

REQUEST_ENTITY_BODY = GT_REQUEST_ENTITY_BODY

RESPONSE_ENTITY_BODY = GT_RESPONSE_ENTITY_BODY

RESPONSE_HEADERS = GT_RESPONSE_HEADERS

REQUEST_HEADERS = GT_REQUEST_HEADERS

When I try and replicate this call using cl_http_client

I disable the compress.

l_http_client->propertytype_accept_compress = l_http_client->co_disabled.

<b>How do I replicate the BLANKSTOCRLF = 'X' in the HTTP_POST function module?</b>

The headers that I have to create are now Content-type and Content-length.

when SAP creates the HTTP request it converts these to all lower case e.g. content-type and content-length. Is there anyway I can stop this from happening.

Thanks,

when using cl_http_client

call method cl_http_client=>create

exporting

host = 'www.webservicex.net'

service = '80'

scheme = '1'

proxy_host = wf_proxy

proxy_service = wf_port

importing

client = http_client.

the scheme has to be 2 to tell it that is https

and for setting content type and length the code would be something like below.

call method http_client->request->set_header_field

exporting

name = 'Content-Type'

value = 'text/xml; charset=utf-8'.

call method http_client->request->set_header_field

exporting

name = 'Content-Length'

value = txlen.
