How to use initial HTTP request (not from HTTP client)

[dschiener]

Hi there,

I want to send a newly created HTTP request based on if_http_request or cl_http_request without using the request which is stored in the HTTP client.

I guess the default way to send a HTTP request looks kind of like this:

DATA(client) = cl_http_client=>create( ).
" Prepare request
client->request->set_method( ... ).
client->request->set_header_field( ... ).
...

client->send( ... ).

By debugging, this way is working, not least because the request object stored in the client contains a member attribute named m_c_msg that is initialized.

I would like to decouple the creation and initialization of the HTTP request by underlying the HTTP client:

DATA(client) = cl_http_client=>create( ).

" Prepare request
DATA(request) = NEW cl_http_request( ).
request->set_method( ... ).
request->set_header_field( ... ).
...

client->request = request.
client->send( ... ).

In my way the request seems not to be initialized correctly and therefore the sending fails.

Can anyone tell me if it is possible to implement my prefered solution and give me some hints?

When creating the new request by using a system call like in the original SAP code I receive a 401 response.

SYSTEM-CALL ict "#EC CI_SYSTEMCALL
  DID
    ihttp_scid_create_message
  PARAMETERS
    1
    message_pointer
    error.

DATA(request) = NEW cl_http_request( c_msg = message_pointer ).

EDIT: Solved. Added the authentication credentials to the request by calling

request->set_authorization( .. )

Now it works. But I'm still not sure if this is a recommended solution to solve this.
Not sure about the side effects and functionality of the system call. Guess that it simply creates a new memory buffer to store the request...
