You can do that with the class "cl_http_client".

Sample code:



DATA: http_client TYPE REF TO if_http_client .

DATA: w_string TYPE string ,
w_result TYPE string ,
r_str TYPE string .

DATA: result_tab TYPE TABLE OF string.

START-OF-SELECTION .
CLEAR w_string .
w_string = 'http://urlhost/Logs/main.asmx/SetLog'.

CALL METHOD cl_http_client=>create_by_url
EXPORTING
url                = w_string
IMPORTING
client = http_client
EXCEPTIONS
argument_not_found = 1
plugin_not_active  = 2
internal_error     = 3
OTHERS = 4.

CALL METHOD HTTP_CLIENT->REQUEST->SET_HEADER_FIELD
EXPORTING
NAME = '~request_method'
VALUE = 'POST'.

CALL METHOD http_client->REQUEST->SET_FORM_FIELD
EXPORTING
NAME = 'title'
VALUE = 'Mail sistema'.

CALL METHOD http_client->REQUEST->SET_FORM_FIELD
EXPORTING
NAME = 'details'
VALUE = 'Funcion 1234'.

CALL METHOD http_client->send
EXCEPTIONS
http_communication_failure = 1
http_invalid_state         = 2.

CALL METHOD http_client->receive
EXCEPTIONS
http_communication_failure = 1
http_invalid_state         = 2
http_processing_failed     = 3.
CLEAR w_result .
w_result = http_client->response->get_cdata( ).

REFRESH result_tab .
SPLIT w_result AT cl_abap_char_utilities=>cr_lf INTO TABLE
result_tab .

READ TABLE result_tab INTO r_str INDEX 2.
