Consuming Rest based Https service in abap.

Former Member — Fri, 20 Nov 2015 11:17:53 GMT

Hi ,

I am trying to consume an external rest service in ABAP.

I am having an issue with the IF_HTTP_CLIENT~RECEIVE method.

It hangs indefinitely. If you have encountered same issue please help.

CLEAR w_string .
w_string = "https//:XXXx.com"

  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->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.

So you have create all the necessary data : SOAMANGER / LPCONFIG / ....

*---------------------------------------------------------------------*

* Form P_SEND_FILE. *

*---------------------------------------------------------------------*

form p_send_file.

data : ls_result type zaipwsimport_fichier_soap_out ,

ls_send type zaipwsimport_fichier_soap_in ,

ls_sys_exception type ref to cx_ai_system_fault ,

lv_string type string ,

lv_xstring type xstring .

* Créé le string.

concatenate lines of gt_tab into lv_string separated by space.

* Créé le XString

call function 'SCMS_STRING_TO_XSTRING'

exporting

text = lv_string

importing

buffer = lv_xstring

exceptions

failed = 1

others = 2.

ls_send-content = lv_xstring.

ls_send-str_directory = 'The directory'.

ls_send-str_file_name = 'The file name'.

try.

create object oo_proxy

exporting

logical_port_name = 'Fxxxxx_HTTPS_002'. " 'TxxxxxxIQ'.

catch cx_ai_system_fault into ls_sys_exception.

if ls_sys_exception is not initial.

write : /1 'System fault occured' ,

ls_sys_exception->code ,

ls_sys_exception->errortext .

endif.

endtry.

check oo_proxy is not initial.

try.

call method oo_proxy->import_document

exporting

import_fichier1 = ls_send

importing

import_fichier = ls_result.

catch cx_ai_system_fault into ls_sys_exception.

if ls_sys_exception is not initial.

write : /1 'System fault occured' ,

ls_sys_exception->code ,

ls_sys_exception->errortext .

endif.

catch cx_ai_application_fault .

Hi Frederic,

It is not a soap service. It is a rest service.
