Hi @Vikas : Did you use oauth profile to get oauth Token?

[sergei-u-niq]

just add Header

Authorization: Bearer xxxxxxxTOKENxxxx

[vikash_pathak]

Where do i need to add this authorization?

i have written this code

data: lo_request1 type ref to if_rest_entity.
*      lo_rest_client type ref to cl_rest_http_client.
CLEAR:LV_GITHIB_url .




LV_GITHIB_url = 'https://xxxxxxxxxxxxxxxxx'.
cl_http_client=>create_by_url(
      EXPORTING
        url                = LV_GITHIB_url
        ssl_id             = 'ANONYM'
      IMPORTING
        client             = http_client
      EXCEPTIONS
        argument_not_found = 1
        plugin_not_active  = 2
        internal_error     = 3
        OTHERS             = 4 ).
    IF sy-subrc <> 0.
      CLEAR ev_response.
      RETURN.
    ENDIF.
DATA(lo_rest_client) = new cl_rest_http_client( IO_HTTP_CLIENT = http_client ).
http_client->propertytype_logon_popup = http_client->co_disabled.
lo_request1 = lo_rest_client->if_rest_client~create_request_entity( ).
lo_request1->set_content_type( iv_media_type = if_rest_media_type=>gc_appl_json ).
lo_request1->set_header_field( iv_name  = 'X-CSRF-Token' iv_value = ev_reason1 ).
lo_request1->set_header_field( iv_name = 'X-Requested-With' iv_value = 'X' ).
cl_http_utility=>set_request_uri( request = http_client->request
                                uri    = LV_GITHIB_url ).


  lo_request1->set_string_data( wf_string1 ).


  lo_rest_client->if_rest_resource~post( lo_request1 ).


  lo_response = lo_rest_client->if_rest_client~get_response_entity( ).


  lv_http_status = lo_response->get_header_field( '~status_code' ).


  lv_response = lo_response->get_string_data( ).


  write:/ lv_http_status.
  write:/ lv_response.

use

lo_request->set_header_field( iv_name='Authorization' iv_value = |Bearer { lv_token }| )

on your second call

Hi Sergei Haller,

i tried with it , but getting 401 unauthorized error .

Thanks

[sergei-u-niq]

Well, thats how a bearer token is transported. Does it work in Postman or other tools? is your token correct?

[vikash_pathak]

Hello sergei.haller.u-niq,

yes i am using the correct Token and i tested it on postman and its working there,

if i donot use http_client->propertytype_logon_popup = http_client->co_disabled. this code login screen popup for user id nd password even after using below code.

LV_GITHIB_url = 'https://xxxxxxxxxxxxxxxxxxxxxxxx'.
cl_http_client=>create_by_url(
      EXPORTING
        url                = LV_GITHIB_url
        ssl_id             = 'ANONYM'
      IMPORTING
        client             = http_client
      EXCEPTIONS
        argument_not_found = 1
        plugin_not_active  = 2
        internal_error     = 3
        OTHERS             = 4 ).
    IF sy-subrc <> 0.
      CLEAR ev_response.
      RETURN.
    ENDIF.
DATA(lo_rest_client) = new cl_rest_http_client( IO_HTTP_CLIENT = http_client ).
lo_request1 = lo_rest_client->if_rest_client~create_request_entity( ).
*http_client->propertytype_logon_popup = http_client->co_disabled.
lo_request1->set_content_type( iv_media_type = if_rest_media_type=>gc_appl_json ).
lo_request1->set_header_field( iv_name = 'Authorization' iv_value = |Bearer { ev_reason1 }| ).

                                uri    = LV_GITHIB_url ).




  lo_request1->set_string_data( wf_string1 ).

[sergei-u-niq]

you are passing ev_reason1 as CSRF token and as Bearer Token. It cant be both. Which one is it?

[vikash_pathak]

Hello Sergei Haller,

its X-CSRF-Token

[sergei-u-niq]

your initial question was "how to use Bearer Token for authentication" => use "Authorization: Bearer xxxTokenxxx" for that.

[raya_hemanth]

Hi ,

When requesting for token how to set header content length. I am getting error message "HTTP Error 411. The request must be chunked or have a content length." while requesting for token. Appreciate your help.

Thanks and regards,

~Hemanth
