Is it possible to call an URL with automatic login?

[Former Member]

Hello,

how can I call an URL from SAP (with report or fuba) with automatic login?

Example: I call the URL https://appdemo.docusign.com/home

then I have login in Internet Explorer.

Via http_client I can set the Login E-Mail and Password.

I get the response everything is ok. But how can I call the url now.

Hi

Just set the API Url and send the request - the authentication info is either stored in a cookie (will be sent automatically) or you need to set some header field or GET/POST parameter

lo_http_client->refresh_request( EXCEPTIONS http_action_failed = 1
                                            OTHERS             = 2 ).
IF sy-subrc <> 0.
  "Error Handling
ENDIF.

cl_http_utility=>set_request_uri( request = lo_http_client->request uri = 'API URL' ).

lo_http_client->send( EXCEPTIONS http_communication_failure = 1
                                 http_invalid_state         = 2
                                 OTHERS                     = 3 ).
IF sy-subrc <> 0.
  "Error Handling
ENDIF.

How can I get here the url from response and call it with CALL_BROWSER?

[Domi]

Hi

This is part of the API - I know some of them, but definitely not all!

Just get the AUTH token and provide it with the next call (e.g. with method CL_GUI_HTML_VIEWER->SHOW_URL_IN_BROWSER)

And please: RTFM

regards

Create a destination in SM59, with the credentials for login. Then use cl_http_client=>create_by_destination to get your client.

See here for details https://blogs.sap.com/2014/11/09/calling-an-external-restful-service-from-abap-http-method-get/

I tried and can not call the url on ie.

Sorry. Thought you were consuming a webservice. Didn't realise you actually want a browser session.

Please post a new question (CALL_BROWSER automatic login via HTTPS), as it's different from your original question (automatic login via CL_HTTP_CLIENT)
