Not sure whether the HTML code of a webpage can be read in ABAP. But webservices can be invoked through it.

Check this link.....

Hi RagnaRock,

You can use the following form, hope it helps you.

Regards,

Ozcan.

form get_data_from_url using iv_url type clike changing iv_data type string.

DATA: HTTP_CLIENT TYPE REF TO IF_HTTP_CLIENT .
  clear  iv_data.

  CALL METHOD CL_HTTP_CLIENT=>CREATE_BY_URL
       EXPORTING
        URL                = IV_URL
*          PROXY_HOST         = '10.1.1.1'
*          PROXY_SERVICE      = '1234'
*       SSL_ID             =
       IMPORTING
         CLIENT             = HTTP_CLIENT
       EXCEPTIONS
         ARGUMENT_NOT_FOUND = 1
         PLUGIN_NOT_ACTIVE  = 2
         INTERNAL_ERROR     = 3
         OTHERS             = 4.

  CHECK SY-SUBRC = 0.

  CALL METHOD HTTP_CLIENT->SEND
    EXCEPTIONS
      HTTP_COMMUNICATION_FAILURE = 1
      HTTP_INVALID_STATE         = 2.

  CHECK SY-SUBRC = 0.

  CALL METHOD HTTP_CLIENT->RECEIVE
    EXCEPTIONS
      HTTP_COMMUNICATION_FAILURE = 1
      HTTP_INVALID_STATE         = 2
      HTTP_PROCESSING_FAILED     = 3.
  CHECK SY-SUBRC = 0.

  iv_data = HTTP_CLIENT->RESPONSE->GET_CDATA( ).

endform.                    "get_data_from_url

I've tried this, but I'm getting sy-subrc = 1 when I do the receive part.

I'm sure the site exists and is online, what could be the problem?

edit

actually I only get subrc = 1 if I execute this code outside the form, If I do it just like you did, using:

PERFORM get_data_from_url USING 'http://www.jogosbaratos.net' CHANGING html_code.

I always get subrc = 0 but html_code comes empty

any idea?

the http_get did work

I solved this using the FM http_get, but I'm having some problems with the encoding.

for example if the webpage apears 'é' in my table apears 'é'

is there any way to change the text enconding?

thanks

Hello friend,

you can also try with function module HTTP_GET.

Best Regards,
