HTTP AND PDF file download

Posted on Dec 28, 2005 at 01:09 AM 386 Views

I have some problems to send a PDF FILE to a http server using if_http_client class with for example methods :

CALL METHOD client->request->set_header_field

CALL METHOD client->send

CALL METHOD client->receive

I don’t want to use FM SO_NEW_DOCUMENT_ATT_SEND_API1, SO_NEW_DOCUMENT_ATT_SEND_MAPI , SO_NEW_DOCUMENT_SEND_API1

Could someone please give me a sample abap program doing this ?

It could be great.

Thanks

    Welcome to SDN.

    1. upload the pdf file to a itab using GUI_UPLOAD (file type 'BIN') ( i assume that you are doing this abap program and not in BSP page)

    2. create a instance of cl_http_client

    call method cl_http_client=>create

    exporting

    host = 'www.server.com'

    service = '80'

    scheme = '1'

    importing

    client = http_client.

    3. set header fields.

    call method http_client->request->set_header_field

    exporting

    name = '~request_method'

    value = 'POST'.

    call method http_client->request->set_header_field

    exporting

    name = '~server_protocol'

    value = 'HTTP/1.1'.

    call method http_client->request->set_header_field

    exporting

    name = 'Content-Type'

    value = 'application/pdf' .

    call method http_client->request->set_data

    exporting

    data = <xstring holding the uploaded content>

    offset = 0

    length = rlength.

    call method http_client->request->set_header_field

    exporting

    name = 'Content-Length'

    value = txlen.

    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 wf_string1 .

    wf_string1 = http_client->response->get_cdata( ).

    Hope this is clear.

    Regards

    Raja

    A snippet of code that works for me.

    response->set_header_field( name = 'content-type'

    value = 'application/pdf' ).

    • some Browsers have caching probs when loading PDF

    response->set_header_field(

    name = 'cache-control'

    value = 'max-age=0' ).

    • l_pdf_xstring contains PDF data

    l_pdf_len = XSTRLEN( l_pdf_xstring ).

    response->set_data( data = l_pdf_xstring

    length = l_pdf_len ).

    navigation->response_complete( ).

    • End of code

    I am pretty sure SAP delivers an example that runs a smartform via a BSP and reders it as a PDF. Can't seem to find it though.

    Cheers
