Facebook Image Post Request

[Former Member]

Hi guys, i´m implementing a Facebook Photo Request from ABAP, using fiddler I create this message that was succesfully posted in facebook page, now I´m trying to copy this post using if_http_client and if_http_entity multipart methods.

POST https://graph.facebook.com/xxxxxxxx/photos?access_token=CAAUnJCRRhVUBAPFMl8p53wH8qfSuZAUZBo1IZCWJIo4... HTTP/1.1
Content-Type: multipart/form-data; boundary=-------------------------acebdf13572468
User-Agent: Fiddler
Host: graph.facebook.com
Content-Length: 758192


---------------------------acebdf13572468
Content-Disposition: form-data; name="fieldNameHere"; filename="2012-Fiat-500-Abarth-Rear-Angle-Speed-Tilt-1920x1440.jpg"
Content-Type: image/jpeg

I already set the header fields Content-Type / Content-length but I´m having some issues trying to replicate the boundary in the body in line 08. Here is my code in ABAP that represents the line 08 to 10 + the content of the photo to upload.

lr_part = lr_client->request->if_http_entity~add_multipart( ).

     CONCATENATE 'form-data; name="fieldNameHere"; filename="' iv_file_name '";' INTO lv_file_header.

     CALL METHOD lr_part->set_header_field
       EXPORTING
         name  = 'content-disposition'
         value = lv_file_header.

     CALL METHOD lr_part->set_content_type
       EXPORTING
         content_type = 'image/jpeg'.

     lv_len = XSTRLEN( iv_file_xstring ).

     CALL METHOD lr_part->append_data
       EXPORTING
         data   = iv_file_xstring
         length = lv_len.

The facebook response is : "(#324) Requires upload file"

Any help will be appreciated

I resolve by myself, the boundary is set by standard I didn´t have to set in the header values, the other thing is that the content-length at header level is set by SAP, i delete that header field in my code.
