How to Easy… Load an HTML Page into Internal Table
here is a simple code to load an HTML page into a internal table:
” Local Vars
DATA: lo_client TYPE REF TO if_http_client,
lc_url TYPE string,
lc_content TYPE string,
lt_html TYPE TABLE OF string.
” Set html page to load
lc_url = ‘http://www.sap.com‘.
” Create the HTTP client
CALL METHOD cl_http_client=>create_by_url
EXPORTING
url = lc_url
IMPORTING
client = lo_client
EXCEPTIONS
OTHERS = 1.
IF sy–subrc IS NOT INITIAL.
” Error
EXIT.
ENDIF.
” Set the Request type to GET
lo_client->request->set_header_field( name = ‘~request_method’
value = ‘GET’ ).
” Make the call
lo_client->send( ).
” Receive the Response Object
CALL METHOD lo_client->receive
EXCEPTIONS
http_communication_failure = 1
http_invalid_state = 2
http_processing_failed = 3
OTHERS = 4.
IF sy–subrc IS NOT INITIAL.
” Error
EXIT.
ENDIF.
” Get the response content in Character format
lc_content = lo_client->response->get_cdata( ).
” Split content by lines in an internal table
SPLIT lc_content AT cl_abap_char_utilities=>cr_lf INTO TABLE lt_html.
” From here you can parse you html code from table lt_html
It´s done.
This was a great help, but I did find that the webpage I was trying to download required one small change. I had to replace 'cr_lf' with 'newline'.
"Split content by lines in an internal table
SPLIT lc_content AT cl_abap_char_utilities=>newline INTO TABLE lt_html.
This is great help, but I am getting error at 'CALL METHOD lo_client->receive' as HTTP_Communication_failure.
Can you please help me out to fix this error.
I am also facing the exception HTTP_COMMUNICATION_FAILURE
Could you please guide how to proceed.
