BSP Navigation Check

Former Member — Wed, 26 Sep 2012 15:57:00 GMT

Hi All,

I have a scenario where in we have a enhancement to open a PDF file in portal with standard SAP HCM_LEARNING application. If file does not exist then I need to give the custom messages.To give the custom message we need to check that whether the URL of PDF file is valid or not. Currently I am using HTTP2_GET function module to validate the same.This FM returns the status code by which we can know whether this URL is accessible or not. This function module requires a RFC destination as a input parameter . I am using SAPHTTPA for the same. This RFC Destination (TCP/IP) does not have credentials with it , so the return status code is always 401 (unauthorised ). I also tried to use other RFC destinations(of type G) that have credentials with it but this is not compatible with this FM.

Can you help me in regard to below queries:

Is there any other method that we can use to validate the URL ?

How we can use the session variables (as the user has already logged in so that it should not ask for credentials.)

Is there any way to specify the Credentials in the RFC destination of type T?

I want to know how to validate the URL without logging to portal or how to bypass the authentication popup.

Kindly share your inputs with me to fix the same.

Thanks.

Thanks for the reply,

I have used the CL_HTTP_CLIENT class with CREATE_BY_URL method but everytime It is giving me sy-subrc eq 0.It is not throwing any Exception ,HTTP_COMMUNICATION_FAILURE .

It is working in same way whether the URl is correct or not.

Thanks.

Did you call the send method after calling create_by_url? You should get the exception there.

OTHERS = 999 ).

IF lr_client IS NOT BOUND OR sy-subrc NE 0.

gv_msg = 'Problem occured while removing the document'(005).

RETURN.

Its not validation the URL. In the method HTTP2_GET it is asking for authorization and I have no clue how to get the Authorization data to it.Since the User has logegd in to Portal Is there any way so that I can pass the username and password to it.

It also has input parameter for Proxy user and password. Don't know what is this.

I am using This FM:

call function 'HTTP2_GET'

exporting

absolute_uri = URL

rfc_destination = RFCDESTINATION

PROXY = ??

PROXY_USER = ??

PROXY_PASSWORD = ??

USER = ??

PASSWORD = ??

USER = ??

PASSWORD = ??

importing

STATUS_CODE = status

response_entity_body_length = length

tables

response_entity_body = body

response_headers = header

exceptions

connect_failed = 1

timeout = 2

internal_error = 3

tcpip_error = 4

others = 5.

if status eq '200'.

navigation->goto_page( URL ).

elseif status eq '404'.

Show the message URL not accessible

endif.

Any Suggestions please Reply.
