Http Client

[Former Member]

hello i have created httpclient object in my prgram.

i sent request using httpclient, and source had life time set to session, and in my first request i set some page attributes.

now i am trying to use the same httpclient object in same program after first call to send request to same resource again assuming that httpclient now has all sesssion information that is required for web server to recognize a request for already created session but i cant get page attributes value that i expect because they are initial in second time,,so what should i do?

here is the code that might be helpful,,,,,

call method cl_http_client=>CREATE_BY_URL

EXPORTING

url = url

IMPORTING

client = httpClient.

httpClient->request->SET_HEADER_FIELD( name = '~request_uri'

value = uri ).

httpClient->request->SET_HEADER_FIELD( name = '~request_method'

value = 'POST' ).

httpClient->request->set_form_field( name = 'hello' value =

'World' ).

httpClient->request->set_form_field( name = 'mentor' value = 'daniel'

).

httpClient->send( httpClient->CO_TIMEOUT_INFINITE ).

call method httpClient->RECEIVE

EXCEPTIONS

HTTP_COMMUNICATION_FAILURE = 1

HTTP_INVALID_STATE = 2

HTTP_PROCESSING_FAILED = 3.

if sy-subrc = 0.

• lastErrorMessage = 'Okay'.

• lastErrorCode = 0.

• errorCode = '-'.

data sTemp type string.

sTemp = httpClient->response->GET_CDATA( ).

create object printXMLDoc.

rc = printXMLDoc->parse_string( sTemp ).

call method printxmlDoc->display( ).

else.

call method httpClient->GET_LAST_ERROR

IMPORTING

code = lastErrorCode

message = lastErrorMessage.

write 😕 lastErrorMessage.

endif.

• now here is another request using same object,,nd ******server resource is valid or active for session.

httpClient->request->SET_HEADER_FIELD( name = '~request_uri'

value = uri ).

httpClient->request->SET_HEADER_FIELD( name = '~request_method'

value = 'POST' ).

httpClient->request->set_form_field( name = 'hello' value =

'World' ).

httpClient->request->set_form_field( name = 'mentor' value = 'daniel Mcweeney'

).
