HTTP_INVALID_STATE

[Former Member]

Hi, All,

I am using if_http_client to consume an external web service over https,

the following code works fine in a none-unicode system, but got a HTTP_INVALID_STATE exception from if_http_client->receive method call in an unicode activated system.

CALL METHOD cl_http_client=>create_by_destination

EXPORTING

destination = 'dest' "rfc_dest

IMPORTING

client = eo_client

EXCEPTIONS

argument_not_found = 1

plugin_not_active = 2

internal_error = 3

destination_not_found = 4

destination_no_authority = 5.

CASE sy-subrc .

ENDCASE.

CALL METHOD eo_client->request->set_header_field

EXPORTING

name = '~request_method'

value = 'POST'.

CALL METHOD eo_client->request->set_header_field

EXPORTING

name = 'Content-Type'

value = 'text/xml; charset=utf-8'.

rlength = XSTRLEN( out_soap_stream ) .

MOVE: rlength TO txlen .

CALL METHOD eo_client->request->set_header_field

EXPORTING

value = txlen.

CALL METHOD eo_client->request->set_header_field
