Library: omhttp - HTTP support Include: omhttp.xin

Declaration

  define function HttpObjectGetHeaders
              read-only   stream   HttpObject
     into     modifiable  stream   Headers

  where

HttpObject

is an HTTP request or HTTP response object (input argument).

Headers

is a returned shelf containing the headers as keyed items. The contents of the shelf are cleared before the headers are copied to it. The item key is the header name (output argument)

Use HttpObjectGetHeaders to get the names and values of all headers defined for the HTTP request or response object. The values are returned as keyed items in a stream shelf.

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omhttp.xin"

Usage Notes

HttpObjectGetHeaders is usually called in a server program.

Example

This code outputs all headers and their corresponding keys.

  ; HttpObjectGetHeaders
  include "omhttp.xin"

  process
     local HttpRequest my-Request
     local HttpResponse my-Response
     local stream request-Headers variable
     local stream response-Headers variable

     HttpObjectGetHeaders my-Request into request-Headers
     HttpObjectGetHeaders my-Response into response-Headers

     output "Request headers:%n"
     repeat over request-Headers
        output key of request-Headers || "=%g(request-Headers)%n"
     again
     output "Response headers:%n"
     repeat over response-Headers
        output key of response-Headers || "=%g(response-Headers)%n"
     again
