Content is a member of the HttpResponse class.

This method lets you access the document/content from Get, Post, and Send operations. Content returns the entire document into a longstring with no parsing: you get the raw bytes as they were returned from the HTTP request, with the option of ASCII-to-EBCDIC translation.

Syntax

%longstring = %httpsresp:Content[(binflag)]

Syntax terms

%longstring A longstring variable.
%httpresp A reference to an HTTPResponse object that was returned by a Get, Post, or Send method of an HTTPRequest object.
binflag A numeric expression that, if nonzero, indicates binary data. Setting this option overrides the default behaviour, which is to translate ASCII data to EBCDIC.

Usage Notes

  • Invoke Content only if a successful HTTP transaction has occurred, that is, if the Success property value is True. If Content is called after an unsuccessful operation, the request is cancelled.
  • If the content type header indicates HTML, XML, or plain text, ASCII-to-EBCDIC translation is performed. If the Clsock port definition specifies a translation table for ASCII-to-EBCDIC, that table is used instead of the default.

Example

In the following fragment, an HTTPResponse object receives a .PDF file from a remote URL into a Longstring, leaving the data in binary format:

%httpreq is object httpRequest %httpresp is object httpResponse %pdf is longstring %url is longstring ... %httpreq = new %httpreq:url = %url %httpresp = %httpreq:get If (%httpresp:Success) then %pdf = %httpresp:content(1) ...
