Get raw HTTP response data (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.
%string = httpResponse:Content[( [number])]
|%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.|
- 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.
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) ...
- For information about returning response contents into a Stringlist, see the ContentToStringlist method.
