I haven't used the following on PWS, but I recommend Andreas'
approach because of potential buffering of stdin with large amounts
of data:
;;======================================================================================================
;; Courtesy of Andreas Bolka <[andreas--bolka--gmx--net]>
;;======================================================================================================
read-post-data: func [
{Reads the HTTP entity body}
/safe "Disables evaluation of content-length header."
/local len data tmp
] [
len: load any [ all [ safe "65536" ] system/options/cgi/content-length "0" ]
data: make string! len
tmp: make string! len
while [ 0 < read-io system/ports/input tmp len ] [
insert tail data tmp
clear tmp
]
data
] ; end: sub
;; The 'while loop checks the return value from read-io to ensure
;; that all data is read.
;; Good work Andreas!
