Send a REST Request with a Streamed Body

See more REST Examples

Demonstrates Rest.FullRequestStream, which sends a complete request whose body is read from a Stream, then returns the response body as text.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

load ./chilkat.dll

set success 0

set rest [new_CkRest]

set bTls 1
set bAutoReconnect 1
set success [CkRest_Connect $rest "example.com" 443 $bTls $bAutoReconnect]
if {$success == 0} then {
    puts [CkRest_lastErrorText $rest]
    delete_CkRest $rest
    exit
}

#  The file paths are relative to the application's current working directory.  Absolute paths
#  may also be used.  Supply the paths appropriate to your own environment.

#  The request body is read from a Stream.  Here the stream's source is a local file, which is
#  appropriate for large uploads because the data need not be held entirely in memory.
set bodyStream [new_CkStream]

CkStream_put_SourceFile $bodyStream "qa_data/upload.json"

CkRest_AddHeader $rest "Content-Type" "application/json"

#  The 3rd argument is the Stream that supplies the request body.
set responseText [CkRest_fullRequestStream $rest "POST" "/api/upload" $bodyStream]
if {[CkRest_get_LastMethodSuccess $rest] == 0} then {
    puts [CkRest_lastErrorText $rest]
    delete_CkRest $rest
    delete_CkStream $bodyStream
    exit
}

puts "$responseText"

delete_CkRest $rest
