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.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set rest = CreateObject("Chilkat.Rest")
bTls = 1
bAutoReconnect = 1
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = 0) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

'  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 = CreateObject("Chilkat.Stream")
bodyStream.SourceFile = "qa_data/upload.json"

success = rest.AddHeader("Content-Type","application/json")

'  The 3rd argument is the Stream that supplies the request body.
responseText = rest.FullRequestStream("POST","/api/upload",bodyStream)
If (rest.LastMethodSuccess = 0) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine(responseText)

outFile.Close
