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 success As Boolean = False

Dim rest As ChilkatRest
rest.Initialize("rest")
Dim bTls As Boolean = True
Dim bAutoReconnect As Boolean = True
success = rest.Connect("example.com", 443, bTls, bAutoReconnect)
If success = False Then
    Log(rest.LastErrorText)
    Return
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.
Dim bodyStream As ChilkatStream
bodyStream.Initialize("bodyStream")
bodyStream.SourceFile = "qa_data/upload.json"

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

'  The 3rd argument is the Stream that supplies the request body.
Dim responseText As String = rest.FullRequestStream("POST", "/api/upload", bodyStream)
If rest.LastMethodSuccess = False Then
    Log(rest.LastErrorText)
    Return
End If

Log(responseText)
