Download a Binary REST Response into BinData

Demonstrates Rest.FullRequestNoBodyBd, which sends a request with no body and stores the binary response body in a BinData.

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 New Chilkat.Rest
Dim bTls As Boolean = True
Dim bAutoReconnect As Boolean = True
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = False) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If

'  FullRequestNoBodyBd sends a request with no body and stores the binary response body in a
'  BinData.  This is appropriate when the response is binary, such as an image or file download.
Dim bdResponse As New Chilkat.BinData
success = rest.FullRequestNoBodyBd("GET","/api/images/1",bdResponse)
If (success = False) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


Dim bSaved As Boolean = bdResponse.WriteFile("qa_output/image.png")
If (bSaved <> True) Then
    Debug.WriteLine("Failed to save the response body.")
    Exit Sub
End If

Debug.WriteLine("Downloaded " & bdResponse.NumBytes & " bytes.")
