Read the REST Response Body into BinData

See more REST Examples

Demonstrates Rest.ReadRespBd, which reads the response body as raw bytes into a BinData, replacing its previous contents.

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 Long
success = 0

Dim rest As New ChilkatRest
Dim bTls As Long
bTls = 1
Dim bAutoReconnect As Long
bAutoReconnect = 1
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
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.

success = rest.SendReqNoBody("GET","/api/images/1")
If (success = 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

Dim statusCode As Long
statusCode = rest.ReadResponseHeader()
If (statusCode < 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

'  Check for the expected success status code.  If the response is not 200, the body is likely
'  error text formatted as JSON, XML, or HTML rather than the expected binary content.  In that case
'  read the body as text, report it, and return.
If (statusCode <> 200) Then
    Dim sbError As New ChilkatStringBuilder
    success = rest.ReadRespSb(sbError)
    If (success = 0) Then
        Debug.Print rest.LastErrorText
        Exit Sub
    End If

    Debug.Print "Request failed with status code " & statusCode
    Debug.Print sbError.GetAsString()
    Exit Sub
End If

'  The status code is 200.  Read the response body as raw bytes into a BinData.
Dim bdResponse As New ChilkatBinData
success = rest.ReadRespBd(bdResponse)
If (success = 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

Dim bSaved As Long
bSaved = bdResponse.WriteFile("qa_output/image.png")
If (bSaved <> 1) Then
    Debug.Print "Failed to save the response body."
    Exit Sub
End If

Debug.Print "Received " & bdResponse.NumBytes & " bytes."
