// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example shows how to use the Chilkat socket object's connection.
Dim rest As New Chilkat.Rest
Dim socket As New Chilkat.Socket

// Set the certificate to be used for mutual TLS authentication
Dim cert As New Chilkat.Cert

// If the smartcard or token requires a PIN...
cert.SmartCardPin = "000000"

Dim success As Boolean
success = cert.LoadFromSmartcard("")
If (success <> True) Then
    System.DebugLog(cert.LastErrorText)
    Return
End If

success = socket.SetSslClientCert(cert)
If (success <> True) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

// Establish the connection using the socket object (with client certificate authentication).
Dim bTls As Boolean
bTls = True
Dim port As Int32
port = 443
Dim maxWaitMs As Int32
maxWaitMs = 5000
success = socket.Connect("www.example.com",port,bTls,maxWaitMs)
If (success <> True) Then
    System.DebugLog("Connect Failure Error Code: " + Str(socket.ConnectFailReason))
    System.DebugLog(socket.LastErrorText)
    Return
End If

Dim bAutoReconnect As Boolean
bAutoReconnect = True

// Use the connection:
success = rest.UseConnection(socket,bAutoReconnect)
If (success <> True) Then
    System.DebugLog(rest.LastErrorText)
    Return
End If

// At this point we are connected and can make REST calls...
// For example..
Dim responseJson As String
responseJson = rest.FullRequestNoBody("GET","/someQuery")
If (rest.LastMethodSuccess <> True) Then
    System.DebugLog(rest.LastErrorText)
