Client Certificate in REST (USB Token or Smartcard)

See more REST Examples

Demonstrates how to use a client certificate with a REST connection where the certificate and private key are located on a USB token or smart card. Visual FoxPro

* 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.
loRest = CreateObject('Chilkat.Rest')
loSocket = CreateObject('Chilkat.Socket')

* Set the certificate to be used for mutual TLS authentication
loCert = CreateObject('Chilkat.Cert')

* If the smartcard or token requires a PIN...
loCert.SmartCardPin = "000000"

lnSuccess = loCert.LoadFromSmartcard("")
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

lnSuccess = loSocket.SetSslClientCert(loCert)
IF (lnSuccess <> 1) THEN
    ? loSocket.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

* Establish the connection using the socket object (with client certificate authentication).
lnBTls = 1
lnPort = 443
lnMaxWaitMs = 5000
lnSuccess = loSocket.Connect("www.example.com",lnPort,lnBTls,lnMaxWaitMs)
IF (lnSuccess <> 1) THEN
    ? "Connect Failure Error Code: " + STR(loSocket.ConnectFailReason)
    ? loSocket.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

lnBAutoReconnect = 1

* Use the connection:
lnSuccess = loRest.UseConnection(loSocket,lnBAutoReconnect)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

* At this point we are connected and can make REST calls...
* For example..
lcResponseJson = loRest.FullRequestNoBody("GET","/someQuery")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

RELEASE loRest
RELEASE loSocket
RELEASE loCert
