* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Socket')
loSocket = CreateObject('Chilkat.Socket')

* Set the certificate to be used for mutual TLS authentication
* (i.e. sets the client-side certificate for two-way TLS authentication)
* Note: There are other ways to set the client certificate using Chilkat.
* For example, on Windows systems, a Chilkat certificate object could be loaded with certificate
* pre-installed (with private key) in a Windows certificate store, and then socket.SetSslClientCert could be called.
lnSuccess = loSocket.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword")
IF (lnSuccess <> 1) THEN
    ? loSocket.LastErrorText
    RELEASE loRest
    RELEASE loSocket
    CANCEL
ENDIF

* Note: The certificate used for the client-side of TLS mutual authentication
* must have the associated private key available. (.pfx/.p12 files typically store both
* the certificate and associated private key.)

* 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
    CANCEL
ENDIF

lnBAutoReconnect = 1

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

RELEASE loRest
RELEASE loSocket
