Client Certificate in REST

Demonstrates how to use a client certificate with a REST connection. B4X

Dim success As Boolean = False

'  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 ChilkatRest
rest.Initialize("rest")
Dim socket As ChilkatSocket
socket.Initialize("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.
success = socket.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx", "pfxPassword")
If success <> True Then
    Log(socket.LastErrorText)
    Return
End If


'  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).
Dim bTls As Boolean = True
Dim port As Int = 443
Dim maxWaitMs As Int = 5000

    Log("Connect Failure Error Code: " & socket.ConnectFailReason)
    Log(socket.LastErrorText)

End If


Dim bAutoReconnect As Boolean = True

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


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