(VB.NET) REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls.

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

Dim tunnel As New Chilkat.Socket

Dim sshHostname As String = "sftp.example.com"
Dim sshPort As Integer = 22

' Connect to an SSH server and establish the SSH tunnel:
Dim success As Boolean = tunnel.SshOpenTunnel(sshHostname,sshPort)
If (success <> True) Then
    Debug.WriteLine(tunnel.LastErrorText)
    Exit Sub
End If


' Authenticate with the SSH server via a login/password
' or with a public key.
' This example demonstrates SSH password authentication.
success = tunnel.SshAuthenticatePw("mySshLogin","mySshPassword")
If (success <> True) Then
    Debug.WriteLine(tunnel.LastErrorText)
    Exit Sub
End If


'  OK, the SSH tunnel is setup.  Now open a channel within the tunnel.
'  (Any number of channels may be created from the same SSH tunnel.
'  Multiple channels may coexist at the same time.)

' This example connects to a REST server through the SSH tunnel.
' It will connect to the Amazon AWS service for this example.
Dim rest As New Chilkat.Rest
Dim channel As Chilkat.Socket

Dim bTls As Boolean = True
Dim port As Integer = 443
Dim maxWaitMs As Integer = 5000

' This returns a socket object that is a single channel within the SSH tunnel.
channel = tunnel.SshOpenChannel("s3.amazonaws.com",port,bTls,maxWaitMs)
If (tunnel.LastMethodSuccess <> True) Then
    Debug.WriteLine(tunnel.LastErrorText)
    Exit Sub
End If


' Use the connection.  (This connection is a TLS running on an SSH channel through an SSH tunnel.
' In other words, TLS is wrapped within the SSH tunnel.)
success = rest.UseConnection(channel,True)
If (success <> True) Then
    Debug.WriteLine(rest.LastErrorText)

    Exit Sub
End If


' Provide AWS credentials for the REST call.
Dim authAws As New Chilkat.AuthAws
authAws.AccessKey = "AWS_ACCESS_KEY"
authAws.SecretKey = "AWS_SECRET_KEY"
authAws.ServiceName = "s3"
success = rest.SetAuthAws(authAws)

' List all buckets for the account...
Dim responseXml As String = rest.FullRequestNoBody("GET","/")
If (rest.LastMethodSuccess <> True) Then
    Debug.WriteLine(rest.LastErrorText)

    Exit Sub
End If


Dim xml As New Chilkat.Xml
success = xml.LoadXml(responseXml)

' Show the full XML returned.
Debug.WriteLine(xml.GetXml())

' Iterate over the buckets, showing each bucket name.
success = xml.FindChild2("Buckets")
If (xml.FirstChild2() = True) Then
    Debug.WriteLine(xml.GetChildContent("Name"))
    While (xml.NextSibling2() = True)
        Debug.WriteLine(xml.GetChildContent("Name"))
    End While
End If

' Move the internal pointer back to the root node.
xml.GetRoot2()
