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

# This example connects to a REST server through an HTTP proxy.
# It will connect to the Amazon AWS service for this example.
$rest = New-Object Chilkat.Rest
$socket = New-Object Chilkat.Socket

# Set the HTTP proxy domain or IP address, and port.
$socket.HttpProxyHostname = "192.168.1.100"
$socket.HttpProxyPort = 8088

# We want to tell the socket object that we're doing HTTP over the proxy connection.
# This is because an HTTP proxy used for other protocols (IMAP, SMTP, SSH, FTP, etc.) 
# can require some internal differences in behavior (i.e. how we do things).
$socket.HttpProxyForHttp = $true

# Other properties exist for specifying a proxy login, password, and authentication method (such as NTLM),
# but these are not used in this example.

# Connect through the HTTP proxy to the Amazon AWS server for the S3 service.
$bTls = $true
$port = 443
$maxWaitMs = 5000
$success = $socket.Connect("s3.amazonaws.com",$port,$bTls,$maxWaitMs)
if ($success -ne $true) {
    $("Connect Failure Error Code: " + $socket.ConnectFailReason)
    $($socket.LastErrorText)
    exit
}

# Use the proxied TLS connection:
$success = $rest.UseConnection($socket,$true)
if ($success -ne $true) {
    $($rest.LastErrorText)
    exit
}

# Provide AWS credentials for the REST call.
$authAws = New-Object 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...
$responseXml = $rest.FullRequestNoBody("GET","/")
if ($rest.LastMethodSuccess -ne $true) {
    $($rest.LastErrorText)
    exit
}

$xml = New-Object Chilkat.Xml
$success = $xml.LoadXml($responseXml)

# Show the full XML returned.
$($xml.GetXml())

# Iterate over the buckets, showing each bucket name.
$success = $xml.FindChild2("Buckets")
if ($xml.FirstChild2() -eq $true) {
    $($xml.GetChildContent("Name"))
    while (($xml.NextSibling2() -eq $true)) {
        $($xml.GetChildContent("Name"))
    }

}

# Move the internal pointer back to the root node.
