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

# --------------------------------------------------------------------------------------------------------
# Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
# Once connected, the REST object may be re-used for many REST API calls.
# (It's a good idea to put the connection setup code in a separate function/subroutine.)
# --------------------------------------------------------------------------------------------------------

# It is assumed we previously obtained an OAuth2 access token.
# This example loads the JSON access token file 
# saved by this example: Get Google Contacts OAuth2 Access Token

$jsonToken = New-Object Chilkat.JsonObject
$success = $jsonToken.LoadFile("qa_data/tokens/googleContacts.json")
if ($success -ne $true) {
    $("Failed to load googleContacts.json")
    exit
}

$gAuth = New-Object Chilkat.AuthGoogle
$gAuth.AccessToken = $jsonToken.StringOf("access_token")

$rest = New-Object Chilkat.Rest

# Connect using TLS.
$bAutoReconnect = $true
$success = $rest.Connect("www.google.com",443,$true,$bAutoReconnect)

# Provide the authentication credentials (i.e. the access token)
$rest.SetAuthGoogle($gAuth)

# ----------------------------------------------
# OK, the REST connection setup is completed..
# ----------------------------------------------

# To retrieve the contact, send the following:

# 	GET /m8/feeds/contacts/default/full/{contactId}
# 	GData-Version: 3.0

$rest.AddHeader("GData-Version","3.0")

$sbPath = New-Object Chilkat.StringBuilder
$sbPath.Append("/m8/feeds/contacts/default/full/{contactId}")
# Get the contact having contactId = "7b1c7b6409e718a0"
$numReplacements = $sbPath.Replace("{contactId}","7b1c7b6409e718a0")

$sbResponseBody = New-Object Chilkat.StringBuilder
$success = $rest.FullRequestNoBodySb("GET",$sbPath.GetAsString(),$sbResponseBody)
if ($success -ne $true) {
    $($rest.LastErrorText)
    exit
}

# A successful response will have a status code equal to 200.
if ($rest.ResponseStatusCode -ne 200) {
    $("response status code = " + $rest.ResponseStatusCode)
    $("response status text = " + $rest.ResponseStatusText)
    $("response header: " + $rest.ResponseHeader)
    $("response body: " + $sbResponseBody.GetAsString())
    exit
}

# If the 200 response was received, then the contacts XML is contained
# in the response body.
$xml = New-Object Chilkat.Xml
$xml.LoadSb($sbResponseBody,$false)

# See below for a sample response body.
$xml.SaveXml("qa_output/google_contact.xml")

# Now let's parse the XML...
$("title: " + $xml.GetChildContent("title"))

$emailAddress = $xml.ChilkatPath("gd:email|(address)")
if ($xml.LastMethodSuccess -eq $true) {
    $("email address: " + $emailAddress)
}

# The response body XML looks something like this:
