Retrieve a Single Contact

See more Google APIs Examples

Demonstrates how to retrieve a single contact (by contactId) for the Google Contacts API. Perl

use chilkat();

$success = 0;

# 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 = chilkat::CkJsonObject->new();
$success = $jsonToken->LoadFile("qa_data/tokens/googleContacts.json");
if ($success != 1) {
    print "Failed to load googleContacts.json" . "\r\n";
    exit;
}

$gAuth = chilkat::CkAuthGoogle->new();
$gAuth->put_AccessToken($jsonToken->stringOf("access_token"));

$rest = chilkat::CkRest->new();

# Connect using TLS.
$bAutoReconnect = 1;
$success = $rest->Connect("www.google.com",443,1,$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 = chilkat::CkStringBuilder->new();
$sbPath->Append("/m8/feeds/contacts/default/full/{contactId}");
# Get the contact having contactId = "7b1c7b6409e718a0"
$numReplacements = $sbPath->Replace("{contactId}","7b1c7b6409e718a0");

$sbResponseBody = chilkat::CkStringBuilder->new();
$success = $rest->FullRequestNoBodySb("GET",$sbPath->getAsString(),$sbResponseBody);
if ($success != 1) {
    print $rest->lastErrorText() . "\r\n";
    exit;
}

# A successful response will have a status code equal to 200.
if ($rest->get_ResponseStatusCode() != 200) {
    print "response status code = " . $rest->get_ResponseStatusCode() . "\r\n";
    print "response status text = " . $rest->responseStatusText() . "\r\n";
    print "response header: " . $rest->responseHeader() . "\r\n";
    print "response body: " . $sbResponseBody->getAsString() . "\r\n";
    exit;
}

# If the 200 response was received, then the contacts XML is contained
# in the response body.
$xml = chilkat::CkXml->new();
$xml->LoadSb($sbResponseBody,0);

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

# Now let's parse the XML...
print "title: " . $xml->getChildContent("title") . "\r\n";

$emailAddress = $xml->chilkatPath("gd:email|(address)");
if ($xml->get_LastMethodSuccess() == 1) {
    print "email address: " . $emailAddress . "\r\n";
}

# The response body XML looks something like this:

# 	<?xml version="1.0" encoding="UTF-8" ?>
