# See Global Unlock Sample for sample code.

# Use the Chilkat Email API to create or load an email.
$email = chilkat::CkEmail->new();

# The From name/address don't need to be specified. 
# GMail will automatically use your Gmail address if the following 2 lines are omitted.
$email->put_FromName("My Name");
$email->put_FromAddress('my_account_name@gmail.com');

$email->AddTo("John Smith",'somebody@somewhere.com');
# To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

$email->put_Subject("This is a test GMail email created using Chilkat.");
$email->put_Charset("utf-8");
$email->AddPlainTextAlternativeBody("This is a test");

# Create an HTML email body with an embedded image.
$cid = $email->addRelatedFile("qa_data/jpg/starfish.jpg");
$sbHtml = chilkat::CkStringBuilder->new();
$sbHtml->Append("<html><body>This is a <b>test</b><br><img src=\"cid:STARFISH_CID\"/></body></html>");
$numReplacements = $sbHtml->Replace("STARFISH_CID",$cid);

$email->AddHtmlAlternativeBody($sbHtml->getAsString());

# OK.. we now have an HTML email with an embedded JPG image
# We'll need to get the full MIME of the email encoded to a base64url string.
$sbMime = chilkat::CkStringBuilder->new();
$email->GetMimeSb($sbMime);
$sbMime->Encode("base64url","utf-8");

# The body of the HTTP request will be JSON..
$json = chilkat::CkJsonObject->new();
$json->UpdateSb("raw",$sbMime);

# Send the email...
$http = chilkat::CkHttp->new();
$http->put_AuthToken("GMAIL-ACCESS-TOKEN");

$url = "https://www.googleapis.com/gmail/v1/users/me/messages/send";
# resp is a HttpResponse
$resp = $http->PostJson3($url,"application/json",$json);
if ($http->get_LastMethodSuccess() != 1) {
    print $http->lastErrorText() . "\r\n";

# A status code of 200 indicates success.
print "Response status code: " . $resp->get_StatusCode() . "\r\n";
print "Response body:" . "\r\n";
print $resp->bodyStr() . "\r\n";

# The response body contains JSON.
# Use the online tool at Generate JSON Parsing Code
# to generate JSON parsing code.

# A sample successful JSON response:

#  "threadId": "166f0d4ac39e50bf",
#  "labelIds": [
