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

# Use the Chilkat Email API to create or load an email.
email = Chilkat::CkEmail.new()
email.put_Subject("This is a test GMail email created using Chilkat.")
email.put_Charset("utf-8")
email.AddPlainTextAlternativeBody("This is a test")
email.AddHtmlAlternativeBody("<html><body><p>This is a <b>test</b></body></html>")

# 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("message.raw",sbMime)

# Upload the email to GMail as a draft.
http = Chilkat::CkHttp.new()
http.put_AuthToken("GMAIL-ACCESS-TOKEN")

url = "https://www.googleapis.com/gmail/v1/users/me/drafts"
# resp is a CkHttpResponse
resp = http.PostJson3(url,"application/json",json)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    exit
end

# A status code of 200 indicates success.
print "Response status code: " + resp.get_StatusCode().to_s() + "\n";
print "Response body:" + "\n";
print resp.bodyStr() + "\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:

# {
#  "id": "r-2607584557788895307",
#  "message": {
#   "id": "166f09932c662e93",
