' 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.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Email")
set email = Server.CreateObject("Chilkat.Email")

' 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.FromName = "My Name"
email.FromAddress = "my_account_name@gmail.com"

success = email.AddTo("John Smith","somebody@somewhere.com")
' To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

email.Subject = "This is a test GMail email created using Chilkat."
email.Charset = "utf-8"
success = email.AddPlainTextAlternativeBody("This is a test")

' Create an HTML email body with an embedded image.
cid = email.AddRelatedFile("qa_data/jpg/starfish.jpg")
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sbHtml = Server.CreateObject("Chilkat.StringBuilder")
success = sbHtml.Append("<html><body>This is a <b>test</b><br><img src=""cid:STARFISH_CID""/></body></html>")
numReplacements = sbHtml.Replace("STARFISH_CID",cid)

success = 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.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sbMime = Server.CreateObject("Chilkat.StringBuilder")
success = email.GetMimeSb(sbMime)
success = sbMime.Encode("base64url","utf-8")

' The body of the HTTP request will be JSON..
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = Server.CreateObject("Chilkat.JsonObject")
success = json.UpdateSb("raw",sbMime)

' Send the email...
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = Server.CreateObject("Chilkat.Http")
http.AuthToken = "GMAIL-ACCESS-TOKEN"

url = "https://www.googleapis.com/gmail/v1/users/me/messages/send"
' resp is a Chilkat.HttpResponse
Set resp = http.PostJson3(url,"application/json",json)
If (http.LastMethodSuccess <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>"

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