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

http = chilkat2.Http()
http.AuthToken = "GMAIL-ACCESS-TOKEN"

# The id of the GMail message to download.
id = "166e50fed0b9b0cb"
userId = "me"

http.SetUrlVar("userId","me")
http.SetUrlVar("id",id)

# Fetch the email.
url = "https://www.googleapis.com/gmail/v1/users/{$userId}/messages/{$id}?format=raw"
sbJson = chilkat2.StringBuilder()
success = http.DownloadSb(url,"utf-8",sbJson)
if (success != True):
    print(http.LastErrorText)
    sys.exit()

json.LoadSb(sbJson)
json.EmitCompact = False

if (http.LastStatus != 200):
    print(json.Emit())
    print("Failed.")
    sys.exit()

# The returned JSON contains something like this:

# {
#   "id": "166e50fed0b9b0cb",
#   "threadId": "166e50fed0b9b0cb",

#   "raw": "BASE64URL_CONTENT"

# The RFC822 MIME of the email is contained in the "raw" as a base64URL encoded string.
# Let's decode and load into a Chilkat email object..

# Now we can use the email API to do whatever we desire..
print("From: " + email.FromAddress)
print("Subject: " + email.Subject)
