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

# Get the previously obtained access token.
# See Get Google Photos Access Token.

jsonToken = Chilkat::CkJsonObject.new()
success = jsonToken.LoadFile("qa_data/tokens/googlePhotos.json")
if (success == false)
    print jsonToken.lastErrorText() + "\n";
    exit
end

http = Chilkat::CkHttp.new()

http.put_AuthToken(jsonToken.stringOf("access_token"))

# Build a JSON body that looks like this:
# {
#   "albumId": "ALBUM_ID",
#   "newMediaItems": [
#     {
#       "description": "ITEM_DESCRIPTION",
#       "simpleMediaItem": {

#       }
#     }
#    , ...

# Build the above JSON:

json.UpdateString("albumId","ALBUM_ID")
json.UpdateString("newMediaItems[0].description","Photo of Penguins")
json.UpdateString("newMediaItems[0].simpleMediaItem.uploadToken","UPLOAD_TOKEN")

# resp is a CkHttpResponse
resp = http.PostJson("https://photoslibrary.googleapis.com/v1/mediaItems:batchCreate",json.emit())
if (http.get_LastMethodSuccess() == false)
    print http.lastErrorText() + "\n";
    exit
end

# Examine the response status code.  Success is indicated by a status code of 200.
print "response status code: " + resp.get_StatusCode().to_s() + "\n";

json.Load(resp.bodyStr())
json.put_EmitCompact(false)
