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

// This example uses a previously obtained access token having permission for the 
// Google Sheets scope.

// In this example, Get Google Sheets OAuth2 Access Token, the access
// token was saved to a JSON file.  This example fetches the access token from the file..
let json_token = chilkat::JsonObject::new();
let _ = json_token.load_file("qa_data/tokens/googleSheets.json").is_ok();
if !json_token.has_member("access_token") {
    println!("No access token found.");
    return;
}

let http = chilkat::Http::new();
http.set_auth_token(&json_token.string_of("access_token").unwrap_or_default());

// To append values to an existing spreadsheet, our HTTP request body will
// contain JSON in the format of a "ValueRange".  For example, the spreadsheet we'll be
// adding to in this example looks like this:

// image

// The JSON ValueRange for the cells in the above spreadsheet is:
// {
//   "range": "Sheet1!A1:B5",
//   "majorDimension": "ROWS",
//   "values": [
//     [
//       "Item",
//       "Cost"
//     ],
//     [
//       "Wheel",
//       "$20.50"
//     ],
//     [
//       "Door",
//       "$15"
//     ],
//     [
//       "Engine",
//       "$100"
//     ],
//     [
//       "Totals",
//       "$135.50"
//     ]
//   ]
// }

// This example will append 6 cells (3 rows / 2 columns).
// We'll be appending the following:
// 
// "Paint", "$100"
// "Brakes", "$100"
// "New Total", "$335.50"
// 

// The range of cells we'll be appending is A1:B5
// Therefore, the ValueRange JSON we'll be sending in our POST body is:

// {
//   "range": "Sheet1!A1:B5",
//   "majorDimension": "ROWS",
//   "values": [
//     [
//       "Paint",
//       "$100"
//     ],
//     [
//       "Brakes",
//       "$100"
//     ],
//     [
//       "New Total",
//       "$335.50"
//     ]
//   ]
// }
