本程式套用新的函式HTTPSRedirect ，讓esp8266 不須透過第三方服務轉址直接寫入Google Apps Script
函式庫下載 HTTPSRedirect
Google Apps Script 端
function doGet(e) {
var CHANNEL_ACCESS_TOKEN = '你的CHANNEL_ACCESS_TOKEN';
var USERID ='你的USERID';
var params = e.parameter;
var data = params.data;
var url = "https://api.line.me/v2/bot/message/push";
var payload= { "to": USERID ,"messages": [{ "type": "text", "text": data }] };
var options = {
"method": "post",
"headers": {"content-Type": "application/json","Authorization": "Bearer "+ CHANNEL_ACCESS_TOKEN },
"payload" : JSON.stringify(payload),
"muteHttpExceptions": true};
var response = JSON.parse(UrlFetchApp.fetch(url, options).getContentText());
return ContentService.createTextOutput(1); //接收成功以後回傳"1"(類似Tingspeak)
