大家好，小弟第一次發文沒有程式背景，看了幾位前輩的文章，使用Google Apps Script想要做一個有查詢跟記錄功能的機器人，目前先做了查詢的部分，if((userData.events[0].message.text) == "查詢熱量"
接著呼叫
search(e)
但是這個查詢的參數要怎麼樣再傳進去我在LINE上輸入的字呢?

//程式碼開始
var CHANNEL_ACCESS_TOKEN = "";
var spreadSheetId = "";    //試算表 ID
var sheetName = "工作表1";    //工作表名稱
var searchColumn = 2;    //搜尋第幾欄的資料
var spreadSheet = SpreadsheetApp.openById(spreadSheetId);
var sheet = spreadSheet.getSheetByName(sheetName);
var lastRow = sheet.getLastRow();
var lastColumn = sheet.getLastColumn();
var sheetData = sheet.getSheetValues(1, 1, lastRow, lastColumn);
function doPost(e) {
  var userData = JSON.parse(e.postData.contents);
  console.log(userData);
  var replyMessage = [];
  var replyContent;
  var replyToken = userData.events[0].replyToken;
  if((userData.events[0].message.text) == "查詢熱量"){replyMessage.push({type:"text", text:"開始查詢熱量~"});
  sendReplyMessage(CHANNEL_ACCESS_TOKEN, replyToken, replyMessage);}
  search(e);//這一段要怎樣再讀取LINEBOT傳進來的內容，然後去做查詢得動作呢?``
                                                 
  
  
  }
function search(e){
   var userData = JSON.parse(e.postData.contents);
  var searchResult = [];
  var replyMessage = [];
  var replyContent;
  var replyToken = userData.events[0].replyToken;
  var searchContent = userData.events[0].message.text;
  if (userData.events[0].type != "message") {return;}
  if (userData.events[0].message.type != "text") {return;}
  searchResult = sheetData.filter(function(item, index, array){
    return item[searchColumn - 1].toString() === searchContent;
  });
  for (var i = 0; i < searchResult.length; i++) {
    replyContent = sheetData[0][0] + "：" + searchResult[i][0];
    for (var j = 1; j < lastColumn; j++) {
      replyContent += "\n\n" + sheetData[0][j] + "：" + searchResult[i][j];
    }
    replyMessage.push({type:"text", text:replyContent});
    if (replyMessage.length == 5) {break;}
  }
  if (replyMessage.length == 0) {replyMessage.push({type:"text", text:"查詢不到「" + searchContent + "」的資料"});}
  sendReplyMessage(CHANNEL_ACCESS_TOKEN, replyToken, replyMessage);


}
function sendReplyMessage(CHANNEL_ACCESS_TOKEN, replyToken, replyMessage) {
  var url = "https://api.line.me/v2/bot/message/reply";
  UrlFetchApp.fetch(url, {
    "headers": {
      "Content-Type": "application/json; charset=UTF-8",
      "Authorization": "Bearer " + CHANNEL_ACCESS_TOKEN,
    },
    "method": "post",
    "payload": JSON.stringify({
      "replyToken": replyToken,
      "messages": replyMessage,
    }),
  });
}
//程式碼結束
