在Twitter App中使用Google表格

Question

我有一个Google表格可以通过Twitter发送消息，我已经在Twitter中创建了我的应用程序，并使用了使用者和密钥，如果我没有回调URL进行设置，就会收到一条错误消息，告诉我与桌面应用程序不兼容。

如果我输入一个占位符回调URL，则会出现以下错误：

错误：启动OAuth流时出错：此客户端应用程序未批准回调URL。可以在您的应用程序设置中调整批准的回调URL

我应该使用什么作为回调URL？

这是代码：

function help_() {
  var html = HtmlService.createHtmlOutputFromFile('help')
  .setTitle("Google Scripts Support")
  .setWidth(400)
  .setHeight(200);
  var ss = SpreadsheetApp.getActive();
  ss.show(html);
}

function promo_() {
  var html = HtmlService.createHtmlOutputFromFile('promo')
  .setTitle("Twitter Merge Complete")
  .setWidth(450)
  .setHeight(260);
  var ss = SpreadsheetApp.getActive();
  ss.show(html);
}

function getTwitterService_() {

  var consumer_key = "xxxxxxxxxxxxxxxxxxxx";
  var consumer_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";

  return OAuth1.createService('twitter')
  .setAccessTokenUrl('https://api.twitter.com/oauth/access_token')
  .setRequestTokenUrl('https://api.twitter.com/oauth/request_token')
  .setAuthorizationUrl('https://api.twitter.com/oauth/authorize')
  .setConsumerKey(consumer_key)
  .setConsumerSecret(consumer_secret)
  .setCallbackFunction('twitter')
  .setPropertyStore(PropertiesService.getUserProperties());

}

function twitter(request) {
  var twitterService = getTwitterService_();
  var isAuthorized = twitterService.handleCallback(request);
  if (isAuthorized) {
    return HtmlService.createHtmlOutput('<br><p style="text-align:center">Success! Your Twitter account is now authorized. Please close this window.</p>');
  } else {
    return HtmlService.createHtmlOutput('<br><p style="text-align:center">Ah! there was an error. Please contact Amit Agarwal amit@labnol.org for support (or tweet @labnol)</p>');
  }
}

function clearService(){
  OAuth1.createService('twitter')
  .setPropertyStore(PropertiesService.getUserProperties())
  .reset();
}

function encodeString_(q) {

    var str = encodeURIComponent(q
        .replace(/&(gt|lt|amp);/g, function(str, code) {
            var lookup = {
                gt: ">",
                lt: "<",
                amp: "&"
            }
            return lookup[code];
        })).replace(/[()\[\]!*']/g, function(badchar) {
        return "%" + badchar.charCodeAt(0).toString(16);
    });
    return str;  

  // return encodeURIComponent(q).replace(/\!/g, "%21").replace(/\*/g, "%2A").replace(/\'/g, "%27").replace(/\(/g, "%28").replace(/\)/g, "%29");

}

function doProperty_(key, value) {

  var properties = PropertiesService.getUserProperties();

  if (value) {
    properties.setProperty(key, value);
  } else {
    return properties.getProperty(key) || "";
  }

}


function onOpen() {

  var menu, ss = SpreadsheetApp.getActiveSpreadsheet();

  menu = [
    { name: "1. Authorize Twitter", functionName: "authTwitter_"},
    { name: "2. Configure Tweets",  functionName: "configTwitter_"},
    { name: "3. Send Tweets",  functionName: "sendTweets_"},
    null,
    { name: "Help & Support",   functionName:  "help_"},
  ];  

    ss.addMenu("  Twitter Merge", menu);

    }
