驗證

社群連接器支援下列驗證方法：

  • OAuth 2.0
  • 路徑/使用者名稱/密碼
  • 路徑/金鑰
  • 使用者名稱/密碼
  • 使用者名稱/權杖
  • 鍵
  • 無

視您使用的方法而定，您必須提供額外函式。 。

下表指出您必須根據 驗證類型

getAuthType() 必填 必填 必填
resetAuth() 必填 必填
isAuthValid() 必填 必填

isAuthValid()

系統會呼叫此函式來判斷第三方是否進行驗證 服務有效。如果驗證有效，則應該呼叫 getData() 和 getSchema() 不會失敗，原因如下： 未經授權存取。如果驗證無效，使用者可能會收到 開始授權流程的通知。

OAUTH2

data-studio/auth.gs
/**
 * Returns true if the auth service has access.
 * @return {boolean} True if the auth service has access.
 */
function isAuthValid() {
  return getOAuthService().hasAccess();
}

PATH_USER_PASS

/**

 * @return {boolean} True if the auth service has access.
 */
function isAuthValid() {
  var userProperties = PropertiesService.getUserProperties();
  var path = userProperties.getProperty('dscc.path');
  var userName = userProperties.getProperty('dscc.username');
  var password = userProperties.getProperty('dscc.password');
  // This assumes you have a validateCredentials function that
  // can validate if the path, userName and password are correct.
  return validateCredentials(path, userName, password);
}

PATH_KEY

/**
 * Returns true if the auth service has access.
 * @return {boolean} True if the auth service has access.
 */
function isAuthValid() {
  var userProperties = PropertiesService.getUserProperties();
  var path = userProperties.getProperty('dscc.path');
  var key = userProperties.getProperty('dscc.key');
  // This assumes you have a validateCredentials function that
  // can validate if the path and key are correct.
  return validateCredentials(path, key);
}

USER_PASS

data-studio/auth.gs
/**
 * Returns true if the auth service has access.
 * @return {boolean} True if the auth service has access.
 */
function isAuthValid() {
  var userProperties = PropertiesService.getUserProperties();
  var userName = userProperties.getProperty('dscc.username');
  var password = userProperties.getProperty('dscc.password');
  // This assumes you have a validateCredentials function that
  // can validate if the userName and password are correct.
  return validateCredentials(userName, password);
}

USER_TOKEN

data-studio/auth.gs
/**

 * @return {boolean} True if the auth service has access.
 */
function isAuthValid() {
  var userProperties = PropertiesService.getUserProperties();
  var userName = userProperties.getProperty('dscc.username');
  var token = userProperties.getProperty('dscc.token');
  // This assumes you have a validateCredentials function that
  // can validate if the userName and token are correct.
  return validateCredentials(userName, token);

  var key = userProperties.getProperty('dscc.key');
  // This assumes you have a validateKey function that can validate
  // if the key is valid.
  return validateKey(key);
}

OAUTH2

新增並設定 Apps Script 程式庫的 OAuth2

按照 Apps Script 的 OAuth2 設定操作說明進行 即可加入連接器專案。接著，按照 使用指南，在連接器中建立 OAuth2 服務 專案。您的 OAuth2 服務可以具有任何有效的函式名稱，但請務必 在程式碼中參照 OAuth2 服務時，使用相同的名稱。

例如，名為 exampleService 的 OAuth2 服務：

data-studio/auth.gs
/**
 * Returns the configured OAuth Service.
 * @return {Service} The OAuth Service
 */
function getOAuthService() {
  return OAuth2.createService('exampleService')
      .setAuthorizationBaseUrl('...')
      .setTokenUrl('...')
      .setClientId('...')
      .setClientSecret('...')
      .setPropertyStore(PropertiesService.getUserProperties())
      .setCallbackFunction('authCallback')
      .setScope('...');
};

authCallback()

呼叫此函式即可完成 OAuth 2.0 流程。回呼回應 則來自第三方驗證服務的結果 由此函式處理

使用 Apps Script 的 OAuth2 處理 OAuth 2.0 回呼的範例 程式庫：

data-studio/auth.gs
/**
 * The OAuth callback.
 * @param {object} request The request data received from the OAuth flow.
 * @return {HtmlOutput} The HTML output to show to the user.
 */
function authCallback(request) {
  var authorized = getOAuthService().handleCallback(request);
  if (authorized) {
    return HtmlService.createHtmlOutput('Success! You can close this tab.');
  } else {
    return HtmlService.createHtmlOutput('Denied. You can close this tab');
  };
};

get3PAuthorizationUrls()

系統會呼叫此函式，取得啟動驗證所需的網址 第三方服務流程如果 isAuthValid 傳回 false，則網址 系統將以按鈕或連結的形式向使用者顯示，方便他們 授權存取第三方服務。請參閱 get3PAuthorizationUrls()。

使用 Apps Script 的 OAuth2 傳回授權網址的範例 程式庫：

data-studio/auth.gs
/**
 * Gets the 3P authorization URL.
 * @return {string} The authorization URL.
 * @see https://developers.google.com/apps-script/reference/script/authorization-info
 */
function get3PAuthorizationUrls() {
  return getOAuthService().getAuthorizationUrl();
}

USER_PASS、USER_TOKEN、KEY、PATH_USER_PASS以及PATH_KEY

以下項目只有 USER_PASS、USER_TOKEN、KEY 和 PATH_USER_PASS 和 PATH_KEY 驗證流程。

setCredentials()

使用者輸入憑證後，系統會呼叫 setCredentials 請參閱社群連接器設定頁面的資訊。您應該使用 屬性服務：儲存每位使用者的憑證 使用 UserProperties。

PATH_USER_PASS

/**
 * Sets the credentials.
 * @param {Request} request The set credentials request.
 * @return {object} An object with an errorCode.

  var creds = request.pathUserPass;

  var validCreds = checkForValidCreds(path, username, password);
  if (!validCreds) {
