Authentication

Community-Connectors unterstützen die folgenden Authentifizierungsmethoden:

  • oauth 2.0
  • Pfad/Nutzername/Passwort
  • Pfad/Schlüssel
  • Nutzername/Passwort
  • Nutzername/Token
  • Schlüssel
  • Keine

Je nach verwendeter Methode müssen Sie in Ihrem Connector zusätzliche Funktionen bereitstellen.

In der folgenden Tabelle sehen Sie, welche Funktionen Sie je nach Authentifizierungstyp Ihres Connectors definieren müssen.

isAuthValid()

Diese Funktion wird aufgerufen, um festzustellen, ob die Authentifizierung für den Drittanbieterdienst gültig ist. Wenn die Authentifizierung gültig ist, sollten Aufrufe von getData() und getSchema() nicht aufgrund von unberechtigtem Zugriff fehlschlagen. Wenn die Autorisierung nicht gültig ist, erhält der Nutzer möglicherweise eine Benachrichtigung, den Autorisierungsvorgang zu starten.

OAUTH2

OAuth2 für Apps Script-Bibliothek hinzufügen und einrichten

Folgen Sie der Einrichtungsanleitung für die OAuth2 for Apps Script-Bibliothek, um sie Ihrem Connector-Projekt hinzuzufügen. Folgen Sie dann dem ersten Schritt im Leitfaden, um einen OAuth2-Dienst in Ihrem Connector-Projekt zu erstellen. Ihr OAuth2-Dienst kann einen beliebigen gültigen Funktionsnamen haben. Achten Sie jedoch darauf, dass Sie denselben Namen verwenden, wenn Sie in Ihrem Code auf den OAuth2-Dienst verweisen.

Beispiel: Ein OAuth2-Dienst namens exampleService:

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()

Diese Funktion wird aufgerufen, um den OAuth 2.0-Vorgang abzuschließen. Die Callback-Antwort vom Drittanbieter-Authentifizierungsdienst wird als Argument bereitgestellt und sollte von dieser Funktion verarbeitet werden.

Beispiel für die Verarbeitung des OAuth 2.0-Callbacks mit der OAuth2 for Apps Script-Bibliothek:

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()

Diese Funktion wird aufgerufen, um die URL abzurufen, die zum Starten des Autorisierungsablaufs für den Drittanbieterdienst erforderlich ist. Wenn isAuthValid den Wert false zurückgibt, wird die zurückgegebene URL dem Nutzer als Schaltfläche oder Link angezeigt, damit er den Zugriff auf den Drittanbieterdienst autorisieren kann. Weitere Informationen finden Sie in der Referenz zu get3PAuthorizationUrls().

Beispiel für die Rückgabe der Autorisierungs-URL mit der OAuth2 for Apps Script-Bibliothek:

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 und PATH_KEY

Das Folgende ist nur für die Authentifizierungsabläufe USER_PASS, USER_TOKEN, KEY, PATH_USER_PASS und PATH_KEY erforderlich.

setCredentials()

setCredentials wird aufgerufen, nachdem der Nutzer seine Anmeldedaten auf der Konfigurationsseite des Community-Connectors eingegeben hat. Sie sollten den Properties Service verwenden, um die Anmeldedaten mit UserProperties pro Nutzer zu speichern.

PATH_USER_PASS

/**
 * Sets the credentials.
 * @param {Request} request The set credentials request.
 * @return {object} An object with an errorCode.
 */
function setCredentials(request) {
  var creds = request.pathUserPass;

  // a call to your service. You would have to have a `checkForValidCreds`
  // function defined for this to work.
