HtmlService
Service permettant de renvoyer du contenu HTML et d'autres contenus textuels à partir d'un script.
Pour des raisons de sécurité, les scripts ne peuvent pas renvoyer directement de contenu à un navigateur. Au lieu de cela, ils doivent nettoyer le code HTML afin qu'il ne puisse pas effectuer d'actions malveillantes. Consultez la description de HtmlOutput pour connaître les limites concernant les éléments pouvant être renvoyés.
Obtient la chaîne user-agent du navigateur actuel. Renvoie null pour la plupart des exécutions de script s'il n'est pas utilisé dans la fonction doGet() ou doPost() d'une application Web.
