var data = Utilities.newBlob("THis is blob data", MimeType.PLAIN_TEXT, 'test.txt');

if (  ?? ) then Logger.log('yes, this is blob') ;

如何检测数据是blob？（不是对象）

instanceof Blob
// or
instanceof BlobSource

结果：ReferenceError：Blob或BlobSource未定义

instanceof GoogleAppsScript.Base.Blob;
// ReferenceError: `GoogleAppsScript` is not defined

typeof data
// result: object

Object.prototype.toString.call(data);
// result: [object Object]
