تنفيذ الدوال باستخدام واجهة برمجة التطبيقات لبرمجة التطبيقات

النص البرمجي المستهدف

تستخدم الدالة في هذا النص البرمجي Drive API.

عليك تفعيل Drive API في المشروع الذي يستضيف النص.

بالإضافة إلى ذلك، يجب أن ترسل تطبيقات الاتصال بيانات اعتماد OAuth التي تشمل نطاق Drive التالي:

• https://www.googleapis.com/auth/drive

تستخدم نماذج التطبيقات هنا مكتبات عملاء Google لإنشاء كائنات بيانات الاعتماد لـ OAuth باستخدام هذا النطاق.
