این صفحه شامل مثالهایی از نحوه استفاده از کتابخانههای کلاینت Places Aggregate API است.
کتابخانههای کلاینت را نصب کنید
برای دستورالعملهای نصب ، به کتابخانههای کلاینت Places Aggregate API مراجعه کنید.
احراز هویت
وقتی از کتابخانههای کلاینت استفاده میکنید، از اعتبارنامههای پیشفرض برنامه (ADC) برای احراز هویت استفاده میکنید. برای اطلاعات بیشتر در مورد راهاندازی ADC، به «ارائه اعتبارنامه برای اعتبارنامههای پیشفرض برنامه » مراجعه کنید. برای اطلاعات بیشتر در مورد استفاده از ADC با کتابخانههای کلاینت، به «احراز هویت با استفاده از کتابخانههای کلاینت» مراجعه کنید.
همچنین میتوانید از کلیدهای API برای احراز هویت در کتابخانههای کلاینت استفاده کنید، برای مثال:

هنگام استفاده از کلیدهای API در برنامههای خود، مطمئن شوید که آنها در طول ذخیرهسازی و انتقال ایمن نگه داشته میشوند. افشای عمومی کلیدهای API شما میتواند منجر به هزینههای غیرمنتظرهای از حساب شما شود.
مثالهای این صفحه از اعتبارنامههای پیشفرض برنامه استفاده میکنند.
