Whats is the usage of SHA1 fingerprint in google map api

在 google api 控制台中添加 SHA1 指纹的原因是什么?

它用于唯一标识您的应用程序。来自 the documentation:

The Maps API key is based on a short form of your application's digital certificate, known as its SHA-1 fingerprint. The fingerprint is a unique text string generated from the commonly-used SHA-1 hashing algorithm. Because the fingerprint is itself unique, Google Maps uses it as a way to identify your application.
