使用Google雲端儲存上傳圖片
谷歌雲端儲存官網：https://console.cloud.google.com/
1.獲取服務賬號金鑰：官網--左側導航API和服務--憑據--建立服務賬號金鑰
2.將下載的Json檔案配置到環境變數(配置完成後重啟電腦)
A.Windows:
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
B.Linux:
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
set GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
export GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
