用命令行从Google Drive中下载目录
首先需要创建 Google 服务账号，并生成 JSON 格式的密钥。将该密钥文件保存到“~/.gdrive”目录中。
安装 go 语言。
yum install golang
将 go 配置到 PATH 环境变量中。在“~/.bashrc”加“export PATH=~/go/bin:$PATH”。
安装 gdrive。
go get github.com/prasmussen/gdrive
尝试下载目录。
# gdrive download --service-account Google服务账户密钥.json --recursive 1NAs78a38xkl1MhodoD7BM0Lh3v_sFwYs Failed to get file: googleapi: Error 403: Project 1001876711724 is not found and cannot be used for API calls.
