minio
minio
1. 使用下列文件开启服务
2. 修改密码及开启服务
第一步，找到minio.exe所在目录，进入cmd窗口。
第二步，输入set MINIO_ACCESS_KEY=admin命令，修改ACCESS-KEY。
第三步，输入set MINIO_SECRET_KEY=12345678命令，修改 SECRET-KEY。
第四步，输入minio.exe server D:\minio，启动minio。
3.说明
4.操作类

# 文件地址
file_path = r'E:\workspace\project\tools\tools\pdf\明天.pdf'
# 打开文件
with open(file_path, 'rb') as file:
# 读取文件流
content = file.read()
# 获取文件大小
file_size = os.path.getsize(file_path)
# 根据配置字典连接minio
minio_vessel = MinioOss(**MINIO_CONF)
# 上传本地文件
minio_vessel.upload_file('folder/明天.pdf',r'E:\workspace\project\tools\tools\pdf\明天.pdf')
# 上传文件流
minio_vessel.upload('folder/明天.pdf',content,file_size)
# 获取预览地址
