2.sftp
2.1.sftp服务搭建
docker-compose方式搭建
version: '3'
services:
sftp:
image: atmoz/sftp
volumes:
- ./test/:/home/foo/
ports:
- "2222:22"
privileged: true
command: foo:123456:1002镜像作者的设定应该是把映射目录作为根目录（监狱），根目录（./test）是不能有写权限的，需要在下面再建一个子目录.
./test文件夹授权755，在test目录下再新建一个文件夹，比如upload, 把需要上传的文件放置在upload中，并且修改upload权限为777，例如：
mkdir upload
chmod 777 upload

测试代码如下：
