建议增加对非root用户的支持

[csquya]

这个插件很不错，可是我在上传的时候出现了错误，我初步分析了认为是权限问题， 因为我使用了非root用户。

ssh 远程登陆一般都不是root， 但是很多非root用户可以用 sudo免密进行scp 等操作。

所以我建议增加非root用户的支持， 类似于ansible里有个参数 become:yes, 不知道是否可行。

谢谢。

不过我用了以下办法也不行啊，还是提示无权限， 尽管我认为解决了权限问题

先

mkdir /home/myname/picgo
sudo ln -s  /home/myname/picgo /xxx/xxx/wp-content/uploads/picgo/
sudo chown myname:www-data -R /xxx/xxx/wp-content/uploads/picgo/

然后

{
  "Wordpress": {
    "url": "https://mydomain.com",
    "path": "/wp-content/uploads/picgo/{year}/{month}/{fullName}",
    "uploadPath": "/home/myname/picgo/{year}/{month}/{fullName}",
    "host": "m.y.i.p",
    "port": 22,
    "username": "myname",
    "privateKey": "C:/Users/myname/.ssh/id_rsa",
    "fileUser": "www-data:www-data",
	"dirMode": "0755"
  }
}

贴一下错误日志， 似乎路径有问题，但是我看不出来

出问题的是大概是以下语句

        path: userConfig.path,
        uploadPath: userConfig.uploadPath

补充下 sftp myname@myhost 用密钥登陆是成功的， ls 命令下 也能正确看到 /home/myname/picgo的目录， 而且 mkdir 也能产生目录
