conten t_son:{

类别:资产,

},

文件名:/ c4x/UniversityZ/CS201/asset/LC.jpg,

displayname:LC .jpg,

length:NumberInt(178417),

import_path:null,

uploadDate:ISODate( 2017-04-13T12:34:16.436Z),

thumbnail_location:[

UniversityZ,

CS201,

缩略图,

LC.jpg,

null

],

md5:da3518a71e1fffb9afc5bf42c840086b

}



我尝试过:



A.

$ mongofiles -h host -u user -ppasswd -d database get' /c4x/UniversityZ/CS201/asset/LC.jpg'

关联:主人

断言:13325 cou不打开文件:/c4x/UniversityZ/CS201/asset/LC.jpg



注意:用户的角色为readWrite。



B,

$ mongofiles -h host -u user -ppasswd -d database get'LC.jpg'

连接到:主机

错误:找不到文件
