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

What I have tried:
A.
$mongofiles -h host -u user -ppasswd -d database get '/c4x/UniversityZ/CS201/asset/LC.jpg'
connected to: host
assertion: 13325 couldn't open file: /c4x/UniversityZ/CS201/asset/LC.jpg
Note: user is having "role" as "readWrite".
B,
$mongofiles -h host -u user -ppasswd -d database get 'LC.jpg'
connected to: host
ERROR: file not found
推荐答案
mongofiles -h host -u user -ppasswd -d database get'/ c4x /UniversityZ/CS201/asset/LC.jpg'
连接到：主机
断言：13325无法打开文件：/ c4x / UniversityZ / CS201 / asset / LC .jpg
注意：用户的角色为readWrite。
