# package user `import "os/user"` user包允許通過名稱或ID查詢用戶帳戶。 ## Index * [type UnknownUserError](#UnknownUserError) * [func (e UnknownUserError) Error() string](#UnknownUserError.Error) * [type UnknownUserIdError](#UnknownUserIdError) * [func (e UnknownUserIdError) Error() string](#UnknownUserIdError.Error) * [type User](#User) * [func Current() (\*User, error)](#Current) * [func Lookup(username string) (\*User, error)](#Lookup) * [func LookupId(uid string) (\*User, error)](#LookupId) ## type [UnknownUserError](https://github.com/golang/go/blob/master/src/os/user/user.go#L39 "View Source") ``` type UnknownUserError string ``` 當找不到用戶時，Lookup會返回UnknownUserError ### func (UnknownUserError) [Error](https://github.com/golang/go/blob/master/src/os/user/user.go#L41 "View Source") ``` func (e UnknownUserError) Error() string ``` ## type [UnknownUserIdError](https://github.com/golang/go/blob/master/src/os/user/user.go#L31 "View Source") ``` type UnknownUserIdError int ``` 當找不到用戶時，LookupId會返回UnknownUserIdError ### func (UnknownUserIdError) [Error](https://github.com/golang/go/blob/master/src/os/user/user.go#L33 "View Source") ``` func (e UnknownUserIdError) Error() string ``` ## type [User](https://github.com/golang/go/blob/master/src/os/user/user.go#L21 "View Source") ``` type User struct { Uid string // 用戶ID Gid string // 初級組ID Username string Name string HomeDir string } ``` User代表一個用戶帳戶。 在posix系統中Uid和Gid字段分別包含代表uid和gid的十進制數字。在windows系統中Uid和Gid包含字符串格式的安全標識符（SID）。在Plan 9系統中，Uid、Gid、Username和Name字段是/dev/user的內容。 ### func [Current](https://github.com/golang/go/blob/master/src/os/user/lookup.go#L8 "View Source") ``` func Current() (*User, error) ``` 返回當前的用戶帳戶。 ### func [Lookup](https://github.com/golang/go/blob/master/src/os/user/lookup.go#L14 "View Source") ``` func Lookup(username string) (*User, error) ``` 根據用戶名查詢用戶。 ### func [LookupId](https://github.com/golang/go/blob/master/src/os/user/lookup.go#L20 "View Source") ``` func LookupId(uid string) (*User, error) ``` 根據用戶ID查詢用戶。
