在golang中实现接口给出了具有指针接收器的方法

我在Golang工作,我试图使用接口来组合一组使用类似方法的结构.简而言之,我有这个:

type Person interface {
    BasicInfo() MemberBasicInfo
}

type MemberBasicInfo struct {
    ID                         uint       
    MemberFirstName            string     
    MemberNickname             string     
    MemberEmail                string    
}

然后,应该作为接口的结构:

func (member *Member) BasicInfo() MemberBasicInfo{
    return MemberBasicInfo{
        ID: member.ID,
        ...other mapping here...
    }
}

func (user *User) BasicInfo() MemberBasicInfo{
    return MemberBasicInfo{
        ID: uint(user.ID),
        ...other mapping here...
    }
}

cannot use memberData (type Member) as type Member.Person in return argument: Member does not implement Person (BasicInfo method has pointer receiver)
cannot use memberData (type User) as type Person in return argument: User does not implement Person (BasicInfo method has pointer receiver)

我错过了什么？或者我做错了什么？

如果您的接口声明如下:

type Person interface {
    BasicInfo() MemberBasicInfo
}

BasicInfo() MemberBasicInfo

在您的情况下,您创建了此方法:

func (member *Member) BasicInfo() MemberBasicInfo

*Member

*Member*Member

因此,在尝试将类型分配给接口变量时,请确保使用指针而不是直接值.

这应该工作:

var p Person
p = &Member{}

但这不会:

var p Person
p = Member{}
