我有一个struct在user呼包account

type Account struct {
    Tp          string `json:"type"bson:"type"`
    AccountId   string  `json:"account_id"bson:"account_id"`
    Credentials map[string]interface{} `json:"credentials,omitempty"bson:"credentials,omitempty"`
    ProfilePicture string `json:"profile_picture,omitempty"`
    Username string `json:"username"bson:"username"`
    AccessToken map[string]interface{}`bson:"access_token,omitempty"`
}

并在user/accounts即时通讯中尝试将此帐户结构嵌入到另一个结构中

type returnAccount struct {
    user.Account
    AccessToken string `json:"access_token,omitempty"`
}

用户包已正确导入，然后尝试嵌入，我已成功使用它

最终，我正在获取用户帐户并制作returnAccount功能图并从中返回，这是我的功能

func getAccounts(usr *user.AuthenticatedUser, id ...string) (accounts map[string]returnAccount) {
    accounts = make(map[string]returnAccount)
    if len(id) > 0 {
        for _, v := range id {
            for _, acnt := range usr.Accounts {
                if acnt.AccountId == v {
                    accounts[acnt.AccountId] = returnAccount{
                        Tp:       acnt.Tp,
                        AccountId:acnt.AccountId,
                    }
                }
            }
        }
        return
    }
    for _, v := range usr.Accounts {
        accounts[v.AccountId] = returnAccount{
            Tp:       v.Tp,
            AccountId:v.AccountId,
            Username: v.Username,

        }

    }
    return
}

但是此代码不会在这里编译是错误消息

# sgin/api/user/accounts
api/user/accounts/getaccounts.go:16: unknown returnAccount field 'Tp' in struct literal
api/user/accounts/getaccounts.go:17: unknown returnAccount field 'AccountId' in struct literal
api/user/accounts/getaccounts.go:26: unknown returnAccount field 'Tp' in struct literal
api/user/accounts/getaccounts.go:27: unknown returnAccount field 'AccountId' in struct literal
api/user/accounts/getaccounts.go:28: unknown returnAccount field 'Username' in struct literal

一切似乎都非常简单明了，我无法弄清楚为什么会出现此错误，并且我需要达到Account结构的所有成员都已导出

我需要此字段的原因是我想通过api发送访问令牌给客户端，而不是秘密，并且我想减少缩进级别
