Json 如何从条带订阅响应对象中正确获取 struct 项

我正在try 从订阅的条带响应对象的 struct 中获取一些数据.这里是到响应对象stribe subscription object的 struct 的链接

这就是我所拥有的和正在努力做的事情

type SubscriptionDetails struct {
    CustomerId             string  `json:"customer_id"`
    SubscritpionId         string  `json:"subscritpion_id"`
    StartAt                time.Time  `json:"start_at"`
    EndAt                  time.Time  `json:"end_at"`
    Interval               string  `json:"interval"`
    Plan                   string  `json:"plan"`
    PlanId                 string  `json:"plan_id"`
    SeatCount              uint8  `json:"seat_count"`
    PricePerSeat           float64  `json:"price_per_seat"`
}



func CreateStripeSubscription(CustomerId string, planId string) (*SubscriptionDetails, error) {

    stripe.Key = StripeKey

    params := &stripe.SubscriptionParams{
    Customer: stripe.String(CustomerId),
    Items: []*stripe.SubscriptionItemsParams{
        &stripe.SubscriptionItemsParams{
        Price: stripe.String(planId),
        },
    },
    }
    result, err := sub.New(params)

    if err != nil {
        return nil, err
    }

    data := &SubscriptionDetails{}

    data.CustomerId           = result.Customer
    data.SubscritpionId       =  result.ID
    data.StartAt              =  result.CurrentPeriodStart
    data.EndAt                =  result.CurrentPeriodEnd
    data.Interval             =  result.Items.Data.Price.Recurring.Interval
    data.Plan                 =  result.Items.Data.Price.Nickname
    data.SeatCount            =  result.Items.Data.Quantity
    data.PricePerSeat         =  result.Items.Data.Price.UnitAmount


    return data, nil    
}

有一些项目很容易直接获得，比如我用result.ID轻松获得了ID字段，没有投诉，但对于其他项目，这里是我收到的错误消息

cannot use result.CurrentPeriodStart (type int64) as type time.Time in assignment
...
cannot use result.Customer (type *stripe.Customer) as type string in assignment
...
result.Items.Data.price undefined (type []*stripe.SubscriptionItem has no field or method price)

那么我如何获得data.CustomerId和data.PricePerSeat的数据呢？

最新情况:

以下是来自条带的订阅对象的 struct
