使用測(cè)試數(shù)據(jù)，我可以創(chuàng)建一個(gè)客戶并附加一種付款方式，但我的所有訂閱都處于這種狀態(tài)。這是我目前創(chuàng)建訂閱的代碼：// StripeCreateSubscription create a new subscription with fixed price for userfunc StripeCreateSubscription(w http.ResponseWriter, r *http.Request) {    if r.Method != "POST" {        SendResponse(w, utils.MakeError("you can only POST to the stripe create customer route"), http.StatusMethodNotAllowed)        return    }    // Decode the JSON payload    type requestPayload struct {        PaymentMethodID string `json:"paymentMethodId"`        PriceID         string `json:"priceId"`    }    var payload requestPayload    if err := json.NewDecoder(r.Body).Decode(&payload); err != nil {        sendSystemError(w, fmt.Errorf("decode request payload: %v", err))        return    }    // Get the user from the context of who made the request    uid := r.Context().Value("user_id").(int)    u := models.User{}    if err := u.FindByID(uid); err != nil {        sendSystemError(w, fmt.Errorf("find user by id: %v", err))        return    }    if u.StripeCustomerID == "" {        sendSystemError(w, errors.New("no customer for the user"))        return    }    // Attach the payment method to the customer    paymentParams := &stripe.PaymentMethodAttachParams{        Customer: stripe.String(u.StripeCustomerID),    }    pm, err := paymentmethod.Attach(        payload.PaymentMethodID,        paymentParams,    )    if err != nil {        sendSystemError(w, fmt.Errorf("attaching payment method failed: %v", err))    }    // Check if the user has any active subscriptions, and cancel the others if they're adding one.    listParams := &stripe.SubscriptionListParams{        Customer: u.StripeCustomerID,        Status:   "all",    }我需要做什么才能讓我的訂閱完成付款？
