///收到产品返回的信息
    func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
        guard response.products.count > 0 , let product = response.products.first(where: {$0.productIdentifier == self.currenProductId})else {
            self.faileCall(.noExist)
            return
        }
        //检测是否允许购买
        guard SKPaymentQueue.canMakePayments() else { faileCall(.noPermission); return }
        //生成购买对象
        let payment = SKPayment(product: product)
        //发起购买请求
        SKPaymentQueue.default().add(payment)
    }

response.products.count一直为0
