现在越来越多的游戏需要全球化运营.其中支付这块,最重要的就是IOS和Google Play是必须要支持的.

一般要实现的需求如下:

• 支持Google Play和IOS道具支付
• 根据本地货币转换汇率
• 支持游戏内订阅服务
• 内购重置功能

下面我来用U3D内置IAP逐条实现上述功能.

• 支持Google Play和IOS道具支付
  基础功能

    /**
     *  Description: 根据ID购买商品
     *  productID: 商品ID
     */
    public void BuyProductID(string productID)
    {
        if (m_PurchaseInProgress)
        {
            Debug.Log("Please wait, purchase in progress");
            return;
        }

        if (m_Controller == null)
        {
            Debug.LogError("Purchasing is not initialized");
            return;
        }

        if (m_Controller.products.WithID(productID) == null)
        {
            Debug.LogError("No product has id " + productID);
            return;
        }

        // For platforms needing Login, games utilizing a connected backend
        // game server may wish to login.
        // Standalone games may not need to login.
        if (m_IsLoggedIn == false)
        {
            Debug.LogWarning("Purchase notifications will not be forwarded server-to-server. Login incomplete.");
        }
        // Don't need to draw our UI whilst a purchase is in progress.
        // This is not a requirement for IAP Applications but makes the demo
        // scene tidier whilst the fake purchase dialog is showing.
        m_PurchaseInProgress = true;

        //Sample code how to add accountId in developerPayload to pass it to getBuyIntentExtraParams
        //Dictionary<string, string> payload_dictionary = new Dictionary<string, string>();
        //payload_dictionary["accountId"] = "Faked account id";
        //payload_dictionary["developerPayload"] = "Faked developer payload";
        //m_Controller.InitiatePurchase(m_Controller.products.WithID(productID), MiniJson.JsonEncode(payload_dictionary));
        m_Controller.InitiatePurchase(m_Controller.products.WithID(productID), "developerPayload");

购买时直接调用即可

 IAPManager.THIS.BuyProductID("test.pay4");

• 根据本地货币转换汇率

    /**
     *  Description: 获取商品信息
     *  key:商品id
     */
    public Product GetProduct(string key)
    {
        if (m_Controller == null)
        {
            Debug.LogError("Purchasing is not initialized");
            return null;
        }
        if (productDic == null)
        {
            productDic = new Dictionary<string, Product>();
            var products = m_Controller.products.all;
            foreach (var product in products)
            {
                productDic[product.definition.id] = product;
            }
        }
        return productDic[key];
    }

其中Product.metadata.localizedPriceString 就是本地货币单位.

• 支持游戏内订阅服务

订阅商品与一般商品购买上没有区别，正常购买就好了。
注意要设置好商品类型,开发者账号后台建立订阅型商品。
订阅型商品分两种，自动续订和非自动续订的，一般都是用自动续订(You know why!)。
促销，如1个月的订阅期，可以设置3天的免费试用期，用户购买后，免费期退订，是不收费的。但是如果过了试用期，或者忘记退订了,嘿嘿~

• 内购重置功能

    /**
     *  Description: 恢复购买
     */
    public void RestoreButtonClick()
    {
        if (m_IsGooglePlayStoreSelected)
        {
            m_GooglePlayStoreExtensions.RestoreTransactions(OnTransactionsRestored);
        }
        else
        {
            m_AppleExtensions.RestoreTransactions(OnTransactionsRestored);
        }
    }

非消耗品的恢复.
