Unity自带IAP插件使用（googleplay）

https://blog.csdn.net/ar__ha/article/details/64439872

Unity Services里的Unity IAP对于IOS和GooglePlay的支付用这个插件就足够了。

Unity官方文档

1.集成插件

Window-Services（Ctrl+0）在Services面板Link你的工程，启用In-App Purchase，Import/Update一下，插件就在Assets/Plugins/UnityPurchasing下。

2.设置

以GooglePlay的设置为例

Window - Unity Iap - Android - Target Google Play ：选择GooglePlay，

Window - Unity Iap - Receipt Validation Obfuscator ：输入GooglePlay的PublicKey，

点击Obfuscate secrets后，在Assets/Plugins/UnityPurchasing/generated下会生产GooglePlayTangle自动生成的文件，不用管他。

但是要注意到他的宏定义

#if UNITY_ANDROID || UNITY_IPHONE || UNITY_STANDALONE_OSX || UNITY_TVOS

 

3.DEMO

插件的demo在Assets/Plugins/UnityPurchasing/scenes/IAP Demo 这个场景里

也可以直接看cs文件，Assets/Plugins/UnityPurchasing/script/IAPDemo.cs

主要用到的是UnityEngine.Purchasing.IStoreListener 这个接口

4.初始化

1.  
   //使用这个解析IAP成功后的receipt
2.  
   private UnityEngine.Purchasing.Security.CrossPlatformValidator validator;
3.  
    
4.  
    
5.  
   private void InitUnityPurchase() {
6.  
   var module = StandardPurchasingModule.Instance();
7.  
   var builder = ConfigurationBuilder.Instance (module);
8.  
    
9.  
   //添加计费点
10.  
    // UnityEngine.Purchasing.ProductType
11.  
    builder.AddProduct("item1", ProductType.Consumable, new IDs
12.  
    {
13.  
    {"苹果计费点", AppleAppStore.Name },
14.  
    {"谷歌计费点", GooglePlay.Name}
15.  
    }
16.  
    );
17.  
    #if !UNITY_EDITOR
18.  
    validator = new CrossPlatformValidator(GooglePlayTangle.Data(), AppleTangle.Data(), Application.bundleIdentifier);
19.  
    #endif
20.  
    UnityPurchasing.Initialize (this, builder);
21.  
    }

 

实现IStoreListener 接口初始化回调

 

成功：

1.  
   private IStoreController m_Controller;
2.  
    
3.  
    
4.  
   //UNITY IAP初始化成功
5.  
   public void OnInitialized (IStoreController controller, IExtensionProvider extensions) {
6.  
   m_Controller = controller;
7.  
    
8.  
   // On Apple platforms we need to handle deferred purchases caused by Apple's Ask to Buy feature.
9.  
   // On non-Apple platforms this will have no effect; OnDeferred will never be called.
10.  
    var m_AppleExtensions = extensions.GetExtension<IAppleExtensions> ();
11.  
    m_AppleExtensions.RegisterPurchaseDeferredListener(OnDeferred);
12.  
     
13.  
    var product = m_Controller.products.WithID("item1");
14.  
    //价格 (带货币单位的字符串)
15.  
    var priceString = product.metadata.localizedPriceString;
16.  
    //价格 （换算汇率后的价格）
17.  
    var price = product.metadata.localizedPrice;
18.  
    }

失败：

1.  
   //初始化失败（没有网络的情况下并不会调起，而是一直等到有网络连接再尝试初始化）
2.  
   public void OnInitializeFailed (InitializationFailureReason error) {
3.  
    
4.  
   Debug.Log("Billing failed to initialize!");
5.  
   switch (error) {
6.  
   case InitializationFailureReason.AppNotKnown:
7.  
   Debug.LogError("Is your App correctly uploaded on the relevant publisher console?");
8.  
   break;
9.  
   case InitializationFailureReason.PurchasingUnavailable:
10.  
    // Ask the user if billing is disabled in device settings.
11.  
    Debug.Log("Billing disabled!");
12.  
    break;
13.  
    case InitializationFailureReason.NoProductsAvailable:
14.  
    // Developer configuration error; check product metadata.
15.  
    Debug.Log("No products available for purchase!");
16.  
    break;
17.  
    }
18.  
    }

 

5.发起支付

1.  
   public void DoIapPurchase (Action<bool, string> callback) {
2.  
   if (m_Controller != null) {
3.  
   var product = m_Controller.products.WithID ("item1");
4.  
   if (product != null && product.availableToPurchase) {
5.  
   //调起支付
6.  
   m_Controller.InitiatePurchase(product);
7.  
   }
8.  
   else {
9.  
   callback (false, "no available product");
10.  
    }
11.  
    }
12.  
    else {
13.  
    callback ( false, "m_Controller is null");
14.  
    }
15.  
    }

 

实现IStoreListener支付回调

 

成功：

1.  
   public PurchaseProcessingResult ProcessPurchase (PurchaseEventArgs e) {
2.  
   try {
3.  
   var result = validator.Validate (e.purchasedProduct.receipt);
4.  
   Debug.Log ("Receipt is valid. Contents:");
5.  
   foreach (IPurchaseReceipt productReceipt in result) {
6.  
   Debug.Log(productReceipt.productID);
7.  
   Debug.Log(productReceipt.purchaseDate);
8.  
   Debug.Log(productReceipt.transactionID);
9.  
    
10.  
    AppleInAppPurchaseReceipt apple = productReceipt as AppleInAppPurchaseReceipt;
11.  
    if (null != apple) {
12.  
    Debug.Log(apple.originalTransactionIdentifier);
13.  
    Debug.Log(apple.subscriptionExpirationDate);
14.  
    Debug.Log(apple.cancellationDate);
15.  
    Debug.Log(apple.quantity);
16.  
     
17.  
     
18.  
    //如果有服务器，服务器用这个receipt去苹果验证。
19.  
    var receiptJson = JSONObject.Parse(e.purchasedProduct.receipt);
20.  
    var receipt = receiptJson.GetString("Payload");
21.  
    }
22.  
     
23.  
    GooglePlayReceipt google = productReceipt as GooglePlayReceipt;
24.  
    if (null != google) {
25.  
    Debug.Log(google.purchaseState);
26.  
    Debug.Log(google.purchaseToken);
27.  
    }
28.  
    }
29.  
    return PurchaseProcessingResult.Complete;
30.  
    } catch (IAPSecurityException) {
31.  
    Debug.Log("Invalid receipt, not unlocking content");
32.  
    return PurchaseProcessingResult.Complete;
33.  
    }
34.  
    return PurchaseProcessingResult.Complete;
35.  
    }

失败：

1.  
   public void OnPurchaseFailed(Product i, PurchaseFailureReason p) {
2.  
   Logger.Warning("purchase failed of reason : " + p.ToString());
3.  
   }

IOS deferred：

1.  
   /// <summary>
2.  
   /// iOS Specific.
3.  
   /// This is called as part of Apple's 'Ask to buy' functionality,
4.

11.  
    private void OnDeferred(Product item)
