当我在Google Store中上传Unity产品时，购买产品不起作用

Question

我正在尝试在我的项目中出售物品。但谷歌购买不起作用。在“文本框”中，它说“正在购买”，但那样卡住了，用户无法购买这些物品。

public class StoreMenu : MonoBehaviour, IStoreListener
{        
    private static StoreMenu Instance { set;get; }
    IStoreController controller;
    public TextMeshProUGUI Gold_Text;      
    public string[] product; // I wrote my products in unity side
    [SerializeField] 
    Text StatusInfo;
    int GoldNumber;

    private void Start()
    {
        IAPStart();
    }

    private void Awake()
    {
        Instance = this;
    }    

//Build product and IAPPurchasing
private void IAPStart()
{
    var module = StandardPurchasingModule.Instance();
    ConfigurationBuilder builder = ConfigurationBuilder.Instance(module);

    //Adding products
    foreach (string item in product)
    {
        builder.AddProduct(item, ProductType.Consumable);
    }
    UnityPurchasing.Initialize(this, builder);
}

//Start
public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
{
    this.controller = controller;
}

// When cannot get started
public void OnInitializeFailed(InitializationFailureReason error)
{
    //OnInitialize Error
    StatusInfo.text = ("Error: " + error.ToString());
}

//Purchase failed
public void OnPurchaseFailed(Product i, PurchaseFailureReason p)
{
    //WHEN FACE WITH PURCHASE ERROR 
    StatusInfo.text = ("Error: " + p.ToString());
}

//Purchase result
public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs e)
{
    GoldNumber = PlayerPrefs.GetInt("Save"); // Getting Golds from save data
    //PURCHASE SETTINGS
    //Does it check any product name
    if (string.Equals(e.purchasedProduct.definition.id, product[0], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 30);
        StatusInfo.text = "30 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else if (string.Equals(e.purchasedProduct.definition.id, product[1], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 50);
        StatusInfo.text = "50 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else if (string.Equals(e.purchasedProduct.definition.id, product[2], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 100);
        StatusInfo.text = "100 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else if (string.Equals(e.purchasedProduct.definition.id, product[3], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 200);
        StatusInfo.text = "200 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else if (string.Equals(e.purchasedProduct.definition.id, product[4], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 500);
        StatusInfo.text = "500 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else if (string.Equals(e.purchasedProduct.definition.id, product[5], System.StringComparison.Ordinal))
    {
        PlayerPrefs.SetInt("Save", GoldNumber + 1000);
        StatusInfo.text = "1000 Gold Purchase Completed";
        return PurchaseProcessingResult.Complete;
    }

    else
    {
        StatusInfo.text = "Waiting For Purchasing...";
        return PurchaseProcessingResult.Pending;
    }

}

它卡在了这里。在Texbox中，它表示“正在购买”，但没有任何反应。我认为由于此代码“ controller.InitiatePurchase（proc）”而被卡住了。但是我不知道为什么会这样。当项目统一运行时，所有按钮和购买代码都可以正常工作，我可以购买产品。但是在手机上什么也买不到。

//Using here for getting value from buttons. 
public void IAPButton(string id)
{
    //DOES IT availableToPurchase?s
    Product proc = controller.products.WithID(id);
    if (proc != null && proc.availableToPurchase)
    {
        StatusInfo.text = "Buying";
        //It stucks over here.
        controller.InitiatePurchase(proc);
    }
    else
    {
        StatusInfo.text = "Problem";
    }
}
