google 内购记录

1.GooglePlay内购服务器验单配置 （新版本好像不需要API 配置关联，好像不需要了）

详细配置url: https://blog.csdn.net/wuyutaoktm/article/details/122450878

2. 用golang代码实现，主要是验证订单和发币,PAY_JSON 是上一个步骤申请的

func verifyAndConsumePurchase(info *PurchaseInfo) (bool, error, int8) {
	ctx := context.Background()
	rawByte, _ := json.Marshal(info)

	googlePayLog := &handler.GooglePayLog{
		UserID:            info.UserId,
		Raw:               string(rawByte),
		RespRaw:           "",
		PurchaseTokenMD5:  "",
		CheckStatus:       -1,
		ConsumptionStatus: -1,
		GoldStatus:        -1,
		RechargeID:        0,
		MsgErr:            "",
	}

	// 使用服务账号创建凭证
	conf, err := google.JWTConfigFromJSON([]byte(PAY_JSON), androidpublisher.AndroidpublisherScope)
	if err != nil {
		googlePayLog.MsgErr = "1:" + err.Error()
		db_common.ApplyInsertGooglePayLog(googlePayLog)
		zlog.F().Errorf("user_id:%d,producd_id:%s,%v", info.UserId, info.ProductID, googlePayLog.MsgErr)
		return false, err, 0
	}

	// 使用凭证创建Google Play Developer服务
	service, err := androidpublisher.NewService(ctx, option.WithTokenSource(conf.TokenSource(ctx)))
	if err != nil {
		googlePayLog.MsgErr = "2:" + err.Error()
		db_common.ApplyInsertGooglePayLog(googlePayLog)
		zlog.F().Errorf("user_id:%d,producd_id:%s,%v", info.UserId, info.ProductID, googlePayLog.MsgErr)
		return false, err, 0
	}

	// 调用API验证购买
	call := service.Purchases.Products.Get(info.PackageName, info.ProductID, info.PurchaseToken)
	response, err := call.Do()
	if err != nil {
		googlePayLog.MsgErr = "3:" + err.Error()
		db_common.ApplyInsertGooglePayLog(googlePayLog)
		zlog.F().Errorf("user_id:%d,producd_id:%s,%v", info.UserId, info.ProductID, googlePayLog.MsgErr)
		return false, err, 1
	}
	str, _ := json.Marshal(response)
	zlog.F().Infof("userId:%d,productId:%d,response: %+v", info.UserId, info.ProductID, str)
	//0：表示交易已成功，并且商品未被消费。
	//1：表示交易被取消。
	//2：可能表示交易被拒绝，或某些其他的错误状态。
	// 验证购买状态：0表示购买成功
	if response.PurchaseState != 0 {
		zlog.F().Errorf("user_id:%d,producd_id:%s,PurchaseState:%d", info.UserId, info.ProductID, response.PurchaseState)
		googlePayLog.CheckStatus = int8(response.PurchaseState)
		googlePayLog.PurchaseTokenMD5 = utils.Md5(response.PurchaseToken)
		db_common.ApplyInsertGooglePayLog(googlePayLog)

		return false, nil, 0
	}

	// 调用API确认消费（消耗商品）
	//consumeCall := service.Purchases.Products.Acknowledge(info.PackageName, info.ProductID, info.PurchaseToken, &androidpublisher.ProductPurchasesAcknowledgeRequest{})
	consumeCall := service.Purchases.Products.Consume(info.PackageName, info.ProductID, info.PurchaseToken)
	if err := consumeCall.Do(); err != nil {
		googlePayLog.CheckStatus = int8(response.PurchaseState)
		googlePayLog.PurchaseTokenMD5 = utils.Md5(response.PurchaseToken)
		googlePayLog.ConsumptionStatus = 0 // 0表示消费失败
		googlePayLog.MsgErr = "4:" + err.Error()
		db_common.ApplyInsertGooglePayLog(googlePayLog)
		zlog.F().Errorf("user_id:%d,producd_id:%s,%v", info.UserId, info.ProductID, googlePayLog.MsgErr)

		return false, err, 1
	}
	// 加币操作
	if err = dealMysql(info, googlePayLog); err != nil {
		googlePayLog.CheckStatus = int8(response.PurchaseState)
		googlePayLog.PurchaseTokenMD5 = utils.Md5(response.PurchaseToken)
		googlePayLog.ConsumptionStatus = 1 // 1表示消费失败
		googlePayLog.GoldStatus = 0        // 0 加币失败
		googlePayLog.MsgErr = "5:" + err.Error()
		db_common.ApplyInsertGooglePayLog(googlePayLog)
		zlog.F().Errorf("user_id:%d,producd_id:%s,%v", info.UserId, info.ProductID, googlePayLog.MsgErr)
		return false, err, 1
	} else {
		// success
		googlePayLog.CheckStatus = int8(response.PurchaseState)
		googlePayLog.PurchaseTokenMD5 = utils.Md5(response.PurchaseToken)
		googlePayLog.ConsumptionStatus = 1 // 1表示消费失败
		googlePayLog.GoldStatus = 1        // 0 加币失败
		db_common.ApplyInsertGooglePayLog(googlePayLog)
	}

	return true, nil, 0
}

3. 注意丢单情况,改成客户端主动查询丢单

丢单因为主要是因为支付操作都是在客户端完成的，非常容易受到网络等因素的影响，造成互相通信失败。比如：用户确认支付后，把请求提交给google play,可能因为网络不好造成，客户端没有接收到支付成功能消息（但有可能已经支付成功了，只是没收到支付结果而已）；还有客户端把支付结果通知给服务器时，也有可能因丢包等问题造成通知失败。

4. 官网服务端api

api接口，get 和 确认消耗consume
