phonegap(cordova) 自定义插件代码篇（一）----IAP 应用内支付

标签：

appstore 中审核中，如果你app内卖的东西是个虚拟的产品，那么你有可能被要求不能使用第三方支付工具，只能使用 IAP 应用内支付功能。

使用这个功能需要在apple 开发者后台签合同，设置银行账号，设置价格，这个就不讲了，本篇主要讲phonegap中整合IAP的代码

/**
 * 苹果应用内支付
 */

(function (cordova) {
    var define = cordova.define;

    define("cordova/plugin/applepay", function (require, exports, module) {
        var argscheck = require('cordova/argscheck'),
	    exec = require('cordova/exec');
        exports.pay = function (productID,quantity, successCB, failCB) {

            exec(successCB, failCB, "ApplePay", "pay", [productID,quantity]);

        }; 
    });
    cordova.addConstructor(function () {
        if (!window.plugins) {
            window.plugins = {};
        }
        console.log("将插件注入cordovaapplepay...");
        window.plugins.applepay = cordova.require("cordova/plugin/applepay");
        console.log("applepay注入结果：" + typeof (window.plugins.applepay));
    });
})(cordova);

}

最后服务端的验证，服务端我用的是 C# 

 public bool ApplePayNotifyVerify(ApplePayParam param)
        {
            //验证支付凭证
            // 初始化通信处理类

            try
            {
                //支付凭证不能被重复使用，检查支付凭证是否已经被计入流水账，如果被使用过，直接返回false, 未被使用过的才可以验证，并处理相关业务
                var payment = PaymentService.Instance.GetList(p => p.AppleReceipt == param.AppleReceipt).FirstOrDefault();
                if (payment == null)
                {

                    var config = AppService.Instance.GetThirdPartyConfig();
                    System.Net.Http.HttpClient httpClient = new System.Net.Http.HttpClient();
                    httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                    var receipt = "{\"receipt-data\":\"" + param.AppleReceipt + "\"}";
                    HttpContent content = new StringContent(receipt, Encoding.UTF8);
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                    HttpResponseMessage response = httpClient.PostAsync(new Uri(config.ApplePayVerify), content).Result;
                    string result = response.Content.ReadAsStringAsync().Result.Replace(Environment.NewLine, string.Empty).Replace("\n", string.Empty);
                    var entity= JObject.Parse(result);
                    //AppleVerifyEntity entity = JsonConvert.DeserializeObject<AppleVerifyEntity>(result);
                    if (entity.Value<int>("status") == 0)
                    {
                        //成功之后修改订单状态，记帐，加花
                        OrderPaySuccessParam payParam = new OrderPaySuccessParam();
                        //订单号
                        payParam.OrderNO = param.OrderNO;
                        //交易号
                        payParam.TradeNO = param.TradeNO;
                        //支付方式
                        payParam.PayMethod = PaymentMethodKind.Online;

                        //卖家收款账户
                        payParam.Account = config.ApplePayBankAccount;
                        //卖家收款账户银行
                        payParam.Bank = config.ApplePayBankName;
                        //买家账户
                        payParam.PayAccount = "";
                        //买家收款账户银行

                        //实际支付金额
                        var order = OrderService.Instance.GetList(o => o.OrderNO == param.OrderNO).FirstOrDefault();
                        //苹果支付没有返回支付金额，为了避免后期验证不通过，设置总金额为实际订单金额
                        payParam.TotalAmount = order.TotalAmount;
                        //支付时间
                        payParam.PayDate = DateTime.Now;
                        //支付工具类型
                        payParam.PayType = PayTypeKind.ApplePay;
                        //记录支付凭证到流水账
                        payParam.AppleReceipt = param.AppleReceipt;

                        OrderService.Instance.OrderPaySuccess(payParam);
                        return true;
                    }
                    else
