"哎,又双叒叕充值失败了!"小王盯着手机屏幕上的"支付异常"提示,第N次放弃给游戏账号充值,作为资深游戏玩家,他经历过无数次因支付流程复杂、回调失败导致的充值体验灾难,直到某天,他发现某新游的充值系统快如闪电,原来——背后的开发者用了这套ASP充值方案!
(假装这里有张流程图:用户点击充值→跳转支付网关→完成支付→系统回调更新余额)
框架选择
✅ 推荐ASP.NET Core 9.0(传统ASP已过时,别再用!🚫)
dotnet new webapi -n RechargeSystem
支付网关注册
安全配置
services.AddHttpsRedirection(); // 强制HTTPS services.AddAuthentication(CertificateAuth) // 证书校验
[HttpPost("alipay/order")] public IActionResult CreateOrder([FromBody] RechargeRequest request) { var alipay = new AlipayTradePagePayModel { OutTradeNo = Guid.NewGuid().ToString(), // 唯一订单号 TotalAmount = request.Amount.ToString("F2"), Subject = "游戏币充值", ProductCode = "FAST_INSTANT_TRADE_PAY" }; var response = alipayClient.PageExecute(alipay, "GET"); return Redirect(response.Body); // 跳转支付宝收银台 }
[HttpPost("alipay/notify")] public async Task<IActionResult> Notify() { var stream = new StreamReader(Request.Body).ReadToEnd(); var params = AlipaySignVerify.Parse(stream); // 🔒 双重验证 if (!AlipaySignVerify.Check(params, alipayPublicKey)) return BadRequest("签名验证失败"); // 🎯 更新用户余额 var userId = params["passback_params"]; await _dbContext.UpdateBalance(userId, params["total_amount"]); return Content("success"); // 必须返回success字符串 }
// Vue组件示例 async function pay() { const res = await axios.post('/wechat/order', { amount: 100 }); WeixinJSBridge.invoke( 'getBrandWCPayRequest', { appId: res.data.appId, timeStamp: res.data.timeStamp, nonceStr: res.data.nonceStr, package: res.data.package, signType: 'MD5', paySign: res.data.paySign }, function(rsp) { if (rsp.err_msg === 'get_brand_wcpay_request:ok') { alert('充值成功!'); } } ); }
public WechatPayResponse CreateWechatOrder(decimal amount) { var package = $"prepay_id={wechatOrder.prepay_id}"; var paySign = SignHelper.GenerateMD5($"appId={AppId}&nonceStr={nonceStr}&package={package}..."); return new WechatPayResponse { appId = AppId, timeStamp = DateTimeOffset.Now.ToUnixTimeSeconds().ToString(), nonceStr = nonceStr, package = package, paySign = paySign }; }
大额交易监控
🔥 单笔超5万需上报央行,代码中自动检测:
if (amount > 50000) await _regulationService.ReportLargeTransaction(userId, amount);
防洗钱策略
🚨 禁止私人账户收款,强制对公账户:
[AttributeUsage(AttributeTargets.Class)] public class RequireEnterpriseAccountAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext context) { if (context.HttpContext.User.IsInRole("PersonalAccount")) context.Result = new ForbidResult(); } }
测试场景 | 预期结果 |
---|---|
充值100元(支付宝) | 余额+100,支付消息推送 |
微信支付取消后重试 | 订单未关闭时可继续支付 |
50000元大额充值 | 触发监管上报,30分钟后到账 |
容器化部署
FROM mcr.microsoft.com/dotnet/aspnet:9.0 COPY bin/Release/net9.0/publish/ App/ WORKDIR /App ENTRYPOINT ["dotnet", "RechargeSystem.dll"]
性能监控
📈 接入阿里云ARMS:
services.AddApplicationInsightsTelemetryWorkerService(config => { config.ConnectionString = "InstrumentationKey=xxx"; });
用户小王再次尝试充值时,发现:
✅ 3秒内完成支付跳转
✅ 微信/支付宝无缝切换
✅ 实时到账通知
✅ 50000元大额充值自动分账到公司账户
轮到你打造丝滑充值体验了!💪
