uni-app微信支付踩得坑总结,以及orderInfo格式

官方没有给出orderInfo的格式,所以不得不在官方示例hello_uni_app中截取(用HBuilderX新建示例工程)

微信支付订单:

支付宝订单:

网上搜到的比较重要的几篇参考文章:

 uniapp 开发踩坑记录

@将心比心 

https://www.cnblogs.com/ailingfei/p/10620316.html

微信APP支付官方文档-统一下单:

https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=9_1

@将心比心同学踩坑时提醒的一条关键信息就是,app支付返回的sign是30位!30位!30位! 所以你在做验证计算后还得截取前30位给坑爹的uniapp才能用!

1.要注意返回的参数大小写要严格对应,至少你在调参数时候要注意大小写不然调不到

2.timestamp是int型,不是string

我的服务端下单处理回调的代码部分如下:

var appId = order_result.appid;
var timeStamp = TenPayV3Util.GetTimestamp();
var nonce_str = order_result.nonce_str;
switch (paymentChannel)
{
	case PaymentChannel.小程序:
	case PaymentChannel.公众号:
		{
			var package = $"prepay_id={order_result.prepay_id}";
			var jobj = new JObject
			{
				{"appId", appId},
				{"timeStamp", int.Parse(timeStamp)},
				{"nonceStr", nonce_str},
				{"package", package},
				{"signType", "MD5"},
				{"paySign", TenPayV3.GetJsPaySign(appId, timeStamp, nonce_str, package, api_key)},
			};
			return jobj;
		}
	case PaymentChannel.开放平台:
		{
			var package = "Sign=WXPay";
			var partnerid = order_result.mch_id;
			var prepay_id = order_result.prepay_id;
			var paySign = TenPayV3.GetJsPaySign(appId, timeStamp, nonce_str, package, api_key);
			var sign = paySign.Substring(0, 30);
			var jobj = new JObject
			{
				{"appid", appId},
				{"timestamp", int.Parse(timeStamp)},
				{"noncestr", nonce_str},
				{"package", package},
				{"partnerid", partnerid},
				{"prepayid", prepay_id},
				{"sign", sign},
			};
			return jobj;
		}
	default:
		throw new Exception($"不支持的支付渠道:{paymentChannel}");
}

看到没,小程序公众号用的是一套,区别就在于有没有appId不过用一套无所谓,app支付的回调参数全部小写,不用驼峰式

然后要注意的是app支付成功后,微信发送的支付回调api要写成异步

为什么异步不能用void呢?坑在这里:

Asp.Net Core 轻松学-经常使用异步的你,可能需要看看这个文章
