uni-app中C#配置支付宝信息
uni-app中C#配置支付宝信息
参考支付宝官方的demo配置的方法,亲测可行.
public object GetPayInfo(string _amount)//_amount:付款金额
{
string orderInfo = OrderInfo(_amount);
// 对订单做RSA 签名
string sign = RSAFromPkcs8.sign(orderInfo, Config.Private_key, Config.Input_charset); //支付宝提供的Config.cs
//仅需对sign做URL编码
sign = HttpUtility.UrlEncode(sign, Encoding.UTF8);
string payInfo = orderInfo + "&sign=\"" + sign + "\"&"
+ getSignType();
return payInfo;
}
public string OrderInfo(string price)
{
Dictionary<string, string> payinfo = new Dictionary<string, string>();
payinfo.Add("service", "\"mobile.securitypay.pay\"");
payinfo.Add("partner", "\"" + Config.Partner + "\"");
payinfo.Add("seller_id", "\"" + Config.SELLER + "\"");
payinfo.Add("out_trade_no", "\"" + DateTime.Now.ToString("yyyyMMddHHmmssfff")+ "\"");
payinfo.Add("subject", "\"****\"");
payinfo.Add("body", "\"*****\"");
payinfo.Add("total_fee", "\"" + price.ToString() + "\"");
payinfo.Add("notify_url", "\"***********"");
payinfo.Add("payment_type", "\"1\"");
payinfo.Add("_input_charset", "\"UTF-8\"");
payinfo.Add("it_b_pay", "\"30m\"");
return Core.CreateLinkString(payinfo);
}
public String getSignType()
{
return "sign_type=\"RSA\"";
}
HB中的方法
function topay(rate) {
if (w) {
return;
}
//检查是否请求订单中
w = plus.nativeUI.showWaiting();
mui.getJSON("http://************/api/Pay", {
_amount: rate
}, function(data) {
w.close();
w = null;
if (data) {
plus.payment.request(pays["alipay"], data, function(result) {
plus.nativeUI.alert("支付成功:感谢您的支持。", function() {
mui.back();
}, "****");
}, function(error) {
if (error.code == 62001) {
mui.toast("您放弃支付.");
mui.back();
} else {
plus.nativeUI.alert("支付失败", null, "请前往会员中心再次对该订单尝试支付,支付失败:" + error.code);
}
});
}
});
}

在uni-app中配置支付宝支付通常涉及服务器端(如使用C#)的配置以及客户端(uni-app)的集成。由于uni-app本身是跨平台的前端框架,它本身不直接处理支付配置,而是通过与后端服务器交互来完成支付流程。以下是如何在C#后端配置支付宝支付的代码示例。
1. 引入支付宝SDK
首先,你需要在C#项目中引入支付宝的SDK。你可以通过NuGet包管理器来安装支付宝的SDK。
Install-Package Alipay.AopSdk.Core
2. 配置支付宝参数
在C#项目中,你需要配置支付宝的相关信息,如App ID、私钥、公钥、支付宝网关等。这些信息通常存储在配置文件(如appsettings.json
)中。
{
"Alipay": {
"AppId": "your_app_id",
"PrivateKey": "your_private_key",
"AlipayPublicKey": "your_alipay_public_key",
"GatewayUrl": "https://openapi.alipay.com/gateway.do",
"Format": "json",
"Charset": "UTF-8",
"SignType": "RSA2"
}
}
3. 创建支付请求
接下来,你需要创建一个方法来处理支付请求。以下是一个创建支付订单的示例代码:
using Alipay.AopSdk.Core;
using Alipay.AopSdk.Core.Domain;
using Alipay.AopSdk.Core.Request;
using Microsoft.Extensions.Configuration;
using System;
public class AlipayService
{
private readonly IConfiguration _configuration;
public AlipayService(IConfiguration configuration)
{
_configuration = configuration;
}
public string CreateOrder(decimal totalAmount, string subject, string outTradeNo)
{
var alipayConfig = new DefaultAopClientConfig
{
AppId = _configuration["Alipay:AppId"],
PrivateKey = _configuration["Alipay:PrivateKey"],
ServerUrl = _configuration["Alipay:GatewayUrl"],
Format = _configuration["Alipay:Format"],
Charset = _configuration["Alipay:Charset"],
SignType = _configuration["Alipay:SignType"],
AlipayPublicKey = _configuration["Alipay:AlipayPublicKey"]
};
var client = new DefaultAopClient(alipayConfig);
var model = new AlipayTradePagePayModel
{
OutTradeNo = outTradeNo,
TotalAmount = totalAmount.ToString("F2"),
Subject = subject,
ProductCode = "FAST_INSTANT_TRADE_PAY"
};
var request = new AlipayTradePagePayRequest
{
BizModel = model,
NotifyUrl = "your_notify_url" // 异步回调地址
};
var result = client.PageExecute(request, null);
return result.Body; // 返回支付宝支付表单的HTML代码
}
}
4. 在uni-app中调用
在uni-app中,你可以通过HTTP请求调用上述C#后端服务来获取支付宝的支付表单HTML,并将其嵌入到页面中。
uni.request({
url: 'https://your-backend-server/api/alipay/createOrder',
method: 'POST',
data: {
totalAmount: 100,
subject: 'Test Order',
outTradeNo: '202304010001'
},
success: (res) => {
const html = res.data;
// 将html嵌入到页面中
const div = document.createElement('div');
div.innerHTML = html;
document.body.appendChild(div);
}
});
以上代码展示了如何在C#后端配置支付宝支付,并在uni-app中调用该服务。
