通过nuget首先引用AopSdk.dll 包
下面写的是 Asp.Net MVC 下相关的支付接口
APP支付
配置客户端相关的参数，配置成自己的代码就可以了
private string APPID =
string.Empty;
private string APP_PRIVATE_KEY =
string.Empty;
private string ALIPAY_PUBLIC_KEY =
string.Empty;
private string CHARSET =
string.Empty; IAopClient client;
在支付接口构造函数中初始化Client信息
client =
new DefaultAopClient(
"https://openapi.alipay.com/gateway.do", APPID, APP_PRIVATE_KEY,
"json",
"1.0",
"RSA2", ALIPAY_PUBLIC_KEY, CHARSET,
false);
APP发起支付请求
/// <summary>
/// App发起支付请求
/// </summary>
/// <param name="tradeno">外部订单号，商户网站订单系统中唯一的订单号</param>
/// <param name="subject">订单名称</param>
/// <param name="totalAmout">付款金额</param>
/// <param name="itemBody">商品描述</param>
[HttpPost]
public JObject AppPayRequest(
string tradeno,
string subject,
string totalAmout,
string itemBody)
{
AlipayTradeAppPayRequest request =
new AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
AlipayTradeAppPayModel model =
new AlipayTradeAppPayModel();
model.Body =
itemBody;
model.Subject =
subject;
model.TotalAmount =
totalAmout;
model.ProductCode =
"quick_msecurity_pay";
model.OutTradeNo =
"20170216test01";
model.TimeoutExpress =
"30m";
request.SetBizModel(model);
request.SetNotifyUrl("https://xxxxxx/callback");
//这里和普通的接口调用不同，使用的是sdkExecute
AlipayTradeAppPayResponse response =
client.SdkExecute(request);
//HttpUtility.HtmlEncode是为了输出到页面时防止被浏览器将关键参数html转义，实际打印到日志以及http传输不会有这个问题
return JObject.Parse(HttpUtility.HtmlEncode(response.Body));
//页面输出的response.Body就是orderString 可以直接给客户端请求，无需再做处理。
}
Web支付调用
/// <summary>
///Web发起支付请求
/// </summary>
/// <param name="tradeno">外部订单号，商户网站订单系统中唯一的订单号</param>
/// <param name="subject">订单名称</param>
/// <param name="totalAmout">付款金额</param>
/// <param name="itemBody">商品描述</param>
[HttpPost]
public JObject WebPayRequest(
string tradeno,
string subject,
string totalAmout,
string itemBody)
{

new AlipayTradePayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
AlipayTradePayModel model =
new AlipayTradePayModel();
model.Body =
itemBody;
model.Subject =

model.TimeoutExpress =

request.SetBizModel(model);
request.SetNotifyUrl("https://xxxxxx/callback");
AlipayTradePayResponse response =
client.pageExecute(request); //返回表单信息，js submit
return JObject.Parse(HttpUtility.HtmlEncode(response.Body));
}
支付回调地址
/// <summary>
/// 异步POST回调
/// </summary>
/// <returns></returns>
public async Task<JObject>
NotifyPostAsync()
{
int i =
0;
IDictionary<
string,
string> sArray =
new Dictionary<
string,
string>
();
NameValueCollection coll;
coll =
await Request.Content.ReadAsFormDataAsync();
String[] requestItem =
coll.AllKeys;
for (i =
0; i < requestItem.Length; i++
)
{
sArray.Add(requestItem[i], coll.Get(requestItem[i]));
}
//1、获取交易号 在去支付宝校验知否存在该交易号 以及该交易号的支付状态
//2、验证是否是 我们自己商户 回调的订单信息
//3、验证知否金额是否是订单金额
//4、业务通知成功 要告知支付宝 不要继续发动通知回调 ，如果业务处理有异常 记录订单日志
//5、最后返回相关信息
return null;
}

}
ASP.NET Core 下面的支付，还是使用此SDK, 把DefaultAopClient 封装配置下Options 扩展到 IServiceCollection 方法注册服务即可，后期有时间补上这块的代码
