C#代码如下
public class RequestInfo
{
/// <summary>
/// 商户秘钥
/// </summary>
public string paykey { get; set; }
/// <summary>
/// 请求地址
/// </summary>
public string req_uri { get; set; }
/// <summary>
/// 商户订单号
/// </summary>
public string out_trade_no { get; set; }
/// <summary>
/// 商品描述
/// </summary>
public string body { get; set; }
/// <summary>
/// 总金额
/// </summary>
public int total_fee { get; set; }
/// <summary>
/// 订单生成时间
/// </summary>
public string time_start { get; set; }
/// <summary>
/// 商户号
/// </summary>
public string mch_id { get; set; }
/// <summary>
/// 通知回调地址
/// </summary>
public string notify_url { get; set; }
/// <summary>
/// 签名方式
/// </summary>
public string sign_type { get; set; }
}
2.发起请求
public void SendPay(RequestInfo resInfo)
{
var dic = new Dictionary<string, string>
{
{"id",resInfo.mch_id},//个人支付Id
{"pay_id", resInfo.out_trade_no},//唯一标识，可以是用户ID,用户名,session_id(),订单ID,ip 付款后返回
{"type","1"},//1支付宝支付 3微信支付 2QQ钱包
{"price",price.ToString()},//总金额
{"notify_url",resInfo.notify_url},//通知回调地址，商户需改为自己的，且保证外网能POST发送数据请求成功.
{"return_url",""},//跳转地址
{"page","4"}
};
var query = GetOtherSignString(dic, resInfo.paykey);
Encoding en = Encoding.GetEncoding("UTF-8");
HttpWebResponse response = CreatePostHttpResponse(resInfo.req_uri, query, en);
Stream stream = response.GetResponseStream(); //获取响应的字符串流
StreamReader sr = new StreamReader(stream); //创建一个stream读取流
string html = sr.ReadToEnd(); //从头读到尾，放到字符串html
JavaScriptSerializer serializer = new JavaScriptSerializer();
Dictionary<string, object> json = (Dictionary<string, object>)serializer.DeserializeObject(html);
string status = "";
string code_url = "";
string code_img_url = "";
logger.Error(json);
foreach (var item in json)
{
if (item.Key == "status")
{
status = item.Value.ToString();
}
if (item.Key == "qrcode")
{
code_img_url = item.Value.ToString();
}
if (item.Key == "qr")
{
code_url = item.Value.ToString();
}
}
//发起支付
if (status != "" && status =="0")
{
imgCpdehUrl = code_img_url;
errmsg = "码支付本地订单(" + HttpUtility.HtmlEncode(tradeno) + ")处理成功.";
logger.Error(errmsg);
}
else
{
errmsg = "JSAPI码支付发起支付(" + HttpUtility.HtmlEncode(tradeno) + ")发生错误.";
logger.Error(errmsg);
return Content("<span style=‘color:#FF0000;font-size:20px‘>" + "抱歉，支付订单处理失败" + "</span><p>" + errmsg + "</p>");
}
}
3.扩展方法：处理请求参数
public static string GetOtherSignString(Dictionary<string, string> dic, string key)
{
var newDic = dic.Where(p => p.Key != "sign").OrderBy(p => p.Key);
string sign = "";
string urls = "";
foreach (var item in newDic)
{
if (item.Value == "" || item.Key == "sign") continue;//跳过不需要的参数名
//追加&拼接URL
if (sign != "")
{
sign += "&";
urls += "&";
}
sign += item.Key + "=" + item.Value;
urls += item.Key + "=" + HttpUtility.UrlEncode(item.Value);
}
sign = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(sign += key, "MD5");//md5加密
return urls + "&sign=" + sign;
}
4.通知回调处理
private static bool doNotifyProcess_shpayAliMA(string appid, string orderid, string srContent, out string resultValue, StringBuilder errorMsgs)
{
resultValue = "";
string _msg;
var str = srContent.Split(‘&‘);//分割回调字符串
string status = "";
string out_trade_no = "";
string price = "";
foreach (var item in str)
{
if (item.IndexOf("status") > -1)
{
status = item.Split(‘=‘)[1];//订单状态
}
if (item.IndexOf("pay_id") > -1)
{
out_trade_no = item.Split(‘=‘)[1];//订单号
}
if (item.IndexOf("money") > -1)
{
price = item.Split(‘=‘)[1];//价格
}
}
if (status != "" && Convert.ToInt32(status) == 0)
{
// 充值支付核心处理（回调信息写入 + 充值处理）
if (ServiceHelper.WriteAndFillOrderPay_ShAliMA(out_trade_no,decimal.Parse(price), "Post", out _msg))
{
// 商户成功接收到支付结果通知之后，返回http包体数据为SUCCESS。若返回数据非SUCCESS，则视为失败
resultValue = _SH_SUCCESS;
errorMsgs.Append("[MA成功](" + out_trade_no + ")" + resultValue);
return true;
}
else
{
// 回写订单发货失败
resultValue = _SH_ERROR;
errorMsgs.Append("[MA支付失败](" + out_trade_no + ")" + resultValue + _msg);
}
}
else
{
// 签名和数据解析失败
resultValue = _SH_ERROR;
errorMsgs.Append("[MA成功](" + out_trade_no + ")");
}
return false;
}
