工行支付api查询asp.net C# 实现

工行的测试环境真是非常地烂,给的api查询居然是c++的,还写着dotnet的名字,这里我给出一个asp.net c#的实现

public class ICBC_API

{

static string apiUrl = "https://corporbank3.dccnet.com.cn/servlet/ICBCINBSEBusinessServlet";

static string cerPath = ConfigurationManager.AppSettings["CertPath"];

static string cerPwd = ConfigurationManager.AppSettings["CertPwd"];

public ICBC_API()

{

}

/// <summary>

/// 订单查询

/// </summary>

/// <param name="orderNum">订单号</param>

/// <param name="tradeDate">订单日期(yyyyMMdd)</param>

/// <param name="shopCode">商户代码</param>

/// <param name="shopAccount">商户帐号</param>

/// <returns></returns>

public static string B2C(string orderNum,string tradeDate,string shopCode,string shopAccount)

{

//gen post data

string postParams = "APIName=EAPI&APIVersion=001.001.002.001&MerReqData={0}";

StringBuilder sb = new StringBuilder();

sb.Append("<?xml version=\"1.0\" encoding=\"GBK\" standalone=\"no\" ?><ICBCAPI><in><orderNum>");

sb.Append(orderNum);

sb.Append("</orderNum><tranDate>");

sb.Append(tradeDate);

sb.Append("</tranDate><ShopCode>");

sb.Append(shopCode);

sb.Append("</ShopCode><ShopAccount>");

sb.Append(shopAccount);

sb.Append("</ShopAccount></in></ICBCAPI>");

string postData = string.Format(postParams, sb.ToString());

//验证证书,默认有效

ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate);

//配置请求参数

HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create(apiUrl);

wReq.ContentType = "application/x-www-form-urlencoded";

wReq.Method = "POST";

wReq.ClientCertificates.Add(new X509Certificate2(HttpContext.Current.Server.MapPath(cerPath), cerPwd));

ASCIIEncoding encoding = new ASCIIEncoding();

byte[] data = encoding.GetBytes(postData);

wReq.ContentLength = data.Length;

Stream reqStream = wReq.GetRequestStream();

reqStream.Write(data, 0, data.Length);

reqStream.Close();

//获取结果

WebResponse wResp = wReq.GetResponse();

Stream respStream = wResp.GetResponseStream();

string stringResp = string.Empty;

if (respStream != null)

{

using (StreamReader respReader = new StreamReader(respStream,Encoding.GetEncoding("GBK")))

{

stringResp = respReader.ReadToEnd();

}

respStream.Close();

}

return stringResp;

}

}
