C# WebAPI完成iOS支付验证

C# WebAPI完成iOS支付验证

后端使用C# WebApi框架，用户支付完成后请求API地址对支付结果进行后端检验并完成相关数据的修改。

API 方法

// API Post 请求
public string Post(IOSplay iosplay)
{
   // 连接数据库
   SqlConnection sqlConnection = new SqlConnection(@"");
   try
   {
       // 入参校验
       if (iosplay.transactionReceipt != "" && iosplay.productid != "" && iosplay.userid != "")
       {
          // IOS支付检验参数
           string strJosn = string.Format("{{\"receipt-data\":\"{0}\",\"password\":\"\"}}", iosplay.transactionReceipt);
           // 请求iOS检验地址
           string fsjisa = CreatePostHttpResponse(strJosn);
           JObject obj = JObject.Parse(fsjisa);
           // 判断是否购买成功
           if (obj["status"].ToString() == "0")
           {
           	// 支付成功 进行数据库操作
               sqlConnection.Open();
                string sqlxz = "insert into iosplay()  values()";
               DataSet dataSetq = new DataSet();
               SqlDataAdapter sqlDataAdapterq = new SqlDataAdapter(sqlxz, sqlConnection);
               sqlDataAdapterq.Fill(dataSetq);
               sqlConnection.Close();
               return "success";        
           }
           else
           {
               // 支付验证失败，数据库最好也进行一下记录
               sqlConnection.Open();
               string sqlxz2 = "insert into iosplay()  values()";
               DataSet dataSetq2 = new DataSet();
               SqlDataAdapter sqlDataAdapterq2 = new SqlDataAdapter(sqlxz2, sqlConnection);
               sqlDataAdapterq2.Fill(dataSetq2);
               sqlConnection.Close();
               return "IOS订单验证失败";
           }
       }
       else
       {
          // 入参错误
           sqlConnection.Open();
           string sqlxz3 = "insert into iosplay(sdduihuan)  values(@duihshif)";
           DataSet dataSetq3 = new DataSet();
           SqlDataAdapter sqlDataAdapterq3 = new SqlDataAdapter(sqlxz3, sqlConnection);
           sqlDataAdapterq3.SelectCommand.Parameters.AddWithValue("@duihshif", "请求参数错误");
           sqlDataAdapterq3.Fill(dataSetq3);
           sqlConnection.Close();
           return "请求参数错误";
       }
   }
   catch (Exception ex)
   {
       // 处理异常
       sqlConnection.Open();
       string sqlxz4 = "insert into iosplay(sdduihuan)  values(@duihshif)";
       DataSet dataSetq4 = new DataSet();
       SqlDataAdapter sqlDataAdapterq4 = new SqlDataAdapter(sqlxz4, sqlConnection);
       sqlDataAdapterq4.SelectCommand.Parameters.AddWithValue("@duihshif", ex.ToString());
       sqlDataAdapterq4.Fill(dataSetq4);
       sqlConnection.Close();
       return "error"+ ex.ToString();
   }
   finally
   {
       sqlConnection.Close();
   }
}

CreatePostHttpResponse（请求IOS验证地址）

public string CreatePostHttpResponse(string datas, bool isSandbox = false)
{
    string url_buy = "https://buy.itunes.apple.com/verifyReceipt"; // 正式购买地址
    string url_sandbox = "https://sandbox.itunes.apple.com/verifyReceipt"; //  沙盒购买地址
    string url = isSandbox ? url_sandbox : url_buy;

    HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
    request.ProtocolVersion = HttpVersion.Version10;
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    byte[] data = Encoding.GetEncoding("UTF-8").GetBytes(datas.ToString());
    using (Stream stream = request.GetRequestStream())
    {
        stream.Write(data, 0, data.Length);
    }
    HttpWebResponse response = request.GetResponse() as HttpWebResponse;
    Stream responseStream = response.GetResponseStream();   //获取响应的字符串流
    StreamReader sr = new StreamReader(responseStream); //创建一个stream读取流
    var str = sr.ReadToEnd();
    sr.Close();
    responseStream.Close();
    return str.ToString();
}
