我想在付款插件中显示退货页面（Controllers＆gt; HomeControllers.cs）

public void NetConnect()
        {
            try
            {

        HttpClient client = new HttpClient();
                var values = new List<KeyValuePair<string, string>>();
                values.Add(new KeyValuePair<string, string>("Merchant_ID", "1709022104222235"));
                values.Add(new KeyValuePair<string, string>("Order_NO", "1321"));
                values.Add(new KeyValuePair<string, string>("Order_Amount", "900.00"));
                //values.Add(new KeyValuePair<string, string>("Date", DateTime.Now.ToString("dd/MM/yyyy")));
                //values.Add(new KeyValuePair<string, string>("Time", DateTime.Now.ToString("HH:mm:ss")));
                values.Add(new KeyValuePair<string, string>("Date", "11/09/2017"));
                values.Add(new KeyValuePair<string, string>("Time", "21:00:00"));

                values.Add(new KeyValuePair<string, string>("CheckSum", checksum));
                values.Add(new KeyValuePair<string, string>("Transaction_Desc", "Shop From SM Motors"));



                var content = new FormUrlEncodedContent(values);

                var response = client.PostAsync("http://http://www.smmotors.org/NetConnect/NetConnect", content).Result;
                var responseString =  response.Content.ReadAsStringAsync();

                var responseString1 = client.GetStringAsync("http://103.25.136.125/KPALServer/NetConnect.aspx");


    }
            catch (Exception)
            {
                throw new Exception();
            }

        }

我将数据发布到特定网址＆amp;想要显示返回页面。

作为回报，上面的代码显示空白页面。请指导如何显示返回页面。

Answer 1

那么你可以尝试这个简短的代码，它不那么复杂，而且正是你想要实现的目标添加以下静态类

public static class Http
{
    public static string Post(string uri, NameValueCollection pairs)
    {
        byte[] response = null;
        using (WebClient client = new WebClient())
        {
            response = client.UploadValues(uri, pairs);
        }
        return System.Text.Encoding.UTF8.GetString(response);
    }
}

然后简单地说：

var response = Http.Post("http://103.25.136.125/KPALServer/NetConnect.aspx", new NameValueCollection() {
    { "Merchant_ID", "170900010400235" },
    { "Order_NO", "1321" },
    { "Order_Amount", "900.00" } //similarly include all your post parameters
});

  public void PostProcessPayment(PostProcessPaymentRequest postProcessPaymentRequest)
    {

    string orderNo = postProcessPaymentRequest.Order.Id.ToString();
    string amount = postProcessPaymentRequest.Order.OrderTotal.ToString("0.00", CultureInfo.InvariantCulture);
    string merchantId = _NetConnectPaymentSettings.CustomerId;  
    string date = DateTime.Now.ToString("dd/MM/yyyy");
    string time = DateTime.Now.ToString("HH:mm:ss");
    string urlNetConnect = _NetConnectPaymentSettings.PaymentPage;


    string checksum = Generate_MerchantRequest_Check_Sum("7C12B6AECC51A3F3189799098AB1981", merchantId, orderNo, amount, date, time);

    var client = new HttpClient();

    var values = new List<KeyValuePair<string, string>>();
    values.Add(new KeyValuePair<string, string>("Merchant_ID", merchantId));
    values.Add(new KeyValuePair<string, string>("Order_NO", orderNo));
    values.Add(new KeyValuePair<string, string>("Order_Amount", amount));

    values.Add(new KeyValuePair<string, string>("Date", date));
    values.Add(new KeyValuePair<string, string>("Time", time));

    values.Add(new KeyValuePair<string, string>("CheckSum", checksum));
    values.Add(new KeyValuePair<string, string>("Transaction_Desc", "Shop From SM Motors"));


    var content = new FormUrlEncodedContent(values);



    //HttpResponseMessage response = client.PostAsync("http://www.smmotors.org", content).Result;

HttpResponseMessage response = client.PostAsync(urlNetConnect, content).Result;

    if (response.IsSuccessStatusCode)
    {
        var responseString = response.Content.ReadAsStringAsync();


        HttpContext.Current.Response.Write(responseString.Result);
        HttpContext.Current.ApplicationInstance.CompleteRequest();
        HttpContext.Current.Response.End();
        _webHelper.IsPostBeingDone = true;

    }
    else
    {
        throw new NopException();
    }


       return;
}
