Question

我正在为我们的应用程序编写一个SMS函数。没有错误，但它不符合我的期望。使用数据集我得到多个手机号码，然后我需要将消息传递给所有这些手机号码。

1.使用Response.Redirect仅发送1条消息而其他消息未发送。（在发送第1条消息后，它将转到该页面）

下面的部分编码

DataSet DistDs = _distsms.GetAllDistributionList(UnitId, isShot, gameId, animalTypeId);
if(DistDs.Tables[0].Rows.Count > 0)
{   
    ContactNo = Convert.ToInt32(DistDs.Tables[0].Rows[0]["ContactNumber"]);
    foreach (DataRow row in DistDs.Tables[0].Rows)
    {
        if (row["ContactNumber"].ToString() != "")
        {
            try
            {
                Response.Redirect("http://sms.gatewaysite.com/api/mt?msisdn=" + row["ContactNumber"].ToString() +
                                  "&body=" + msgOut + "&sender=" + shortcode +
                                  "&key=ertyertyer&product_id=4563456&operator=" + oppp + "&country=aaaaa");
            }
            catch(Exception ee)
            {
                string a = ee.Message;
                //continue;
            }
        }
    }
}

Answer 1

Response.Redirect就是这样 - 它会重定向整个响应。

对于您要执行的操作，请使用HttpWebRequest

Answer 2

将数据发送到远程服务器是不好的方法。尝试使用Web服务调用或Web Api调用。您可以在哪里以JSON格式发送数据。 AFIK您要结束响应流。

或者您可以通过HTTP WebRequest

调用WebRequest

来自MSDN

WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx ");
            // Set the Method property of the request to POST.
            request.Method = "POST";
            // Create POST data and convert it to a byte array.
            string postData = "This is a test that posts this string to a Web server.";
            byte[] byteArray = Encoding.UTF8.GetBytes (postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/x-www-form-urlencoded";
            // Set the ContentLength property of the WebRequest.
            request.ContentLength = byteArray.Length;
            // Get the request stream.
            Stream dataStream = request.GetRequestStream ();
            // Write the data to the request stream.
            dataStream.Write (byteArray, 0, byteArray.Length);
            // Close the Stream object.
            dataStream.Close ();
            // Get the response.
            WebResponse response = request.GetResponse ();
            // Display the status.
            Console.WriteLine (((HttpWebResponse)response).StatusDescription);
            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream ();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader (dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd ();
            // Display the content.
            Console.WriteLine (responseFromServer);
            // Clean up the streams.
            reader.Close ();
            dataStream.Close ();
            response.Close ();

Response.Redirect仅发送1条消息
