我想使用 way2sms 发送短信。我试过下面的代码

login.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication1
{
  public partial class Login : System.Web.UI.Page
  {
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void btnconnect_Click(object sender, EventArgs e)
    {
        Session["id"] = txtmobileno.Text;
        Session["pw"] = txtpw.Text;
        Response.Redirect("/send.aspx");
    }
  }
 }

            }
            catch (Exception)
            {
                lblErrormsg.Text = "Error Sending msg....check your connection...";
            }
        }
        else
        {
            lblErrormsg.Text = "Mob no or msg missing";
        }
    }

    protected void btnLogOut_Click(object sender, EventArgs e)
    {
        Session["id"] = null;
        Session["pw"] = null;
        Session["error"] = null;
        Server.Transfer("login.aspx");
    }

  }
}

但它不起作用。我必须对这段代码进行任何更改吗？ 请告诉我从桌面应用程序或web应用程序

最佳答案

我不知道 way2sms 但我找到的最简单的 SMS API 是 http://cp.bulksmsportal.co.za/sms_default.aspx
代码也很简单

public static void sendSMS(string Recepient, string Message)
{
    //Recepient is the cellno in string format
    StringBuilder sb = new StringBuilder();
    sb.Append("http://www.mymobileapi.com/api5/http5.aspx?");
    sb.Append("Type=sendparam");
    sb.Append("&username={yourusername}");//add your username here
    sb.Append("&password={yourpassword}");//add your password here
    sb.AppendFormat("&numto={0}", Recepient);
    string message = HttpUtility.UrlEncode(Message, ASCIIEncoding.ASCII);
    sb.AppendFormat("&data1={0}", message);

    try
    {
        ////Create the request and send data to the SMS Gateway Server by HTTP connection
        HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(sb.ToString());
        //Get response from the SMS Gateway Server and read the answer
        HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();
        System.IO.StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());
        string responseString = respStreamReader.ReadToEnd();
        respStreamReader.Close();
        myResp.Close();
    }
    catch (Exception ex)
    {

    }
}
