通过ASP.NET C#发送HTTP请求

Question

我试图通过C#发送HTTP Get请求.但它似乎不起作用.这是我的工作.而且我想从你那里获得使其运作所需的更正!

            String Mobile = txt_phone.Text;
            String Message = "You have registered successfuly.";
            Uri targetUri = new Uri("http://sms-om.com/smspro/sendsms.php?user=HatemSalem");
            System.Net.HttpWebRequest request = (System.Net.HttpWebRequest) System.Net.HttpWebRequest.Create(targetUri);

Answer 1

我没有收到错误,但是出现"无效登录"消息,这让我觉得该表单实际上是一个Post请求.以下是Get Request示例:

using System;
using System.Net;
using System.Text;
using System.IO;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        StringBuilder sb = new StringBuilder();

        byte[] buf = new byte[8192];

        //do get request
        HttpWebRequest request = (HttpWebRequest)
            WebRequest.Create("http://sms-om.com/smspro/sendsms.php?user=HatemSalem");


        HttpWebResponse response = (HttpWebResponse)
            request.GetResponse();


        Stream resStream = response.GetResponseStream();

        string tempString = null;
        int count = 0;
        //read the data and print it
        do
        {
            count = resStream.Read(buf, 0, buf.Length);
            if (count != 0)
            {
                tempString = Encoding.ASCII.GetString(buf, 0, count);

                sb.Append(tempString);
            }
        }
        while (count > 0);
        Response.Write(sb.ToString());
    }
}

祝好运!

您当前尚未执行请求，请使用：

var response = request.GetResponse() as HttpWebResponse;

这是它实际上将从网络上获取数据并为您提供任何相关错误的关键点
