如何让服务器对uid与pwd进行验证，并将验证结果返回给客户端

Question

请教一下：
现在有这样一个需求，假设服务器地址 www.fuq.com,客户机运行的软件通过 http://www.fuq.com/uid=UserName&pwd=PordWord来发送请求，服务器对uid与pwd进行验证，并将验证结果返回给客户端。这采用什么样的方式来实现？

Answer 1

webclient吧

Answer 2

如果你想远程在客户端验证用户名和密码，可用通过WEBSERVICE服务来实现

在url中提交用户名密码会有安全问题

不太清楚你问的是哪一端的问题。发请求可以使用HttpWebRequest,WebClient类

我客户端为c/s程序，代码如下： 

private void button1_Click(object sender, EventArgs e)
 {
            StringBuilder sbTemp = new StringBuilder();
            //POST
            sbTemp.Append("uid=" + UserName.Text.Trim() + "&pwd=" + Pwd.Text.Trim());
            byte[] bTemp = System.Text.Encoding.GetEncoding("GBK").GetBytes(sbTemp.ToString());
            //byte[] bTemp = System.Text.Encoding.ASCII.GetBytes(sbTemp.ToString());
            String postReturn = doPostRequest("http://www.fuq.com/default.aspx",bTemp);
            if (postReturn.IndexOf("xzok") >= 0)
            {
                labMsg.Text = "正常";
            }
            else
            {
                labMsg.Text = "非法";
            }
         
}
private static String doPostRequest(string url, byte[] bData)
{
         
            System.Net.HttpWebRequest hwRequest;
            System.Net.HttpWebResponse hwResponse;
            string strResult = string.Empty;
            try
            {
                hwRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
                hwRequest.Timeout = 5000;
                hwRequest.Method = "POST";
                hwRequest.ContentType = "application/x-www-form-urlencoded";
                hwRequest.ContentLength = bData.Length;

                System.IO.Stream smWrite = hwRequest.GetRequestStream();
                smWrite.Write(bData, 0, bData.Length);
                smWrite.Close();
            }
            catch (System.Exception err)
            {
                WriteErrLog(err.ToString());
                return strResult;
            }
            //get response
            try
            {
                hwResponse = (HttpWebResponse)hwRequest.GetResponse();
                StreamReader srReader = new StreamReader(hwResponse.GetResponseStream(), Encoding.ASCII);
                strResult = srReader.ReadToEnd();
                srReader.Close();
                hwResponse.Close();
             }
            catch (System.Exception err)
            {
                WriteErrLog(err.ToString());
            }
            return strResult;
}

服务器端为一个网站，http://www.fuq.com/default.aspx代码如下：

 protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString["uid"] != null || Request.QueryString["pwd"] != null)
        {
            if (Request.QueryString["uid"] == "zxl" || Request.QueryString["pwd"] == "761130")
            {
                Response.Write("xzok");
            }
            else
            {
                Response.Write("xzerror");
            }
        }
        else
        {
            Response.Write("xzerror");
        }
    }

可是我在客户端输入zxl,761130却得不到"正常"，不知代码有什么问题？

我感觉问题是服务器端接收的代码不对，但不知该如何去写？
