如何维护httpwebrequest的状态

问题描述

嗨我已经使用以下代码进行了身份验证，并且现在使用此身份验证成功实现了它，我还必须继续从url"http://localhost:8080/geonetwork/srv/en/xml.metadata.get"获取响应
这是我用来获取身份验证的代码

 受保护的 无效 Page_Load(对象发​​件人，EventArgs e)
    {
        字符串 RequestXML = " < request>"  +
                            " <用户名> admin</用户名>"  +
                            " <密码> admin</密码></request>" ;
        字符串 ServerURL = "  http://localhost:8080/geonetwork/srv/en/xml.user.login";
        字符串 ResponseXML = postRequest(RequestXML，ServerURL);
        Label1.Text = ResponseXML;
    }

    私有 字符串 postRequest(字符串 RequestXML，字符串 ServerURL)
    {
         int 超时=  90000 ;
         int  connectionLimit =  10 ;
        字符串 responseXML = 字符串 .Empty;
        尝试
        {
            HttpWebRequest webRequest =(HttpWebRequest)WebRequest.Create(ServerURL);
            webRequest.Timeout =超时;
            webRequest.KeepAlive =  true ;
            webRequest.ServicePoint.ConnectionLimit = connectionLimit;
            webRequest.Method = "  POST" ;
            webRequest.ContentType = " 文本/xml" ;
            字节 [] byteArray = Encoding.UTF8.GetBytes(RequestXML);
            流strm = webRequest.GetRequestStream();
            strm.Write(byteArray， 0 ，byteArray.Length);
            strm.Close();
            HttpWebResponse webResponse =(HttpWebResponse)webRequest.GetResponse();
            编码enc = Encoding.GetEncoding("  utf-8" );
            StreamReader reader = 新 StreamReader(webResponse.GetResponseStream()，enc);
            responseXML = reader.ReadToEnd();
            reader.Close();
            webResponse.Close();
        }
        捕获(例外)
        {
            扔(例如)；
        }
        返回 responseXML;
    } 

使用上面的代码，我必须从该URL"http://localhost:8080/geonetwork/srv/en/xml.metadata.get"中获取响应，而不会丢失身份验证，请pl帮助我做到这一点

hii have used the following code to get authenticated and i successfully achieved it now using this authentication i have to futher proceed to get response from the url"http://localhost:8080/geonetwork/srv/en/xml.metadata.get"
this is the code i have used to get authentication

protected void Page_Load(object sender, EventArgs e)
    {
        string RequestXML = "<request>" +
                            "<username>admin</username>" +
                            "<password>admin</password></request>";
        string ServerURL = "http://localhost:8080/geonetwork/srv/en/xml.user.login";
        string ResponseXML = postRequest(RequestXML, ServerURL);
        Label1.Text = ResponseXML;
    }

    private string postRequest(String RequestXML, string ServerURL)
    {
        int timeout = 90000;
        int connectionLimit = 10;
        string responseXML = string.Empty;
        try
        {
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(ServerURL);
            webRequest.Timeout = timeout;
            webRequest.KeepAlive = true;
            webRequest.ServicePoint.ConnectionLimit = connectionLimit;
            webRequest.Method = "POST";
            webRequest.ContentType = "text/xml";
            byte[] byteArray = Encoding.UTF8.GetBytes(RequestXML);
            Stream strm = webRequest.GetRequestStream();
            strm.Write(byteArray, 0, byteArray.Length);
            strm.Close();
            HttpWebResponse webResponse =(HttpWebResponse)webRequest.GetResponse();
            Encoding enc = Encoding.GetEncoding("utf-8");
            StreamReader reader = new StreamReader(webResponse.GetResponseStream(),enc);
            responseXML = reader.ReadToEnd();
            reader.Close();
            webResponse.Close();
        }
        catch (Exception ex)
        {
            throw (ex);
        }
        return responseXML;
    }

using the above code i have to get the response from this url "http://localhost:8080/geonetwork/srv/en/xml.metadata.get" without losing the authentication pl help me in doing this
