Question

I have tried so many ways but failed to logged in purevolume.com programmatically!

login URL: http://www.purevolume.com/login

can anybody give it a try and provide sample code to achieve this.

Something like this should work… You need to do an http post request and send your username and password. To remain “logged in” you need a cookie container that you then reuse for all other requests.

Edit: Updated code that is tested. An initial GET request to /login was needed to have the session cookie before doing the POST login. I’ve also added some HTTP headers to make it identical to a “normal” request from a browser.

void Main()
{
    //We need a container to store the cookies in.
    CookieContainer cookies = new CookieContainer();

    //Request login page to get a session cookie
    GETHtml("http://www.purevolume.com/login", cookies);

    //Now we can do login
    Login("some-user-name", "some-password", cookies);
}

public bool Login(string Username, string Password, CookieContainer cookies)
{
    string poststring = string.Format("username={0}&password={1}&user_login_button.x=63&user_login_button.y=13&user_login_button=login",
                                Username, Password);
    byte[] postdata = Encoding.UTF8.GetBytes(poststring);

    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.purevolume.com/login");
    webRequest.CookieContainer = cookies;
    webRequest.Method = "POST";
    webRequest.Referer = "http://www.purevolume.com/login";
    webRequest.Headers.Add("origin", "http://www.purevolume.com");
    webRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.5.21022;";
    webRequest.ContentType = "application/x-www-form-urlencoded";
    webRequest.ContentLength = postdata.Length;
    using (Stream writer = webRequest.GetRequestStream())
        writer.Write(postdata, 0, postdata.Length);

    using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
    {
        //We need to add any response cookies to our cookie container
        cookies.Add(webResponse.Cookies);

        //Only for debug
        using (var stream = new StreamReader(webResponse.GetResponseStream()))
            System.Diagnostics.Debug.WriteLine(stream.ReadToEnd());

        return (webResponse.StatusCode == HttpStatusCode.OK);
    }
}

public string GETHtml(string url, CookieContainer cookies)
{
    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
    webRequest.CookieContainer = cookies;
    webRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.5.21022;";
    webRequest.Referer = "http://www.purevolume.com/login";

    using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
    {       
        //We need to add any response cookies to our cookie container           
        cookies.Add(webResponse.Cookies);

        using (var stream = new StreamReader(webResponse.GetResponseStream()))
            return stream.ReadToEnd();
    }
}
