以编程方式登录到使用IIS身份验证的网站

Question

Hi all am trying to login to a website programmatically.I have already worked on this but is was a php page and i used the below code (found some where on Stack Overflow) to login to it and it worked great.

 private static string GetDataFromPHP(string formUrl, string getUrl, string username, string password, out bool status)
        {

            try
            {

                string formParams = string.Format("access_login={0}&access_password={1}", username, password);
                string cookieHeader;
                WebRequest req = WebRequest.Create(formUrl);
                req.ContentType = "application/x-www-form-urlencoded";
                req.Method = "POST";
                byte[] bytes = Encoding.ASCII.GetBytes(formParams);
                req.ContentLength = bytes.Length;
                using (Stream os = req.GetRequestStream())
                {
                    os.Write(bytes, 0, bytes.Length);
                }

                WebResponse resp = req.GetResponse();
                cookieHeader = resp.Headers["Set-cookie"];
                string pageSource;

                WebRequest getRequest = WebRequest.Create(getUrl);
                getRequest.Headers.Add("Cookie", cookieHeader);
                WebResponse getResponse = getRequest.GetResponse();
                using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
                {
                    pageSource = sr.ReadToEnd();
                }
                status = true;

                return pageSource;
            }



            catch (System.Exception ex)
            {
                status = false;
                return string.Empty;
            }

        }

Where access_login & access_password is the name of the input box that accepts the credentials.I have no clue how to implement it for a iis Login prompt as shown below.Please help

Answer 1

If you can login through a browser and use Fiddler to intercept the request, you can use the Fiddler add-on Request-To-Code to generate C# code that will perform the request. The generated code would probably be a good place for you to start at least.

I have successfully used Fiddler with Request-To-Code in similar situations.

Try using HttpWebRequest class and NetworkCredentials classes to accomplish this.

Here is a piece of code that should get you in right direction.

// Create Request
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.yourdomain/whatever");

// Create Client
WebClient client = new WebClient();

// Assign Credentials
client.Credentials = new NetworkCredential("user", "password");

// Grab Data
string htmlCode = client.DownloadString("http://www.yourdomain/whatever");
