I'm trying to log in to website. Following settings works when i use putty:
GET /WindchillCProdA/netmarkets/jsp/netmarkets/view.jsp HTTP/1.1
Host: www.host_address.com
Cookie: action_number=0
Authorization: Basic bG9naW46cGFzc3dvcmQ=
I've used following code to make the same thing in C#:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.webpage.com/WindchillCProdA/netmarkets/jsp/netmarkets/view.jsp");
request.Method = "GET";
CookieContainer gaCookies = new CookieContainer();
gaCookies.Add(new Cookie("action_number", "0") { Domain = request.Host });
request.Host = www.host_address.com;
request.CookieContainer = gaCookies;
request.UserAgent = "HTTP/1.1";
request.Headers["Authorization"] = "Basic " + "bG9naW46cGFzc3dvcmQ=";
I'm receiving:
The remote server returned an error: (401) Unauthorized.
I suspect that i have to fill somehow view.jsp because my parameters are not used in this case.
use post method and write on request stream the values,
i Checked the web site and i was redirected to another page the code should be as bellow
//there could be some hash check the scripts via inspect Element
string postData = String.Format("email={0}&newPassword={1}", "yourusername","yourPassword");
var request = (HttpWebRequest)WebRequest.Create("https://secure.systemsecure.com/host/login/23.htm");
getRequest.Method = WebRequestMethods.Http.Post;
getRequest.CookieContainer = new CookieContainer();

getRequest.ProtocolVersion = HttpVersion.Version10;
getRequest.AllowAutoRedirect = true;
getRequest.ContentType = "application/x-www-form-urlencoded";
byte[] byteArray = Encoding.ASCII.GetBytes(postData);
getRequest.ContentLength = byteArray.Length;
Stream newStream = getRequest.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();
var getResponse = (HttpWebResponse)getRequest.GetResponse();

After logged in, cookies are generated for subsequent requests.
I am trying to get cookies by sending a "POST" request.
In the response header, there is a "set-cookies" field and its value is like: "value1=value1,value2=value2......";
However, the CookieContainer i created for the HttpWebRequest is still empty.
So what is happening and how can I have my CookieContainer filled?
Any suggestion would be appreciated.

A server error in the 500 range means something gone wrong server side. From the looks of your request, I think it might be related to the Viewstate variable you are posting. The server will try to reconstruct the page according to your submitted state. It's not something you just copy and paste. Have you tried only sending the parameters that relate to the login itself (name, password, the name of the button clicked)?
For your work see fiddler run the same request and see the cookies match and other post parameters.
And also try :
postparameter= UrlEncode(postparameter)
Before converting them to byte and see if that works.
Maybe it works that way.
Why dont you go to the exact page you want to scrape in your browser and then export the full COOKIE set for manual attachment to your script's header?

The URL does not allow the application configuration.: The application settings do not allow one or more of the URLs. Internet Site URL and Canvas URL or domain URLs must be sub-domains of application domains.
I have some code that logs me into Facebook and it works fine as far as returning me the page you see right after you log in.
But I'm trying to request my actual profile after I log in rather than just my news feed.
So I'd have to send my email and password to the login page, then request my profile.
How can I keep the login data around while requesting my profile?
Here is what I've got
public static string logIn()
{
//get the cookies before you try to log in
CookieCollection cookies = new CookieCollection();
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.facebook.com");
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(cookies);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
cookies = response.Cookies;
response.Close();
//logging in
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create("https://www.facebook.com/login.php?login_attempt=1");
getRequest.CookieContainer = new CookieContainer();
getRequest.CookieContainer.Add(cookies);
getRequest.Method = WebRequestMethods.Http.Post;
getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
getRequest.AllowWriteStreamBuffering = true;
getRequest.ProtocolVersion = HttpVersion.Version11;
getRequest.AllowAutoRedirect = true;
getRequest.ContentType = "application/x-www-form-urlencoded";
//sending the email/password
byte[] byteArray = Encoding.ASCII.GetBytes("email=myemail#yahoo.com&pass=mypassword");
getRequest.ContentLength = byteArray.Length;
Stream newStream = getRequest.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();
//returns the source of the page after logging in
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
StreamReader sr = new StreamReader(getResponse.GetResponseStream());
string source = sr.ReadToEnd();
cookies.Add(getResponse.Cookies);
//tries to get my profile source
//everything works fine until here
getRequest = (HttpWebRequest)WebRequest.Create("http://www.facebook.com/myprofile");
getRequest.CookieContainer = new CookieContainer();
getRequest.CookieContainer.Add(cookies);
getRequest.Method = WebRequestMethods.Http.Get;
getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
getRequest.AllowWriteStreamBuffering = true;
getRequest.ProtocolVersion = HttpVersion.Version11;
getRequest.AllowAutoRedirect = true;
getRequest.ContentType = "application/x-www-form-urlencoded";
getResponse = (HttpWebResponse)getRequest.GetResponse();
sr = new StreamReader(getResponse.GetResponseStream());
source = sr.ReadToEnd();
getResponse.Close();
return source;
}
I've tried several ways of doing this and I have gotten it to return my profile, but it returns it as if I was not logged in and you can't actually view my profile (because it is set to private)
So I need my login info to be included somehow when requesting my profile.
This had me stumped for a while when I was making something similar. You need to make sure you're setting the proper cookies for your request after you've logged in. Try adding the new cookies to the CookieCollection object before applying them to your last request.
// ^ previous code ^
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
StreamReader sr = new StreamReader(getResponse.GetResponseStream());
string source = sr.ReadToEnd();
Uri facebookPage = new Uri("http://www.facebook.com"); // .GetCookies() only accepts a Uri
cookies.Add(request.CookieContainer.GetCookies(facebookPage));
getResponse.Close(); // Always make sure you close your responses
// V requesting your profile code V
You have to start a CookieCollection at the beginning and use it for all requests.
A CookieCollection updates itself with new cookies whenever you do a request so using cookies.Add() was also messing it up.
But I got it working fine now.
I have task of uploading file to java servlet. I installed Fiddler to see where web requests are sent and what post data is sent. After logging into java servlet using HttpWebRequest GET method I receive in cookies SessionId. So I was using this SessionId in headers to create POST request to the web server where servlet is. But in response I receive message that "session is time out. Try to login again." But if I use application through user interface I have the one SessionId for all application which is sent in headers with each request.
This application is running in bank so I was thinking if they have some security against scraping.
Am I thinking in a right way? Any help will be appreciated.
Thanks, Elena

If you are uploading file using HttpWebRequest, you must specify content headers correct.
Content must be specified as Content-Type: multipart/form-data
sample snippet
string DataBoundary = "-----------------------------" + DateTime.Now.Ticks.ToString("x");
string contentType = "multipart/form-data; boundary=" + DataBoundary ;
req.Method = "POST";
req.ContentType = contentType ;
req.UserAgent = userAgent;
req.CookieContainer = new CookieContainer();
req.ContentLength = formData.Length;
