I'm trying to get the html code of certain webpage, I have a username and a password that are correct but i still can't get it to work, this is my code:
private void b开发者_JAVA百科uttondownloadfile_Click(object sender, EventArgs e)
{
NetworkCredentials nc = new NetworkCredentials("?", "?", "http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");
WebClient client = new WebClient();
client.Credentials = nc;
String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");
MessageBox.Show(htmlCode);
}
The MessageBox is just to test it, the problem is that every time I get to this line:
String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");
I get an exception:
The remote server returned an error: (401) Unauthorized.
How do I fix this?
In my case client.UseDefaultCredentials = true;
did the trick.
I have tried the following code and it is working.
private void Form1_Load(object sender, EventArgs e)
{
try
{
// Create Request
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(@"http://192.168.0.181/axis-cgi/com/ptz.cgi?move=up");
// Create Client
WebClient client = new WebClient();
// Assign Credentials
client.Credentials = new NetworkCredential("root", "a");
// Grab Data
string htmlCode = client.DownloadString(@"http://192.160.0.1/axis-cgi/com/ptz.cgi?move=up");
// Display Data
MessageBox.Show(htmlCode);
}
catch (WebException ex)
{
MessageBox.Show(ex.ToString());
}
}
Try to create a NetworkCredential
without that domain part:
NetworkCredential nc = new NetworkCredential("?", "?");
