[英]The remote server returned an error: (401) Unauthorized
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: 我正在尝试获取某些网页的html代码,我有一个正确的用户名和密码,但我仍然无法让它工作,这是我的代码:
private void buttondownloadfile_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: MessageBox只是为了测试它,问题是每次我到达这一行:
String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");
I get an exception: 我得到一个例外:
The remote server returned an error: (401) Unauthorized. 远程服务器返回错误:(401)未经授权。
How do I fix this? 我该如何解决?
In my case client.UseDefaultCredentials = true;
在我的情况下client.UseDefaultCredentials = true;
did the trick. 做了伎俩。
I have tried the following code and it is working. 我尝试了以下代码,它正在工作。
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());
}
}
尝试创建没有该域部分的NetworkCredential
:
NetworkCredential nc = new NetworkCredential("?", "?");
