Contoh

Contoh kode berikut mengatur properti Referer.

// Create a 'HttpWebRequest' object.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
// Set referer property  to http://www.microsoft.com .
myHttpWebRequest->Referer = "http://www.microsoft.com";
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
// Display the contents of the page to the console.
Stream^ streamResponse = myHttpWebResponse->GetResponseStream();
StreamReader^ streamRead = gcnew StreamReader( streamResponse );
array<Char>^ readBuffer = gcnew array<Char>(256);
int count = streamRead->Read( readBuffer, 0, 256 );
Console::WriteLine( "\nThe contents of HTML page are......." );
while ( count > 0 )
{
   String^ outputData = gcnew String( readBuffer,0,count );
   Console::Write( outputData );
   count = streamRead->Read( readBuffer, 0, 256 );
}
Console::WriteLine( "\nHTTP Request  Headers :\n\n {0}", myHttpWebRequest->Headers );
Console::WriteLine( "\nHTTP Response Headers :\n\n {0}", myHttpWebResponse->Headers );
streamRead->Close();
streamResponse->Close();
// Release the response object resources.
myHttpWebResponse->Close();
Console::WriteLine( "Referer to the site is: {0}", myHttpWebRequest->Referer );

// Create a 'HttpWebRequest' object.
HttpWebRequest	myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);
// Set referer property  to http://www.microsoft.com .
myHttpWebRequest.Referer="http://www.microsoft.com";
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
// Display the contents of the page to the console.
Stream streamResponse=myHttpWebResponse.GetResponseStream();
StreamReader streamRead = new StreamReader( streamResponse );
Char[] readBuffer = new Char[256];
int count = streamRead.Read( readBuffer, 0, 256 );
Console.WriteLine("\nThe contents of HTML page are.......");	
while (count > 0)
{
    String outputData = new String(readBuffer, 0, count);
    Console.Write(outputData);
    count = streamRead.Read(readBuffer, 0, 256);
}
Console.WriteLine("\nHTTP Request  Headers :\n\n{0}",myHttpWebRequest.Headers);
Console.WriteLine("\nHTTP Response Headers :\n\n{0}",myHttpWebResponse.Headers);	
streamRead.Close();
streamResponse.Close();
// Release the response object resources.
myHttpWebResponse.Close();

' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
' Displaying the contents of the page to the console
Dim streamResponse As Stream = myHttpWebResponse.GetResponseStream()
Dim streamRead As New StreamReader(streamResponse)
Dim readBuffer(256) As [Char]
Dim count As Integer = streamRead.Read(readBuffer, 0, 256)
Console.WriteLine(ControlChars.Cr + "The contents of HTML page are.......")
While count > 0
    Dim outputData As New [String](readBuffer, 0, count)
    Console.Write(outputData)
    count = streamRead.Read(readBuffer, 0, 256)
End While
Console.WriteLine(ControlChars.Cr + "HTTP Request  Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebRequest.Headers)
Console.WriteLine(ControlChars.Cr + "HTTP Response Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebResponse.Headers)
' Release the response object resources.
streamRead.Close()
 streamResponse.Close()
myHttpWebResponse.Close()
Console.WriteLine("Referer to the site is:{0}", myHttpWebRequest.Referer)

Keterangan

Hati

WebRequest, HttpWebRequest, ServicePoint, dan WebClient usang, dan Anda tidak boleh menggunakannya untuk pengembangan baru. Gunakan HttpClient sebagai gantinya.

Jika properti AllowAutoRedirecttrue, properti Referer diatur secara otomatis saat permintaan dialihkan ke situs lain.

Untuk menghapus header HTTP Referer, atur properti Referer ke null.

Nota

Nilai untuk properti ini disimpan dalam WebHeaderCollection. Jika WebHeaderCollection diatur, nilai properti akan hilang.
