範例

下列程式碼範例會將 Method 屬性設定為 POST。The following code example sets the Method property to POST.

// Set the 'Method' property of the 'Webrequest' to 'POST'.
myHttpWebRequest->Method = "POST";
Console::WriteLine( "\nPlease enter the data to be posted to the (http://www.contoso.com/codesnippets/next.asp) Uri :" );

// Create a new String* Object* to POST data to the Url.
String^ inputData = Console::ReadLine();

String^ postData = String::Concat( "firstone= ", inputData );
ASCIIEncoding^ encoding = gcnew ASCIIEncoding;
array<Byte>^ byte1 = encoding->GetBytes( postData );

// Set the content type of the data being posted.
myHttpWebRequest->ContentType = "application/x-www-form-urlencoded";

// Set the content length of the String* being posted.
myHttpWebRequest->ContentLength = byte1->Length;

Stream^ newStream = myHttpWebRequest->GetRequestStream();

newStream->Write( byte1, 0, byte1->Length );
Console::WriteLine( "The value of 'ContentLength' property after sending the data is {0}", myHttpWebRequest->ContentLength );

// Close the Stream Object*.
newStream->Close();
// Set the 'Method' property of the 'Webrequest' to 'POST'.
myHttpWebRequest.Method = "POST";
Console.WriteLine ("\nPlease enter the data to be posted to the (http://www.contoso.com/codesnippets/next.asp) Uri :");

// Create a new string object to POST data to the Url.
string inputData = Console.ReadLine ();


string postData = "firstone=" + inputData;
ASCIIEncoding encoding = new ASCIIEncoding ();
byte[] byte1 = encoding.GetBytes (postData);

// Set the content type of the data being posted.
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";

// Set the content length of the string being posted.
myHttpWebRequest.ContentLength = byte1.Length;

Stream newStream = myHttpWebRequest.GetRequestStream ();

newStream.Write (byte1, 0, byte1.Length);
Console.WriteLine ("The value of 'ContentLength' property after sending the data is {0}", myHttpWebRequest.ContentLength);

// Close the Stream object.
newStream.Close ();

' Set the 'Method' property of the 'Webrequest' to 'POST'.
myHttpWebRequest.Method = "POST"

Console.WriteLine(ControlChars.Cr + "Please enter the data to be posted to the (http://www.contoso.com/codesnippets/next.asp) Uri :")
' Create a new string object to POST data to the Url.
Dim inputData As String = Console.ReadLine()
Dim postData As String = "firstone" + ChrW(61) + inputData
Dim encoding As New ASCIIEncoding()
Dim byte1 As Byte() = encoding.GetBytes(postData)
' Set the content type of the data being posted.
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded"
' Set the content length of the string being posted.
myHttpWebRequest.ContentLength = byte1.Length
Dim newStream As Stream = myHttpWebRequest.GetRequestStream()
newStream.Write(byte1, 0, byte1.Length)
Console.WriteLine("The value of 'ContentLength' property after sending the data is {0}", myHttpWebRequest.ContentLength)
newStream.Close()

備註

Method 屬性可以設定為任何 HTTP 1.1 通訊協定動詞: GET、HEAD、POST、PUT、DELETE、TRACE 或 OPTIONS。The Method property can be set to any of the HTTP 1.1 protocol verbs: GET, HEAD, POST, PUT, DELETE, TRACE, or OPTIONS.

如果 ContentLength 屬性設定為-1 以外的任何值,則 Method 屬性必須設定為上傳資料的通訊協定屬性。If the ContentLength property is set to any value other than -1, the Method property must be set to a protocol property that uploads data.
