HttpListenerRequest.InputStream 屬性

定義

取得包含用戶端所傳送之主體資料的資料流。

public:
 property System::IO::Stream ^ InputStream { System::IO::Stream ^ get(); };
public System.IO.Stream InputStream { get; }
member this.InputStream : System.IO.Stream
Public ReadOnly Property InputStream As Stream

屬性值

可讀取的 Stream 物件,包含用戶端在要求的主體中所傳送的位元組。 如果沒有資料隨要求傳送,則這個屬性會傳回 Null

範例

下列程式代碼範例示範如何使用這個屬性來讀取以要求傳送的數據。

public static void ShowRequestData (HttpListenerRequest request)
{
    if (!request.HasEntityBody)
    {
        Console.WriteLine("No client data was sent with the request.");
        return;
    }
    System.IO.Stream body = request.InputStream;
    System.Text.Encoding encoding = request.ContentEncoding;
    System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
    if (request.ContentType != null)
    {
        Console.WriteLine("Client data content type {0}", request.ContentType);
    }
    Console.WriteLine("Client data content length {0}", request.ContentLength64);

    Console.WriteLine("Start of client data:");
    // Convert the data to a string and display it on the console.
    string s = reader.ReadToEnd();
    Console.WriteLine(s);
    Console.WriteLine("End of client data:");
    body.Close();
    reader.Close();
    // If you are finished with the request, it should be closed also.
}
Public Shared Sub ShowRequestData(ByVal request As HttpListenerRequest)
    If Not request.HasEntityBody Then
        Console.WriteLine("No client data was sent with the request.")
        Return
    End If

    Dim body As System.IO.Stream = request.InputStream
    Dim encoding As System.Text.Encoding = request.ContentEncoding
    Dim reader As System.IO.StreamReader = New System.IO.StreamReader(body, encoding)

    If request.ContentType IsNot Nothing Then
        Console.WriteLine("Client data content type {0}", request.ContentType)
    End If

    Console.WriteLine("Client data content length {0}", request.ContentLength64)
    Console.WriteLine("Start of client data:")
    ' Convert the data to a string and display it on the console.
    Dim s As String = reader.ReadToEnd()
    Console.WriteLine(s)
    Console.WriteLine("End of client data:")
    body.Close()
    reader.Close()
    ' If you are finished with the request, it should be closed also.
End Sub

備註

例如,如果用戶端使用 HTTP POST 方法) 傳輸資料 (,則此方法傳回的數據流會包含該數據。

注意

關閉要求並不會關閉這個屬性傳回的數據流。 當您不再需要數據流時,應該呼叫 Close 方法來關閉它。
