示例1: SimpleListenerExample
Public Shared Sub SimpleListenerExample(prefixes As String())
If Not HttpListener.IsSupported Then
Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.")
Return
End If
' URI prefixes are required,
' for example "http://contoso.com:8080/index/".
If prefixes Is Nothing Or prefixes.Length = 0 Then
Throw New ArgumentException("prefixes")
End If
' Create a listener
Dim listener = New HttpListener()
For Each s As String In prefixes
listener.Prefixes.Add(s)
Next
listener.Start()
Console.WriteLine("Listening...")
' Note: The GetContext method blocks while waiting for a request.
Dim context As HttpListenerContext = listener.GetContext()
Console.WriteLine("Listening...")
' Obtain a response object
Dim request As HttpListenerRequest = context.Request
' Construct a response.
Dim response As HttpListenerResponse = context.Response
Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
' Get a response stream and write the response to it.
response.ContentLength64 = buffer.Length
Dim output As System.IO.Stream = response.OutputStream
output.Write(buffer, 0, buffer.Length)
'You must close the output stream.
output.Close()
listener.Stop()
