httpHandler

创建继承自IHttpHandler的类型，处理特定的请求。

 

Public Class XXXHandler: Implements IHttpHandler
    Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
        Dim action As String = context.Request.QueryString("action")
        Select Case action
            Case "dosomething"
                doSomeThing(context)
            Case Else
                NonAction(context)
        End Select
    End Sub
 
    Private Sub NonAction(ByRef context As HttpContext)
        Dim content As String = "Hello world!"
        context.Response.ContentType = "text/plain"
        context.Response.Write(content)
    End Sub 

    Public Overloads ReadOnly Property IsReusable() As Boolean
        Get
            Return False
        End Get
    End Property

End Class

 

web.config配置：

<httpHandlers>
      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </httpHandlers>
