如何将Access-Control-Allow-Origin添加到我在VB中创建的ASMX Web服务中？

Question

我有一个非常简单的ASMX页面......

Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.Web.Script.Services

<WebService(Namespace:="http://localhost/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ScriptService()> _
Public Class JSWSGuessWeddingsByDay
    Inherits System.Web.Services.WebService


    <WebMethod()> _
    <ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=True)> _
    Public Function HowManyPeopleAreGettingMarriedToday() As Integer

        Dim weddingCount As New Controller.Member.MemberDal

        Return weddingCount.GuessWeddingsByDay(Nothing)

    End Function
End Class

如何将Access-Control-Allow-Origin添加到响应标头中，以便多个网站可以使用AJAX使用Web服务？

您是否尝试在返回声明之前添加此内容？：

Response.AddHeader("Access-Control-Allow-Origin","*")
