Question

最近我参与了WCF创建，当我尝试使用它时，我遇到了跨域问题，通过从$ .ajax函数发送数据。

  var dto = { };
  dto.Id = 1;
  dto.Name = "Test";

  var DTO = { 'jsonMesssage': dto };

  $.ajax({
      type: "POST",
      contentType: "application/json; charset=utf-8",
      url: "http://localhost/JsonService/ProcessMessage",
      data: JSON.stringify(DTO),
      dataType: "json",
      crossDomain:true,
      success: function(result) {
        console.log(result.d);
      },
      error: function(a, b, c) {
        console.log(a, b, c);
      }

我找到了人们如何解决那些托管在IIS上的WCF服务的方式，但我有其他情况，因为WCF托管在.exe进程内

protected void Application_BeginRequest(object sender, EventArgs e) 
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

    if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
    {
        HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
        HttpContext.Current.Response.End();
    }
}

但如何实现相同，让拦截器能够正确修复跨域问题？
