我正在编写一个控制台应用程序作为httplistener，并通过jquery使用它，它是完全正确的，但我想将它转换为https，但我不知道步骤

这是我的代码，我希望任何人都能很快解决它

这是用JScript.js文件编写的jquery代码

 $(function () {
    //this code is executed when the page's onload event fires
    $("#runSample1").click(function () {
        var userNameJS = $("#uName").val();
        var passwordJS = $("#passw").val();
        $.post("http://localhost:80/", { userName: userNameJS, password: passwordJS }, function (data) {
            alert(data);
        });

    });
});

这是html页面

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

    <script type="text/javascript" src="Scripts/jquery-1.4.1.js"> </script>

    <script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"> </script>
    <script type="text/javascript" src="Scripts/JScript.js"></script>
    <script type="text/javascript" src="Scripts/jquery-1.4.1-vsdoc.js"></script>
    <style type="text/css">
        .style1 {
            width: 109px;
        }
    </style>
</head>
<body>
<table>

    <tr>
        <td class="style1"><label >User Name</label></td>
        <td><input id="uName"  type="text" /></td>
    </tr>
    <tr>
        <td class="style1"><label >Password</label></td>
        <td><input id="passw"  type="password" /></td>
    </tr>
    <tr>
        <td class="style1"><input id="runSample1"  type="button" value="Send" style="width: 62px"/>  </td>
    </tr>
    </table>
</body>
</html>

并且httplistener代码是

        static void Main(string[] args)
        {
            if (!HttpListener.IsSupported)
            {
                Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.");
                return;
            }
            // Create a listener.
            HttpListener listener = new HttpListener();
            //listener.AuthenticationSchemes = AuthenticationSchemes.Negotiate;
            listener.Prefixes.Add("http://*:8080/");
            //listener.AuthenticationSchemes
            listener.Start();
            Console.WriteLine("Listening...");
            for (; ; )
            {
                HttpListenerContext ctx = listener.GetContext();
                new Thread(new Worker(ctx).ProcessRequest).Start();

        public void ProcessRequest()

            HttpListenerRequest request = context.Request;
            List<Person> eList = new List<Person>();

            }
            HttpListenerResponse response = context.Response;
            System.IO.StreamReader reader = new System.IO.StreamReader(request.InputStream, request.ContentEncoding);
            // S contain parameters and values
            string s = reader.ReadToEnd();
            string[] pairs = s.Split('&');

                formVars.Add(item[0],item[1]);
            }
            String userName = formVars["userName"].ToString();
            String password = formVars["password"].ToString();
            //To send any object as json to client
            DataContractJsonSerializer jsonObject = new DataContractJsonSerializer(typeof(List<Person>));
            System.IO.Stream output = response.OutputStream;
            MemoryStream ms = new MemoryStream();
            jsonObject.WriteObject(ms, eList);
            byte[] buffer = ms.ToArray();
            response.ContentType = "text/plain";
            response.ContentEncoding = System.Text.UTF8Encoding.UTF8;
            response.ContentLength64 = buffer.Length;
            //These headers to allow all browsers to get the response
            response.Headers.Add("Access-Control-Allow-Credentials", "true");
            response.Headers.Add("Access-Control-Allow-Origin", "*");
            response.Headers.Add("Access-Control-Origin", "*");

IE不是沙箱本地主机。FF和其他浏览器都这样做。他们认为对localhost的调用是对web的调用，这是不允许的。

您可以尝试添加

Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Access-Control-Origin: *

添加到HttpListener的标头。关于为什么需要这样做的一篇好论文可以在here上找到。
