如何在 asp.net 中向 context.response 添加新的 header

Question

我对 asp.net 很陌生。我正在构建一个现有项目，其中 js 文件中的用户名和密码已加密，并且对 .aspx.cs 文件进行了 ajax 函数调用。这个 ashx.cs 文件解密它们，然后将它们插入数据库 table。现在我想包含一个名为 "Domain" 的新字段，但我不知道应该如何为它创建一个 header，以便将它从 js 传递到 ashx.cs file.My 问题可能很愚蠢，但我已经为此苦苦挣扎了一段时间，并感谢您的帮助。我尝试对域使用 context.Response.AddHeader，但我不知道应该向其中传递什么值..

"RUN" 和 "RUP" 似乎已经在某处创建，我无法找到它们以遵循相同的域 header..

js 文件：

function Register() {

    if (ValidateRegisterWindow()) {

        var URL = "SecureChatServer.ashx";
        if (URL == null) { alert("Request URL is Empty"); }
        else {
            username = Encrypt(document.getElementById('NewUserName').value, EncryptionKey);
            password = Encrypt(document.getElementById('NewPassword').value, EncryptionKey);
            domain = Encrypt(document.getElementById('NewDomain').value, EncryptionKey);

            AjaxRequest(ProcessRegisterResponse, URL, "POST", '', '', { RequestCode: 'SC006', RUN: username, RUP: password}); //how to pass domain here??
        }
    }

}


function ProcessRegisterResponse() {

    var ResponseStatus = GetHeader(ResponseHeaderJSON, 'ResponseStatus');
    if (ResponseStatus == "RS-OK") {

        ShowAlertMessage("Registration Sucessful", "", "User Registered and Logged in Sucessfully");
        CurrentUser = document.getElementById('NewUserName').value;
        LoginEvents(CurrentUser, true);
        ClearRegisterWindow();


    }
    else if (ResponseStatus == "RS-Failed") {

        ShowErrorBox("Registration Error", "This username cannot be registered ,please try a different username");

    }
    else {

        ShowErrorBox("Unknown Error :Code-01 " + ResponseStatus, "Request cannot be processed ,please try again.");

    }
}

ashx.cs 文件：

  #region Handle Add New User Request
            case "SC006":  //indicates request to add new user
                {
                    string UserName, Password;
                    UserName = Decrypt(context.Request.Headers["RUN"], EncryptionKey);
                    Password = Decrypt(context.Request.Headers["RUP"], EncryptionKey);
                    Users newuser = new Users();

                    try
                    {
                        if (newuser.AddUser(UserName, Password, SessionID, UserIPAddress))
                        {
                            context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-OK'");
                        }
                        else
                        {
                            context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-Failed'");
                        }
                    }
                    catch (Exception e)
                    {
                        Debug.WriteLine("Failed Request SC006 : " + e.ToString());
                        context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-Exception'");

                    }
                }
                break;

            #endregion
