首先，需要從SoapHeader派生一個類，全部程式碼如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services.Protocols;

namespace wolame
{
    public class MySoapHeader: SoapHeader
    {
        public string _UserID;
        public string _Password;
        public string _InParam;

        public MySoapHeader()
        {

        }


        public string UserID
        {
            get { return _UserID; }
            set { _UserID = value; }
        }

        public string Password
        {
            get { return _Password; }
            set { _Password = value; }
        }


        public string InParam
        {
            get { return _InParam; }
            set { _Password = value; }
        }


        private bool IsValid(string sUserID, string sPasswd,  out string sMsg)
        {
            sMsg = "";
            try
            {
                if(sUserID == "wolame" && sPasswd == "facai_888")
                {
                    sMsg = _InParam;
                    return true;
                }
                else
                {
                    sMsg = "fuck your ass!";
                    return false;
                }

            }
            catch
            {
                sMsg = "error";
                return false;
            }
        }

        public bool IsValid(out string sMsg)
        {
            return IsValid(_UserID, _Password, out sMsg);
        }
    }
}
 

然後在介面處增加判斷：

 public class wolameservice : System.Web.Services.WebService
    {
        public MySoapHeader myHeader;


        //使用者通過簡訊驗證碼登入
        [SoapHeader("myHeader")]
        [WebMethod]
        public string login_by_code()
        {
            string sMsg = "";
            if (myHeader == null)
            {
                return "error";
            }

            if (!myHeader.IsValid(out sMsg))
            {
                return sMsg;
            }

            UserManage user = new UserManage();
            return user.login_by_code(sMsg);
        }
	}
 

.net客戶端呼叫方式：

        public string GetSystemParam()
        {
            ClientService.ClientService cs = new ClientService.ClientService();

            //for safty
            ClientService.MySoapHeader header = new ClientService.MySoapHeader();
            header._UserID = "ghzx2017";
            header._Password = "godgivemehope";
            cs.MySoapHeaderValue = header;
            //


            string sMsg = cs.GetSystemParam();
            return sMsg;
        }
 

安卓客戶端呼叫：

    private void login(){
        String sToken = "";

        Message msg = new Message();
        try
        {
            String nameSpace = getResources().getString(R.string.namespace);
            String endPoint = getResources().getString(R.string.endpoint);
            String methodName = "login";
            String soapAction = nameSpace + methodName;

            Element[] header = new Element[1];
            header[0] = new Element().createElement(nameSpace, "MySoapHeader");

            Element uname = new Element().createElement(nameSpace, "_UserID");
            uname.addChild(Node.TEXT, "ghzx2017");
            header[0].addChild(Node.ELEMENT, uname);

            Element pass = new Element().createElement(nameSpace, "_Password");
            pass.addChild(Node.TEXT, "godgivemehope");
            header[0].addChild(Node.ELEMENT, pass);

            Element content = new Element().createElement(nameSpace, "_InParam");
            String sParam = buildParam();
            content.addChild(Node.TEXT, sParam);
            header[0].addChild(Node.ELEMENT, content);


            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);

            SoapObject so = new SoapObject(nameSpace, methodName);

            envelope.headerOut = header;
            envelope.bodyOut = so;
            envelope.dotNet = true;
            envelope.setOutputSoapObject(so);

            HttpTransportSE transportSE = new HttpTransportSE(endPoint);
            transportSE.call(soapAction, envelope);

            SoapObject object = (SoapObject)envelope.bodyIn;
            SoapPrimitive detail = (SoapPrimitive)envelope.getResponse();
            sToken = detail.toString();

            msg.obj = sToken;
            msg.what = 1;

        }
        catch (Exception ex)
        {
            msg.obj = ex.getMessage();
            msg.what = -1;
            dialog.dismiss();
        }

        finally {
            handler.sendMessage(msg);
        }
    }
