使用Ksoap2调用Web Service加入SoapHeader

浏览数：42 / 时间：2015年06月09日

关于这个问题，如果使用百度都是前篇一律的代码，好不容易上了google才找到完整的方法，这里讲所有的代码都贴出来与大家分享。

首先是.NET写的后台代码

/// <summary>
    /// SoapHeader
    /// </summary>
    public class OwnSoapHeader:SoapHeader
    {
        public string UserName { get; set; }
        public string Password { get; set; }
    }

/// <summary>
    /// WebService1 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 
    // [System.Web.Script.Services.ScriptService]

    public class WebService1 : System.Web.Services.WebService
    {
        public OwnSoapHeader OwnSoapHeader;
        [WebMethod]
        [SoapHeader("OwnSoapHeader")]
        public string Login()
        {
            if (OwnSoapHeader != null)
            {
                return OwnSoapHeader.UserName + "," + OwnSoapHeader.Password;
            }
            return "尚未登录";
        }
    }

接下来是在浏览器中浏览查看我的接口，这里面有很重要的信息，包含了SoapHeader的名字以及参数

随后就是使用Ksoap2调用我的接口了

private void DoLogin() {
        new Thread() {
            @Override
            public void run() {
                Looper.prepare();
                // TODO Auto-generated method stub
                String sNameSpace = "http://tempuri.org/";
                String sMethodName = "Login";
                String sActionString = "http://tempuri.org/Login";
                String sURL = "http://192.168.1.101:8088/WebService1.asmx";

                SoapObject rpc = new SoapObject(sNameSpace, sMethodName);
　　　　　　　　　　//在这里加入了SoapHeader
                Element[] header = new Element[1];
　　　　　　　　//OwnSoapHeader与上图红色标记处名字一致
                header[0] = new Element().createElement(sNameSpace, "OwnSoapHeader ");
　　　　　　　　　　//UserName上图红色标记处名字一致
                Element username = new Element().createElement(sNameSpace,
                        "UserName");
                username.addChild(Node.TEXT, "admin");
                header[0].addChild(Node.ELEMENT, username);
　　　　　　　　　　//Password上图红色标记处名字一致
                Element pass = new Element().createElement(sNameSpace,
                        "Password");
                pass.addChild(Node.TEXT, "123");
                header[0].addChild(Node.ELEMENT, pass);

                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER12);

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

                HttpTransportSE ht = new HttpTransportSE(sURL);

                SoapObject soapObject = null;
                try {
                    ht.call(sActionString, envelope);

                    soapObject = (SoapObject) envelope.bodyIn;
                } catch (IOException ex) {
                    // TODO Auto-generated catch block
                    ex.printStackTrace();
                } catch (XmlPullParserException ex) {
                    // TODO Auto-generated catch block
                    ex.printStackTrace();
                }
                Bundle result = new Bundle();
                if (soapObject != null) {
                    result.putString("result", soapObject.toString());
                } else {
                    result.putString("result", sURL);
                }

                Message msg = new Message();
                msg.setData(result);
                msg.what = 1;
                handler.handleMessage(msg);
                Looper.loop();
            }
        }.start();
    }

    Handler handler = new Handler() {

        @Override
        public void handleMessage(Message msg) {
            // TODO Auto-generated method stub
            if (msg.what == 1) {
                Bundle result = msg.getData();
                String text = result.getString("result");
                Toast.makeText(MainActivity.this, text, Toast.LENGTH_LONG)
                        .show();
            }
        }
    };
