Android AsyncTask+Soap 的简单使用

Soap 描述如下：

基于类对象的传输协议。
SOAP封装（envelop），它定义了一个框架，描述消息中的内容是什么，是谁发送的，谁应当接受并处理它以及如何处理它们；
SOAP编码规则（encoding rules），它定义了一种序列化机制，用于表示应用程序需要使用的数据类型的实例；
SOAP RPC表示（RPC representation），它定了一个协定，用于表示远程过程调用和应答；
SOAP绑定（binding），它定义了SOAP使用哪种协议交换信息。使用HTTP/TCP/UDP协议都可以。

android 使用soap 步骤如下：

1.引用第三方库

    compile files('libs/ksoap2-android-assembly-3.6.1-jar-with-dependencies.jar')

2.创建一个工具栏方便进行网络请求AsyncTaskSoapUtil.java

package net.sytm.soapdemo.util;import android.os.AsyncTask;import org.ksoap2.SoapEnvelope;import org.ksoap2.SoapFault;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;import org.xmlpull.v1.XmlPullParserException;import java.io.IOException;import java.util.Map;import java.util.Set;/** * Created by aoc on 2016/8/31. */public class AsyncTaskSoapUtil extends AsyncTask<Void, Void, String> {    private String name;    private String url;    private String action;    private Map<String, String> param;    private Callback callback;    public AsyncTaskSoapUtil(String name, String url, String action, Map<String, String> param) {        this.name = name;        this.url = url;        this.action = action;        this.param = param;    }    public void setCallback(Callback callback) {        this.callback = callback;    }    @Override    protected void onPreExecute() {        callback.onPre();    }    @Override    protected String doInBackground(Void... voids) {        String xml = "";        SoapObject request = new SoapObject(name, action);        Set<Map.Entry<String, String>> set = param.entrySet();        for (Map.Entry<String, String> entry : set) {            request.addProperty(entry.getKey(), entry.getValue());        }        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);        envelope.dotNet = true;        envelope.bodyOut = request;        HttpTransportSE transportSE = new HttpTransportSE(url);        try {            transportSE.call(getSoapAction(name, action), envelope);            SoapObject result = (SoapObject) envelope.getResponse();            //Object bodyIn =  envelope            xml = result.toString();        }        catch (SoapFault soapFault) {            soapFault.printStackTrace();        }        catch (XmlPullParserException e) {            e.printStackTrace();        }        catch (IOException e) {            e.printStackTrace();        }        return xml;    }    @Override    protected void onPostExecute(String data) {        callback.onPost(data);    }    public interface Callback {        void onPre();        void onPost(String data);    }    private String getSoapAction(String name, String action) {        StringBuilder builder = new StringBuilder();        builder.append(name);        builder.append(action);        return builder.toString();    }}

3.使用示例

    private void send(String value1, String value2) {        //接口        String action = "MemberLogin";        //参数        NameValueUtil nameValueUtil = new NameValueUtil();        nameValueUtil.put("phone", value1);        nameValueUtil.put("password", value2);        AsyncTaskSoapUtil taskUtil = new AsyncTaskSoapUtil(Constant.name, Constant.url, action, nameValueUtil.getParam());        taskUtil.setCallback(callback);        taskUtil.execute();    }    AsyncTaskSoapUtil.Callback callback = new AsyncTaskSoapUtil.Callback() {        @Override        public void onPre() {        }        @Override        public void onPost(String data) {            resultView.setText(data);        }    };
