android调用webservice接口获取信息

android调⽤webservice接⼝获取信息

我的有⼀篇博客上讲了如何基于CXF搭建webservice，service层的接⼝会被部署到tomcat上，这⼀篇我就讲⼀下如何在安卓

中调⽤这些接⼝传递参数。

1.在lib中放⼊ksoap2的jar包并导⼊

2.在xml 配置⽂件中加⼊：

3.接下来就要通过代码调⽤借⼝了

String WSDL_URI = "http://localhost:8080/WebService4/getNewIdPort?wsdl";//wsdl 的uri

String namespace = "http://services.he.TSD/";//namespace

String methodName = "getNew";//要调⽤的⽅法名称

// 创建HttpTransportSE对象

HttpTransportSE ht = new HttpTransportSE(WSDL_URI);

ht.debug = true;

// 使⽤soap1.1协议创建Envelop对象

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// 实例化SoapObject对象

SoapObject object = new SoapObject(namespace, methodName);

// 设置参数

object.addProperty("arg0", "hhh");

// 将SoapObject对象设置为SoapSerializationEnvelope对象的传出SOAP消息

envelope.bodyOut = object;//由于是发送请求，所以是设置bodyOut

envelope.dotNet =false;

envelope.setOutputSoapObject(object);

try{

// 调⽤webService

ht.call(null, envelope);

System.out.println("回传的值 ："+envelope.getResponse());

}

catch (Exception e) {

e.printStackTrace();

String msg=e.getMessage();

System.out.println(msg);

}

4.若webservice接收不到android传来的值：

（1）参数名不对

（2）.net的webservice要将envelope.dotNet =true，否则envelope.dotNet =false

5.由于是部署到tomcat上的，为了同处于⼀个⽹段，要⼿机和电脑连⼀个wifi。 ipv4查找⽤window+R，接着cmd，最后

ipconfig 即可查到。

6.要关闭windows防⽕墙

7.当时我还遇到了⼀个问题，就是当传递的信息复杂时，⽐如传递list型的⼀个⾃定义的类，会出现问题，当时我是重写了

ListAdapter类，如下所⽰：

package com.adapter;
