Android Call 调用WebService

android端与服务器交互 一般情况下,我们可以使用SOCKET,HTTP(GET,POST)等,我们也可以使用另外一种方式,webservice,
它是一种基于SAOP协议的远程调用标准,通过webservice可以将不同操作系统平台,不同语言,不同技术整合到一起。说白了就是一种中间件技术.
我们在android客户端中,有时需要一些库,比如XFire,Axis2,CXF等等来支持访问WebService,由于android sdk等并没有提供这些库,所以并不适合我们资源有限的android手机客户端,这里有KSOAP这个第三方的类库,可以帮助我们获取服务器端webService调用,KSOAP已经提供了基于android版本的jar包.

先下载KSOAP包:ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar包

然后新建一个android项目:并把下载的KSOAP包放在android项目的lib目录下:右键->build path->configure build path--选择Libraries,如图:

以下分为七个步骤来调用WebService方法:

第一:实例化SoapObject 对象,指定webService的命名空间(从相关WSDL文档中可以查看命名空间),以及调用方法名称。

publicfinalstatic String NAMESPACE = "http://tempuri.org/"; 

publicstatic String wsdl ="http://jinhesoft.com/Service1.asmx"; 

privatefinalstatic String defaultAddress ="jinhesoft.com"; 
privatefinalstatic String defaultPage = "service1.asmx"; 
publicfinalstatic String CONFIG_PATH = "/data/data/org.DigitalCM/DigitalCMWebserviceConfig.dat";

第二步:假设方法有参数的话,设置调用方法参数

request.addProperty("参数名称","参数值");

第三步:设置SOAP请求信息(参数部分为SOAP协议版本号,与你要调用的webService中版本号一致):

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( 
    SoapEnvelope.VER10); 
  envelope.setOutputSoapObject(request); 

  // envelope.bodyOut = request; 

第四步:构建传输对象,并指明WSDL文档URL:

HttpTransportSE ht = new HttpTransportSE(wsdl);

第五步:调用WebService(其中参数为1:命名空间+方法名称,2:Envelope对象):

ht.call(SOAP_ACTION, envelope);// 调用webservice(其中参数一SOAP_ACTION为命名空间+方法名,参数二为envelope) 

第六步:解析返回数据

resultObject = envelope.getResponse();

第7步:使用getResponse方法获得WebService方法的返回结果

原理和步骤过程了解后,我们下面结合具体项目实例给大家分享下,我们还是以之前的一篇文章: 登陆界面软件自动更新功能的实现http://blog.csdn.net/jindegegesun/article/details/7232779

为例进行,简化更改一个登陆过程。

1、新建一个登陆的布局界面

publicclass Main extends Activity {

    protectedvoid onCreate(Bundle savedInstanceState) {

    }
}

第四步:添加程序所用的权限:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cn.jindegegesun.activity"
    android:versionCode="1"
    android:versionName="1.0"><uses-sdk android:minSdkVersion="7"/><application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"><activity
            android:name=".DigitalCity"
            android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN"/><category android:name="android.intent.category.LAUNCHER"/></intent-filter></activity><activity
            android:label="@string/login_name"
            android:name="cn.jindegegesun.activity.Main"></activity></application><uses-permission android:name="android.permission.INTERNET"/></manifest>

注意:在第一个DigitalCity .activity的login()方法调用了webservice返回的数据,先贴出代码;

以上的红色字体部分就是具体调用webservice的具体步骤,最后一步,也就是第六步将会提供结果给调用webservice的方法,然后login()方法将通过
result = WSUtil.getSoapObjectByCallingWS(
WebServiceConfig.NAMESPACE, "login", params,
WebServiceConfig.wsdl);

得到第六步返回的结果。

当返回的结果与登陆界面输入的帐号和密码匹配后,登陆就成功了。

当然与服务器交互,这里还需要写接口,关键是其中的sql语句,我是在visual studio 2008上用c#写的一个login接口,如下:

    [WebMethod(Description = "Android 接口: 登陆 userName 用户名 userPwd 用户密码")]  
            public DataSet login(string userName, string userPwd)  
            {  
                DataSet ds = null;  
      
                string strSql = string.Format("select userid, username, password, deptid, realname, tel, email, usermemo, starttime, endtime, mapid, dwid, zw, deptname, purviewmid, dwmc from V_USERS t where t.username = '{0}' and t.password='{1}'", userName, userPwd);  
                try  
                {  
                    RetStrSql(strSql);  
                    ds = RetDataSet();  
                    return ds;  
                }  
                catch (Exception ex)  
                {  
                    //throw new Exception(ex.Message);  returnnull;  
      
                }  
            }
