Android WebService 使用小结
适合手机的WebService客户端SDK KSOAP2:
http://code.google.com/p/ksoap2-android/downloads/list
http://files.cnblogs.com/xiaobuild/KSOAP2_SDK.rar
将下载后的jar文件复制到工程的lib目录中（如果没有该目录，可以新建一个，当然，也可以放在其他的目录中）。并在工程中引用这个jar包
如何调用WebService
打开webServic链接，如http://macau.sanvio.net/ReadOrderWebService/wsReadOrder.asmx?op=GetNews

POST /ReadOrderWebService/wsReadOrder.asmx HTTP/1.1
Host: macau.sanvio.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: " http://tempuri.org/GetNews"
<?xmlversion="1.0"encoding="utf-8"?>
<soap:Envelopexmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd=" http://www.w3.org/2001/XMLSchema"xmlns:soap=" http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetNewsxmlns=" http://tempuri.org/">
<newsid>string</newsid>
</GetNews>
</soap:Body>
</soap:Envelope>\
|
根据该xml确定命名空间 ，调用方法， webServer地址，调用参数等

// 命名空间
privatestaticfinalString ServiceNameSpace =" http://tempuri.org/";
// webServer地址
privatestaticfinalString webServiceUrl =" http://macau.sanvio.net/ReadOrderWebService/wsReadOrder.asmx";
//webServer调用方法名
privatestaticfinalString GetNews ="GetNews";

// 实例化SoapObject对象
SoapObject request =newSoapObject(ServiceNameSpace, GetNews);
// 有参数的话,设置调用方法参数 request.addProperty("参数名称","参数值");
request.addProperty("newsid","0001");
// 获得序列化的Envelope 注册Envelope
SoapSerializationEnvelope envelope =newSoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet =true;
envelope.setOutputSoapObject(request);// envelope.bodyOut=request;
// HttpTransportSE传输对象
HttpTransportSE transport =newHttpTransportSE(webServiceUrl);
transport.debug =true;
// 调用
try{
transport.call(ServiceNameSpace + GetNews, envelope);
if(envelope.getResponse() !=null) {
System.out.println("Get Info is finisth!");
// System.out.println(envelope.bodyIn.toString());
// parseNews(envelope.bodyIn.toString());
//write(envelope.bodyIn.toString(), "001.txt");
//解析xml
parseNews(envelope);
}
}catch(IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch(XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
