使用ksoap2 for android 调用WebService

1，建立WebService服务器
??? 这里使用Apache的axis2来建立WebService，并使用RPC的方式。
??? (1) 首先下载Axis，然后将解压后的webapp下面的东东拷贝到Tomcat的webapp下面，目录为/webapp/axis。去掉一些不相干的部署文本，如果classes下面的东东。
?? 写server-config.wsdd文件，放置到axis的WEB-INF目录下面。具体如下

?1<?xml?version="1.0"?encoding="UTF-8"?>
?2<deployment?xmlns="http://xml.apache.org/axis/wsdd/"
?3????xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
?4
?5????<globalConfiguration>
?6????????<parameter?name="sendMultiRefs"?value="true"?/>
?7????????<parameter?name="disablePrettyXML"?value="true"?/>
?8????????<parameter?name="dotNetSoapEncFix"?value="true"?/>
?9????????<parameter?name="enableNamespacePrefixOptimization"?value="false"?/>
10????????<parameter?name="sendXMLDeclaration"?value="true"?/>
11????????<parameter?name="sendXsiTypes"?value="true"?/>
12????????<parameter?name="attachments.implementation"
13????????????value="org.apache.axis.attachments.AttachmentsImpl"?/>
14????</globalConfiguration>
15
16????<handler?type="java:org.apache.axis.handlers.http.URLMapper"
17????????name="URLMapper"?/>
18????<service?name="HelloService"?provider="java:RPC">
19????????<parameter?name="className"?value="cn.vaga.testws.HelloService"?/>
20????????<parameter?name="scope"?value="request"?/>
21????????<parameter?name="allowedMethods"?value="*"?/>
22????????
23????????<operation?name="sayHello"?qname="operNS:sayHello"?xmlns:operNS="http://testws.vaga.cn"?returnQName="sayHelloResult"?returnType="rtns:ListOfHello"?xmlns:rtns="http://testws.vaga.cn"?/>
24?
25????<typeMapping
26???????xmlns:ns="http://localhost:8080/TestWS/services/HelloService"
27???????qname="ns:ListOfHello"
28???????type="java:java.lang.String[]"
29???????serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
30???????deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
31???????encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
32?????/>????
33????????<messageReceiver
34????????????class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"?/>
35????????????
36
37????</service>
38????<transport?name="http">
39????????<requestFlow>
40????????????<handler?type="URLMapper"?/>
41????????</requestFlow>
42????</transport>
43</deployment>

?? (2) 写业务类HelloService.java

???1package?cn.vaga.testws;
?2
?3
?4public?class?HelloService{
?5????public?String[]?sayHello(){
?6????????return?new?String[]{"www","1232","12dd"};
?7????}
?8????
?9????public?String?sayHelloToPerson(String?name){
10?????????if(name?==?null?||?"".equals(name)){
11??????????????name?=?"nobody";
12?????????}
13?????????
14?????????return?"Hello?"?+?name;
15????}
16}

??? 然后将编译好的class文件放置到axis/WEB-INF/classes下面，注意包结构。启动Tomcat。
?? (3) 在浏览器中输入http://192.168.1.110:8080/TestWS/services/HelloService?wsdl，OK，如果出现了XML代码表示你成功了。

2、使用ksoap2的客户端
???? (1) 建立客户端类

?1package?cn.vaga.testwsclient;
?2
?3import?java.util.List;
?4import?java.util.Vector;
?5
?6import?org.ksoap2.SoapEnvelope;
?7import?org.ksoap2.serialization.SoapObject;
?8import?org.ksoap2.serialization.SoapSerializationEnvelope;
?9import?org.ksoap2.transport.AndroidHttpTransport;
10
11public?class?Client??{
12????private?static?final?String?NAMESPACE?=?"http://testws.vaga.cn";????
13????private?static?String?URL?=?"http://192.168.1.110:8080/TestWS/services/HelloService";
14????private?static?final?String?METHOD_NAME?=?"sayHello";
15????private?static?String?SOAP_ACTION?=?NAMESPACE?+?"/"?+?METHOD_NAME;?
16????public?static?String?getHello()?{
17????????try?{
18????????????SoapObject?rpc?=?new?SoapObject(NAMESPACE,?METHOD_NAME);
19???????????//?rpc.addProperty("theCityName",?cityName);
20
21????????????AndroidHttpTransport?ht?=?new?AndroidHttpTransport(URL);
22????????????ht.debug?=?true;
23
24????????????SoapSerializationEnvelope?envelope?=?new?SoapSerializationEnvelope(
25????????????????????SoapEnvelope.VER11);
26????????????
27????????????envelope.bodyOut?=?rpc;
28????????????envelope.dotNet?=?true;
29????????????envelope.setOutputSoapObject(rpc);
30
31????????????ht.call(SOAP_ACTION,?envelope);
32????????????
33//????????????debug(LOG_TAG,?"DUMP>>?"?+?ht.requestDump);
34//????????????debug(LOG_TAG,?"DUMP<<?"?+?ht.responseDump);
35
36????????????SoapObject?result?=?(SoapObject)?envelope.bodyIn;
37????????????Vector?vrct?=?(Vector)?result.getProperty("sayHelloResult");
38????????????for(int?i?=?0;?i?<?vrct.size();i++){
39????????????????System.out.println(?vrct.get(i));
40????????????}
41????????????String?ss?=?"";
42//???????????for(String?s?:?res){
43//???????????????ss?+=?s;
44//???????????}
45???????????
46???????????return?ss;
47????????}?catch?(Exception?e)?{
48????????????e.printStackTrace();
49????????}
50????????return?null;
51????}
52
53}
54
55

??? (2) 建好后，写一个main方法调用它就可以了。

最后，ksoap2非常的小，一百多K吧，使用它我们可以在Android程序中方便的调用WebService，而不用加载那些庞大的jar包。
最后给一个ksoap2 for android的下载地址。

注意：将扩展名改为jar即可！
