施用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

?1 package ?cn.vaga.testws;
?2
?3
?4 public ? 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

?1 package ?cn.vaga.testwsclient;
?2
?3 import ?java.util.List;
?4 import ?java.util.Vector;
?5
?6 import ?org.ksoap2.SoapEnvelope;
?7 import ?org.ksoap2.serialization.SoapObject;
?8 import ?org.ksoap2.serialization.SoapSerializationEnvelope;
?9 import ?org.ksoap2.transport.AndroidHttpTransport;
10
11 public ? 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 。
