今天就跟大家聊聊有關(guān)Android中怎么與服務(wù)器端數(shù)據(jù)進(jìn)行交互,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結(jié)了以下內(nèi)容,希望大家根據(jù)這篇文章可以有所收獲。
在保亭黎族等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務(wù)理念,為客戶提供成都網(wǎng)站建設(shè)、成都做網(wǎng)站 網(wǎng)站設(shè)計(jì)制作按需求定制制作,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),成都品牌網(wǎng)站建設(shè),營(yíng)銷型網(wǎng)站建設(shè),外貿(mào)網(wǎng)站建設(shè),保亭黎族網(wǎng)站建設(shè)費(fèi)用合理。
?首先下載KSOAP包:
ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar
然后新建android項(xiàng)目:并把下載的KSOAP包放在android項(xiàng)目的lib目錄下:右鍵->build path->configure build path--選擇Libraries,如圖:
以下分為七個(gè)步驟來(lái)調(diào)用WebService方法:
1、實(shí)例化SoapObject 對(duì)象,指定webService的命名空間(從相關(guān)WSDL文檔中可以查看命名空間),以及調(diào)用方法名稱。如:
//命名空間 private static final String serviceNameSpace="http://WebXml.com.cn/"; //調(diào)用方法(獲得支持的城市) private static final String getSupportCity="getSupportCity"; //實(shí)例化SoapObject對(duì)象 SoapObject request=new SoapObject(serviceNameSpace, getSupportCity);
2、假設(shè)方法有參數(shù)的話,設(shè)置調(diào)用方法參數(shù)
request.addProperty("參數(shù)名稱","參數(shù)值");
3、設(shè)置SOAP請(qǐng)求信息(參數(shù)部分為SOAP協(xié)議版本號(hào),與你要調(diào)用的webService中版本號(hào)一致):
//獲得序列化的Envelope SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.bodyOut=request;
4、注冊(cè)Envelope,
?(new MarshalBase64()).register(envelope);
5、構(gòu)建傳輸對(duì)象,并指明WSDL文檔URL:
//請(qǐng)求URL private static final String serviceURL="http://www.webxml.com.cn/webservices/weatherwebservice.asmx"; //Android傳輸對(duì)象 AndroidHttpTransport transport=new AndroidHttpTransport(serviceURL); transport.debug=true;
6、調(diào)用WebService(其中參數(shù)為1:命名空間+方法名稱,2:Envelope對(duì)象):
transport.call(serviceNameSpace+getWeatherbyCityName, envelope);
7、解析返回?cái)?shù)據(jù):
if(envelope.getResponse()!=null){ return parse(envelope.bodyIn.toString()); } /************** * 解析XML * @param str * @return */ private static List<String> parse(String str){ String temp; List<String> list=new ArrayList<String>(); if(str!=null && str.length()>0){ int start=str.indexOf("string"); int end=str.lastIndexOf(";"); temp=str.substring(start, end-3); String []test=temp.split(";"); for(int i=0;i<test.length;i++){ if(i==0){ temp=test[i].substring(7); }else{ temp=test[i].substring(8); } int index=temp.indexOf(","); list.add(temp.substring(0, index)); } } return list; }
這樣就成功啦。那么現(xiàn)在我們就來(lái)測(cè)試下吧,這里有個(gè)地址提供webService天氣預(yù)報(bào)的服務(wù)的,我這里只提供獲取城市列表:
//命名空間 private static final String serviceNameSpace="http://WebXml.com.cn/"; //請(qǐng)求URL private static final String serviceURL="http://www.webxml.com.cn/webservices/weatherwebservice.asmx"; //調(diào)用方法(獲得支持的城市) private static final String getSupportCity="getSupportCity"; //調(diào)用城市的方法(需要帶參數(shù)) private static final String getWeatherbyCityName="getWeatherbyCityName"; //調(diào)用省或者直轄市的方法(獲得支持的省份或直轄市) private static final String getSupportProvince="getSupportProvince";
我們選擇獲取國(guó)內(nèi)外主要城市或者省份的方法吧:getSupportProvice,然后調(diào)用,你會(huì)發(fā)現(xiàn)瀏覽器返回給我們的是xml文檔:
<?xml version="1.0" encoding="utf-8" ?> <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://WebXml.com.cn/"> <string>直轄市</string> <string>特別行政區(qū)</string> <string>黑龍江</string> <string>吉林</string> <string>遼寧</string> <string>內(nèi)蒙古</string> <string>河北</string> <string>河南</string> <string>山東</string> <string>山西</string> <string>江蘇</string> <string>安徽</string> <string>陜西</string> <string>寧夏</string> <string>甘肅</string> <string>青海</string> <string>湖北</string> <string>湖南</string> <string>浙江</string> <string>江西</string> <string>福建</string> <string>貴州</string> <string>四川</string> <string>廣東</string> <string>廣西</string> <string>云南</string> <string>海南</string> <string>新疆</string> <string>西藏</string> <string>臺(tái)灣</string> <string>亞洲</string> <string>歐洲</string> <string>非洲</string> <string>北美洲</string> <string>南美洲</string> <string>大洋洲</string> </ArrayOfString>
我們可以用 listview來(lái)顯示:
那么下面我將給出全部代碼:
public class WebServiceHelper { //WSDL文檔中的命名空間 private static final String targetNameSpace="http://WebXml.com.cn/"; //WSDL文檔中的URL private static final String WSDL="http://webservice.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl";

//根據(jù)城市或地區(qū)名稱查詢獲得未來(lái)三天內(nèi)天氣情況、現(xiàn)在的天氣實(shí)況、天氣和生活指數(shù) private static final String getWeatherbyCityName="getWeatherbyCityName"; /******** * 獲得州,國(guó)內(nèi)外省份和城市信息 * @return */ public List<String> getProvince(){ List<String> provinces=new ArrayList<String>(); String str=""; SoapObject soapObject=new SoapObject(targetNameSpace,getSupportProvince); //request.addProperty("參數(shù)", "參數(shù)值");調(diào)用的方法參數(shù)與參數(shù)值(根據(jù)具體需要可選可不選) SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet=true; envelope.setOutputSoapObject(soapObject);//envelope.bodyOut=request; AndroidHttpTransport httpTranstation=new AndroidHttpTransport(WSDL); //或者HttpTransportSE httpTranstation=new HttpTransportSE(WSDL); try { httpTranstation.call(targetNameSpace+getSupportProvince, envelope); SoapObject result=(SoapObject)envelope.getResponse(); //下面對(duì)結(jié)果進(jìn)行解析,結(jié)構(gòu)類似json對(duì)象 //str=(String) result.getProperty(6).toString();

SoapObject soapObject=new SoapObject(targetNameSpace,getWeatherbyCityName); soapObject.addProperty("theCityName",city);//調(diào)用的方法參數(shù)與參數(shù)值(根據(jù)具體需要可選可不選) SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
