使用多种方式调用webservice服务

客户端调用webService有多种方式:

下面就以为http://www.webxml.com.cn/zh_cn/index.aspx上提供的, 查询手机号码为例, 阐述一下几种方式:

1: 使用wsimport, 或者是第三方框架的命令(比如cxf的wsdl2java)来自动生成代码

首先, 在命令行中运行:

wsimport -s . http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?wsdl

生成客户端代码, 并把生成的源码拷贝到项目中.

然后, 调用

public class PhoneCodeApp {public static void main(String[] args) {MobileCodeWS server = new MobileCodeWS();MobileCodeWSSoap soapPortType = server.getMobileCodeWSSoap();ArrayOfString result = soapPortType.getDatabaseInfo();for (String str : result.getString()) {System.out.println(str);}System.out.println(soapPortType.getMobileCodeInfo("15513061132", ""));}}

2: 利用jax-ws中的service类, 收到编写代码进行调用

首先, 也是需要命令来获得客户端代码, 但是仅仅需要soap调用接口.

然后编写代码:

public class ServiceCode {public static void main(String[] args) throws Exception {URL url = new URL("http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?wsdl");QName qName = new QName("http://WebXml.com.cn/", "MobileCodeWS");Service service = Service.create(url, qName);MobileCodeWSSoap portType = service.getPort(MobileCodeWSSoap.class);ArrayOfString string = portType.getDatabaseInfo();for (String str : string.getString()) {System.out.println(str);}System.out.println(portType.getMobileCodeInfo("15513061132", ""));}}

3: 使用urlconnection手动组装soap请求协议来调用服务
这种方式与上面2种不同, 是通过组装请求协议来调用的,因此不需要运行命令来获得代码

只需要编写代码即可.

public class PhoneCodeApp {public static void main(String[] args) throws Exception {// 建立连接URL url = new URL("http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx");HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoInput(true);connection.setDoOutput(true);connection.setRequestMethod("POST");connection.setRequestProperty("Content-Type", "text/xml;charset=utf-8");connection.setRequestProperty("SOAPAction","http://WebXml.com.cn/getDatabaseInfo");// 发送数据OutputStream outputStream = connection.getOutputStream();String str = "<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns: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><getDatabaseInfo xmlns=\"http://WebXml.com.cn/\" /></soap:Body></soap:Envelope>";outputStream.write(str.getBytes(Charset.forName("utf-8")));connection.connect();// 接受数据InputStream inputStream = connection.getInputStream();outputStream.close();inputStream.close();connection.disconnect();// 解析文档DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();DocumentBuilder builder = factory.newDocumentBuilder();Document document = builder.parse(inputStream);NodeList nodeList = document.getElementsByTagName("string");for (int i = 0; i < nodeList.getLength(); i++) {Node node = nodeList.item(i);System.out.println(node.getTextContent());}}}

4: 在页面上通过ajax来调用

这种方式本质同上面的方式一样,直接上代码

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title><script type="text/javascript">window.onload = function() {document.getElementById("btn").onclick = function() {var xmlHttpRequest = null;try {xmlHttpRequest = new XMLHttpRequest();} catch (e) {try {xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");} catch (e) {xmlHttpRequest = new ActiveXObject("Microsoft.XMLHTTP");}}var reqeustStr = '<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns: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><getDatabaseInfo xmlns=\"http://WebXml.com.cn/\" /></soap:Body></soap:Envelope>';xmlHttpRequest.open("POST", "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx", true);xmlHttpRequest.setRequestHeader("Content-Type", "text/xml;charset=utf-8");xmlHttpRequest.send(reqeustStr);xmlHttpRequest.onreadystatechange = function() {if(xmlHttpRequest.readyState == 4 && xmlHttpRequest.status == 200) {alert(xmlHttpRequest.responseText);}}}}</script></head><body><input type="button" value="发送请求" id="btn"/></body></html>
