XFire客户端编程实现方式和及AJAX调用方法

本文主要是介绍XFire客户端编程实现方式和及AJAX调用方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

 

1. 客户端拥有Web服务端的class字节码文件

条件：能拿到服务端提供的接口Class，包括启用代理模式的应用

private static void initWebServiceClient() {//Service srModel = new ObjectServiceFactory().create(TestDAOService.class);Service serviceModel = new ObjectServiceFactory().create(IHelloService.class);XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire());ResourceBundle rb = ResourceBundle.getBundle("com/sonyon/properties/config");//String endPoint = "http://80.80.100.186:80/xfire/services/IHelloService";String endPoint = rb.getString("service");boolean enableProxy = Boolean.valueOf(rb.getString("enableproxy")).booleanValue();String proxyAddress = rb.getString("proxyhost");String proxyPort = rb.getString("proxyport");try {//启用代理if(enableProxy){service = (IHelloService) factory.create(serviceModel,endPoint);//Client client = new Client(serviceModel,endPoint);Client client = Client.getInstance(service);//禁用默认代理Util类client.setProperty(CommonsHttpMessageSender.DISABLE_PROXY_UTILS,"true");client.setProperty(CommonsHttpMessageSender.DISABLE_KEEP_ALIVE,"true");//禁用100-continue协议client.setProperty(CommonsHttpMessageSender.DISABLE_EXPECT_CONTINUE,"true");client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_HOST,proxyAddress);client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PORT,proxyPort);//client.setProperty(HttpTransport.CHUNKING_ENABLED,"true");} else {//service = (IHelloService) factory.create(serviceModel,endPoint);service = (IHelloService) factory.create(serviceModel,endPoint);//Client client = new Client(serviceModel,endPoint);Client client =  Client.getInstance(service);//禁用默认代理Util类client.setProperty(CommonsHttpMessageSender.DISABLE_PROXY_UTILS,"true");client.setProperty(CommonsHttpMessageSender.DISABLE_KEEP_ALIVE,"true");//禁用100-continue协议client.setProperty(CommonsHttpMessageSender.DISABLE_EXPECT_CONTINUE,"true");//client.setProperty(HttpTransport.CHUNKING_ENABLED,"true");}/*URL testurl = new URL(testwsdl);HttpURLConnection httpConnection = (HttpURLConnection)testurl.openConnection();  httpConnection.setReadTimeout(20000);//设置http连接的读超时,单位是毫秒  httpConnection.connect();Client testClient = new Client(httpConnection.getInputStream(), null);//Client testClient = new Client(new URL(testwsdl));if(enableProxy){testClient.setProperty(CommonsHttpMessageSender.DISABLE_PROXY_UTILS,"true");testClient.setProperty(CommonsHttpMessageSender.HTTP_PROXY_HOST,"10.60.1.33");testClient.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PORT,"808");}*/String result = service.sayHi("test");logger.info("WebService测试程序返回字符串为:" + result);//Object[] results = testClient.invoke("getName",new Object[] {});if(result != null){logger.info("--------------WebService client Create and Test success----------------------------");} else {logger.warn("--------------WebService client Create success But Test failure---------------------");}} catch (Exception e) {logger.warn("WebService客户端连接服务器失败，请检查WebService服务器参数或网络连接!",e);}}// JSR181模式，注意这里Server端开发组需要向Client提供实现类，而不止于//接口，有点危险
Service srvcModel = new AnnotationServiceFactory().create(HelloServiceImpl.class);
XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String helloWorldURL = "http://localhost:8080/webservice/services/Hello";
Hello hello = (Hello) factory.create(srvcModel,helloWorldURL);
System.out.println(hello.sayHi("test"));

 

2、 动态模式，不生成字节码，直接调用

动态模式不需要服务端的class，不过性能和复杂对象映射等估计做得不会太好。

Client client = new Client(new URL("http://localhost:8080/webservice/services/Hellowsdl"));
Object[] results = client.invoke("sayHello", new Object[] { "Cao," });
System.out.println((String) results[0]);

3、 通过开发工具、根据WSDL生成Client Stub 

   注：来源于网络仅作参考

//简单参数的HelloClient client=new HelloClient();HelloPortType port =client.getHelloHttpPort();System.out.println(port.sayHello("hi!"));//参数复杂的MemberServiceClient client = new MemberServiceClient();MemberService memberService = client.getMemberServiceHttpPort();User user = new User();/*JAXBElement<String> name = new JAXBElement<String>(new QName("http://memberService", "username"), String.class, "smallnest");JAXBElement<String> password = new JAXBElement<String>(new QName("http://memberService", "password"), String.class, "123456");*/ObjectFactory objFac=new ObjectFactory();JAXBElement<String> name = objFac.createUserUsername("smallnest");JAXBElement<String> password = objFac.createUserPassword("123456");user.setUsername(name);user.setPassword(password);Member oneMember = new Member();JAXBElement<String> memeberName = new JAXBElement<String>(new QName("http://memberService", "name"), String.class, "迈克");JAXBElement<String> email= new JAXBElement<String(newQName("http://memberService","email"), String.class,"micro@micro.com");
oneMember.setName(memeberName);
oneMember.setEmail(email);
oneMember.setRank(6);
// 调用方法memberService.addMember(oneMember, user);

4、通过Ajax调用（js+XML）

(1、)

写一个页面，发送Ajax请求,请求的URL即服务的地址，请求方式是POST，另外，还需要设置请求头，以及手动构造请求体。

<head><title>通过ajax调用webservice服务</title>
<script>
var xhr;
function sendAjaxWS(){xhr = new ActiveXObject("Microsoft.XMLHTTP");                 //指定ws的请求地址var wsUrl = "http://192.168.1.108:5678/hello";//手动构造请求体var requestBody = '<soapenv:Envelope             xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" ' + ' 　　　　　　　　xmlns:q0="http://service.itcast.cn/" xmlns:xsd="http://www.w3.org/2001/XMLSchema "'+
' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">'+'<soapenv:Body><q0:sayHello><arg0>'+
document.getElementById("msg").value+'</arg0> <arg1>10</arg1> </q0:sayHello></soapenv:Body></soapenv:Envelope>';
//打开连接
xhr.open("POST",wsUrl,true);
//重新设置请求头
xhr.setRequestHeader("content-type","text/xml;charset=utf8");
//设置回调函数
xhr.onreadystatechange = _back;
//发送请求
xhr.send(requestBody);
}//定义回调函数function _back(){if(xhr.readyState == 4){if(xhr.status == 200){var ret = xhr.responseXML;//解析xmlvar eles = ret.getElementsByTagName("return")[0];alert(eles.text);}}}</script>
</head>
<body><input type="text" id="msg" /><input type="button" onclick="sendAjaxWS();" value="通过ajax调用webservice服务"/>
</body>

由于使用ajax – js调用web服务完成不同于使用java代码调用。所以，必须要对SOAP文件非常的了解。

一般使用ajax调用，应该是在已经获知了以下信息以后才去调用：

获知请求（request）的soap文本。

获知响应(response)的soap文本。

请求文件和响应文本格式，一般会随web服务的发布一同发布。

我们可以通过WSExplorer获取上面两段文本。

5、 通过URLConnection调用

         1，指定WebService服务的请求地址：

        String wsUrl = "http:// 124.205.244.130:5678/hello";

 　　  2，创建URL：URL url = new URL(wsUrl);

    　  3，建立连接，并将连接强转为Http连接

URLConnection conn = url.openConnection();

          HttpURLConnection con = (HttpURLConnection) conn;

   　   4，设置请求方式和请求头：

          con.setDoInput(true);                  //是否有入参

          con.setDoOutput(true);                //是否有出参

          con.setRequestMethod("POST");   // 设置请求方式

          con.setRequestProperty("content-type", "text/xml;charset=UTF-8");

  　　  5，// 手动构造请求体

               String requestBody = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" "

                         + " xmlns:q0=\"http://service.itcast.cn/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema \" "

                         + " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"

                         + "<soapenv:Body><q0:sayHello><arg0>lisi</arg0> <arg1>10</arg1> </q0:sayHello></soapenv:Body></soapenv:Envelope>";

　　　6，通过流的方式将请求体发送出去：

         //获得输出流

         OutputStream out = con.getOutputStream();

         out.write(requestBody.getBytes());

         out.close();

　　  7，服务端返回正常：

　　 int code = con.getResponseCode();

       if(code == 200){//服务端返回正常

         InputStream is = con.getInputStream();

         byte[] b = new byte[1024];

         StringBuffer sb = new StringBuffer();

         int len = 0;

         while((len = is.read(b)) != -1){

             String str = new String(b,0,len,"UTF-8");

             sb.append(str);

        }

        System.out.println(sb.toString());

        is.close();

       }

       con.disconnect();

}
