1。后台利用 cxf 构建一个web service服务。

HelloWorld.java

/** *  */package com.alcor.jws.test;import javax.jws.WebMethod;import javax.jws.WebService;import org.apache.cxf.feature.Features;/** * @author 徐泽宇(roamer) *  *         2010-7-10 */@WebService@Features(features = "org.apache.cxf.feature.LoggingFeature")public interface HelloWorld {@WebMethod String sayHi(String text);@WebMethod boolean userLogon(String username,String userpasswd);}

HelloWorldImpl.java

/** *  */package com.alcor.jws.test;import org.apache.cxf.feature.Features;import org.apache.log4j.Logger;import javax.jws.WebMethod;import javax.jws.WebService;/** * @author 徐泽宇(roamer) * * 2010-7-10 */@WebService@Features(features = "org.apache.cxf.feature.LoggingFeature")public class HelloWorldImpl implements HelloWorld {/** * Logger for this class */private static final Logger logger = Logger.getLogger(HelloWorldImpl.class);@WebMethod     public String sayHi(String text) {if (logger.isDebugEnabled()) {logger.debug("sayHi(String) - start"); //$NON-NLS-1$}String returnString = "Hello,你好： " + text;if (logger.isDebugEnabled()) {logger.debug("返回内容："+returnString);logger.debug("sayHi(String) - end"); //$NON-NLS-1$}        return returnString;    }@WebMethodpublic boolean userLogon(String username ,String userpasswd){logger.debug("用户名是："+username+"口令是："+userpasswd);if (username.equalsIgnoreCase("admin")){return true;}else{return false;}}}

java 的web service 访问客户端

/** *  */package com.alcor.jws.test;import org.apache.cxf.interceptor.LoggingInInterceptor;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;/** * @author 徐泽宇(roamer) *  *         2010-7-10 */public class Client {private Client() {}public static void main(String args[]) throws Exception {/*第一种方法，通过配置文件来实现  beginApplicationContext ctx = new ClassPathXmlApplicationContext("META-INF/WebServiceClient.xml");HelloWorld client = (HelloWorld) ctx.getBean("client");String result = client.sayHi("Roamer");System.out.println(result);boolean logonResult = client.userLogon("roamer", "passwd");System.out.println(logonResult);    logonResult = client.userLogon("admin", "passwd");System.out.println(logonResult);*/JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setAddress("http://localhost:8080/SampleWebService/webservice/HelloWorld"); factory.setServiceClass(HelloWorld.class); factory.getInInterceptors().add(new LoggingInInterceptor()); HelloWorld helloWorld = (HelloWorld) factory.create(); boolean msg = helloWorld.userLogon("admin","World"); System.out.println(msg); }}

其中要注意的几点。

<ns1:userLogon xmlns:ns1=\"http://localhost:8080/SampleWebService/webservice/HelloWorld/\">"                             "<arg0>%@</arg0>"                             "<arg1>%@</arg1>"                             "</ns1:userLogon>"

中web service 中的 userLogon方法的调用要用ns1来引用。

传递的参数不能和 webservice的变量名来写。而只能写成 arg0 和 arg1 这种方式。我查阅其他网上资料，都是写成<username>和<userpasswd>这种element的形式。但是在我的这个演示中，如果写成这种方式。后台会无法获得传入的变量。而用arg0 这种方式是可以传入。我不清楚是否是和 java cxf的webservice搭建环境和版本有关。

注意:如果后台的WebService是.net开发的，调用的程序略有不同：

例如后台的ws服务链接是：http://10.100.111.231:9000/MobileService.asmx

那么访问这个url，会返回如下内容：

这个页面提示了SOAP 1.1 和 SOAP 1.2 的调用的内容

SOAP 1.1The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values. POST /MobileService.asmx HTTP/1.1Host: 10.100.111.231Content-Type: text/xml; charset=utf-8Content-Length: lengthSOAPAction: "http://tempuri.org/Logon"<?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>    <Logon xmlns="http://tempuri.org/">      <userName>string</userName>      <password>string</password>    </Logon>  </soap:Body></soap:Envelope>HTTP/1.1 200 OKContent-Type: text/xml; charset=utf-8Content-Length: length<?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>    <LogonResponse xmlns="http://tempuri.org/">      <LogonResult>string</LogonResult>    </LogonResponse>  </soap:Body></soap:Envelope>SOAP 1.2The following is a sample SOAP 1.2 request and response. The placeholders shown need to be replaced with actual values.POST /MobileService.asmx HTTP/1.1Host: 10.100.111.231Content-Type: application/soap+xml; charset=utf-8Content-Length: length<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">  <soap12:Body>    <Logon xmlns="http://tempuri.org/">      <userName>string</userName>      <password>string</password>    </Logon>  </soap12:Body></soap12:Envelope>HTTP/1.1 200 OKContent-Type: application/soap+xml; charset=utf-8Content-Length: length<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">  <soap12:Body>    <LogonResponse xmlns="http://tempuri.org/">      <LogonResult>string</LogonResult>    </LogonResponse>  </soap12:Body></soap12:Envelope>

那么，我们在objectiveC中代码应该写成

static NSString * wsURL = @"http://10.100.111.231:9000/MobileService.asmx";

   NSString *soapMessage = [NSString stringWithFormat:
                             @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                             "<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>\n"
                             "<Logon xmlns=\"http://tempuri.org/\">"
                             "<userName>%@</userName>"
                             "<password>%@</password>"
                             "</Logon>"
                             "</soap:Body>\n"
                             "</soap:Envelope>",self.userNameTextField.text,self.userPasswordTextField.text];

    NSLog(@"调用webserivce的字符串是:%@",soapMessage);
    //请求发送到的路径
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",wsURL]];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];

     //以下对请求信息添加属性前四句是必有的，
    [urlRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [urlRequest addValue:@"http://tempuri.org/Logon" forHTTPHeaderField:@"SOAPAction"];
    NSLog(@"SOAPAction is %@ ",@"http://tempuri.org/Logon");
    [urlRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];


    //请求
    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
    theConnection = nil;

注意红色的代码，这个http://tempurl.org/Logon 是要和 .net中的代码一致。否则无法访问。

这个字符串的内容可以从asmx返回帮助界面来获得。
