我有一个网络服务，我正在尝试为其构建客户端。

我有以下 wsdl:

http://www.cmicdataservices.com/datacenter/service.asmx?wsdl

它需要身份验证。查看 WSDL 描述，我没有看到任何方法将身份验证对象、用户名和密码作为参数。我使用 Netbeans 为 WSDL 生成了 jax-ws 源。然而，我不知道在那之后该怎么做。

使用 soapui 我可以连接到网络服务并运行所有方法。但再一次，我想将其构建到一个无需我交互即可运行的客户端。

我的问题在于弄清楚如何使用此生成的代码，netbeans.tv 似乎有一个视频(netbeans soapui 插件视频 2)，此后丢失了。有谁知道任何教程或知道如何使用此生成的代码访问 Web 服务的任何示例？

所以我有一个方法 CheckifAuthorized()

在 soapui 中运行我得到以下 xml

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:cmic="http://www.cmicdataservices.com/">
   <soap:Header>
      <cmic:Authentication>
         <!--Optional:-->
         <cmic:UserName>username</cmic:UserName>
         <!--Optional:-->
         <cmic:Password>password</cmic:Password>
      </cmic:Authentication>
   </soap:Header>
   <soap:Body>
      <cmic:CheckIfAuthorized/>
   </soap:Body>
</soap:Envelope>

然后我可以在 soap ui 中运行该请求并返回身份验证成功的响应。

使用 netbeans 和 soapui 生成的 jax-ws 代码，我有以下内容:

package javaapplication7;

/**
 *
 * @author grant
 */
public class Main {

    public static void main(String[] args) {

        Boolean result = checkIfAuthorized();
        System.out.println("The result is: " + result);
    }

    private static boolean checkIfAuthorized() {
        javaapplication7.CMICDatacenterService service = new javaapplication7.CMICDatacenterService();
        javaapplication7.CMICDatacenterServiceSoap port = service.getCMICDatacenterServiceSoap();
        return port.checkIfAuthorized();
    }
}

这将失败并出现以下错误

run:
Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Server was unable to process request. ---> Object reference not set to an instance of an object.
        at com.sun.xml.internal.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:178)

        at javaapplication7.Main.checkIfAuthorized(Main.java:24)
        at javaapplication7.Main.main(Main.java:17)
Java Result: 1

这与我在尝试使用 python 进行服务时遇到的问题相同。从那以后，我选择了使用 Java，因为我觉得我在解析 xml 和创建对象时可能会有更快的周转时间，因为我已经为此创建了实体。

谢谢。

我不想回答这个问题，因为我仍然想弄清楚我能在这里做什么，但我最终还是手写了以下请求。现在我可以将它转换成一个 xml 对象并按照我的方式进行，但我想 soapui 使所有这一切变得更加容易。我真正不明白的是如何使用soapui构建这个请求并将其合并到我的项目中:

public class Main {

    public final static String DEFAULT_SERVER =
            "http://www.cmicdataservices.com/datacenter/service.asmx";
    public final static String SOAP_ACTION =
            "http://www.cmicdataservices.com/CheckIfAuthorized";

     public static void main(String[] args) {
         String server = DEFAULT_SERVER;
         String UserName = "Username";
         String Password="Password";


     try{
             URL url = new URL(server);
             HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "application/soap+xml; charset=utf-8");
            connection.setRequestProperty("Host", "www.cmicdataservices.com");
            OutputStream out = connection.getOutputStream();
            Writer wout = new OutputStreamWriter(out);
            // Uncomment the following and comment out the previous two lines to see your xml
            //BufferedWriter wout = new BufferedWriter(new FileWriter("/tmp/testXML.xml"));

            //Start writing soap request - Envelope
            wout.write("<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n");
            wout.write("<soap12:Envelope ");
            wout.write("xmlns:xsi=");
            wout.write("'http://www.w3.org/2001/XMLSchema-instance' ");
            wout.write("xmlns:xsd=");
            wout.write("'http://www.w3.org/2001/XMLSchema' ");
            wout.write("xmlns:soap12=");
            wout.write("'http://www.w3.org/2003/05/soap-envelope'>\r\n");

            //Soap request header start
            wout.write("<soap12:Header>\r\n");

            //Start writing soap request - Authentication
            wout.write("<Authentication xmlns=");
            wout.write("'http://www.cmicdataservices.com/'>\r\n");
            wout.write("<UserName>" + UserName + "</UserName>\r\n");
            wout.write("<Password>" + Password + "</Password>\r\n");
            // End Authentication
            wout.write("</Authentication>\r\n");

            //End the header
            wout.write("</soap12:Header>\r\n");

            //Start writing the body
            wout.write("<soap12:Body>");
            wout.write("<GetCurrentDataVer1 xmlns=");
            wout.write("'http://www.cmicdataservices.com/' />\r\n");
            // End the Body
            wout.write("</soap12:Body>\r\n");

            // End the Envelope
            wout.write("</soap12:Envelope>\r\n");

            wout.flush();
            wout.close();


            //BufferedWriter fout = new BufferedWriter(new FileWriter("/tmp/testXMLResponse.xml"));
            InputStream in = connection.getInputStream();
            createFile(in, "/tmp/testXMLResponse.xml");
     }
     catch (IOException e) {
         System.err.println(e);
     }
     }

     public static void createFile(InputStream io, String fileName) throws IOException {
         FileOutputStream fout = new FileOutputStream(fileName);
         byte[] buf = new byte[256];
         int read = 0;
         while ((read = io.read(buf)) != -1){
             fout.write(buf, 0, read);
         }
     }

最佳答案

您的代码存在的问题是 SOAP header 中缺少 Authentication 元素。查看 WSDL，它应该始终存在:

<wsdl:operation name="CheckIfAuthorized">
    <soap:operation soapAction="http://www.cmicdataservices.com/CheckIfAuthorized" style="document"/>
    <wsdl:input>
        <soap:body use="literal"/>
        <soap:header message="tns:CheckIfAuthorizedAuthentication" part="Authentication" use="literal"/>
    </wsdl:input>
    <wsdl:output>
        <soap:body use="literal"/>
    </wsdl:output>
</wsdl:operation>

当 CheckIfAuthorized 请求中没有 Authentication 元素时，您的服务器因不正确的 XML 而失败并出现异常。这里有一个 Python 的示例客户端来演示解决问题的思路，我认为你将它转换为 Java 不是问题。

from suds.client import Client

client = Client("http://www.cmicdataservices.com/datacenter/service.asmx?wsdl")
auth = client.factory.create('Authentication')
auth.UserName = "username"
auth.Password = "password"
client.set_options(soapheaders=auth)
client.service.CheckIfAuthorized()
