httpclient 调用webservice

使用HttpClient对Web Service调用

用到的jar包有：
    commons-codec-1.3.jar
    commons-httpclient-3.0.jar
    commons-logging-1.0.4.jar


具体流程大致这样：
       
        String soapRequestData = "<?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>" +
           " <qqCheckOnline xmlns=\"http://WebXml.com.cn/\">" +
          "    <qqCode>349104641</qqCode>" +
         "   </qqCheckOnline>" +
        "  </soap12:Body>" +
        "</soap12:Envelope>";
       
        System.out.println(soapRequestData);


    //PostMethod postMethod = new PostMethod("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl");
   
    PostMethod postMethod = new PostMethod("http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl");

   // 然后把Soap请求数据添加到PostMethod中


    byte[] b = soapRequestData.getBytes("utf-8");
    InputStream is = new ByteArrayInputStream(b,0,b.length);
    RequestEntity re = new InputStreamRequestEntity(is,b.length,"application/soap+xml; charset=utf-8");
    postMethod.setRequestEntity(re);
   
    //最后生成一个HttpClient对象，并发出postMethod请求

    HttpClient httpClient = new HttpClient();
    int statusCode = httpClient.executeMethod(postMethod);
    String soapResponseData =  postMethod.getResponseBodyAsString();
       
       
    System.out.print(soapResponseData);



动态构造调用串的话如下实现：


    private String tns;
    private String methodName;
    private String wsdlLocation;
    private String soapResponseData;

private int invoke(Map<String, String> patameterMap) throws Exception {
        PostMethod postMethod = new PostMethod(wsdlLocation);
        String soapRequestData = buildRequestData(patameterMap);

        byte[] bytes = soapRequestData.getBytes("utf-8");
        InputStream inputStream = new ByteArrayInputStream(bytes, 0,
                bytes.length);
        RequestEntity requestEntity = new InputStreamRequestEntity(inputStream,
                bytes.length, "application/soap+xml; charset=utf-8");
        postMethod.setRequestEntity(requestEntity);

        HttpClient httpClient = new HttpClient();
        int statusCode = httpClient.executeMethod(postMethod);
        soapResponseData = postMethod.getResponseBodyAsString();
        return statusCode;
    }

    private String buildRequestData(Map<String, String> patameterMap) {
        StringBuffer soapRequestData = new StringBuffer();
        soapRequestData.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        soapRequestData
                .append("<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\">");
        soapRequestData.append("<soap12:Body>");
        soapRequestData.append("<" + methodName + " xmlns=\"" + tns + "\">");
        Set<String> nameSet = patameterMap.keySet();
        for (String name : nameSet) {
            soapRequestData.append("<" + name + ">" + patameterMap.get(name)
                    + "</" + name + ">");
        }
        soapRequestData.append("</" + methodName + ">");
        soapRequestData.append("</soap12:Body>");
        soapRequestData.append("</soap12:Envelope>");

        return soapRequestData.toString();
    }
