httpClient访问webservice服务--带http头参数

httpClient访问webservice

之所以通过httpClient访问是因为有的webservice需要设置http header，比如利用soapUI工具时会设置http header，那么利用axis就没有办法设置http头（我没有找到），所以就需要利用httpClient进行webserivce访问，代码如下：
1， getData方法

private static String getData(String OperationCode, String param){        String returnVal = "" ;        StringBuilder xmlpara = new StringBuilder() ;        xmlpara.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:user=\"http://127.0.0.1:8080/UserAction\">") ;            xmlpara.append("<soapenv:Header/>") ;            xmlpara.append("<soapenv:Body>") ;                 xmlpara.append("<user:getUserDetailByName>") ;                    xmlpara.append("<user:param>" + param + "</user:param>") ;                xmlpara.append("</user:getUserDetailByName>") ;            xmlpara.append("</soapenv:Body>") ;         xmlpara.append("</soapenv:Envelope>") ;        String inputPara = xmlpara.toString() ;        HashMap<String,String> res = new HashMap<>();//          String endpoint = "http://124.205.248.2:8080/eSales/esales.asmx?WSDL";            String endpoint = "http://192.168.0.123:9090/esb.user";            PostMethod postMethod = new PostMethod(endpoint);            byte[] b;            try {                b = inputPara.getBytes("utf-8");                InputStream is = new ByteArrayInputStream(b,0,b.length);                RequestEntity re = new InputStreamRequestEntity(is,b.length,"application/soap+xml; charset=utf-8");                //把Soap请求数据添加到PostMethod中                postMethod.setRequestEntity(re);                postMethod.setRequestHeader("ClientId", "com.primeton.esb.hljsjzx.manage") ;//              postMethod.setRequestHeader("OperationCode", "com.primeton.esb.hljsjzx.Infrastructure.user.getUserDetailByName") ;                postMethod.setRequestHeader("OperationCode", OperationCode) ;                //生成一个HttpClient对象，并发出postMethod请求                HttpClient httpClient = new HttpClient();                int statusCode = httpClient.executeMethod(postMethod);                if(200==statusCode){                    String getServerData =  postMethod.getResponseBodyAsString();                    //System.out.println("----->"+getServerData);                    //获取返回值状态标识，标识为0：成功；非0：失败                    res.put("status", "0");                    //res.put("msg", getServerData);                    SAXReader sax = new SAXReader() ;                    Document doc = sax.read(new ByteArrayInputStream(getServerData.getBytes("utf-8"))) ;                    DefaultXPath xpath = new DefaultXPath("//ns1:out");                    xpath.setNamespaceURIs(Collections.singletonMap("ns1","http://127.0.0.1:8080/UserAction"));                     Element ele = (Element)xpath.selectSingleNode(doc) ;                    returnVal = ele.getText();                                  }            } catch (Exception e) {                res.put("status", "1");                res.put("msg", e.toString());                e.printStackTrace();            }            return returnVal;        }

1. 方法调用

public static void main(String[] args) {           String operationCode = "com.primeton.esb.hljsjzx.Infrastructure.user.getUserDetailByName" ;        Map map = getData(operationCode,xmlpara.toString()) ;        String val = "" ;        String status = (String)map.get("status");        if(status.equals("0")){            val = (String)map.get("msg") ;        }        SAXReader sax = new SAXReader() ;        try {            Document doc = sax.read(new ByteArrayInputStream(val.getBytes("utf-8"))) ;            DefaultXPath xpath = new DefaultXPath("//ns1:out");            xpath.setNamespaceURIs(Collections.singletonMap("ns1","http://127.0.0.1:8080/UserAction"));             Element ele = (Element)xpath.selectSingleNode(doc) ;            System.out.println(ele.getText());        } catch (UnsupportedEncodingException e) {            e.printStackTrace();        } catch (DocumentException e) {            e.printStackTrace();        }    }
