C\#发布WebService接口

使用HTTPConnection直接Post参数进行调用

URL url = new URL(surl);
    			HttpURLConnection connection = (HttpURLConnection) url
    					.openConnection();
    			SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmssSSS");
    			connection.setDoOutput(true);
    			connection.setRequestMethod("POST");
    			connection.setDoInput(true);
    			connection.setRequestProperty("Content-Type",
    					"text/xml; charset=utf-8");
    			connection.setRequestProperty("SOAPAction",
    					"http://tempuri.org/AddMyToReadList");
    
    			OutputStreamWriter out = new OutputStreamWriter(
    					connection.getOutputStream(), "utf-8");
    			StringBuilder sb = new StringBuilder();
    sb.append("<MyToReadListInfo>");
    					sb.append("<SSIC_ID>" + info.getSsic_id() + "</SSIC_ID>");
    					sb.append("<URL><![CDATA[" + retURL + "]]></URL>");
    					sb.append("<OutID><![CDATA[" + strNow + "]]></OutID>");
    					sb.append("<Infor_Id><![CDATA[" + strNow.substring(8)
    							+ "]]></Infor_Id>");
    					sb.append("<Stru_ID></Stru_ID>");
    					sb.append("<Opertor>000000003</Opertor>");
    					sb.append("<Status>0</Status>");
    					sb.append("<Title><![CDATA[" + strtitle + "]]></Title>");
    					sb.append("</MyToReadListInfo>");
    StringBuilder header_sb = new StringBuilder();
    				StringBuilder footer_sb = new StringBuilder();
    				header_sb.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
    				header_sb
    						.append("<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/\">");
    				header_sb.append("<soap:Body>");
    				header_sb
    						.append("<AddMyToReadList xmlns=\"http://tempuri.org/\">");
    				header_sb.append("<AppKeyValue>");
    				header_sb.append("<AppID><![CDATA[" + getProperty("appid")
    						+ "]]></AppID>");
    				header_sb.append("<AppValue><![CDATA["
    						+ getProperty("appvalue") + "]]></AppValue>");
    				header_sb.append("</AppKeyValue>");
    				header_sb.append("<MyToReadListInfoList>");
    
    				footer_sb.append("</MyToReadListInfoList>");
    				footer_sb.append("</AddMyToReadList>");
    				footer_sb.append("</soap:Body>");
    				footer_sb.append("</soap:Envelope>");
    
    				out.write(header_sb.toString() + sb.toString() + footer_sb); // 直接post的进行调用！
    
    //解析返回的XML字串
    out.flush();
    				out.close();
    				connection.connect();
    
    				InputStream urlStream = connection.getInputStream();
    				BufferedReader bufferedReader = new BufferedReader(
    						new InputStreamReader(urlStream));
    				String ss = null;
    				String total = "";
    				while ((ss = bufferedReader.readLine()) != null) {
    					total += ss;
    				}
    
    				logger.info("接口返回结果");
    				logger.info(total);
    				bufferedReader.close();
    
    				Document document = DocumentHelper.parseText(total);
    				Node node = document
    						.selectSingleNode("/soap:Envelope/soap:Body/*[name()='AddMyToReadListResponse']/*[name()='AddMyToReadListResult']/*[name()='RetCode']");
    				String retCode = node.getText();
    
    				logger.info("retCode = " + retCode);

可以使用XPath来直接读取解析返回的字串，具体路径如果无法准确获知，可通过下面的方法获取节点路径。

public static void treeWalk(Document document) {
    		treeWalk(document.getRootElement());
    	}
    
    	public static void treeWalk(Element element) {
    		for (int i = 0, size = element.nodeCount(); i < size; i++) {
    			Node node = element.node(i);
    			System.out.println("Name = " + element.getName() + " Path = "
    					+ element.getPath());
    			if (node instanceof Element) {
    				treeWalk((Element) node);
    			} else {
    				// do something....
    			}
    		}
    	}
