HttpClient4 Post XML数据

XMLApacheSOAPServlet 
阅读更多

最近项目中用到SOAP，要求客户端POST SOAP数据过去，整理一下自己写的东西。

 

POST XML一般有两种方法，一种是指定参数名，将该参数来进行XML数据的传输，这是最常用的一种方式。

 

这次我想说明的另外一种，直接将XML数据以流的方式写入请求。

 

Servlet POST方法中来接受传送过来的XML流：

 

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		response.setContentType("text/xml");  
		response.setCharacterEncoding("UTF-8");  
        PrintWriter out = response.getWriter();
        System.out.println("----------------------");  
        BufferedReader reader = new BufferedReader(new InputStreamReader(request.getInputStream(), "UTF-8"));
        String line = null;
        StringBuffer sb = new StringBuffer();
        while ((line = reader.readLine()) != null) {
        	sb.append(line).append("\r\n");
		}
        System.out.println(sb.toString());  
        System.out.println("----------------------");  
        out.print(sb.toString());  
		out.flush();
		out.close();
	}

 

 

Client端POST XML过去：

 

package com.javaeye.wangking717.util;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;

public class HttpConnectionUtil {

	private final static Log logger = LogFactory.getLog(HttpConnectionUtil.class);

	public static String postSOAP(String url, String soapContent) {

		HttpClient httpclient = null;
		HttpPost httpPost = null;
		BufferedReader reader = null;
		int i = 0;

		while (i < 4) {
			try {
				httpclient = new DefaultHttpClient();
				httpPost = new HttpPost(url);
				StringEntity myEntity = new StringEntity(soapContent, "UTF-8");
				httpPost.addHeader("Content-Type", "text/xml; charset=UTF-8");
				httpPost.setEntity(myEntity);
				HttpResponse response = httpclient.execute(httpPost);
				HttpEntity resEntity = response.getEntity();
				if (resEntity != null) {
					reader = new BufferedReader(new InputStreamReader(resEntity
							.getContent(), "UTF-8"));
					StringBuffer sb = new StringBuffer();
					String line = null;
					while ((line = reader.readLine()) != null) {
						sb.append(line);
						sb.append("\r\n");
					}
					return sb.toString();
				}

			} catch (Exception e) {
				i++;
				if (i == 4) {
					logger.error("not connect:" + url + "\n" + e.getMessage());
				}
			} finally {
				if (httpPost != null) {
					httpPost.abort();
				}
				if (reader != null) {
					try {
						reader.close();
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
				if (httpclient != null) {
					httpclient.getConnectionManager().shutdown();
				}
			}
		}
		return "none";
	}
	
	public static void main(String[] args) {
		String url = "http://localhost:8080/opgtest/servlet/MyTest";
		String soap = "<xml>\r\n"
						+ "<body>\r\n"
							+ "传递过来的内容\r\n" 
						+ "</body>\r\n"
					+ "</xml>";
		System.out.println(postSOAP(url, soap));

	}

}

 

OK,大功告成，很简单吧。
