HttpClient乱码问题

服务端Servlet代码：

package com.httpclient.test;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class HttpClientServlet extends HttpServlet {@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {this.doGet(req, resp);}@Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {req.setCharacterEncoding("UTF-8");resp.setCharacterEncoding("GBK");String username = req.getParameter("username");String password = req.getParameter("password");System.out.println(username);PrintWriter writer = resp.getWriter();writer.print(username + " = " + password);writer.close();}}

 

HttpClient客户端代码：

/* * To change this template, choose Tools | Templates * and open the template in the editor. */package com.chinapay.client;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import org.apache.commons.httpclient.HttpClient;import org.apache.commons.httpclient.HttpStatus;import org.apache.commons.httpclient.NameValuePair;import org.apache.commons.httpclient.methods.PostMethod;import org.apache.commons.httpclient.params.HttpMethodParams;public class HttpClientPost { public static void main(String[] args) throws IOException{ HttpClient client = new HttpClient(); client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8"); String url = "http://localhost:8080/httpclient/HttpClientServlet"; PostMethod postMethod = new PostMethod(url); NameValuePair[] data = { new NameValuePair("username", "你好") ,new NameValuePair("password", "wangtao") }; postMethod.setRequestBody(data); int resultCode = client.executeMethod(postMethod); if(resultCode != HttpStatus.SC_OK){ System.err.println("Method failed:" + postMethod.getStatusLine()); } InputStream responseBody = postMethod.getResponseBodyAsStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(responseBody,"GBK")); String tempBf = null; while((tempBf=reader.readLine()) != null){ System.out.println(tempBf); } }}

client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");和req.setCharacterEncoding("UTF-8");编码格式相同，BufferedReader reader = new BufferedReader(new InputStreamReader(responseBody,"GBK"));和resp.setCharacterEncoding("GBK");的编码格式相同。这样就可以解决乱码问题了。
