HttpClient乱码问题-优快云博客

服务端Servlet代码：

[c-sharp]view plaincopy 
   
 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 {  
   
     @Override  
     protected void doGet(HttpServletRequest req, HttpServletResponse resp)  
             throws ServletException, IOException {  
         this.doGet(req, resp);  
     }  
   
     @Override  
     protected 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：

[c-sharp]view plaincopy 
   
 /* 
  * 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。
