服务端Servlet代码：

[c-sharp] view plaincopyprint?

1. package com.httpclient.test;
2. import java.io.IOException;
3. import java.io.PrintWriter;
4. import javax.servlet.ServletException;
5. import javax.servlet.http.HttpServlet;
6. import javax.servlet.http.HttpServletRequest;
7. import javax.servlet.http.HttpServletResponse;
8. public class HttpClientServlet extends HttpServlet {
9. @Override
10. protected void doGet(HttpServletRequest req, HttpServletResponse resp)
11. throws ServletException, IOException {
12. this.doGet(req, resp);
13. }
14. @Override
15. protected void doPost(HttpServletRequest req, HttpServletResponse resp)
16. throws ServletException, IOException {
17. req.setCharacterEncoding("UTF-8");
18. resp.setCharacterEncoding("GBK");
19. String username = req.getParameter("username");
20. String password = req.getParameter("password");
21. System.out.println(username);
22. PrintWriter writer = resp.getWriter();
23. writer.print(username + " = " + password);
24. writer.close();
25. }
26. }

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 plaincopyprint?

1. /*
2. * To change this template, choose Tools | Templates
3. * and open the template in the editor.
4. */
5. package com.chinapay.client;
6. import java.io.BufferedReader;
7. import java.io.IOException;
8. import java.io.InputStream;
9. import java.io.InputStreamReader;
10. import org.apache.commons.httpclient.HttpClient;
11. import org.apache.commons.httpclient.HttpStatus;
12. import org.apache.commons.httpclient.NameValuePair;
13. import org.apache.commons.httpclient.methods.PostMethod;
14. import org.apache.commons.httpclient.params.HttpMethodParams;
15. public class HttpClientPost {
16. public static void main(String[] args) throws IOException{
17. HttpClient client = new HttpClient();
18. client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
19. String url = "http://localhost:8080/httpclient/HttpClientServlet";
20. PostMethod postMethod = new PostMethod(url);
21. NameValuePair[] data = {
22. new NameValuePair("username", "你好")
23. ,new NameValuePair("password", "wangtao") };
24. postMethod.setRequestBody(data);
25. int resultCode = client.executeMethod(postMethod);
26. if(resultCode != HttpStatus.SC_OK){
27. System.err.println("Method failed:" + postMethod.getStatusLine());
28. }
29. InputStream responseBody = postMethod.getResponseBodyAsStream();
30. BufferedReader reader = new BufferedReader(new InputStreamReader(responseBody,"GBK"));
31. String tempBf = null;
32. while((tempBf=reader.readLine()) != null){
33. System.out.println(tempBf);
34. }
35. }
36. }

/* * 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。
