Servlet學習筆記---重寫URl位址（編碼問題）

URLReWrite2.java

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 URLReWrite2 extends HttpServlet {

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		
		  response.setContentType("text/html;charset=UTF-8");
		  request.setCharacterEncoding("UTF-8");
		  
		PrintWriter pw=response.getWriter();
		pw.write(new String(request.getParameter("name").getBytes("ISO-8859-1"),"UTF-8"));
		pw.write(request.getParameter("age"));	
	}

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

}

URLWrite.java

package com.wanhao;

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 URLwrite extends HttpServlet {

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		  response.setContentType("text/html;charset=UTF-8");
		  request.setCharacterEncoding("UTF-8");
          String path=response.encodeURL("/Javaee/servlet/URLReWrite2?name=張三&age=16");
          PrintWriter out=response.getWriter();
		 out.write("<html>");
         out.write("<a href="+path+" target="_blank" rel="external nofollow" >here</a>");
         
		 out.write("</html>");
	}

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

}

說說實作中遇到的編碼問題：

在兩個Servlet中同時寫：

          response.setContentType("text/html;charset=UTF-8");

          request.setCharacterEncoding("UTF-8");

然後張三一直是亂碼，因為預設把浏覽器URL資訊的讀取是采用   iso-8859-1  格式的，是以必須要編碼轉換，

new String(request.getParameter("name").getBytes("ISO-8859-1"),"UTF-8")；便可
