servlet获取后台数据乱码处理( 二 ) _小知识

import javax.servlet.http.HttpServletResponse;
public class UserServlet exts HttpServlet {
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String sex = request.getParameter("sex");
String[] bobby = request.getParameterValues("bobby");

System.out.println("性别 :"+new String(sex.getBytes("ISO-8859-1"),"utf-8"));
for (int i = 1; i <= bobby.length; i++) {
System.out.println("快乐喜爱"+i+" :"+new String(bobby[i-1].getBytes("ISO-8859-1"),"utf-8"));
}
}
}

5第五步：利用post体例提交表单。
<form action="/servlet/userServlet.do" method="post">
快乐喜爱1：<input type="text" name="bobby"><br/>
快乐喜爱2：<input type="text" name="bobby"><br/>
快乐喜爱3：<input type="text" name="bobby"><br/>
快乐喜爱4：<input type="text" name="bobby"><br/>
性别：<input type="text" name="sex"><br/>
<input type="submit" value=https://vvvtt.com/article/"提交">
</form>

6第六部：传输之前利用编码。
1、js前端编码
encodeURI 方式编码
decodeURI 方式解码
2、java后台编码
import java.net.URLDecoder;
import java.net.URLEncoder;
//URLEncoder.encode("乱码","UTF8");编码
//URLDecoder.decode("乱码","UTF-8")解码
