servlet request获取请求行或者请求体中的paramerter,并解决编码问题

public class ParaServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

//--通知服务器以什么编码解码http请求中的实体内容,所以这行代码只能解决post提交的乱码

request.setCharacterEncoding("utf-8");

//对于get方法,要解决发送给服务器的乱码,只能手动解决

String username = request.getParameter("username");

username = new String(username.getBytes("iso8859-1"),"utf-8");

System.out.println(username);

//以enumeration 遍历所有parameter,并解决发送到服务器的编码问题

Enumeration<String> enumeration = request.getParameterNames();

while(enumeration.hasMoreElements()){

String name = enumeration.nextElement();

String value = new String(request.getParameter(name).getBytes("iso8859-1"),"utf-8");

System.out.println(name+" : "+value);

}

}

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

doGet(request, response);

}

}
