TestInput的 servlet
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//这里是获取参数的
String data=request.getParameter("a");
InputStream stream=request.getInputStream();
InputStreamReader isr=new InputStreamReader(stream);
BufferedReader br=new BufferedReader(isr);
String str=br.readLine();
str=str.replace("a=", "");
System.out.println(str.getBytes()[0]+" "+str.getBytes()[1]+" "+str.getBytes()[2]);
System.out.println("王".getBytes("iso-8859-1")[0]);
System.out.println(str);
str=URLDecoder.decode(str,"utf-8");
System.out.println(str);
br.close();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
tomcat 的server.xml 关键部分
<Connector port="8086" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
useBodyEncodingForURI="true" URIEncoding="gbk"/>
因为程序 是用 json 传值的，传递到服务器的数据太多 数据不能放在url 中，只能放在send（）中
不要把数据封装成 xml 格式的
能解决把100分给他

要明白乱码的根因是由于编码格式不一致导致的，所以只要你所有的编码格式都统一应该不会出现乱码：
把所有的编码搞一致，都用UTF-8好了。
