数据传送到后端（二）

先在myeclipse里建立上图文件，然后在TestServlet.java里面的doGet{}括号里面填入以下内容：

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//解决中文乱码
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
//在服务器端设置允许在其他域名下访问，及响应类型、响应头设置
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods","POST");
response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type");

PrintWriter out = response.getWriter();//创建相应前端的对象类

//接受前端传来的name,age值
String name;
String age;
name = request.getParameter("one");
age = request.getParameter("two");

//解决前端输入中文的乱码问题
String one = new String(name.getBytes("ISO-8859-1"),"UTF-8");
String two = new String(age.getBytes("ISO-8859-1"),"UTF-8");
System.out.println(one);
System.out.println(two);//控制台显示

out.print("this is a test");//网页上显示
out.flush();//把数据转化成数据流的形式发送到前端
out.close();//out是随便取的名字，关闭数据流

}
