package xyz.liut;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/servlet") // 请求接口
public class Test extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        // 设置编码和content-type
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/json");
        // response.setContentType("application/json;charset=utf-8");

        // 获取参数
        String param0 = request.getParameter("param0");
        String param1 = request.getParameter("param1");

        // 输出
        PrintWriter pw = response.getWriter();
        pw.println("req by " + request.getMethod());
        pw.println("req_ContentType " + request.getContentType());
        pw.println("resp_ContentType " + response.getContentType());
        pw.println();
        pw.println("param0 = " + param0);
        pw.println("param1 = " + param1);
        pw.close();
    }

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