如何根据接口写一个客户端进行发单测试？

时间：2022-12-18 12:58:51

第一步，先写一个ｊｓｐ页面，定义ｊｓｐ将ｆｏｒｍ表单提交给SiglePaymentServlet

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>SR</title>
</head>
<body>
<H2>单笔代扣发单</H2>

<form action="TestServlet" method="post">
<input type="text" name="test1" /><br/>
<input type="text" name="test2" /><br/>
<input type="submit" value="提交" />
</form>
</body>
</html>

２第二步，创建ＴestServlet

package com.test;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

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

import net.sf.json.JSONObject;


/** * Servlet implementation class TestServlet */
@WebServlet("/TestServlet")
public class TestServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
       private String url=""; 
       private String merchId=""; 
       private String key=""; 



    /** * @see HttpServlet#HttpServlet() */
    public TestServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

    /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

    /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub


        String test1=request.getParameter("test1")  ;
        System.out.println(test1);
        Map<String, String> paraMap = new HashMap<String, String>();


        url=request.getParameter("url");
        merchId=request.getParameter("merchId");
        key=request.getParameter("key");

        paraMap.put("test1", request.getParameter("test1"));
        paraMap.put("test2", request.getParameter("test2"));

        JSONObject jsob = JSONObject.fromObject(paraMap);
        String content = jsob.toString();
        String res = HttpClientUtil.post(url, content,merchId,key);

        PrintWriter out = response.getWriter();
        out.print(res);





    }

}
