提交method教大家用HtmlUnit实现程序模拟页面表单提交
发一下牢骚和主题无关：
有时候大家做测试的时候需要验证web后台压力，如果让测试人员去一直的填写提交表单的话可能会让人吃不消，利用程序则可以很好的处理这一问题。
比如有一个web工程，其主页index.jsp:
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<form action="<%=path %>/LoginServ" method="post" name="loginForm" id="loginForm">
<table width="250" border="0">
<tr>
<td>账号：</td><td><input type="text" name="username" id="username"/></td>
</tr>
<tr>
<td>密码：</td><td><input type="password" name="pass" id="pass"/></td>
</tr>
<tr>
<td colspan=2><input type="submit" value="登岸" name="testlogin"/></td>
</tr>
</table>
</form>
</body>
</html>
其后台servlet为：
package com.test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class LoginServ extends HttpServlet {
/**
* Constructor of the object.
*/
public LoginServ() {
super();
}
/**
* Destruction of the servlet. <br>
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
/**
* The doGet method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
/**
* The doPost method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
String pass = request.getParameter("pass");
username = new String(username.getBytes("ISO-8859-1"),"utf-8");
System.out.println("用户登录，账号=【"+username+"】,密码=【"+pass+"】");
}
/**
* Initialization of the servlet. <br>
*
* @throws ServletException if an error occurs
*/
public void init() throws ServletException {
// Put your code here
}
}
将这个项目部署运行后，我们来编写测试代码，模拟表单提交数据：
package com.test;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlPasswordInput;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import com.gargoylesoftware.htmlunit.html.HtmlTextInput;
public class Test {
public static void submittingForm() throws Exception {
final WebClient webClient = new WebClient();
//1.获得某个待测页面
final HtmlPage page1 = webClient.getPage("http://localhost:8081/HtmlUnitTest");
//2.获得页面上的表单
final HtmlForm form = page1.getForms().get(0);
//3.获得页面上的各个元素
final HtmlSubmitInput button = form.getInputByName("testlogin");
final HtmlTextInput textField = form.getInputByName("username");
final HtmlPasswordInput pass= form.getInputByName("pass");
//4.给元素赋值
textField.setValueAttribute("我是张三");
pass.setValueAttribute("routon");
//5.提交
button.click();
}
public static void main(String[] args) {
try {
submittingForm();
} catch (Exception e) {
e.printStackTrace();
}
}
}
