博客讲述为网站图片投票制作自动投票机器人的过程。尝试三种方案，一是用js和ajax循环提交，后因网站改页面失败；二是用java编程提交模拟表单，未成功但理论可行；三是用greasemonkey结合ajax和图片解析服务器，理论可行。最后发现数据含明文校验码，成功刷票。

由于生活中需要对网站上的某张图片投票决定排名，无可避免地想起了做个自动投票机器人。

 

经过一天的尝试，三种方案：

（1）保存投票页面到本地，分析代码，直接用 js 和 ajax 循环提交，每次循环中间随机休眠几秒。一开始居然有效，不过好景不长，第二天就被网站改了页面，不能直接提交了。

            自动投票机器人一
        </title>
        <link rel="stylesheet" href="style.css" type="text/css"  media="screen">
        <script type="text/javascript">
					var counters=0;
					var xmlHttp;
					function S_xmlhttprequest(){
						if(window.ActiveXObject){
							xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
						} else if(window.XMLHttpRequest){
							xmlHttp = new XMLHttpRequest();
						}
					}
					function vote(){
							url =1;//id
							S_xmlhttprequest();
							xmlHttp.open("GET","http://www.xxxx.com/work/vote.php?id="+url+"&"+Math.random(),true);
							xmlHttp.send(null);
							alert('   投票成功！\n 谢谢您的支持！');
				    	counters++;
				    	document.getElementById("counter").innerText=counters;
				    	setTimeout("vote()",nextTime());
							
					}

			    function Workspace_OnLoad() {
			    	setTimeout("vote()",1000);
			    }
			    
			    function nextTime(){
			    	var vNum=1000;
						vNum = Math.random();
						vNum = Math.round(vNum*60000);
						return vNum;
			    }
        </script>
    </head>
    
    <body class="bgcolor" onload="Workspace_OnLoad();">
        <div align="center">
            <table class="bgjpg" align="center" border="0" cellpadding="0" cellspacing="0"
            width="100%">
                <tbody>
                    <tr height="10">
                        <td>
                        </td>
                    </tr>
                    <tr>
                        <td height="30">
                        </td>
                    </tr>
                </tbody>
            </table>
        </div>
    </body>

</html>

 

 

（2）发现需要提交表单到服务器，而不是直接发送GET请求，并且有 cookie 检查校验码，尝试用 java 编程，好象没成功，但理论上可行。

 

  • 获取校验码图片
  • tesseract OCR 解析校验码图片
  • 尝试提交模拟表单
  • 需要的 jar 包和 Tesseract OCR在网上搜。

（3）既然前面两种方法都没办法成功，尝试用第三种方法吧，比较复杂，但理论上一定可用（做出来后才发现，投票时间已经结束，无法验证）

 

  • greasemonkey
  • ajax 取得图片
  • 上传到图片解析服务器（需要搭建专门 OCR 解析服务器）
  • 从解析服务器返回解析后的校验码
  • 填充表单校验码，提交

第三种方法在理论上可行，但要注意获取图片后，要分析代码，或许其中不仅仅是图片数据，还包含了解 cookie 的写入，需要具体对应每一个投票网站具体分析。

***然而始料未及的是写了许多代码，在调试的时候才突然发现，取得检验图片的数据格式中，末尾包含了明文的4位校验码，NND不知是程序员留的后门还是写入 cookie 需要，忽然发现自己就很失败，被狗血了。

从而说明分析获得的数据是多么重要了。

 

天不负苦心人，投票服务器又开了，是时候上场了，一台机器一小时刷了上万票，有需要即可多开几台机器，要多少票都是如此简单，果然不是一般的爽。（不敢刷太多，树大招风（：）
