为了防止,页面向数据库暴力注册入力,用户登录暴力破解,所以加入验证码,验证码无法被软件获取上边的内容(加入算数计算,更加安全),所以在现在技术,暂时安全。

先看效果图:

第一次加载比较慢,防止无法加载验证码显示,后台获取准备好的默认正在加载图片(静态图片),后台图片获取好后,替代。


验证码效果图:

              

后台Java图片实现类VerificationCodeTool:

服务器,启动的时候,调用一次,生成默认图片到服务器“/servertempdictory/fileicon/”目录下:

              //create default verification code
              String  fileIconDictory = serverPath+"\\servertempdictory\\fileicon";
               imageTool.creatDefaultVerificationCode(fileIconDictory);
生成动态验证码,并保存值到session中(此处有登录和注册的分路,这个读者可忽略,走一条既可):

 /**
     * creat verification code
     * */
    public void verificationcode(){
      //response
      HttpServletResponse response = ServletActionContext.getResponse();
      //request
      HttpServletRequest request = ServletActionContext.getRequest();
      //verification code demander
      String vCdemander = request.getParameter("vcdemander");
      try{

	    response.setDateHeader("Expires", 0);
	    // Set the output stream content format as image format
	    response.setContentType("image/jpeg");
	    //session

	} catch (Exception e) {

	}
  }
用struts2实现,所以配置文件struts.xml:

	<!-- Set whether to support dynamic method calls, true to support, false does not support. -->
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<!-- The suffix specified request -->
	<constant name="struts.action.extension" value="do,go,tsXs,action"></constant>
	<!-- user operation [first login server,server initialize]-->
	<package name="user" namespace="/fileshare" extends="struts-default">
		<!-- user operate ; The wildcard method call-->
		<action name="user*" class="com.tsXs.fileshare.controller.UserController" method="{1}">
			<result name="success">/view/common/message.jsp</result>
			<result name="error">/view/userLogin.jsp</result>
		</action>
	</package>

页面jsp显示代码:

<tr>
  <td width="100">
    <span class="hint">*[验证码]:只能输入数字和负号"-"</span>
  </td>
</tr>
<tr>
  <td width="100">
    <label for="userRegPassWord">验证码</label>
    	  <input type="text" id="verificationcodereg" name="verificationcodereg" tabindex="3" maxlength="3" class="t_input" value="" style="ime-mode:disabled;"  onblur="checkuserverificationcode(this);" onkeypress="return (/[\d-]/.test(String.fromCharCode(event.keyCode)));"  />
    	 <span id="usvcmsg"></span>
    	<input type="hidden" id="verificationcoderegflag" value="" />
  </td>
</tr>
<tr>
  <td width="140">
    <div id="refreshvc">
    <span onclick="refreshvc();" style="padding-left: 49px;cursor: pointer;"><img id="verificationcodeimg" src="${pageContext.request.contextPath}/servertempdictory/fileicon/defaultverificationcode.jpeg" />
    <span style="height: 30px;width: 16px;padding-left: 4px;"><img src="image/refreshvc.png" /></span>
    <span style="font-size: 12px;color:#2c629e; width: 20px;">换一张</span>
    </span>
    </div>
  </td>
</tr>

在js中用正则,保证只能输入,最多3位,可以在数字前输入一个"-",即onkeypress保证只能输入数字和"-":

	var userverificationcoderegex = /^(-{0,1}\d+){1,3}$/;
	if(userverificationcoderegex.test(userverificationcode)){.....
jsp图片效果:


js动态刷新验证码:

$(document).ready(function(){
	//load verificatino code
	refreshvc();
});
//refresh verification code
function refreshvc(){
	var path = $("#contextPath").val();
	var refreshvcurl =path+"/fileshare/userverificationcode.tsXs?vcdemander=userregister&time="+new Date();
	$("#verificationcodeimg").attr("src",refreshvcurl);
}
