Java实现开发短信验证码的完整教程

开发人员在开发网站注册、登录时经常需要用到短信验证码功能,下面小编就来详细介绍一下如何集成这个功能。

下面以使用榛子云短信为例:

1. 首先注册一个榛子云账号,注册地址: http://sms_developer.zhenzikj.com/zhenzisms_user/register.html

 

 

2. 注册完毕后从个人登录入口进入,地址:http://sms_developer.zhenzikj.com/zhenzisms_user/login.html

 

 

3. 进入"应用管理",默认会自动创建一个应用,获取AppId和AppSecret,这两个参数是用于开发的。

 

 

4. 下载SDK,我用的java开发,所以,下面的例子也以java为例,http://smsow.zhenzikj.com/doc/sdk.html

 

你可以直接下载jar包导入项目中,也可以使用maven

<dependency>
   <groupId>com.zhenzikj</groupId>
  <artifactId>zhenzisms</artifactId>
  <version>1.0.2</version>
</dependency>

 

5. 参考开发文档发送短信http://smsow.zhenzikj.com/doc/java_sdk_doc.html

 

AppId、AppSecret就是我们刚才从应用管理中获取的,apiUrl参数,由于我是个人账号,固定使用https://sms_developer.zhenzikj.com

注: 通过自己注册的都是个人账号,企业账号需要单独联系客服申请

使用很简单,初始化一个ZhenziSmsClient对象,然后调用send()方法发送短信

 

6. 一个完整的例子

一个完整的java发送短信验证码的完整实例,这是一个官方的使用demo,带有60秒倒计时功能。

效果:

 

源码

短信验证码实现流程
1、构造手机验证码,生成一个6位的随机数字串;
2、使用接口向短信平台发送手机号和验证码,然后短信平台再把验证码发送到制定手机号上
3、将手机号验证码、操作时间存入Session中,作为后面验证使用;
4、接收用户填写的验证码、手机号及其他注册数据;
5、对比提交的验证码与Session中的验证码是否一致,同时判断提交动作是否在有效期内;
6、验证码正确且在有效期内,请求通过,处理相应的业务。

 

我是java开发者,后端使用了springMvc,前端用的是jsp + jquery 

 

html

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html>

	function getBasePath(){
	    return '<%=basePath%>';
    }
</script>
</head>
<body>
   <form>
       <div class="row">
           <label>账号: </label><input name="userId">
       </div>
       <div class="row">
           <label>密码:</label><input name="password">
       </div>
       <div class="row">
           <label>手机号:</label><input name="mobile">
       </div>
       <div class="row">
           <label>验证码:</label>
           <input name="verifyCode">
           <button type="button" class="sendVerifyCode">获取短信验证码</button>
       </div>
       <div><button type="button" class="sub-btn">提交</button></div>
   </form>
</body>
</html>

  

js

$(function(){ 
	//短信验证码倒计时
	var countdownHandler = function(){
		var $button = $(".sendVerifyCode");
		var number = 60;
		var countdown = function(){
			if (number == 0) {
				$button.attr("disabled",false);
				$button.html("发送验证码");
	            number = 60;
	            return;
	        } else {
	        	$button.attr("disabled",true);
	        	$button.html(number + "秒 重新发送");
	        	number--;
	        }
			setTimeout(countdown,1000);
		}
		setTimeout(countdown,1000);
	}
	//发送短信验证码
	$(".sendVerifyCode").on("click", function(){
		var $mobile = $("input[name=mobile]");
		var data = {};
		data.mobile = $.trim($mobile.val());
		if(data.mobile == ''){
			alert('请输入手机号码');
			return;
		}
		var reg = /^1\d{10}$/;
		if(!reg.test(data.mobile)){
			alert('请输入合法的手机号码');
			return ;
		}
		$.ajax({
	        url: getBasePath()+"/sendSms",
	        async : true,
	        type: "post",
	        dataType: "text",
	        data: data,
	        success: function (data) {
	        	if(data == 'success'){
	        		countdownHandler();
	        		return ;
	        	}
	        	alert(data);
	        }
    	});
	})
	//提交
	$(".sub-btn").on("click", function(){
		var data = {};
		data.userId = $.trim($("input[name=userId]").val());
		data.password = $.trim($("input[name=password]").val());
		data.mobile = $.trim($("input[name=mobile]").val());
		data.verifyCode = $.trim($("input[name=verifyCode]").val());
		if(data.userId == ''){
			alert("请输入账号");
			return ;
		}
		if(data.password == ''){
			alert("请输入密码");
			return ;
		}
		if(data.mobile == ''){
			alert("请输入手机号");
			return ;
		}
		if(data.verifyCode == ''){
			alert("请输入验证码");
			return ;
		}
		$.ajax({
	        url: getBasePath()+"/register",
	        async : true,
	        type: "post",
	        dataType: "text",
	        data: data,
	        success: function (data) {
	        	if(data == 'success'){
	        		alert("注册成功");
	        		return ;
	        	}
	        	alert(data);
	        }
    	});
	})
});

这里省略了所有非空、手机号格式验证

流程:

1)填写手机号

2)获取手机号码,调用sendSms.html接口向手机发送短信验证码

3)用户手机接收到验证码后,将其填写到"验证码"文本框中

		doPost(request, response);
	}
 
	/**

	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		try {
			String mobile = request.getParameter("mobile");
			JSONObject json = null;
			//生成6位验证码
			String verifyCode = String.valueOf(new Random().nextInt(899999) + 100000);
			//发送短信
			ZhenziSmsClient client = new ZhenziSmsClient(apiUrl, appId, appSecret);
			String result = "{code:0}";//client.send(mobile, "您的验证码为:" + verifyCode + ",该码有效期为5分钟,该码只能使用一次!");
			json = JSONObject.parseObject(result);
			if(json.getIntValue("code") != 0){//发送短信失败
				renderData(response, "fail");
				return; 
			}
			//将验证码存到session中,同时存入创建时间
			//以json存放,这里使用的是阿里的fastjson
			HttpSession session = request.getSession();
			json = new JSONObject();
			json.put("mobile", mobile);
			json.put("verifyCode", verifyCode);
			json.put("createTime", System.currentTimeMillis());
			// 将认证码存入SESSION
			request.getSession().setAttribute("verifyCode", json);
			renderData(response, "success");
			return ;
		} catch (Exception e) {
			e.printStackTrace();
		}
		renderData(response, "fail");
	}
	
	protected void renderData(HttpServletResponse response, String data){
		try {
			response.setContentType("text/plain;charset=UTF-8");
			response.getWriter().write(data);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

  

json工具使用的是阿里的fastjson

appId和appSecret换成你自己的,注册之后可获得

		if(!json.getString("verifyCode").equals(verifyCode)){
			renderData(response, "验证码错误");
			return ;
		}
		if((System.currentTimeMillis() - json.getLong("createTime")) > 1000 * 60 * 5){
			renderData(response, "验证码已过期");
			return ;
		}
		//其他业务代码
		renderData(response, "success");
	}
	protected void renderData(HttpServletResponse response, String data){
		try {
			response.setContentType("text/plain;charset=UTF-8");

ok,大功告成
