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

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

var countdownHandler = function(){

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({

alert("请输入验证码");
return ;

$.ajax({

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
