分享一個完整的java發送短信驗證碼的完整實例，這是一個官方的使用demo，帶有60秒倒計時功能。
效果:
我使用的是榛子云短信平臺, 官網地址:http://smsow.zhenzikj.com
我是java開發者，後端使用了springMvc，前端用的是jsp + jquery

短信驗證碼實現流程
1、構造手機驗證碼，生成一個6位的隨機數字串；
2、使用接口向短信平臺發送手機號和驗證碼，然後短信平臺再把驗證碼發送到制定手機號上
3、將手機號驗證碼、操作時間存入Session中，作爲後面驗證使用；
4、接收用戶填寫的驗證碼、手機號及其他註冊數據；
5、對比提交的驗證碼與Session中的驗證碼是否一致，同時判斷提交動作是否在有效期內；
6、驗證碼正確且在有效期內，請求通過，處理相應的業務。

$(function(){
//短信驗證碼倒計時
var countdownHandler = function(){
var $button = $(".sendVerifyCode");
var number = 60;
var countdown = function(){
if (number == 0) {
$button.attr("disabled",false);
$button.html("發送驗證碼");
number = 60;
return;
} else {
$button.attr("disabled",true);
$button.html(number + "秒 重新發送");
number--;
}
setTimeout(countdown,1000);
}
setTimeout(countdown,1000);
}
//發送短信驗證碼
$(".sendVerifyCode").on("click", function(){
var $mobile = $("input[name=mobile]");
var data = {};
data.mobile = $.trim($mobile.val());
if(data.mobile == ''){
alert('請輸入手機號碼');
return;
}
var reg = /^1\d{10}$/;
if(!reg.test(data.mobile)){
alert('請輸入合法的手機號碼');
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("請輸入賬號");
return ;
}
if(data.password == ''){
alert("請輸入密碼");
return ;
}
if(data.mobile == ''){
alert("請輸入手機號");
return ;
}
if(data.verifyCode == ''){
alert("請輸入驗證碼");
return ;
}
$.ajax({
url: getBasePath()+"/register",
async : true,
type: "post",
dataType: "text",
data: data,
success: function (data) {
if(data == 'success'){
alert("註冊成功");
return ;
}
alert(data);
}
});
})
});這裏省略了所有非空、手機號格式驗證
流程：
1)填寫手機號
2)獲取手機號碼，調用sendSms.html接口向手機發送短信驗證碼
3)用戶手機接收到驗證碼後，將其填寫到"驗證碼"文本框中
