短信验证码开头是cat什么意思？

短信验证码都是随机发送的，开头是这个字母的话也没有代表什么意思的，都是随机给你发送的一些东西。

不管我们在什么接口登录一般都需要通过用户名密码验证，其验证方式在对安全性要求比较高的应用上很容易被利用，造成损失。

如用户在购物时，登录成功后，需要要求用户绑定手机号码，这时会给用户的手机发一条验证短信，要求用户输入几个数字或者字母，这就是验证码。以后在网购付款时, 为确保安全, 网站后台都会通过。通俗的理解就是短信验证码是一种安全性很高的身份识别方式。

短信验证码现在广泛应用在网站会员手机验证、APP应用手机验证、订单通知、物流提醒等触发类短信应用。

扩展资料：

当用户在比如网站注册、软件登录等前端，进行用户信息和手机号码的填写操作之后，一旦点击了“获取验证码”选项；

这时网页或软件的系统后端上提前设置好的程序就会接收到前端发出的这个指令，自动生成一个随机验证码，通常大多数都会是一组由数字组成的字符，然后短信接口就会启动，利用服务器对收到的指令进行响应，发送出去这组验证码到用户手机上。

而用户则在前端将其输入后，后端系统就会通过算法对用户提交的验证码在后端系统储存的数据中进行比较，核对正确后就会验证成功，可以继续下一项操作了，反之则失败。

CATS - the original London version

- Jellicle Songs for Jellicle Cats

Are you blind when you're born Can you see in the dark

Can you look at a king Would you sit on his throne

Can you say of your bite that it's worse than your bark

Are you cock of the walk when you're walking alone

Because Jellicles are and Jellicles do

Jellicles do and Jellicles would

Jellicles would and Jellicles can

Jellicles can and Jellicles do

When you fall on your head, do you land on your feet

Are you tense when you sense there's a storm in the air

Can you find your way blind when you're lost in the street

Do you know how to go to the Heaviside Layer

Because Jellicles can and Jellicles do

Jellicles do and Jellicles can

Jellicles can and Jellicles do

Jellicles do and Jellicles can

Jellicles can and Jellicles do

Can you ride on a broomstick to places far distant

Familiar with candle, with book and with bell

Were you Whittington's friend The Pied Piper's assistant

Have you been an alumnus of heaven or hell

Jellicle songs for Jellicle cats

We can dive through the air like a flying trapeze

We can turn double somersaults, bounce on a tire

We can run up the wall, we can swing through the trees

We can balance on bars, we can walk on a wire

Jellicles can and Jellicles do

Jellicles can and Jellicles do

Jellicles can and Jellicles do

Jellicles can and Jellicles do
