短信验证码注册登录就是验证用户提交的手机验证码，如果验证码验证错误，就提示“验证码错误”，如果验证正确，那就进入到注册成功的页面。
这几天一直在研究JavaScript实现短信验证码注册登录的方法，主要是因为项目需求（现在好像几乎所有的项目都需要验证码注册登录），整理了三种对接方法，可供大家学习和参考：
Fetch方法
`var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
var urlencoded = new URLSearchParams();
urlencoded.append("appId", "41KYR0EB**");
urlencoded.append("appKey", "IIWCKKSR7NOQ**");
urlencoded.append("phone", "1561894**");
urlencoded.append("templateId", "1043");
urlencoded.append("variables", "1234");
var requestOptions = {
method: 'POST',
headers: myHeaders,
body: urlencoded,
redirect: 'follow'
};
fetch("https://vip.veesing.com/smsApi/verifyCode", requestOptions)
.then(response => response.text())
.then(result => console.log(result))
.catch(error => console.log('error', error));`
jQuery方法
`var settings = {
"url": "https://vip.veesing.com/smsApi/verifyCode",
"method": "POST",
"timeout": 0,
"headers": {
"Content-Type": "application/x-www-form-urlencoded;charset=utf-8"},
"data": {
"appId": "41KYR0EB****",
"appKey": "IIWCKKSR7NOQ****",
"phone": "1561894****",
"templateId": "1043",
"variables": "1234"}
};
$.ajax(settings).done(function (response) {
console.log(response);
});`
XHR方法
`var data = "appId=41KYR0EB&appKey=IIWCKKSR7NOQ&phone=1561894**&templateId=1043&variables=1234";
var xhr = new XMLHttpRequest();
xhr.withCredentials = true;
xhr.addEventListener("readystatechange", function() {
if(this.readyState === 4) {
console.log(this.responseText);}
});
xhr.open("POST", "https://vip.veesing.com/smsApi/verifyCode");
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
xhr.send(data);`
以上就是JavaScript实现短信验证码登录注册的3种方法，有疑问可以在评论区指出，欢迎和大家一起讨论。
