php实现短信验证

<?php
//命名空间
namespace app\index\controller;

use think\controller;
use app\index\module;

class Index extends controller{

public function Sms(){
//接受手机号 访问路由上index,php/phone/13012492778
$phone = post(‘phone‘);
$rand = rand(1000,9999);

$url = "http://api.chanyoo.cn/utf8/interface/send_sms.aspx?username=wgnoreognreo&password=cnjdskcnkds&content=验证码：".$rand."【短信提示】&receiver=".$phone; //URL为短信发送的api地址，返回为xml的方式
$file = file_get_contents($url); //跨域访问 访问外部网站get

//转换xml结果
$xml = simplexml_load_string($file);
$date = json_decode(json_encode($xml),TRUE); //如果成功，$date[‘message‘]返回“短信提交成功”

//进行对$date
if($date[‘message‘] == "短信提交成功"){
$Sms = Sms::create([ //成功后返回json格式的数据
"phone" => $phone,
"rand" => $rand,
]);
echo "存入成功！".$Sms;
};
}
