这是一个php版本的demo,用于对接开关的API接口,可以控制开关的开和关,还有获取开关的状态
数据传输过程使用discuz加解密方法,个人密匙可以自己配置
1.demo文件
<?php
include('include/AuthCode.class.php');
$key = "d0d3d5b5466cc1ee89eb808de9f5672d";//个人密匙
$mid = "5b53a2d341d78427feafeb4520bf41eb";//设备密匙
$url = "https://wx663ca7ac2632b137.vip.aoyacms.com/plugin/aoya/iot/api.php";//接口地址
$t = time();//获取时间戳
//控制开关
$info = array(
"act" => "switch"
);
$json = json_encode($info);//将操作转成json格式
$ciphertext = AuthCode::encode($json,$key);//密文
$check = md5($t.$mid.$ciphertext);//md5验证
//获取开关状态
$info2 = array(
"act" => "getState"
);
$json2 = json_encode($info2);
$ciphertext2 = AuthCode::encode($json2,$key);//密文
$check2 = md5($t.$mid.$ciphertext2);//md5验证
?>

2.加解密类
<?php
class AuthCode {
public static function encode($str, $key) {
return self::_auth_code($str, 'ENCODE', $key, 0);
}
public static function decode($str, $key) {
return self::_auth_code($str, 'DECODE', $key, 0);
}
public static function _auth_code($string, $operation = 'DECODE', $key = '', $expiry = 3600) {
/***
* 随机密钥长度 取值 0-32;
* 加入随机密钥,可以令密文无任何规律,即便是原文和密钥完全相同,加密结果也会每次不同,增大破解难度。
* 取值越大,密文变动规律越大,密文变化 = 16 的 $ckey_length 次方
* 当此值为 0 时,则不产生随机密钥
*/
$ckey_length = 4;
$key = md5($key);
$keya = md5(substr($key, 0, 16));
$keyb = md5(substr($key, 16, 16));
$keyc = $ckey_length ? ($operation == 'DECODE' ? substr($string, 0, $ckey_length): substr(md5(microtime()), -$ckey_length)) : '';
$cryptkey = $keya.md5($keya.$keyc);
$key_length = strlen($cryptkey);
$string = $operation == 'DECODE' ? base64_decode(substr($string, $ckey_length)) : sprintf('%010d', $expiry ? $expiry + time() : 0).substr(md5($string.$keyb), 0, 16).$string;
$string_length = strlen($string);
$result = '';
$box = range(0, 255);
$rndkey = array();
for($i = 0; $i <= 255; $i++) {
