对请求数据的加解密

介绍两种常见的对请求数据的加解密的方式，用来提高请求安全。

1、对数据进行混淆，然后再清除混淆内容

$this->data = I('');
if (isset($this->data['random']) && !empty($this->data['random'])) {
    $arr = [];
    foreach ($this->data as $k => $v) {
        if ($k != 'random') {
            $k = str_replace($this->data['random'], '', $k);
            $v = str_replace($this->data['random'], '', $v);
        }
        $arr[$k] = $v;
    }
    $this->data = $arr;
}

2、用AES加解密

$input = file_get_contents("php://input");
$params = json_decode($input, true);

if (is_array($params) && array_key_exists(ACTION_NAME, C('API_UUIDARR'))) {
    $arr = [];
    foreach ($params as $k => $v) {
        if (strpos($k, C('API_UUIDARR')[ACTION_NAME]) !== false) {
            $arr = $v;
        }
    }
    import('@.Lib.AesSecurity');
    $aes = new \AesSecurity();
    $decrypt = $aes->decrypt($arr);
    if (!empty($decrypt)) {
        $this->isaesparam = true;
        $res = explode(',', $decrypt);
        $response = [];
        foreach ($res as $k => $v) {
            $result = explode('@@', $v);
            if ($result[0] && array_key_exists($result[0], C('KEY_UUIDARR'))) {
                $response[C('KEY_UUIDARR')[$result[0]]] = $result[1];
            }
        }
        $this->data = $response;
    }
}
