1. php加密->js解密 没有任何问题

2.

3. 附上，刚刚热腾腾的 PHP openssl(7.x淘汰encrypt)<=> js  AES互相转换，
网上的教程都有问题。。。。
PHP

<?php
declare(strict_types=1);
namespace app\common\unit;

use think\Exception;

/**
 * Class AES128CBC
 * @package app\common\unit
 * Auth
 */
class AES128CBC
{
    private $vi='123456789abcdefg';  //VI需要指定16位
    private $key='';
    private $method='AES-128-CBC';
    public $error;

    public function __construct(string $key='',$vi='')
    {
        if(!empty($vi)){
            $this->vi=$vi;
        }
        if(empty($key)){
            throw  new Exception('AES加密必须传入key' );
        }
        $this->key=$key;
    }

    public function encrypt($str){
        $decode = base64_encode(openssl_encrypt($str,$this->method,$this->key,OPENSSL_RAW_DATA,$this->vi));
        if($decode){
            return $decode;
        }

        $this->error=__CLASS__.'解密失败!'.json_encode(['vi'=>$this->vi,'key'=>$this->key]);

        throw new Exception($this->error);
    }

    public function decrypt($str){

        $encode = openssl_decrypt(base64_decode($str),$this->method,$this->key,OPENSSL_RAW_DATA,$this->vi);
        if($encode){
            return $encode;
        }
        $this->error=__CLASS__.'加密失败!'.json_encode(['vi'=>$this->vi,'key'=>$this->key]);;
        throw new Exception($this->error);
    }

    public function getError(){
        return $this->error;
    }

    public function setVi($vi){
        $this->vi=$vi;
        return $this;
    }

    public function setKey($key){
        $this->key=$key;
        return $this;
    }

    public static function encode($k,$vi,$data){
        $_t=new self($k,$vi);
        return $_t->encrypt($data);
    }

    public static function decode($k,$vi,$data){
        $_t=new self($k,$vi);
        return $_t->decrypt($data);
    }
}

JS,需要预先定义钥匙key与VI (window.env.aes_key,window.env.aes_vi)

	<script type="text/javascript" src="js/aes.js"></script>
	function aesEncrypt(str) {
	    var key = CryptoJS.enc.Utf8.parse(window.env.aes_key);
	    var iv = CryptoJS.enc.Utf8.parse(window.env.aes_vi);
	    var encrypted = CryptoJS.AES.encrypt(str,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.Pkcs7});
		if(encrypted==null){
			throw "无法加密数据:"+str;
		}
	    return encrypted.toString();
	}
				
	// 解密
	function aesDecrypt(str) {
	    var key = CryptoJS.enc.Utf8.parse(window.env.aes_key);
	    var iv = CryptoJS.enc.Utf8.parse(window.env.aes_vi);
	    var decrypted = CryptoJS.AES.decrypt(str,key,{iv:iv,padding:CryptoJS.pad.Pkcs7});
		if(decrypted==null){
			throw "无法解密数据:"+str;
		}
	    return decrypted.toString(CryptoJS.enc.Utf8);
	}
