Question

数据输入的值使用AES-128机制进行编码，其中前16个字符是我的应用程序的client_secret，它是解码过程的关键。我试图对其进行解码，但无法正常工作。我试过的代码 `

const express=require('express');
const bodyParser=require('body-parser');
var app=express();
var crypto=require('crypto');
app.use(express.static(__dirname+'/public'));
app.use(bodyParser.urlencoded({extended:true}));
app.post('/',(req,res)=>{
    var app_secret_key="my secret key";
    var abc=JSON.stringify(req.body.data);
    var key_app_secret_key=app_secret_key.substring(0,16);
    function decrypt(key,data){
        var decipher = crypto.createDecipher('aes-128-cbc',key);
        var decrypted = decipher.update(data,'binary', 'utf8');
        decrypted += decipher.final('utf8');
        return decrypted;
    }
    console.log(decrypt(key_app_secret_key,abc));
 });
app.listen(3000,()=>{
    console.log('Server running in port 3000');
})

` 我在下面附加的错误。请告诉我如何解决此问题。提前致谢。
