微信小程序实现AES-128-ECB-UTF8-hex加密

最近写一个微信小程序的登陆，后端使用的是aes方式，具体模块是ECB，输出是hex，使用格式UTF-8

首先先下一个加密工具集合：CryptoJS

然后将src里面的代码放进我们的项目里面

然后在我们需要使用的js中，引入文件

const CryptoJS = require('../../libs/crypto-js/crypto-js.js');

然后是具体实现的function

/**
       * 加密
      */
      encrypt: function (data) {
        var key = "1111111111111111";
        var keyHex = CryptoJS.enc.Utf8.parse(key);
        var encrypted = CryptoJS.AES.encrypt(data, keyHex, {
          iv: [],
          mode: CryptoJS.mode.ECB,
          padding: CryptoJS.pad.Pkcs7
        });
    
        var encryptData = encrypted.ciphertext.toString().toUpperCase(); // hex
        // var encryptData = encrypted.toString().toUpperCase(); // base64
    
        return encryptData;
      },
      /**
       * 解密
       */
      decrypt: function (decodedData) {
        var key = "1111111111111111";
        var keyHex = CryptoJS.enc.Utf8.parse(key);
        var decrypted = CryptoJS.AES.decrypt({
          ciphertext: CryptoJS.enc.Hex.parse(decodedData)
          // ciphertext: CryptoJS.enc.Base64.parse(decodedData) // base64
        }, keyHex, {
            iv: [],
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
          });
    
        var decryptedData = decrypted.toString(CryptoJS.enc.Utf8);
        console.log("解密之后的结果:" + decryptedData);
    
        return decryptedData;
      }

我是用的加解密方式就是：
