TypeError：无法读取未定义的属性“random”-crypto-js

javascript reactjs cryptojs

我在 reactjs 中使用 crypto-js ，在 localhost 上一切正常。但在使用 chrome 的服务器上，我收到此错误消息：

TypeError: Cannot read property 'random' of undefined

在 Firefox 上：

TypeError: "r is undefined"

我的代码：

import CryptoJS from 'crypto-js';

console.log('text',text); //printed on console as well
var p = randomString(10) 
console.log('p',p) //printed on console as well
var c = CryptoJS.AES.encrypt(text,p).toString(); // error line
console.log('crypted',c+p)//not printed !

我的函数：

  function setWindow(text){
    console.log('text',text);
    var p = randomString(10)
    console.log('p',p)
    var c = CryptoJS.AES.encrypt(text,p).toString();
    console.log('crypted',c+p)
    return c+p;
  }

"crypto-js": "^3.1.9-1",

我不知道问题出在哪里！我删除了 node_modules ，但仍然收到相同的错误。我的网站： http://posweb.ccg24.com/signin

已更新

  function randomString(length) {
    var text = "";
    var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

    for (var i = 0; i < length; i++)
      text += possible.charAt(Math.floor(Math.random() * possible.length));

    return text;
  }

无需使用 Math.random 即可生成随机数

var _ = require('lodash');
var CryptoJS = require("crypto-js");
var p;
function randomString(length) {
  var text = "";
  var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

 var text= _.sampleSize(possible , length).join('');

  return text;
}

function setWindow(text){
    console.log('text',text);
     p = randomString(10)
    console.log('p',p)
    var c = CryptoJS.AES.encrypt(text,p).toString();
    console.log('crypted',c+p)
    return c+p;
  }



var ciphertext=setWindow("plain text");
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), p);
var plaintext = bytes.toString(CryptoJS.enc.Utf8);

console.log("decrypte",plaintext);

function randomString(length) {
    var text = "";
    var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

    for (var i = 0; i < length; i++)
      text += possible.charAt(Math.floor(Math.random() * possible.length));

    return text;
  }




function setWindow(text){
 

    console.log('text',text);
    var p = randomString(10)
    console.log('p',p)
    var c =CryptoJS.AES.encrypt(text,p);
    console.log('crypted',c+p)
    return c+p;
}
var text="Plain Text";
setWindow(text);

Answer 2

您可以尝试：

import * as CryptoJS from 'crypto-js';
