在vue项目如何使用base64加密
作者：青衣浏阳
这篇文章主要介绍了在vue项目如何使用base64加密，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
vue项目使用base64加密
1.vue-cli 脚手架搭建前端项目中，使用base64加密传输数据
方法一
1.安装依赖
npm install --save js-base64
2.在main.js中引入
import Base64 from 'js-base64' Vue.use(Base64)
3.使用
Base64.encode(this.pwd);//加密 Base64.decode(this.pwd);//解密
方法二
在utils 文件夹下创建base64.js,写入下面代码
//1.加密解密方法使用：
//1.加密
// var str = '124中文内容';
// var base = new Base64();
// var result = base.encode(str);
// //document.write(result);
// //2.解密
// var result2 = base.decode(result);
// document.write(result2);
// //2.加密、解密算法封装：
function Base64() {
// private property
var _keyStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
// public method for encoding
this.encode = function (input) {
if(!input){ console.log('请传入要加密的值') return}
var output = "";
var chr1, chr2, chr3, enc1, enc2, enc3, enc4;
var i = 0;
input = _utf8_encode(input);
while (i < input.length) {
chr1 = input.charCodeAt(i++);
chr2 = input.charCodeAt(i++);
chr3 = input.charCodeAt(i++);
enc1 = chr1 >> 2;
enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
enc4 = chr3 & 63;
if (isNaN(chr2)) {
enc3 = enc4 = 64;
} else if (isNaN(chr3)) {
enc4 = 64;
}
output = output +
_keyStr.charAt(enc1) + _keyStr.charAt(enc2) +
_keyStr.charAt(enc3) + _keyStr.charAt(enc4);
}
return output;
}
// public method for decoding
this.decode = function (input) {
if(!input){ console.log('请传入要解密的值') return}
var output = "";
var chr1, chr2, chr3;
var enc1, enc2, enc3, enc4;
var i = 0;
input = input.replace(/[^A-Za-z0-9\+\/\=]/g, "");
while (i < input.length) {
enc1 = _keyStr.indexOf(input.charAt(i++));
enc2 = _keyStr.indexOf(input.charAt(i++));
enc3 = _keyStr.indexOf(input.charAt(i++));
enc4 = _keyStr.indexOf(input.charAt(i++));
chr1 = (enc1 << 2) | (enc2 >> 4);
chr2 = ((enc2 & 15) << 4) | (enc3 >> 2);
chr3 = ((enc3 & 3) << 6) | enc4;
output = output + String.fromCharCode(chr1);
if (enc3 != 64) {
output = output + String.fromCharCode(chr2);
}
if (enc4 != 64) {
output = output + String.fromCharCode(chr3);
}
}
output = _utf8_decode(output);
return output;
}
// private method for UTF-8 encoding
var _utf8_encode = function (string) {
string = string.replace(/\r\n/g,"\n");
var utftext = "";
for (var n = 0; n < string.length; n++) {
var c = string.charCodeAt(n);
if (c < 128) {
utftext += String.fromCharCode(c);
} else if((c > 127) && (c < 2048)) {
utftext += String.fromCharCode((c >> 6) | 192);
utftext += String.fromCharCode((c & 63) | 128);
} else {
utftext += String.fromCharCode((c >> 12) | 224);
utftext += String.fromCharCode(((c >> 6) & 63) | 128);
utftext += String.fromCharCode((c & 63) | 128);
}
}
return utftext;
}
// private method for UTF-8 decoding
var _utf8_decode = function (utftext) {
var string = "";
var i = 0;
let c =0, c1 =0, c2 = 0;
while ( i < utftext.length ) {
c = utftext.charCodeAt(i);
if (c < 128) {
string += String.fromCharCode(c);
i++;
} else if((c > 191) && (c < 224)) {
c2 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));
i += 2;
} else {
c2 = utftext.charCodeAt(i+1);
c1 = utftext.charCodeAt(i+2);
string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));
i += 3;
}
}
return string;
}
}
export default Base64
组件中使用
import base from '@/utils/base64' //引入 var base1 = new base(); var passWord=base1.encode(this.form.password) //加密
vue项目对路由参数进行base64加密
1.安装依赖
npm install --save js-base64
2.全局引入 main.js
import * as Base64 from 'js-base64' Vue.prototype.Base64 = Base64
3.在页面中使用
加密
<router-link
:to="{
path: '/List',
query: { info: Base64.encode(JSON.stringify({ title: '这里是标题', module: 2 })) }
}"
>更多
</router-link>getDetails(module, title, id) {
let param = {
module: module,
title: title,
articleId: id
}
this.$router.push({
path: '/details',
query: {
info: this.Base64.encode(JSON.stringify(param))
}
})
},解密
created() {
let param = JSON.parse(this.Base64.decode(this.$route.query.info))
}以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
