目錄插件--js-base64文件形式總結

Hi,今天分享一個在vue中使用base64對用戶名、密碼進行加密的小案例。

我們是可以有兩種方法的：

1.使用插件:js-base64

2.引入文件。

插件--js-base64

1.首先我們安裝插件

npm install --save js-base64

2.項目中引入

import {Base64} from 'js-base64'

3.使用

let encodePwd=Base64.encode(password);//加密let decodePwd=Base64.decode(encodePwd);//解密文件形式

1.創建utils/base64.js文件夾,復制以下代碼

//1.加密解密方法使用：//1.加密// var str = '124中文內容';// 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、解密算法封裝：function Base64(this: any) { // private property var _keyStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/='; // public method for encoding this.encode = function (input: string) {if (!input) { console.log('請傳入要加密的值'); return }var output = '';var chr1: number, chr2: number, chr3: number, enc1: number, enc2: number, enc3: number, enc4: number;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: string) {if (!input) { console.log('請傳入要解密的值'); return }var output = '';var chr1: number, chr2: number, chr3: number;var enc1: number, enc2: number, enc3: number, enc4: number;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 = 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: string) {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) | (c1 & 63));i += 3; }}return string; }}export default Base64

2.在文件中引入該文件

import {Base64} from 'js-base64'

3.使用

//對用戶名密碼進行base64加密 let baseUtil = new Base64(); //對密碼進行加密 let encodePwd = baseUtil.encode(data.password); console.log('加密后的pwd', encodePwd);//密碼:123123 加密為:MTIzMTIz

抓緊時間練起來吧，兄dei，再不練你就廢啦！
