• 文件形式

Hi,今天分享一个在vue中使用base64对用户名、密码进行加密的小案例。

我们是可以有两种方法的:

1.使用插件:js-base64

2.引入文件。

插件--js-base64

1.首先我们安装插件

npm install --save js-base64

2.项目中引入

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.创建utils/base64.js文件夹,复制以下代码

//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(this: any) {
    // private property
    var _keyStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
    // public method for encoding
    this.encode = function (input: string) {
        if (!input) { console.log('请传入要加密的值'); 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('请传入要解密的值'); 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.在文件中引入该文件

import {Base64} from 'js-base64'

3.使用

    //对用户名密码进行base64加密
    let baseUtil = new Base64();
    //对密码进行加密
    let encodePwd = baseUtil.encode(data.password);
    console.log("加密后的pwd", encodePwd);//密码:123123  加密为:MTIzMTIz

抓紧时间练起来吧,兄dei,再不练你就废啦!
