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
