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) { 
            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) { 
            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;
            var c = c1 = 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);
                    c3 = 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
