一、Base64加密解密
一、前端加密
一、方法 一
const that = this;
const copyruleForm = JSON.parse(JSON.stringify(that.ruleForm));
const c_clus_content = window.btoa(unescape(encodeURIComponent(this.ruleForm.c_clus_content)));
const c_clus_econtent = window.btoa(unescape(encodeURIComponent(this.ruleForm.c_clus_econtent)))
注：unescape()方法已经被弃用，不建议使用
二、方法 二
注：深拷贝处理
const that = this;
# 深拷贝
const copyruleForm = JSON.parse(JSON.stringify(that.ruleForm));
const c_clus_content = btoa(encodeURI(that.ruleForm.c_clus_content));
const c_clus_econtent = btoa(encodeURI(that.ruleForm.c_clus_econtent));
二、后端解密
一、方法 一
public ProdCompDuty update(ProdCompDutyDTO prodCompDutyDTO) {
ProdCompDuty field = prodCompDutyDTO.getField();
//Base64解密 责任中文内容和责任英文内容
if (StringUtil.isNotBlank(prodCompDutyDTO.getIsBase64()) && "true".equals(prodCompDutyDTO.getIsBase64())) {
byte[] bytes1 = Base64.getDecoder().decode(field.getC_clus_content());
String c_clus_content = new String(bytes1);
field.setC_clus_content(c_clus_content);
byte[] bytes2 = Base64.getDecoder().decode(field.getC_clus_econtent());
String c_clus_econtent = new String(bytes2);
field.setC_clus_econtent(c_clus_econtent);
}
ProdCompDutyDao.updateOne_odb_duty_no(field);
return field;
}
二、方法 二
public ProdCompDuty update(ProdCompDutyDTO prodCompDutyDTO) {
ProdCompDuty field = prodCompDutyDTO.getField();
//Base64解密 责任中文内容和责任英文内容
if (StringUtil.isNotBlank(prodCompDutyDTO.getIsBase64()) && "true".equals(prodCompDutyDTO.getIsBase64())) {
try {
String c_clus_content = URLDecoder.decode(new String(Base64.getDecoder().decode(field.getC_clus_content()), "utf-8"), "utf-8");
String c_clus_econtent = URLDecoder.decode(new String(Base64.getDecoder().decode(field.getC_clus_econtent()), "utf-8"), "utf-8");
field.setC_clus_content(c_clus_content);
field.setC_clus_econtent(c_clus_econtent);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
ProdCompDutyDao.updateOne_odb_duty_no(field);
return field;
}
三、前端加密解密
一、window浏览器环境
1、window.btoa() 将ascii字符串或二进制数据转换成 base64 编码过的字符串
2、window.atob() 函数用来解码被 base64 编码过的数据
# 方法名就是 btoa和 atob ，具体语法如下：
window.btoa('hellow World') // 编码 aGVsbG93IFdvcmxk
window.atob('aGVsbG93IFdvcmxk') // 解码 hellow World
注意：不适用于带中文解密，即window.btoa 与 window.atob 不支持中文，且 IE9 以下不支持atob、btoa
解决：btoa 不支持 Unicode 字符编码的问题编码时，先用 encodeURIComponent 对字符串进行编码，再进行 btoa 进行 Base64 编码解码时，先用 atob 对 Base64 编码的串进行解码，再用 decodeURIComponent 对字符串进行解码
var str = "hello,中国";
var encoded_str = btoa(encodeURIComponent(str));
var decoded_str = decodeURIComponent(atob(encoded_str));
console.log(encoded_str); // aGVsbG8lMkMlRTQlQjglQUQlRTUlOUIlQkQ=
console.log(decoded_str); // hello,中国在这里插入代码片
二、封装base64

方法使用
1、引用
import {Base64} from './utils/base64'
2、使用
Base64.encode('hellow world'); // 编码 aGVsbG93IFdvcmxk
Base64.decode('aGVsbG93IFdvcmxk'); // 解码 hellow World
三、开源的base64.js
1、下载依赖
$ npm install --save js-base64
2、使用方法：
import {Base64} from 'js-base64'
Base64.encode('hellow world'); // 编码 aGVsbG93IFdvcmxk
Base64.decode('aGVsbG93IFdvcmxk'); // 解码 hellow World
四、后端Base64工具类
一、base64加密解密（apache）
import org.apache.commons.net.util.Base64;
import java.io.UnsupportedEncodingException;
@SuppressWarnings("restriction")
public class BaseEncodeAndDecode {
//加密
public static String getBase64(String str){
byte[] b=null;
String s=null;
try {
b = str.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
if(b!=null){
s=Base64.encodeBase64String(b);
}
return s;
}
// 解密
public static String getFromBase64(String s) {
byte[] b = null;
String result = null;
if (s != null) {
try {
b = Base64.decodeBase64(s);
result = new String(b, "utf-8");
} catch (Exception e) {
e.printStackTrace();
}
}
return result;
}
}
二、base64加密解密（util）
import java.util.Base64;
public class BaseEncodeAndDecode {
//加密
private static String BaseEncodeAndDecode(String str) {
//String encodedString = Base64.getEncoder().encodeToString(str.getBytes());
String encodedString = Base64.getEncoder().withoutPadding().encodeToString(str.getBytes());
return encodedString;
}
//解密
private static String getFromBase64(String str) {
byte[] decodedBytes = Base64.getDecoder().decode(str);
String decodedString = new String(decodedBytes);
return decodedString;
}
}
