jeecgboot 前后端加密传输

jeecgboot前后端加密传输（登录）

参考地址：

1.后台登录接口得参数获取和解密

文件地址：jeecg-boot-module-system\src\main\java\org\jeecg\modules\system\controller\LoginController.java

导入aes加密处理类：AesEncryptUtil;

import org.jeecg.common.util.encryption.AesEncryptUtil;

用户名和代码得解密获取：部分代码如下

@ApiOperation("登录接口")
	@RequestMapping(value = "/login", method = RequestMethod.POST)
	public Result<JSONObject> login(@RequestBody SysLoginModel sysLoginModel){
	public Result<JSONObject> login(@RequestBody SysLoginModel sysLoginModel) throws Exception {


		Result<JSONObject> result = new Result<JSONObject>();
		String username = sysLoginModel.getUsername();
		String password = sysLoginModel.getPassword();
		/*String username = sysLoginModel.getUsername();
		String password = sysLoginModel.getPassword();*/
        //后台得解密
		String username = AesEncryptUtil.desEncrypt(sysLoginModel.getUsername(),EncryptedString.key,EncryptedString.iv).trim();
		String password = AesEncryptUtil.desEncrypt(sysLoginModel.getPassword(),EncryptedString.key,EncryptedString.iv).trim();

2.前端加密传输

文件地址：\src\views\user\Login.vue

data 添加变量,存储加密用到的key和iv：

Encrypteds:{
          key:"",
          iv:"",
        },

method 添加获取key和iv得方法：

//key iv 得初始化方法  
getEncrypteds(){
    var me = this;
    getAction(`/sys/getEncryptedString`).then((res)=>{
      me.Encrypteds.key = res.result.key
      me.Encrypteds.iv = res.result.iv
    })
  },

再在登录方法之前调用getEncrypteds（）完成初始化：就一行代码，放在loginByUsername（）之前就好

//登录
      handleSubmit () {
        let that = this
        let loginParams = {};
        that.loginBtn = true;
        // 使用账户密码登录
        if (that.customActiveKey === 'tab1') {
          this.getEncrypteds();//调用初始化方法
          this.loginByUsername();
        } else {
          this.loginByPhone()
        }
      },

username 和password得加密传输

              username: encryption(this.model.username,this.Encrypteds.key,this.Encrypteds.iv),
              password: encryption(this.model.password,this.Encrypteds.key,this.Encrypteds.iv),
