cookies修改页面登陆状态

1 重点，cookie操作
    this.$cookies.set('key',value,过期时间秒)
    this.$cookies.get('key')
    this.$cookies.remove('key')
2 
# template
<el-button type="primary" @click="login_password">登录</el-button>
#js
login_password() {
    if (this.username && this.password) {
        //发送请求
        this.$axios.post(this.$settings.base_url + '/user/login/', {
            username: this.username,
            password: this.password


        }).then(response => {
            console.log(response.data)
            //把用户信息保存到cookie中
            // this.$cookies.set('key','value','过期时间,按s计')
            this.$cookies.set('token',response.data.token,'7d')
            this.$cookies.set('username',response.data.username,'7d')
            //关闭登录窗口(子传父)
            this.$emit('close')
            //给父组件，Head传递一个事件，让它从cookie中取出token和username
            this.$emit('loginsuccess')
        }).catch(errors => {
        })
    } else {
        this.$message({
            message: '用户名或密码必须填哦',
            type: 'warning',

        });
    }
},

前台注销

# Head.vue
### template
<span @click="logout">注销</span>
### js
logout(){
    //清除cookie
    this.$cookies.remove('token')
    this.$cookies.remove('username')
    //把两个变量值为空
    this.username=''
    this.token=''
},

# views.py
