一、前端

安装:前端项目目录下的终端
cnpm install vue-cookies
配置:main.js
import cookies from 'vue-cookies'
Vue.prototype.$cookies = cookies;

登录功能(Login.vue)

<script>
    export default {
        name: "Login",
        data() {
            return {
                username: '',
                password: '',
                mobile: '',
                sms: '',
                login_method: 'is_pwd',
                sms_interval: '获取验证码',
                is_send: false,
            }
        },
        methods: {
            send_sms() {
            },
            // 登录功能
            login_password() {
                // 判断用户名和密码是否正确
                if (this.username && this.password) {
                    // 用户名密码正确发送请求
                    this.$axios.post(this.$settings.base_url + '/user/login/', {
                        username: this.username,
                        password: this.password
                    }).then(response => {
                        console.log(response)
                        if (response.data.code == 100) {
                            // 把用户信息保存都cookie中
                            // this.$cookies.set(key, value, 过期时间(秒))
                            this.$cookies.set('token', response.data.token, '7d')
                            this.$cookies.set('username', response.data.username, '7d')

                            //登录成功关闭窗口(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.$emit('loginsuccess')
                        } else {
                            this.$message({
                                message: '用户名或密码错误',
                                type: 'error'
                            })
                        }
                    })
                } else {
                    this.$message({
                        message: '用户名或密码必填',
                        type: 'warning'
                    })
                }
            }
        }
    }
</script>

登录功能后显示登录注销(Head.vue)

<template>
    <div class="header">
        <div class="slogan">
            <p>老男孩IT教育 | 帮助有志向的年轻人通过努力学习获得体面的工作和生活</p>

            </ul>

            <div class="right-part">
                <!-- 3.当username没有值,不变,有值显示登录注销               -->
                <div v-if="!username">
                    <span @click="put_login">登录</span>

                    <span>注销</span>
                </div>
            </div>
            <Login v-if="is_login" @close="close_login" @go="put_register"/>
            <Register v-if="is_register" @close="close_register" @go="put_login"/>
        </div>
    </div>

</template>

<script>
    // 导入登录组件
    import Login from "./Login";
    import Register from "./Register";

    export default {
        name: "Header",
        data() {
            return {
                url_path: sessionStorage.url_path || '/',
                is_login: false,
                is_register: false,

                // 1.创建两个变量
                token:'',
                username:''
            }
        },
        methods: {

            this.url_path = this.$route.path;

            // 2.当页面一创建,就去cookie中取token和username
            this.username=this.$cookies.get('username')  // 取到就有值,取不到就为空
            this.token=this.$cookies.get('token')  // 取到就有值,取不到就为空

        },
        components: {
            Login,
            Register,
        },

    }
</script>

登录功能后刷新后显示登录注销

第一步:
<!--Login.vue-->
<script>
    export default {
        name: "Login",
        methods: {
            login_password() {
                if (this.username && this.password) {
                    this.$axios.post(this.$settings.base_url + '/user/login/', {
                        username: this.username,
                        password: this.password
                    }).then(response => {
                        // 1.给父组件Head传递一个事件,让它从cookie中取出token和username
                        this.$emit('loginsuccess')
                    })
</script>

第二步:
<!--Head.vue-->
<template>
    <div class="header">
        <div class="slogan">
            <p>老男孩IT教育 | 帮助有志向的年轻人通过努力学习获得体面的工作和生活</p>
        </div>
            <div class="right-part">
                <!-- 3.当username没有值,不变,有值显示登录注销               -->
                <div v-if="!username">
                    <span @click="put_login">登录</span>
                    <span class="line">|</span>
                    <span @click="put_register">注册</span>
                </div>
                  <div v-else>
                    <span>{{username}}</span>
                    <span class="line">|</span>
                    <span>注销</span>
                </div>
            </div>
            <!--  3.刷新页面loginsuccess,@close和Login中$emit一样的名字  -->
            <Login v-if="is_login" @close="close_login" @go="put_register" @loginsuccess="login_success"/>
            <Register v-if="is_register" @close="close_register" @go="put_login"/>
        </div>
    </div>

</template>

<script>
    // 导入登录组件
    import Login from "./Login";
    import Register from "./Register";

    export default {
        name: "Header",
        data() {
            return {
            }
        },
        methods: {
            close_register() {
                this.is_register = false;
            },
            login_success(){
                // 2.刷新页面会变成用户名和注册,一刷新会触发点击事件获取username和token
                this.username=this.$cookies.get('username')
                this.token=this.$cookies.get('token')
            }
        },
    }
</script>

                    <span @click="logout">注销</span>
                </div>
            </div>

        methods: {
            login_success(){
            },
            logout(){
                // 1.清除cookie
                this.$cookies.remove('token')
                this.$cookies.remove('username')
                // 2.把两个变量清空
                this.token=''
                this.username=''

总结

# cookies修改页面登录状态
1.重点cookies操作
this.$cookies.set('key',value,过期时间(秒))  # 保存cookies信息
this.$cookies.get('key')    # 获取cookies信息
this.cookies.remove('key')  # 删除cookies信息
