流程
1. components中新建Login.vue文件, 写入如上代码
2. components中的Header.vue中. 导入组件, 注册组件, 使用组件
3. 登录注册绑定点击事件, 为Login组件使用条件渲染指令v-if, 指定一个值is_login控制Login组件的展示状态.
在点击登录按钮时is_login为True
在点击登录组件中×时, Login组件应该控制传递数据, 控制父组件的展示或者隐藏. 子组件对×绑定事件的传递this.$emit('close')
5. 父组件中的Login组件中获取到传递过来的事件@close. 绑定一个父组件中的触发该事的方法, 一当该事件触发, 表示用户×了登录界面. 此时is_login因该为false.

三、导航条：结合实际修改
<template>
<div class="nav">
<span @click="put_login">登录</span>
<span @click="put_register">注册</span>
<Login v-if="is_login" @close="close_login" @go="put_register" />
<Register v-if="is_register" @close="close_register" @go="put_login" />
</div>
</template>
<script>
import Login from "./Login";
import Register from "./Register";
export default {
name: "Nav",
data() {
return {
is_login: false,
is_register: false,
}
},
methods: {
put_login() {
this.is_login = true;
this.is_register = false;
},
put_register() {
this.is_login = false;
this.is_register = true;
},
close_login() {
this.is_login = false;
},
close_register() {
this.is_register = false;
}
},
components: {
Login,
Register
}
}
</script>
<style scoped>
</style>
四、登录业务分析
1. 多方式登录
"""
1）前台提供账号密码，账号可能是 用户名、手机号、邮箱等
接口：
后台只需要提供一个多方式登录接口即可 - 多方式登录接口
"""
2. 验证码登录
"""
1）前台提供手机号和验证码完成登录
接口：
前台填完手机号，往后台发送校验手机号的请求，如果存在继续，不存在提示注册 - 手机号存在与否接口
前台点击发送验证码，将手机再次发送给后台，后台将手机号通知给第三方，发送短信 - 手机验证码接口
前台点击登录提交手机号与验证码，完成验证码登录 - 验证码登录接口
"""
五、注册业务分析
验证码登录
"""
1）前台提供手机号、验证码、密码完成注册
接口：
前台填完手机号，往后台发送校验手机号的请求，如果不存在继续，存在提示登录 - 手机号存在与否接口
前台点击发送验证码，将手机再次发送给后台，后台将手机号通知给第三方，发送短信 - 手机验证码接口
前台点击注册提交手机号、验证码及密码，完成验证码注册 - 验证码注册接口
"""
六、总结
"""
1. 多方式登录接口
2. 手机号存在与否接口
3. 手机验证码接口
4. 验证码登录接口
5. 验证码注册接口
"""
