vue+node.js手把手教你搭建一个直播平台（五） 接入用户相关接口

hello，好久不见呀！ 老铁们，国庆过去了，该开始敲代码啦！赶紧瞧过来，告诉你们一个秘密，小羽悄咪咪的更新了~

不用怕，这节的内容比较简单，刚刚跟祖国母亲过完生日，脑子里还是想着怎么玩呢，哈哈哈！！！所以这节主要讲最常见的登录注册接口接入【狗头保命】

1.api接口相关

在src/api/modules新建user.js文件。在src/api/index.js中引入user.js。

/*

 */
import baseEnv from "@/assets/js/env.js"
import axios from "@/assets/js/http.js"

class User{
    /**
     * @description: 用户登录接口
     * @Date: 2020-09-03 10:00:32
     * @author: 小羽
     * @param {type} 
     * @return {type} 
     */
    userLogin(params){
        return axios.post(`${baseEnv.webUrl}/users/login`,params).then(res=>{
            return res.data
        })
    }

    /**
     * @description: 获取用户信息
     * @Date: 2020-08-31 16:03:52
     * @author: 小羽
     * @param {type} 
     * @return {type} 
     */
    getUserInfo(id="LNsKeo69KLCuGrbNg0nlg2jwQDQub28C"){
        return axios.get(`${baseEnv.webUrl}/users/getUserInfo`,{params:{id:id}}).then(res=>{
            return res.data
        })
    }

    /**
     * @description: 新增用户
     * @Date: 2020-08-31 16:06:33
     * @author: 小羽
     * @param {type} 
     * @return {type} 
     */
    addUser(params){
        return axios.post(`${baseEnv.webUrl}/users/addUser`,params).then(res=>{
            return res.data
        })
    }
}
const user = new User()
export default user

 */
import livingRoomApi from "./modules/livingRoom"
import userApi from "./modules/user"

const apiObj = {
    livingRoomApi,
    userApi
}
export default apiObj

2.新增用户store

像用户相关信息的这种数据，可能会有很多个页面会用到，属于公共数据来着，总不能我们每次都要从数据库里面拉取我们想要数据吧，这样就会浪费很多不必要的资源，那可怎么办呢？聪明的小伙伴们一听到公共数据就想到解决方案了。没错，是它，是它，就是它，我们的英雄vuex~

src/store/modules中新增user.js

/*
 * @description: 
 * @author: 小羽
 * @lastEditors: 小羽
 * @Date: 2020-09-01 13:43:51
 * @LastEditTime: 2020-10-15 01:16:59

 */
const state = {
    currentUser:{},
    token:""
}
const actions = {}
const mutations = {
    updateCurrentUser(state,data){
        state.currentUser = data
    },
    updateToken(state){
        state.token = localStorage.getItem("living_token")
    }
}
const getters = {}

export default {
    state,
    actions,
    mutations,
    getters
}

修改src/store/index.js，引入刚刚新增的user.js

/*
 * @description: vuex统一入口
 * @author: 小羽
 * @lastEditors: 小羽
 * @Date: 2020-09-01 13:41:36
 * @LastEditTime: 2020-10-15 01:17:43
 * @Copyright: 1.0.0
 */
import Vue from 'vue'
import Vuex from 'vuex'
import room from "./modules/room"
import user from "./modules/user"
Vue.use(Vuex)

export default new Vuex.Store({
    modules:{
        room,
        user
    }
})

3.登录注册切图

修改头部导航组件中的登录注册模块，修改的地方如下。主要就是加入了登录注册的弹窗。

<div class="live-header-right">
            <Dropdown v-if="token&&currentUser.id">
                <section class="live-header-right-user">
                    <div class="live-header-right-user-avatar">
                        <img :src="currentUser.avatar"/>
                    </div>
                    <div class="live-header-right-user-name">
                        <div>{{currentUser.name}}</div>
                    </div>
                </section>
                <DropdownMenu slot="list">
                    <DropdownItem>
                        <div @click="userLogout">退出登录</div>
                    </DropdownItem>
                </DropdownMenu>
            </Dropdown>
            <section class="live-header-right-user" v-else>
                <div class="live-header-right-user-loginbtn" @click="loginPopupShow=true">登录/注册</div>
            </section>
        </div>
        <section>
            <Modal v-model="loginPopupShow" width="350px" :mask-closable="false" :footer-hide="true" :transfer="false">
                <Tabs>
                    <TabPane label="登录">
                        <Input name="account" style="margin:10px 0" prefix="ios-contact" placeholder="请输入账号" type="text" v-model="loginData.account" />
                        <Input name="password" style="margin:10px 0" prefix="ios-contact" placeholder="请输入密码" type="password" v-model="loginData.password"/>
                        <div align="right" style="margin-top:30px">
                            <Button type="primary" @click="userLogin">登录</Button>
                        </div>
                    </TabPane>
                    <TabPane label="注册">
                        <Form ref="registerData" :model="registerData" :rules="ruleRegistValidate" :label-width="60">
                            <FormItem label="昵称" prop="name">
                                <Input v-model="registerData.name" placeholder="请输入昵称" />
                            </FormItem>
                            <FormItem label="邮箱" prop="email">
                                <Input v-model="registerData.email" placeholder="请输入邮箱" />
                            </FormItem>
                            <FormItem label="密码" prop="password">
                                <Input v-model="registerData.password" placeholder="请输入密码" />
                            </FormItem>
                        </Form>
                        <div align="right">
                            <Button type="primary" @click="userRegister('registerData')">注册</Button>
                        </div>
                    </TabPane>
                </Tabs>
            </Modal>
        </section>

修改头部组件的js脚本如下

<script>
import {mapActions,mapMutations,mapGetters,mapState} from "vuex"
export default {
    name:"liveHeader",
    data(){
        return {
            searchInfo:"",
            loginData:{
                account:"",
                password:"",
            },
            registerData:{
                name:"",
                email:"",
                password:""
            },
            ruleRegistValidate:{
                name: [
                    { required: true, message: '昵称不能为空', trigger: 'blur' }
                ],
                email: [
                    { required: true, message: '邮箱不能为空', trigger: 'blur' },
                    { type: 'email', message: '邮箱格式不正确', trigger: 'blur' }
                ],
                password: [
                    { required: true, message: '密码不能为空', trigger: 'blur' },
                    { type: 'string', min: 6,max:20, message: '密码长度为6~20', trigger: 'blur' }
                ],
            },
            loginPopupShow:false,
        }
    },
    computed:{
        ...mapState({
            currentUser:state=>state.user.currentUser,
            token:state=>state.user.token
        })
    },
    mounted(){
    },
    methods:{
        ...mapActions([
            "setRoomList"
        ]),
        ...mapMutations(["updateRoomList","updateCurrentUser","updateToken"]),

                await this.updateCurrentUser(res.data)
                this.loginPopupShow=false
                this.$Message.success({
                    background: false,
                    content: '登录成功'
                });
                console.log(this.currentUser)
            })
        },

        async userLogin(){
            console.log("userLogin -> this.loginData", this.loginData)

        userRegister(name){
            console.log("userRegister -> this.$refs[name]", this.$refs[name])
            this.$refs[name].validate((valid) => {
                if (valid) {
                    //this.$Message.success('Success!');
                    let data = {
                        ...this.registerData,
                        age:18
                    }
                    this.$api.userApi.addUser(data).then(res=>{
                        console.log("userRegister -> res", res)
                        this.$Message.success("注册成功")
                    }).catch(err=>{
                        this.$Message.error("注册失败")
                    })
                } else {
                    this.$Message.error('验证失败!');
                }
            })
        },
    }
}
</script>

然后试一下，登录/退出功能正常。

再试一下注册功能，哦豁，报错了！！！ 查看报错文件，401token异常的报错，小case啦，后端加上白名单就ok啦~

app.use(expressJwt({
  secret:"living_xiaoyu",
  algorithms:['HS256'],
  credentialsRequired:true, //是否校验
}).unless({
  path:['/users/login','/livingRoom/roomList','/livingRoom/roomListByType','/livingRoom/roomDetail','/users/addUser']
}))

小结

帅到睡不着的小羽在本期主要带老铁们，接入直播平台的用户相关api接口，内容比较容易，都是聪明的童鞋们，一看就懂~

但是小羽还是得厚着脸皮（这帅气的小脸都不要了，呜呜呜），硬着头皮来骗波点赞和关注~

下期预告，不出意外的话，讲解弹幕模块相关。
