本文阅读大概 10 分钟, 自己写加思考大概 1 ~ 2 小时。建议：代码可以手抄， 但不要复制。
1. 整体框架
2. 前端页面布局
使用 bootstrap 的 grids system 进行布局。页面规划如下：
在 bootstrap 的网址搜索 grids system。
一行分为12份，左边3份，为头像；右边9份，白色区域 cards，加上按钮创建 bot，获取 Bot 列表
在 views.user.bot.UserBotIndexView.vue 下修改，实现基本的个人 bot 信息展示。
<template> <div class="container"> <div class="row"> <div class="col-3"> <div class="card" style="margin-top: 20px;"> <div class="card-body"> <img :src="$store.state.user.photo" alt="" style="width: 100%;"> </div> </div> </div> <div class="col-9"> <div class="card" style="margin-top: 20px;"> <div class="card-header"> <span style="font-size: 130%;">我的Bot</span> <button type="button" class="btn btn-primary float-end"> 创建Bot </button> </div> <div class="card-body"> <thead> <tr> <th>名称</th> <th>创建时间</th> <th>操作</th> </tr> <tbody> <tr> <td>{{ bot.title }}</td> <td>{{ bot.createtime }}</td> <td> <button type="button" class="btn btn-secondary" style="margin-right: 10px;">修改</button> <button type="button" class="btn btn-danger">删除</button> </td> </tr> </tbody> </thead> </div> </div> </div> </div> </div></template>实现 refresh_bot，获取上节课的 API: /user/bot/getlist/ 查询 bot 列表，通过获取后端信息把数据展示在前端上。
<script>import { ref, reactive } from 'vue'import $ from 'jquery'import { useStore } from 'vuex'export default { const store = useStore(); const refresh_bots = () => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/getlist/", type: "get", headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { bots.value = resp; } }) } refresh_bots(); }}</script>获取用户信息成功：
3. 前端页面创建、修改、删除 Bot
3.1 创建一个 Bot
在点击 创建Bot 按钮的时候需要一个弹窗。在 bootstrap 中寻找一个 modals ：
在 views.user.bot.UserBotIndexView.vue 下修改，增加一个模态框，然后丰富模态框的内容。
<template> <div class="container"> <div class="row"> <div class="col-3"> <div class="card" style="margin-top: 20px;"> <div class="card-body"> <img :src="$store.state.user.photo" alt="" style="width: 100%;"> </div> </div> </div> <div class="col-9"> <div class="card" style="margin-top: 20px;"> <div class="card-header"> <span style="font-size: 130%;">我的Bot</span> <button type="button" class="btn btn-primary float-end"> 创建Bot </button> //增加一个模态框 <div class="modal fade" id="add-bot-btn" tabindex="-1"> <div class="modal-dialog modal-xl"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">创建Bot</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <div class="mb-3"> <label for="add-bot-title" class="form-label">名称</label> <input v-model="botadd.title" type="text" class="form-control" id="add-bot-title" placeholder="请输入Bot名称"> </div> <div class="mb-3"> <label for="add-bot-description" class="form-label">简介</label> <textarea v-model="botadd.sescription" class="form-control" id="add-bot-description" rows="3" placeholder="请输入Bot简介"></textarea> </div> <div class="mb-3"> <label for="add-bot-code" class="form-label">代码</label> <textarea v-model="botadd.content" class="form-control" id="add-bot-content" rows="3" placeholder="请输入Bot代码"></textarea> </div> </div> <div class="modal-footer"> //增加报错信息 <div class="error-message">{{ botadd.error_message }}</div> <button type="button" class="btn btn-primary" @click="add_bot">创建</button> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">取消</button> </div> </div> </div> </div> </div> <div class="card-body"> <thead> <tr> <th>名称</th> <th>创建时间</th> <th>操作</th> </tr> <tbody> <tr> <td>{{ bot.title }}</td> <td>{{ bot.createtime }}</td> <td> <button type="button" class="btn btn-secondary" style="margin-right: 10px;">修改</button> <button type="button" class="btn btn-danger">删除</button> </td> </tr> </tbody> </thead> </div> </div> </div> </div> </div></template>增加一个 add_bot 函数：
<script>import { ref, reactive } from 'vue'import $ from 'jquery'import { useStore } from 'vuex'export default { const store = useStore(); const botadd = reactive({ title: "", description: "", content: "", error_message: "", }); const refresh_bots = () => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/getlist/", type: "get", headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { bots.value = resp; } }) } refresh_bots(); //创建一个 bot const add_bot = () => { botadd.error_message = ""; $.ajax({ url: "http://127.0.0.1:8080/user/bot/add/", type: "post", data: { title: botadd.title, description: botadd.description, content: botadd.content, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { if (resp.error_message === "success") { botadd.title = ""; botadd.description = ""; botadd.content = ""; Modal.getInstance("#add-bot-btn").hide(); refresh_bots(); } else { botadd.error_message = resp.error_message; } } }) } return { bots, botadd, add_bot, } }}</script>创建完成后需要绑定前端的信息。在前面的地方加上 v-model，同时增加一个 触发事件。
<div class="modal-body"> <div class="mb-3"> <label for="add-bot-title" class="form-label">名称</label> <input v-model="botadd.title" type="text" class="form-control" id="add-bot-title" placeholder="请输入Bot名称"> </div> <div class="mb-3"> <label for="add-bot-description" class="form-label">简介</label> <textarea v-model="botadd.sescription" class="form-control" id="add-bot-description" rows="3" placeholder="请输入Bot简介"></textarea> </div> <div class="mb-3"> <label for="add-bot-code" class="form-label">代码</label> <textarea v-model="botadd.content" class="form-control" id="add-bot-content" rows="3" placeholder="请输入Bot代码"></textarea> </div> </div> <div class="modal-footer"> //增加报错信息 <div class="error-message">{{ botadd.error_message }}</div> <button type="button" class="btn btn-primary" @click="add_bot">创建</button> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">取消</button> </div>
如果创建 Bot 的时候时间出现问题：在后端的 pojo 里修改，加上时区：
package com.kob.backend.pojo;import com.baomidou.mybatisplus.annotation.IdType;import com.baomidou.mybatisplus.annotation.TableId;import com.fasterxml.jackson.annotation.JsonFormat;import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;import java.util.Date;@Data@NoArgsConstructor@AllArgsConstructorpublic class Bot { @TableId(type = IdType.AUTO) private Integer id; //在pojo里最好用Integer，否则会报警告 private Integer userId; //pojo里要用驼峰命名法和数据库的下划线对应 private String title; private String description; private String Content; private Integer rating; @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "Asia/Shanghai") private Date createtime; @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "Asia/Shanghai") private Date modifytime;}成功效果如下：
3.2 删除一个 Bot
增加一个 删除 bot 的函数：
<script>import { ref, reactive } from 'vue'import $ from 'jquery'import { useStore } from 'vuex'export default { const store = useStore(); const botadd = reactive({ title: "", description: "", content: "", error_message: "", }); const refresh_bots = () => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/getlist/", type: "get", headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { bots.value = resp; } }) } refresh_bots(); //创建一个 bot const add_bot = () => { botadd.error_message = ""; $.ajax({ url: "http://127.0.0.1:8080/user/bot/add/", type: "post", data: { title: botadd.title, description: botadd.description, content: botadd.content, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { if (resp.error_message === "success") { botadd.title = ""; botadd.description = ""; botadd.content = ""; Modal.getInstance("#add-bot-btn").hide(); refresh_bots(); } else { botadd.error_message = resp.error_message; } } }) } //删除一个 bot const remove_bot = (bot) => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/remove/", type: "post", data: { bot_id: bot.id, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { console.log(resp); if (resp.error_message === "success") { refresh_bots(); } } }) } return { bots, botadd, add_bot, remove_bot, } }}</script>同时需要在上文绑定 删除 按钮。
<div class="card-body"> <thead> <tr> <th>名称</th> <th>创建时间</th> <th>操作</th> </tr> <tbody> <tr> <td>{{ bot.title }}</td> <td>{{ bot.createtime }}</td> <td> <button type="button" class="btn btn-secondary" style="margin-right: 10px;">修改</button> <button type="button" class="btn btn-danger" @click="remove_bot(bot)">删除</button> </td> </tr> </tbody> </thead> </div>如果删除的时候提示没有权限，可能是因为后端的 RemoveServiceImpl.java 文件出错，在里面修改即可。
成功效果：
3.3 修改一个 Bot
在 views.user.bot.UserBotIndexView.vue 下修改。
<script>import { ref, reactive } from 'vue'import $ from 'jquery'import { useStore } from 'vuex'export default { const store = useStore(); const botadd = reactive({ title: "", description: "", content: "", error_message: "", }); const refresh_bots = () => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/getlist/", type: "get", headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { bots.value = resp; } }) } refresh_bots(); //创建一个 bot const add_bot = () => { botadd.error_message = ""; $.ajax({ url: "http://127.0.0.1:8080/user/bot/add/", type: "post", data: { title: botadd.title, description: botadd.description, content: botadd.content, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { if (resp.error_message === "success") { botadd.title = ""; botadd.description = ""; botadd.content = ""; Modal.getInstance("#add-bot-btn").hide(); refresh_bots(); } else { botadd.error_message = resp.error_message; } } }) } //删除一个 bot const remove_bot = (bot) => { $.ajax({ url: "http://127.0.0.1:8080/user/bot/remove/", type: "post", data: { bot_id: bot.id, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { console.log(resp); if (resp.error_message === "success") { refresh_bots(); } } }) } const update_bot = (bot) => { botadd.error_message = ""; $.ajax({ url: "http://127.0.0.1:8080/user/bot/update/", type: "post", data: { bot_id: bot.id, title: bot.title, description: bot.description, content: bot.content, }, headers: { Authorization: "Bearer " + store.state.user.token, }, success(resp) { if (resp.error_message === "success") { Modal.getInstance('#update-bot-modal-' + bot.id).hide(); refresh_bots(); } else { botadd.error_message = resp.error_message; } } }) } return { bots, botadd, add_bot, remove_bot, update_bot, } }}</script>修改每一个 bot 的时候需要有对应单独的一个模态框。
<template> <div class="container"> <div class="row"> <div class="col-3"> <div class="card" style="margin-top: 20px;"> <div class="card-body"> <img :src="$store.state.user.photo" alt="" style="width: 100%;"> </div> </div> </div> <div class="col-9"> <div class="card" style="margin-top: 20px;"> <div class="card-header"> <span style="font-size: 130%;">我的Bot</span> <button type="button" class="btn btn-primary float-end" data-bs-toggle="modal" data-bs-target="#add-bot-btn"> 创建Bot </button> <div class="modal fade" id="add-bot-btn" tabindex="-1"> <div class="modal-dialog modal-xl"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">创建Bot</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <div class="mb-3"> <label for="add-bot-title" class="form-label">名称</label> <input v-model="botadd.title" type="text" class="form-control" id="add-bot-title" placeholder="请输入Bot名称"> </div> <div class="mb-3"> <label for="add-bot-description" class="form-label">简介</label> <textarea v-model="botadd.sescription" class="form-control" id="add-bot-description" rows="3" placeholder="请输入Bot简介"></textarea> </div> <div class="mb-3"> <label for="add-bot-code" class="form-label">代码</label> <VAceEditor </div> </div> <div class="modal-footer"> <div class="error-message">{{ botadd.error_message }}</div> <button type="button" class="btn btn-primary" @click="add_bot">创建</button> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">取消</button> </div> </div> </div> </div> </div> <div class="card-body"> <table class="table table-hover"> <thead> <tr> <th>名称</th> <th>创建时间</th> <th>操作</th> </tr> </thead> <tbody> <tr v-for="bot in bots" :key="bot.id"> <td>{{ bot.title }}</td> <td>{{ bot.createtime }}</td> <td> <button type="button" class="btn btn-secondary" style="margin-right: 10px;" data-bs-toggle="modal" :data-bs-target="'#update-bot-modal-' + bot.id">修改</button> <button type="button" class="btn btn-danger" @click="remove_bot(bot)">删除</button> <div class="modal fade" :id="'update-bot-modal-' + bot.id" tabindex="-1"> <div class="modal-dialog modal-xl"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">修改Bot</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <div class="mb-3"> <label for="add-bot-title" class="form-label">名称</label> <input v-model="bot.title" type="text" class="form-control" id="add-bot-title" placeholder="请输入Bot名称"> </div> <div class="mb-3"> <label for="add-bot-description" class="form-label">简介</label> <textarea v-model="bot.sescription" class="form-control" id="add-bot-description" rows="3" placeholder="请输入Bot简介"></textarea> </div> <div class="mb-3"> <label for="add-bot-code" class="form-label">代码</label> </div> </div> <div class="modal-footer"> <div class="error-message">{{ bot.error_message }}</div> <button type="button" class="btn btn-primary" @click="update_bot(bot)">保存修改</button> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">取消</button> </div> </div> </div> </div> </td> </tr> </tbody> </table> </div> </div> </div> </div> </div></template>成功效果如下：
3.4 实现代码框
- 在 vue 界面添加依赖 vue3-ace-editor
- 添加组件
import { VAceEditor } from 'vue3-ace-editor';import ace from 'ace-builds';ace.config.set( "basePath", "https://cdn.jsdelivr.net/npm/ace-builds@" + require('ace-builds').version + "/src-noconflict/")<VAceEditor v-model:value="botadd.content" @init="editorInit" lang="c_cpp" theme="textmate" style="height: 300px" />
