第五章---创建个人中心页面（下）
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Botspan>
<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Botspan>
<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">
<h1 class="modal-title fs-5" id="exampleModalLabel">创建Both1>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close">button>
div>
<div class="modal-body">
<form>
<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" aria-describedby="emailHelp" 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.description" 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-code" rows="7" placeholder="请编写Bot代码">textarea>
div>
form>
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-striped 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;">修改button>
<button type="button" class="btn btn-danger">删除button>
td>
tr>
tbody>
table>
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';
import { Modal } from 'bootstrap/dist/js/bootstrap';
export default {
setup() {
const store = useStore();
let bots = ref([]);
const botadd = reactive({
title: "",
description: "",
content: "",
error_message: "",
});
const refresh_bots = () => {
$.ajax({
url: "http://127.0.0.1:3000/user/bot/getlist/",
type: "get",
headers: {
Authorization:"Bearer " + store.state.user.token,
},
success(resp) {
bots.value = resp;
}
})
}
refresh_bots();
const add_bot = () => {
botadd.error_message = "",
$.ajax({
url: "http://127.0.0.1:3000/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。(上方代码已加)
<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
@AllArgsConstructor
public 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。

<div class="row">
<div class="col-3">
<div class="card" style="margin-top: 20px;">

3.4 实现代码框
- 在 vue 界面添加依赖
vue3-ace-editor和ace-builds - 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" />
