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。

javascript 复制代码 
<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。

html 复制代码 
<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>

                        <!-- Modal -->
                        <div class="modal fade" id="add-bot-btn" tabindex="-1">

                                </div>

                            </div>
                        </div>

                            </thead>
                            <tbody>
                                <tr v-for="bot in bots" :key="bot.id"> 
                                    <td>{{ bot.title }}</td>
                                    <td>{{ bot.createtime }}</td>

                                    </td>
                                </tr>
                            </tbody>
                        </table>
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

增加一个 add_bot 函数：

javascript 复制代码 
<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)

html 复制代码 
<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：

java 复制代码 
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：

javascript 复制代码 
<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/",

同时需要在上文绑定 删除 按钮。

html 复制代码 
<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。

            bots,
            botadd,

            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。
