使用
eggjs脚手架安装项目，需要完成简单的数据库操作，使用插件egg-mysql，正常按照官方方式进行操作，结果却不尽人意，找不到解决方案，一头雾水，捣鼓了好几天，一步步的排错查询，终于解决，以下是踩坑中的解决方案和错误信息汇总
"egg": "^3.17.5",
"egg-mysql": "^4.0.0",
首先将两个配置文件附上
config.default.js
/**
* @param {Egg.EggAppInfo} appInfo app info
*/
module.exports = appInfo => {
/**
* built-in config
* @type {Egg.EggAppConfig}
**/
const config = exports = {};
// use for cookie sign key, should change to your own and keep security
config.keys = appInfo.name + '_1705563141102_525';
// add your middleware config here
config.middleware = [];
// add your user config here
const userConfig = {
// myAppName: 'egg',
};
config.security = {
csrf: {
enable: false,
ignoreJSON: true
},
domainWhiteList: ['*']
}
config.view = {
mapping: {'.html': 'ejs'}, // 左边写成.html，渲染时候会自动渲染成该格式文件
}
// 推荐 - 配置方式
config.mysql = {
// 单数据库信息配置
client: {
host: "localhost", // 主机
port: '3306', // 端口号
user: 'root', // 用户
password: 'password', // 密码
database: 'test', // 数据库名
},
app: true, // 是否挂载到app上，默认开启
agent: false, // 是否挂载到agent上，默认关闭
}
return {
...config,
...userConfig,
};
};
// 不推荐 - 配置方式
// exports.mysql = {
// // 单数据库信息配置
// client: {
// host: "localhost", // 主机
// port: 3306, // 端口号
// user: 'root', // 用户
// password: 'password', // 密码
// database: 'test', // 数据库名
// },
// app: true, // 是否挂载到app上，默认开启
// agent: false, // 是否挂载到agent上，默认关闭
// }
plugin.js/** @type Egg.EggPlugin */
module.exports = {
ejs: {
enable: true,
package: 'egg-view-ejs'
},
// 推荐 - 配置方式
mysql: {
enable: true,
package: 'egg-mysql'
}
};
// 不推荐 - 配置方式
// exports.mysql = {
// enable: true,
// package: 'egg-mysql'
// }
处理
mysql v8.x版本默认加密方式变化导致的问题，将以下脚本信息在数据库中执行，完成后便更改完成
为此，特意使用
node + express + mysql创建一个简易的demo来验证并辅助完成问题排查和解决
const mysql = require('mysql')
const express = require('express')
const app = express()
const conn = mysql.createConnection({
user: 'root',
password: 'password',
host: 'localhost',
database: 'test'
})
conn.connect(err=> {
if (!err) {
console.log('连接成功');
} else {
console.log('连接失败', err);
}
})
app.listen(3000, () => {
console.log('服务启动成功。。。');
})
// 获取用户信息
app.get('/userInfo', (req, res) => {
let sql = 'select id, name from list'
conn.query(sql, (err, data) => {
if (!err) {
console.log('获取数据成功', data);
res.send(data)
} else {
console.log('获取数据失败');
res.send('获取信息失败')
}
})
})
// 添加用户信息
app.post('/addInfo', (req, res) => {
console.log(req.query);
const {name} = req.query
console.log(name);
let sql = `insert into list(id, name) values(0, ?)`
conn.query(sql, name, async (err, data) => {
console.log(2);
if(!err) {
const id = data.insertId
console.log('插入成功', data);
const result = await getInfoById(id)
res.send(result)
} else {
console.log('插入失败', err);
}
})
})
// 用户列表
app.get('/user-list', (req, res) => {
const sql = 'select * from list'
conn.query(sql, (err, data) => {
if (!err) {
const result = {
list: data
}
res.send(result)
} else {
res.send([])
}
})
})
// 根据id, 获取用户信息
function getInfoById(id) {
if (!id) return
console.log('开始查询', id);
return new Promise((resolve, reject)=> {
const sql = `select id, name from list where id=${id}`
console.log(12);
conn.query(sql, (err, data) => {
console.log(err);
if (!err) {
console.log('返回结果', data);
resolve(data)
} else {
reject(null)
}
})
})
}
设置方式如下，这里推荐使用数据库连接工具来执行，通过试错之后表示这样更可靠（也可能是个人错觉，可供参考），如使用
DBeaver按此步骤执行，找到菜单栏【SQL编辑器】-> 【SQL编辑器】或【新建SQL编辑器】-> 将下面语句填入 -> 点击右键 ->【执行】-> 【执行SQL语句】或【执行SQL脚本】-> OVER
ALTER user 'root'@'localhost' identified with 'mysql_native_password' by 'password';
flush privileges;
debug配置和连接状态，可以将操作对象信息打印出来看一下
首先，检查mysql服务是否开启，这里的错误日志大概包含如下信息
...
Error: connect ECONNREFUSED ::1:3306
...
egg 的app对象上没有mysql，mysql未挂载到app上，为什么首先要附上这个，因为这个在整个操作流程中占比真的蛮重要的
