“客户端不支持身份验证协议”尝试使用 NestJs 应用程序连接到本地 MySql 数据库

问题描述 投票:0回答:2

我正在尝试将我的 NestJs 应用程序连接到本地的 MySql 数据库。 加入 NestJs 文档 .

我收到此错误消息:

[Nest] 8696  - 24/08/2023 15:14:40   ERROR [ExceptionHandler] ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client

这是我的数据库提供商:

import { DataSource } from 'typeorm';

export const databaseProviders = [
  {
    provide: 'DATA_SOURCE_LOCAL',
    useFactory: async () => {
      const dataSource = new DataSource({
        type: 'mysql',
        host: '127.0.0.1',
        port: 3306,
        username: 'root',
        password: 'root',
        database: 'myDb',
        entities: [myEntities],
        synchronize: true,
        insecureAuth: true,
      });

      return dataSource.initialize();
    },
  },

提供商示例 (user.prividers.ts) :

import { DataSource } from 'typeorm';
import {User} from './user.entity';
import { Profile } from './profile.entity';

export const userProviders = [
  {
    provide: 'USER_REPOSITORY',
    useFactory: (dataSource: DataSource) => dataSource.getRepository(User),
    inject: ['DATA_SOURCE_LOCAL'],
  }
];

随着文档的预先确定,我使用“mysql2”和“typeorm”: 我的package.json文件:

    "ts-node": "^10.0.0",
    "tsconfig-paths": "4.2.0",
    "typescript": "^4.7.4"
  },

我精确地说了一件“有趣”的事情。 每次运行应用程序时,我都会在数据库中获得一个(且只有一个)新表/实体。

我有 4 个实体(测验、问题、用户、个人资料)。 Id 表“测验”已在数据库中设置,并且我运行应用程序,它将因上述消息而崩溃,但“问题”表将被创建。

我已经尝试过这个方法了:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
flush privileges;

但是,尽管事实上它不起作用,但这似乎不是一个好的实践(就像在这个主题中)并且在每种情况下都可用(例如云数据库)。

我质疑自己在数据库提供程序中使用“mysql”类型是否需要文档中的“mysql2”(在应用程序中找不到)。

我在 Node.js 中读到了有关“mysql2”的内容,例如将其添加到 index.js 中:

const mysql = require('mysql2')

但我不知道如何将其与 NestJs 一起使用。

mysql nestjs database-connection typeorm nestjs-typeorm

mysql
npm 模块仍然不支持 MySQL 8 中引入的
caching_sha2_password
身份验证。因此,解决方案是切换到支持的
mysql2
npm 模块。

对于我来说 我必须卸载mysql然后安装mysql2

` npm 卸载 mysql

` 然后

npm 安装 mysql2

它对我有用。
