我正在尝试使用mysql_clear_password插件连接到 MySQL 服务器。我设置连接配置node-mysql2如下:

const connectionConfig = {
  host: rwConfig.host,
  user: rwConfig.user,
  database: rwConfig.database,
  ssl: {
    ca: sslContent
  },
  password
}

然后为了支持mysql_clear_password插件,我添加了以下内容(我使用的参考链接:https ://github.com/sidorares/node-mysql2/issues/438#issuecomment-255343793 ):

connectionConfig.authSwitchHandler = (data, cb) => {
  console.log('In auth switch handler');
  if (data.pluginName === 'mysql_clear_password') {
    console.log(data);
    console.log(data.pluginData.toString('utf8'));
    console.log('In mysql clear password');
    var tmppassword = connectionConfig.password + '\0';
    var buffer = Buffer.from(tmppassword, 'base64');
    cb(null, buffer);
  }
};

这在我尝试连接到我的数据库时有效。

现在我尝试使用 knexjs 做类似的事情。我使用以下配置对象:

const knexConfig = {
  client: 'mysql2',
  connection: connectionConfig,
  pool: {
    min: 0,
    max: 20
  },
  acquireConnectionTimeout: 10000
};

connectionConfig作为值传入的Iconnection与我用于连接的对象相同node-mysql2。然后我创建一个 knex 连接:

const rwConnection = knex(knexConfig);

由于某种原因,这会引发此错误:

{ Error: Client does not support authentication protocol requested by server; consider upgrading MySQL client

code: 'ER_NOT_SUPPORTED_AUTH_MODE',
errno: 1251,
sqlState: '#08004' }

我不知道为什么这给了我错误。在 knex 文档(http://knexjs.org/)中它说:

The connection options are passed directly to the appropriate database client to create the connection, and may be either an object, or a connection string

基于此,我认为它只会通过配置并使用node-mysql2. 任何帮助,将不胜感激。

我发现了这个问题,它现在可以工作了。Knex 没有将所有属性传递给 msyql2 客户端。

这是我为其他可能遇到此问题的人所做的。我修改了 knex 传递给 mysql2 的配置node_modules/knex/lib/dialect/mysql2并添加authSwitchHandler到 configOptions 数组中。
