使用 Mongodb nodejs 驱动程序版本 4 更新到 Mongoose 6 时，出现以下错误：

MongoInvalidArgumentError: No AuthProvider for DEFAULT defined.

我没有设置任何身份验证（这是我的本地开发环境），所以我不明白问题出在哪里。以下是相关的连接代码：

let connectionURL = 'mongodb://';
const connectionOptions = {
  authSource: options.authSource,
};

if (options.user && options.password) {
  connectionURL += `${options.user}:${options.password}@`;
}

connectionURL += `${options.host}/${dbName}?authSource=${options.authSource}`;

mongoose
  .connect(connectionURL, connectionOptions, function onConnected(err) {
    if (err) {
      return cb(new Error(`Can not connect to database ${dbName}`));
    }

    return cb(null, mongoose.connection);
  });

对于无密码/无用户连接，请确保连接 url 不包含authSource对我有用。这在驱动程序版本 4 之前以某种方式工作，但不再有效。

此外，要么选择在对象中传递选项，要么在连接字符串中传递选项。正如文档所说：

最佳实践是将开发和生产之间可能不同的选项（如 replicaSet 或 ssl）放在连接字符串中，并将应保持不变的选项（如 connectTimeoutMS 或 poolSize）放在选项对象中

const connectionOptions = {};

if (options.user && options.password) {
  connectionOptions.user = options.user;
  connectionOptions.password = options.password;
  connectionOptions.authSource = options.authSource;
}

const connectionURL = `mongodb://${options.host}/${dbName}`;

mongoose
  .connect(connectionURL, connectionOptions, function onConnected(err) {
    if (err) {
      return cb(new Error(`Can not connect to database ${dbName}`));
    }

    return cb(null, mongoose.connection);
  });
};
