在 Nestjs 库中获取会话和请求数据

Question

我正在编写一个 nestjs 库，它启动与数据库的连接，提供多种功能（检索数据、插入数据等），并记录执行的查询。

import { Injectable, Inject, Logger } from '@nestjs/common';
import * as ActiveDirectory from 'activedirectory';
import { SECHELPER_CONNECT_OPTIONS } from './constants';
import {
  SechelperADFindResult,
  SechelperOptions,
  DatabaseResult,
  ActiveDirectoryResult,
} from './interfaces';
import * as ldap from 'ldapjs';
import { blacklistpassword } from './interfaces';
import { Connection, createConnection, QueryRunner } from 'typeorm';
import * as crypto from 'crypto';
import passwordValidator from 'password-validator';
import { format } from 'date-fns';
import * as _ from 'lodash';
import { REQUEST, HttpAdapterHost } from '@nestjs/core';
import { Request } from 'express';
import * as requestIp from 'request-ip';

@Injectable()
export class SechelperService {
  private _dbClient: Connection;

constructor(
    @Inject(SECHELPER_CONNECT_OPTIONS)
    private options: SechelperOptions,
    private readonly logger: Logger,
    private adapterHost: HttpAdapterHost,
    //@Inject(REQUEST) private readonly request: Request
  ) {}

  async connect(): Promise<any> {
    // create db connection if db options exist
    if (this.options.dbConnectOptions) {
      return this._dbClient
        ? this._dbClient
        : (this._dbClient = await createConnection(
            this.options.dbConnectOptions,
          ));
    }

    return false;
  }
}

如果我取消对 //@Inject(REQUEST) private readonly request: Request 的注释，我将无法对数据库进行查询（以及其他 Typeorm 功能）（为什么？NestJs - not getting Injectable to work on subscriber）。

那么，还有其他方法可以在库中获取请求数据吗？
