NestJS Axios 模块 - 无法解析依赖关系

Question

我在使用 NestJS Axios 模块时遇到了一个莫名其妙的问题。我像这样将它导入到我的模块中：

import { Module } from '@nestjs/common';
import { HttpModule } from '@nestjs/axios';
import { PassportModule } from '@nestjs/passport';

import { AuthController } from './auth.controller';
import { AuthService } from './auth.service';
import { AuthStrategy } from './auth.strategy';

@Module({
  controllers: [AuthController],
  providers: [AuthService],
  imports: [HttpModule, PassportModule, AuthStrategy],
})

我正尝试在我的 AuthStrategy 中使用它，如下所示：

import { PassportStrategy } from '@nestjs/passport';
import { Injectable } from '@nestjs/common';
import { HttpService } from '@nestjs/axios';
import { Strategy } from 'passport-oauth2';

@Injectable()
export class AuthStrategy extends PassportStrategy(Strategy) {
  constructor(private readonly httpService: HttpService) {
    super({
      authorizationURL: `${process.env['OAUTH_DOMAIN']}/authorize`,
      tokenURL: `${process.env['OAUTH_DOMAIN']}/oauth/token`,
      clientID: process.env['OAUTH_CLIENT_ID'],
      clientSecret: process.env['OAUTH_CLIENT_SECRET'],
      callbackURL: process.env['OAUTH_REDIRECT_URL'],
      scope: ['openid', 'email', 'profile'],
    });
  }

  async validate(accessToken: string): Promise<any> {
    const data = await this.httpService.get(`${process.env['OAUTH_DOMAIN']}/`, {
      headers: { Authorization: `Bearer ${accessToken}` },
    });

    console.log(data);
  }
}

但是我得到错误：

Error: Nest can't resolve dependencies of the AuthStrategy (?). Please make sure that the argument HttpService at index [0] is available in the AuthStrategy context.

我哪里错了？我已按照错误提示进行操作，但仍然无法正常工作

在您的应用程序的某处，您已将 AuthStrategy（提供程序）添加到模块的 imports 数组中。提供者永远不应出现在 imports 数组中。

您可以了解有关阅读和剖析错误消息的更多信息from the docs page。

There are a few gotchas, that are common. One is putting a provider in an imports array. If this is the case, the error will have the provider's name where <module> should be.
