带有PassportModule自定义AuthGuard注入ConfigService的雀巢？

Question

我想知道如何在ConfigService中注入PassportModule AuthGuard中的自定义参数？

这是我的密码

auth.module.ts

@Module({
  imports: [
    PassportModule.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService): Promise<IAuthModuleOptions> => {
        return {}
      }
    }),
  ],
  // ...
})
export class AuthModule {}

github-auth.guard.ts

@Controller('auth')
export class AuthController {
  // ...

  @Get('github-oauth')
  @UseGuards(new GithubAuthGuard({}))
  async githubOAuth(@Req() req: Request, @Res() res: Response) {
    const user = req.user
    return await this.handleOauth(user, req, res)
  }
}

github-auth.guard.ts

import { ConfigService } from '@nestjs/config'
import { AuthGuard } from '@nestjs/passport'

@Injectable()
export class GithubAuthGuard extends AuthGuard('github') {
  constructor(private readonly configService: ConfigService) {
    super()
  }
  //...
}

我使用UseGuards调用new GithubAuthGuard({})，因为我希望传递自定义参数。

更新：

AuthGuard('github')返回一个被轮转的类，可以接受选项，然后传递给我的自定义策略的authenticate函数作为第二个参数。

这是我的github.strategy.ts

import { Strategy } from 'passport'

class StrategyFoo extends Strategy {
    constructor(options, verify) {
        //...
    }

    // options from AuthGuard('github')
    authenticate(req, options) {
        const self = this
        const redirect_uri = options.callbackURL || this._options.callbackURL
        // ...
    }
}

@Injectable()
export class GithubBarStrategy extends PassportStrategy(StrategyFoo, 'github') {
//...
}

export const GithubStrategy = GithubBarStrategy

经过一番研究，我想出了办法

巢不会在手动实例化的类上注入任何内容。

因此，只需调用@UseGuards(GithubAuthGuard)，然后在github-auth.guard.ts或github.strategy.ts中注入ConfigService，如：

注射github-auth.guard.ts

@Injectable()
export class GithubAuthGuard extends AuthGuard('github') {
  // @Inject(ConfigService)
  // private configService: ConfigService

  constructor(private readonly configService: ConfigService) {
    // 
    const options = {
      callbackURL: configService.get('OAuth.github.callbackURL'),
      //...
    }
    super(options)
  }

  getAuthenticateOptions(context) {
    // this also works
    return {
      callbackURL: this.configService.get('OAuth.github.callbackURL'),
      //...
    }
  }
  // ...
}

或

注射github.strategy.ts

class StrategyFoo extends Strategy {

  private _options: any
  constructor(options, verify) {
    //...
    this._options = options
    // ...
  }
  authenticate(req, options) {
    // ...
    let _options = {
    ...options,
    ...this._options
    }
    // ...
  }
}

@Injectable()
export class GithubBarStrategy extends PassportStrategy(StrategyFoo, 'github') {
  constructor(private readonly configService: ConfigService) {
    super({
      passReqToCallback: true,

      callbackURL: this.configService.get('OAuth.github.callbackURL'),
      // ...
    })
  }
  // ...
}
