如何使用外部身份验证服务对用户进行身份验证？

Question

I have a microservice for logging in and user registration. After launch request on localhost:8080 with body { "username": "test", "password":"test"} i get an auth token like: { "token":"asdfsadfasdf..." } ,

And i must use this token in another microservice to authenticate user before launching request on my endpoint, And i have code like this:

import { Injectable } from "@nestjs/common";
import { AuthGuard } from "@nestjs/passport";

@Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {}

    @Get()
    @UseGuards(JwtAuthGuard)
    private async getHello(): Promise<void> {
        console.log("Hello world");
    }

@Module({
  imports: [
        JwtModule.register({
      secret: 'secretKey',
    }),
    JwtStrategy,
    PassportModule.register({ defaultStrategy: 'jwt' })
],
  providers: [AppService],
  controllers: [AppController]
})
export class AppModule{}

after launch my Get request i get an error:

[Nest] 10472   - 04.05.2021, 17:14:00   [ExceptionsHandler] Unknown authentication strategy "jwt" +3677ms
Error: Unknown authentication strategy "jwt"

strategy

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
    constructor() {
        super({
          jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
          secretOrKey: 'secret',
        });
    }
}

can someone tell me what I'm doing wrong and why my auth strategy is bad?

thanks for any help!

Move your JwtStrategy from the imports to the providers array. Providers never go in the imports array. Only modules belong there.
