nestjs 中的“排除”未按预期工作

Question

我想在用户架构中排除密码字段。但我想不通。

UserSchema.ts

export type UserDocument = User & Document;

@Schema()
export class User extends BaseSchema {

    @Prop({ type: String })
    firstName: string;

    @Prop({ type: String })
    lastName: string;

    @Prop({ type: String, required: true, unique: true })
    email: string;

    @Prop({ type: String })
    phone: string;

    @Prop({ type: String, required: true, unique: true })
    userName: string;

    @Exclude()
    @Prop({ type: String, required: true })
    password: string;

    @Prop({ type: String })
    avatar: string;

}

export const UserSchema = SchemaFactory.createForClass(User);

UserController.ts

@UseInterceptors(ClassSerializerInterceptor)
    @Get(':id')
    public async getUserById(@Param('id') id: string): Promise<ResponseDto> {
        try {
            const result = await this.userService.getOne({ _id: id });
            return new ResponseDto({
                isSuccess: true,
                message: 'ok',
                data: result
            });

        } catch (error) {
            return new ResponseDto({
                isSuccess: false,
                message: error,
                data: null
            });
        }
    }

这是 UserService.ts

@Injectable()
export class UserService {

    constructor(
        @InjectModel('User') private readonly userModel: Model<UserDocument>
    ) { }

    public async getMany(query: object): Promise<User[]> {
        const users: User[] = await this.userModel.find(query).exec();
        return users;

    }


    public async getOne(query: object): Promise<User> {
        const user = await this.userModel.findOne(query).exec();
        return user;
    }


    public async deleteOne(query: object): Promise<any> {
        const result = await this.userModel.deleteOne(query).exec();
        if (result.n === 0) {
            throw new HttpException('Not deleted', 400);
        }
        return result;
    }

    public async deleteMany(query: object): Promise<any> {
        const result = await this.userModel.deleteMany(query).exec();
        if (result.n === 0) {
            throw new HttpException('Not deleted', 400);
        }
        return result;
    }

    public async updateOne(query: object, user: UserUpdateDto): Promise<User> {
        return await this.userModel.findOneAndUpdate(query, user).exec();
    }

    public async updateMany(query: object, user: UserUpdateDto): Promise<any> {
        return await this.userModel.updateMany(query, user).exec();
    }


    public async add(newUser: UserCreateDto): Promise<User> {
        const user = await new this.userModel(newUser);
        return await user.save();
    }

    public async addRange(newUsers: UserCreateDto[]): Promise<any> {
        return await this.userModel.collection.insertMany(newUsers);
    }

}

有两个问题我无法处理： 1- 密码字段仍在响应中。我想排除它 2- 响应对象不干净。有很多字段我不想得到。

我期望的回应是：

{ 
isSuccess: true,
message:'ok',
  data: {
    "firstName": "",
    "lastName": "",
    "email": "ali@gel.com",
    "phone": "",
    "userName": "ali@gel.com",
    "avatar": ""
  }
}
