NestJS 9.4.0 在创建 Fastify 应用程序时崩溃

Question

我为 NestJS 9.4.0 应用程序安装了 Throttler 来保护它，但是当我使用 NestFastify 时它给了我一个错误，有人知道它应该是什么样子吗？ A需要使用Fastify进行CSRF等后续安全。很长一段时间以来，我一直在努力解决这个问题，我什至决定在 ChatGPT 上询问，它表明一切都很好。我会补充说，只有在输入适当的路线后才会出现错误。

作品主代码：

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ConfigService } from '@nestjs/config';
import {
  FastifyAdapter,
  NestFastifyApplication,
} from '@nestjs/platform-fastify';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  const configService = app.get(ConfigService);
  const port = configService.get<string>('PORT', '');

  // Throttler - Protection
  app.enableCors({
    origin: '*',
    methods: 'GET,HEAD,PUT,PATCH,POST,DELETE',
    allowedHeaders: 'Content-Type,Authorization',
    credentials: true,
  });

  await app.listen(port);
}
bootstrap();

主代码不起作用：

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ConfigService } from '@nestjs/config';
import {
  FastifyAdapter,
  NestFastifyApplication,
} from '@nestjs/platform-fastify';

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter(),
  );
  const configService = app.get(ConfigService);
  const port = configService.get<string>('PORT', '');

  // Throttler - Protection
  app.enableCors({
    origin: '*',
    methods: 'GET,HEAD,PUT,PATCH,POST,DELETE',
    allowedHeaders: 'Content-Type,Authorization',
    credentials: true,
  });

  await app.listen(port);
}
bootstrap();

应用程序模块代码：

@Module({
  imports: [
    ConfigModule.forRoot({
      ignoreEnvFile: !!process.env.CI,
      envFilePath: join(__dirname, '..', '.env'),
      validationSchema: envSchema,
    }),
    TypeOrmModule.forRootAsync({
      useClass: TypeOrmConfigService,
    }),
    // Throttler - Protection
    ThrottlerModule.forRoot({
      ttl: Number(process.env.THROTTLER_TTL),
      limit: Number(process.env.THROTTLER_LIMIT),
      storage: {
        store: 'redis',
        options: {
          url: `redis://${process.env.REDIS_HOST}:${process.env.REDIS_PORT}`,
        },
      },
    }),
    PassportModule.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService) => ({
        defaultStrategy: configService.get('jwt.defaultStrategy'),
      }),
    }),
    AuthModule,
    UsersModule,
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

错误：

Answer 1

Passport 并不always 与 Fastify 一起工作，尤其是与 OAuth 特定策略。为了解决这个问题，您可以使用方法和属性装饰

FastifyReply

和

FastifyRequest

对象以使护照工作。以下代码片段可用于相应地修改和装饰对象：

const fastifyInstance: FastifyInstance = app.getHttpAdapter().getInstance()
  fastifyInstance
    .addHook('onRequest', async (req, res) => {
      req.socket['encrypted'] = process.env.NODE_ENV === 'production'
    })
    .decorateReply('setHeader', function (name: string, value: unknown) {
      this.header(name, value)
    })
    .decorateReply('end', function () {
      this.send('')
    })

在您致电

main.ts

之前将此添加到您的

app.listen()

，它应该可以工作
