Unable to set cookie in nestjs, TypeError: Cannot set properties of undefined (setting 'color')

Question

我正在尝试在会话中设置 属性 但未定义。使用 NestJs + Fastify

app.module.ts

import { FastifyAdapter, NestFastifyApplication } from '@nestjs/platform-fastify';
// import fastifyCookie, { FastifyCookieOptions } from 'fastify-cookie'; --this was also not workin

const cookieSession = require( 'cookie-session' );

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter( )
    );

  app.register( cookieSession( { 
    keys: [ 'asdsds' ]
  } ) );

  lines...
}
bootstrap();

users.controller.ts

imports...

export class UsersController {

    constructor( private usersService: UsersService, private authService: AuthService ) { }

    @Get( '/colors/:color' )
    setColor( @Param( 'color' ) color: string, @Session( ) session: any ) {
        // console.log( 'check ', session ); --> UNDEFINED
        session.color = color; --> Error HERE
        // session.set( color );
    }

    @Get( '/colors' ) 
    getColor( @Session( ) session: any ) {
        console.log( 'get session: ', session );
        return session.color;
    }

错误是：

[Nest] 41229  - 13/02/2022, 9:51:06 pm   ERROR [ExceptionsHandler] Cannot set properties of undefined (setting 'color')
TypeError: Cannot set properties of undefined (setting 'color')
    at UsersController.setColor (/home/prabhat/Practice/Nest-Fastify/nestfastify/src/users/users.controller.ts:20:22)

    at processTicksAndRejections (node:internal/process/task_queues:96:5)

我也试过

// app.register(fastifyCookie );
// app.register(fastifySession, {secret: 'a secret with minimum length of 32 characters'});

Answer 1

cookie-session 是一个快速中间件。所以如果它与 fastify 一起使用，你可能会得到 req.raw.session 作为 cookie。

fastify-cookie 是 cookie 支持的 fastify 特定包，但不是直接的会话，所以你需要使用 req.cookie 或制作一个 @Cookie()装饰器

@fastify/session是fastify中session支持的包。通过将 @fastify/session 与 fastify-cookie 一起使用，您将可以访问 req.session 和 req.cookie

对我有用的是fastify-secure-session包，提到here

现在我的 main.ts 看起来像：

imports..
import secureSession from 'fastify-secure-session';

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter( )
    );

  app.register(secureSession, {
    secret: 'averylogphrasebiggerthanthirtytwochars',
    salt: 'mq9hDxBVDbspDR6n',
  });

  lines..
}
bootstrap();

而app.controller.ts是：

imports..
import * as secureSession from 'fastify-secure-session'

@Controller( 'auth' )
@MongooseClassSerializerInterceptor( UserDto )
export class UsersController {

    constructor( private usersService: UsersService, private authService: AuthService ) { }

    @Get( '/colors/:color' )
    setColor( @Param( 'color' ) color: string, @Session( ) session: secureSession.Session ) {
        console.log( 'check ', session );
        // session.color = color;
        session.set('color', color)
    }

    @Get( '/colors' ) 
    getColor( @Session( ) session: secureSession.Session ) {
        console.log( 'get session: ', session );
        // return session.color;
        return session.get( 'color' );
    }
   
}

有了这个我就可以在带有 Fastify 的 NestJs 中设置 cookie。

仍然想知道为什么以前的方法对我不起作用，正如 @Jay 在他们的回答中提到的那样。
