我无法从装饰器嵌套的请求中获取用户,请帮助我。 中间件很好,它可以按令牌查找用户并在请求中保存用户 我的中间件:

import { Injectable, NestMiddleware, HttpStatus } from '@nestjs/common';
import { HttpException } from '@nestjs/common/exceptions/http.exception';
import { Request, Response } from 'express';
import { AuthenticationService } from '../modules/authentication-v1/authentication.service';

@Injectable()
export class AuthenticationMiddleware implements NestMiddleware {
    constructor(
        private readonly authenticationService : AuthenticationService
    ) {
    }
    async use(req: Request, res: Response, next: Function) {
        let token = req.headers;

        if(!token) {
            throw new HttpException('token is required', 401);
        }

        if (!token.match(/Bearer\s(\S+)/)) {
            throw new HttpException('Unsupported token', 401);
        }
        const [ tokenType, tokenValue ] = token.split(' ');
        try {
            const result = await this.authenticationService.getAccessToken(tokenValue);
            req.user = result;
            next();
        } catch (e) {
            throw new HttpException(e.message, 401);
        }
    }
}

但是这里请求没有属性用户,我也不知道为什么 用户装饰器:

export const User = createParamDecorator((data: any, req) => {
    return req.user; // but here user undefined
});

应用程序模块:

export class AppModule {
    configure(consumer: MiddlewareConsumer) {
        consumer
            .apply(AuthenticationMiddleware)
            .forRoutes({ path: 'auto-reports-v1', method: RequestMethod.GET });
    }
}

路由方法:

@UseInterceptors(LoggingInterceptor)
@Controller('auto-reports-v1')
@ApiTags('auto-reports-v1')
export class AutoReportsController {
    constructor(private readonly autoReportsService: AutoReportsService) {}

    @Get()
    async findAll(
        @Query() filter: any,
        @User() user: any): Promise<Paginated> {
        return this.autoReportsService.findPaginatedByFilter(filter, user);
    }
}

在带有Fastify的NestJS中,中间件将值附加到req.raw。这是因为中间件在请求被FastifyRequest对象包装之前运行,因此所有值附件都被附加到IncomingRequest对象(与Express Request对象相同)。然后,Fastify将IncomingRequest包装在其自己的FastifyRequest对象中,并通过IncomingRequest公开req.raw,这意味着您要查找的用户位于req.raw.user而不是{{ 1}}。如果您希望Express和Fastify拥有相同的功能,建议您改用Guard。
