반드시 cookie-parser 설치할것

1. 인터넷에 많이 퍼져있는 방법

1. fromAuthHeaderAsBearerToken 사용

import { Injectable } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
  constructor() {
    super({
      //Request에서 JWT 토큰을 추출하는 방법을 설정 -> Authorization에서 Bearer Token에 JWT 토큰을 담아 전송해야한다.
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      //true로 설정하면 Passport에 토큰 검증을 위임하지 않고 직접 검증, false는 Passport에 검증 위임
      ignoreExpiration: false,
      //검증 비밀 값(유출 주의)
      secretOrKey: process.env.JWT_ACCESS_TOKEN_SECRET,
      // passReqToCallback: true,
    });
  }

  /**
   * @description 클라이언트가 전송한 Jwt 토큰 정보
   *
   * @param payload 토큰 전송 내용
   */
  async validate(payload: any): Promise<any> {
    return { email: payload.email };
  }
}

2. ExtractJwt.fromExtractors 사용

import { Injectable } from '@nestjs/common';
import { ConfigService } from '@nestjs/config';
import { PassportStrategy } from '@nestjs/passport';
import { Request } from 'express';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { AuthService } from '../auth.service';
@Injectable()
export class JwtRefreshStrategy extends PassportStrategy(
  Strategy,
  'jwt-refresh-token',
) {
  constructor(
    private authService: AuthService,
    private configService: ConfigService,
  ) {
    super({
      jwtFromRequest: ExtractJwt.fromExtractors([
        (request: any) => {
          return request?.cookies['Refresh'].split(' ')[1];
        },
      ]),
      // 공식문서
      // jwtFromRequest: ExtractJwt.fromExtractors([
      //   (request: any) => {
      //     let token = null;
      //     if (request && request.cookies) {
      //       token = request.cookies['Refresh'].split(' ')[1];
      //     }
      //     return token;
      //   },
      // ]),
      ignoreExpiration: false,
      secretOrKey: configService.get('JWT_REFRESH_TOKEN_SECRET'),
      passReqToCallback: true,
    });
  }

  async validate(req: any, payload: any): Promise<any> {
    const refreshToken = req.cookies['Refresh'].split(' ')[1];
    return this.authService.getUserIfRefreshTokenMatches(
      refreshToken,
      payload.email,
    );
  }
}

2. 공식문서

http://www.passportjs.org/packages/passport-jwt/

위 코드 주석에 나와있다.

import { Injectable } from '@nestjs/common';
import { ConfigService } from '@nestjs/config';
import { PassportStrategy } from '@nestjs/passport';
import { Request } from 'express';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { AuthService } from '../auth.service';
@Injectable()
export class JwtRefreshStrategy extends PassportStrategy(
  Strategy,
  'jwt-refresh-token',
) {
  constructor(
    private authService: AuthService,
    private configService: ConfigService,
  ) {
    super({
      // 공식문서
      jwtFromRequest: ExtractJwt.fromExtractors([
        (request: any) => {
          let token = null;
          if (request && request.cookies) {
            token = request.cookies['Refresh'].split(' ')[1];
          }
          return token;
        },
      ]),
      ignoreExpiration: false,
      secretOrKey: configService.get('JWT_REFRESH_TOKEN_SECRET'),
      passReqToCallback: true,
    });
  }

  async validate(req: any, payload: any): Promise<any> {
    const refreshToken = req.cookies['Refresh'].split(' ')[1];
    return this.authService.getUserIfRefreshTokenMatches(
      refreshToken,
      payload.email,
    );
  }
}
