Nest.js passport-local email 使う

passportのLocalStrategyのデフォルト値は、usernameとpasswordなので、emailに変更する。変えないと、401が返ってくる。

js
import { Strategy } from 'passport-local';
import { PassportStrategy } from '@nestjs/passport';
import { Injectable, UnauthorizedException } from '@nestjs/common';
import { AuthService } from './auth.service';

@Injectable()
export class LocalStrategy extends PassportStrategy(Strategy) {
  constructor(private authService: AuthService) {
    super({ usernameField: 'email' }); // 👈 追記
  }

  async validate(email: string, password: string): Promise<any> {
    const user = await this.authService.validateUser(email, password);
    if (!user) {
      throw new UnauthorizedException();
    }
    return user;
  }
}
