While trying to access my login route in the app.controller.ts of my rest api built with Nestjs and Prisma, I encountered a 401 error response. I have been closely following the official documentation provided by Nestjs on authentication (https://docs.nestjs.com/security/authentication).
Below is the snippet from ./app.controller.ts :
import { LocalAuthGuard } from './auth/local-auth.guards';
@Controller()
export class AppController {
constructor(
private readonly appService: AppService,
private readonly authService: AuthService,
) {}
@UseGuards(LocalAuthGuard)
@Post('auth/login')
async login(@Request() req) {
return req.user;
}
The contents of ./auth/local.strategy.ts are as follows:
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();
}
async validate(username: string, password: string): Promise<any> {
const user = await this.authService.validateUser(username, password);
console.log('validation');
if (!user) {
throw new UnauthorizedException();
}
return user;
}
}
And finally, here's the content of ./auth/local-auth.guards.ts:
import { Injectable } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';
@Injectable()
export class LocalAuthGuard extends AuthGuard('local') {}
Based on my understanding, the use of @UseGuards(LocalAuthGuard) should grant access to the /auth/login function only if the
validate(username: string, password: string)Thank you for taking the time to read this, any assistance offered will be greatly appreciated.
