NestJS jwt-passport身份验证 [英] NestJS jwt-passport Authentication

问题描述

我想实现一个分布式身份验证库，以便在多个项目中使用它.该库应实现JWT身份验证方法.代码如下:

I want to implement a distributed authentication library to use it on several projects. The library should implement JWT authentication method. The code is as follows:

jwt.strategy.ts

import {ExtractJwt, Strategy} from 'passport-jwt';
import {PassportStrategy} from '@nestjs/passport';
import {Injectable} from '@nestjs/common';
import {JwtPayload, User} from './interfaces';
import {ConfigService} from "./config.service";

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
  constructor(private readonly configService: ConfigService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      secretOrKey: configService.get('secretOrPrivateKey'),
    });
  }

  async validate(payload: JwtPayload): Promise<User> {
     return {
      uuid: payload.uuid,
      email: payload.email,
    }
  }
}

jwt.auth.module.ts:

import {Module, DynamicModule} from '@nestjs/common';
import {JwtModule} from '@nestjs/jwt';
import {JwtStrategy} from './jwt.strategy';
import {PassportModule} from '@nestjs/passport';
import {ConfigService} from "./config.service";
import {JwtOptions} from "./interfaces/jwt.options";

@Module({
})

export class JwtAuthModule {
  static forRoot(jwtOptions): DynamicModule {
    return {
      module: JwtAuthModule,
      imports: [
        // JwtModule.register(jwtOptions),
        // PassportModule.register({defaultStrategy: 'jwt'}),
      ],
      providers: [
        JwtStrategy,
        {
          provide: ConfigService,
          useValue: new ConfigService(jwtOptions),
        }
      ],
      exports: [ConfigService, JwtStrategy]
    };
  }
}

并且我已经将其导入到我的app.module.ts中:

and I have imported this in my app.module.ts:

import { Module, NestModule, HttpModule } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { environment } from './environments';
import { AuthModule } from './auth/auth.module';
import { PermissionModule } from './permission/permission.module';
import {JwtAuthModule} from '@pe/nest-kit';
import {JwtModule} from '@nestjs/jwt';
import {PassportModule} from '@nestjs/passport';

@Module({
  imports: [
    JwtModule.register(environment.jwtOptions),
    PassportModule.register({defaultStrategy: 'jwt'}),
    JwtAuthModule.forRoot(environment.jwtOptions),
    HttpModule,
    AuthModule,
    PermissionModule,
    MongooseModule.forRoot(environment.mongodb),
  ],
})
export class ApplicationModule implements NestModule {
  configure() {
  }
}

但是，每次我尝试打开项目url时，都会收到错误消息:

however, each time I try to open project url, I'm getting an error:

我在做什么错了?

推荐答案

尝试将JwtStrategy作为提供程序添加到模块中:

Try to add the JwtStrategy as a provider in your module :

@Module({
  imports: [
   ....
  ],
  providers: [JwtStrategy],
})

然后重试！
