通过`passport-jwt`与Auth0进行NestJS认证

Question

我正在尝试创建一个使用Auth0进行身份验证的NestJS项目，使用passport-jwt库（与@nestjs/passport一起使用），但我无法让它工作。我不确定我哪里出错了。我一遍又一遍地阅读文档，但仍然找不到问题。

码

/src/auth/jwt.strategy.ts

import { Injectable, UnauthorizedException } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { passportJwtSecret } from 'jwks-rsa';
import { xor } from 'lodash';
import { JwtPayload } from './interfaces/jwt-payload.interface';

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor() {
    super({
      secretOrKeyProvider: passportJwtSecret({
        cache: true,
        rateLimit: true,
        jwksRequestsPerMinute: 5,
        jwksUri: `https://${process.env.AUTH0_DOMAIN}/.well-known/jwks.json`,
      }),

      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      audience: 'http://localhost:3000',
      issuer: `https://${process.env.AUTH0_DOMAIN}/`,
    });
  }

  validate(payload: JwtPayload) {
    if (
      xor(payload.scope.split(' '), ['openid', 'profile', 'email']).length > 0
    ) {
      throw new UnauthorizedException(
        'JWT does not possess the requires scope (`openid profile email`).',
      );
    }
  }
}

/src/auth/interfaces/jwt-payload.interface

/* Doesn't do much, not really relevant */
import { JsonObject } from '../../common/interfaces/json-object.interface';

export interface JwtPayload extends JsonObject {
  /** Issuer (who created and signed this token) */
  iss?: string;
  /** Subject (whom the token refers to) */
  sub?: string;
  /** Audience (who or what the token is intended for) */
  aud?: string[];
  /** Issued at (seconds since Unix epoch) */
  iat?: number;
  /** Expiration time (seconds since Unix epoch) */
  exp?: number;
  /** Authorization party (the party to which this token was issued) */
  azp?: string;
  /** Token scope (what the token has access to) */
  scope?: string;
}

/src/auth/auth.module.ts

import { Module } from '@nestjs/common';
import { JwtStrategy } from './jwt.strategy';
import { PassportModule } from '@nestjs/passport';

@Module({
  imports: [PassportModule.register({ defaultStrategy: 'jwt' })],
  providers: [JwtStrategy],
  exports: [JwtStrategy],
})
export class AuthModule {}

/src/app.module.ts

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { AuthModule } from './auth/auth.module';

@Module({
  imports: [AuthModule],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

/src/app.controller.ts

import { Controller, Get, UseGuards } from '@nestjs/common';
import { AppService } from './app.service';
import { AuthGuard } from '@nestjs/passport';

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @Get()
  getHello(): string {
    return this.appService.getHello();
  }

  @Get('protected')
  @UseGuards(AuthGuard())
  getProtected(): string {
    return 'This route is protected';
  }
}

使用有效的承载令牌向localhost:3000/protected获取请求会导致错误{"statusCode":401,"error":"Unauthorized"}。

UPDATE

好吧，在将bodge-y包装函数放在任何地方之后，我想我已经找到了问题的根源：每次运行secretOrKeyProvider函数时，done都会以令人难以置信的熟悉（对我来说）错误SSL Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE进行调用。这是因为我学校的烦人的防火墙/ CA，这是我生命中最烦人的事情。到目前为止，我发现解决这个问题的唯一方法是做危险的NODE_TLS_REJECT_UNAUTHORIZED=0（我尝试过使用NODE_EXTRA_CA_CERTS，但到目前为止我失败了）。由于某种原因（虽然可能是一个好的）我的解决方法在这种情况下不起作用。

UPDATE

我设法让NODE_EXTRA_CA_CERTS工作，让我狂喜地尖叫起来。

所有我必须做的（一旦我停止得到UNABLE_TO_VERIFY_LEAF_SIGNATURE错误，我所要做的就是返回payload，如果它是有效的。

/src/auth/jwt.strategy.ts

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor() {
    super({
      secretOrKeyProvider: passportJwtSecret({
        cache: true,
        rateLimit: true,
        jwksRequestsPerMinute: 5,
        jwksUri: `https://${process.env.AUTH0_DOMAIN}/.well-known/jwks.json`,
      }),

      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      audience: 'http://localhost:3000',
      issuer: `https://${process.env.AUTH0_DOMAIN}/`,
    });
  }

  validate(payload: JwtPayload): JwtPayload {
    if (
      xor(payload.scope.split(' '), ['openid', 'profile', 'email']).length > 0
    ) {
      throw new UnauthorizedException(
        'JWT does not possess the requires scope (`openid profile email`).',
      );
    }
    return payload;
  }
}
