nestjs:当我使用 GraphQL 时如何抛出 AuthenticationError

Question

我编写了 GqlAuthGuard 模块，但它总是在 JWT 过期或非法时抛出 UnauthorizedException。它将导致堆栈跟踪错误。

我想抛出 AuthenticationError(来自 apollo-server-express)。

我该怎么做？

import { Injectable, ExecutionContext } from '@nestjs/common'
import { AuthGuard } from '@nestjs/passport'
import { GqlExecutionContext } from '@nestjs/graphql'

@Injectable()
export class GqlAuthGuard extends AuthGuard('jwt') {
  public getRequest(context: ExecutionContext) {
    const ctx = GqlExecutionContext.create(context)
    return ctx.getContext().req
  }
}

GraphQL Authorization Error

Answer 1

我不得不修改 Jay McDoniel 提出的解决方案:

import { Injectable, ExecutionContext } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';
import { GqlExecutionContext } from '@nestjs/graphql';
import { AuthenticationError } from 'apollo-server-express';

@Injectable()
export class GqlAuthGuard extends AuthGuard('jwt') {
  async canActivate(context: ExecutionContext): Promise<boolean> {
    try {
      return (await super.canActivate(context)) as boolean;
    } catch (e) {
      throw new AuthenticationError('You are not logged-in.');
    }
  }

  getRequest(context: ExecutionContext) {
    const ctx = GqlExecutionContext.create(context);
    return ctx.getContext().req;
  }
}
