使用 AuthGuard 登录请求始终为 401 Unauthorized

Question

我一直在关注 this tutorial 并尝试将其转换为 GraphQL。我正在尝试实施 NestJS + GraphQL + Passport + Express-Session 解决方案，但我遇到了 AuthGuard 的问题。遗憾的是，网上关于此的信息很少。我的 AuthGuard 看起来像这样

import { ExecutionContext, Injectable } from '@nestjs/common';
import { ExecutionContextHost } from '@nestjs/core/helpers/execution-context-host';
import { GqlExecutionContext } from '@nestjs/graphql';
import { AuthGuard } from '@nestjs/passport';

@Injectable()
export class LocalGuard extends AuthGuard('local') {
  async canActivate(context: ExecutionContext): Promise<boolean> {
    const ctx = GqlExecutionContext.create(context);
    const { req } = ctx.getContext();
    const result = (await super.canActivate(
      new ExecutionContextHost([req]),
    )) as boolean;
    console.log(result);
    await super.logIn(req);
    return result;
  }
}

不幸的是，我在尝试登录请求时总是收到 Unauthorized 响应。我认为问题出在我的 super.canActivate 电话上。

更新：这是我的 AuthGuard 实现，它终于起作用了。覆盖 getRequest 并将我的输入添加到正文可以解决问题。

import { ExecutionContext, Injectable } from '@nestjs/common';
import { GqlExecutionContext } from '@nestjs/graphql';
import { AuthGuard } from '@nestjs/passport';
@Injectable()
export class LocalGuard extends AuthGuard('local') {
  async canActivate(context: ExecutionContext): Promise<boolean> {
    const result = (await super.canActivate(context)) as boolean;
    const ctx = GqlExecutionContext.create(context);
    const { req } = ctx.getContext();
    await super.logIn(req);
    return result;
  }

  getRequest(context: ExecutionContext) {
    const ctx = GqlExecutionContext.create(context);
    const gqlReq = ctx.getContext().req;
    if (gqlReq) {
      const { authCredentialsInput } = ctx.getArgs();
      gqlReq.body = authCredentialsInput;
      return gqlReq;
    }
  }
}

使用 AuthGuard 登录请求始终为 401 Unauthorized

Login request is always 401 Unauthorized with AuthGuard

graphql

nestjs

passport.js

express-session

auth-guard
