如何使用passport和nestjs将api密钥作为查询字符串传递给请求url

// app.module.ts
import { Module } from '@nestjs/common';
import { PassportModule } from '@nestjs/passport';
import { AuthController } from './auth.controller';
import { AuthGuard } from './auth.guard';

@Module({
  imports: [PassportModule],
  controllers: [AuthController],
  providers: [AuthGuard],
})
export class AppModule {}

// auth.guard.ts
import { Injectable } from '@nestjs/common';
import { AuthGuard as NestAuthGuard } from '@nestjs/passport';

@Injectable()
export class AuthGuard extends NestAuthGuard('apiKey') {
  canActivate() {
    return super.canActivate();
  }

  handleRequest(err, user, info) {
    if (err || !user) {
      throw err || new UnauthorizedException();
    }
    return user;
  }
}

// auth.controller.ts
import { Controller, Get, UseGuards, Req } from '@nestjs/common';
import { AuthGuard } from './auth.guard';

@Controller('api')
export class AuthController {
  @Get('protected')
  @UseGuards(AuthGuard)
  protectedRoute(@Req() req) {
    const apiKey = req.query.apiKey; // 从查询字符串中获取API密钥
    // 将API密钥作为查询字符串传递给请求URL
    const url = `https://example.com/api?apiKey=${apiKey}`;
    // 发送请求并处理响应
    // ...
  }
}
