我正在使用 NestJs、Fastify、Mercurius 和联合服务创建一个 GraphQL 应用程序。

我创建了两个服务（用户、餐厅），但是在创建网关时，它只显示一个服务的架构，而不是两个。我试图颠倒顺序，似乎它只需要顶部的那个，这意味着当我把用户 URL 放在第一位时，它只需要用户模式，餐厅也是如此。下面是网关和两个服务的声明：

网关

import { Module } from '@nestjs/common';

import { AppController } from './app.controller';
import { AppService } from './app.service';
import { GraphQLModule } from '@nestjs/graphql';
import {
  MercuriusGatewayDriver,
  MercuriusGatewayDriverConfig,
} from '@nestjs/mercurius';

@Module({
  imports: [
    GraphQLModule.forRoot<MercuriusGatewayDriverConfig>({
      driver: MercuriusGatewayDriver,
      gateway: {
        services: [
          {
            name: 'users',
            url: 'http://localhost:3001/graphql',
            mandatory: true,
          },
          {
            name: 'restaurants',
            url: 'http://localhost:3002/graphql',
            mandatory: true,
          },
        ],
        pollingInterval: 5000,
      },
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

用户

import { AppController } from './app.controller';
import { AppService } from './app.service';
import { UserModule } from '../user/user.module';
import { JwtModule } from '@nestjs/jwt';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { AddressModule } from '../address/address.module';
import { GraphQLModule } from '@nestjs/graphql';
import {
  MercuriusFederationDriver,
  MercuriusFederationDriverConfig,
} from '@nestjs/mercurius';

@Module({
  imports: [
    GraphQLModule.forRoot<MercuriusFederationDriverConfig>({
      driver: MercuriusFederationDriver,
      autoSchemaFile: true,
      federationMetadata: true,
    }),
    UserModule,
    AddressModule,
    JwtModule.registerAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        secret: configService.get('SECRET_JWT_ACCESS_KEY'),
      }),
      inject: [ConfigService],
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

餐厅

import { ConfigModule, ConfigService } from '@nestjs/config';
import { JwtModule } from '@nestjs/jwt';

import { AppController } from './app.controller';
import { AppService } from './app.service';
import { RestaurantModule } from '../restaurant/restaurant.module';
import { RestauAddressModule } from '../restau-address/restau-address.module';
import { GraphQLModule } from '@nestjs/graphql';
import {
  MercuriusFederationDriver,
  MercuriusFederationDriverConfig,
} from '@nestjs/mercurius';

@Module({
  imports: [
    GraphQLModule.forRoot<MercuriusFederationDriverConfig>({
      driver: MercuriusFederationDriver,
      autoSchemaFile: true,
      federationMetadata: true,
    }),
    JwtModule.registerAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        secret: configService.get('SECRET_JWT_ACCESS_KEY'),
      }),
      inject: [ConfigService],
    }),
    RestaurantModule,
    RestauAddressModule,
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

所有单独工作正常。
