【问题描述】：

我正在尝试将我的 nestjs 应用程序连接到 SQL Server Express，但出现此错误：

ConnectionError: 无法连接到 localhost:1433 - 自签名证书

注意：端口 1433 已打开，我可以通过 SSMS 进行连接：

import  Module  from '@nestjs/common';
import  TypeOrmModule  from '@nestjs/typeorm';
import  AppController  from './app.controller';
import  AppService  from './app.service';

@Module(
  imports: [
    TypeOrmModule.forRoot(
      type: 'mssql',
      host: 'localhost',
      port: 1433,
      username: 'sa',
      password: '<mypassword>',
      database: 'test',
      entities: [__dirname + '/**/*.entity.ts,.js']
    )
  ],
  controllers: [AppController],
  providers: [AppService],
)
export class AppModule 

【参考方案1】：

使用这个 trustServerCertificate: true

@Injectable()
export class TypeOrmConfigService implements TypeOrmOptionsFactory 
  constructor(private configService: ConfigrationService) 

  createTypeOrmOptions(connectionName?: string): TypeOrmModuleOptions | Promise<TypeOrmModuleOptions> 
    return Promise.resolve<TypeOrmModuleOptions>(
      type: 'mssql',
      name: connectionName,
      host: this.configService.dbHost,
      port: this.configService.dbPort,
      username: this.configService.dbUsername,
      password: this.configService.dbPassword,
      database: this.configService.dbName,
      entities: [__dirname + '/**/*.entity.ts,.js'],
      synchronize: true,
      autoLoadEntities: true,
      options: 
        encrypt: true,
      ,
      extra: 
        validateConnection: false,
        trustServerCertificate: true,
      ,
    );
