HTTPS
要创建使用 HTTPS 协议的应用程序，需在传递给 NestFactory 类的 create() 方法的配置对象中设置 httpsOptions 属性：
const httpsOptions = {
key: fs.readFileSync('./secrets/private-key.pem'),
cert: fs.readFileSync('./secrets/public-certificate.pem'),
};
const app = await NestFactory.create(AppModule, {
httpsOptions,
});
await app.listen(process.env.PORT ?? 3000);
如果使用 FastifyAdapter，则按如下方式创建应用程序：
const app = await NestFactory.create<NestFastifyApplication>(
AppModule,
new FastifyAdapter({ https: httpsOptions })
);
同时运行多个服务器
以下示例展示了如何实例化一个 Nest 应用程序，使其能够同时监听多个端口（例如非 HTTPS 端口和 HTTPS 端口）。
const httpsOptions = {
key: fs.readFileSync('./secrets/private-key.pem'),
cert: fs.readFileSync('./secrets/public-certificate.pem'),
};
const server = express();
const app = await NestFactory.create(AppModule, new ExpressAdapter(server));
await app.init();
const httpServer = http.createServer(server).listen(3000);
const httpsServer = https.createServer(httpsOptions, server).listen(443);
由于我们自行调用了 http.createServer/https.createServer，NestJS 在调用 app.close 或终止信号时不会关闭这些服务器。我们需要自行处理：
@Injectable()
export class ShutdownObserver implements OnApplicationShutdown {
private httpServers: http.Server[] = [];
public addHttpServer(server: http.Server): void {
this.httpServers.push(server);
}
public async onApplicationShutdown(): Promise<void> {
await Promise.all(
this.httpServers.map(
(server) =>
new Promise((resolve, reject) => {
server.close((error) => {
if (error) {
reject(error);
} else {
resolve(null);
}
});
})
)
);
}
}
const shutdownObserver = app.get(ShutdownObserver);
shutdownObserver.addHttpServer(httpServer);
shutdownObserver.addHttpServer(httpsServer);
