如何使用fastify在NestJS中提供静态文件？我似乎找不到最近的任何适当设置的例子。我的main.ts设置如下：
main.ts
// This must be the first thing imported in the app
import 'src/tracing';
import * as winston from 'winston';
import fastifyStatic, { FastifyStaticOptions } from '@fastify/static';
import { NestFactory } from '@nestjs/core';
import {
FastifyAdapter,
NestFastifyApplication,
} from '@nestjs/platform-fastify';
import { path } from 'app-root-path';
import { WinstonModule } from 'nest-winston';
import { doc } from 'prettier';
import { AppModule } from 'src/app.module';
import join = doc.builders.join;
async function bootstrap() {
const app = await NestFactory.create<NestFastifyApplication>(
AppModule,
new FastifyAdapter(),
{
logger: WinstonModule.createLogger({
format: winston.format.combine(
winston.format.timestamp(),
winston.format.json(),
),
transports: [new winston.transports.Console()],
}),
rawBody: true,
},
);
await app.register(require('@fastify/static'), {
root: require('app-root-path').resolve('/client'),
prefix: '/client/', // optional: default '/'
});
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-ignore
app.get('/another/path', function (req, reply) {
reply.sendFile('index.html');
});
app.enableShutdownHooks(); // terminus needs this to listen for SIGTERM/SIGKILL
await app.listen(3002, '0.0.0.0');
console.log(`Application is running on: ${await app.getUrl()}`);
}
bootstrap();我试图提供的静态文件是client/index.html。
然而，当我运行我的应用程序时，我会得到以下错误：Nest could not find /another/path element (this provider does not exist in the current context)。
我也尝试过设置我的app.module.ts模块如下：
app.module.ts
@Module({
imports: [
...configModules,
...domainModules,
...libraryModules,
ServeStaticModule.forRoot({
rootPath: require('app-root-path').resolve('/client'),
renderPath: '/client/*',
}),
],
controllers: [AppController],
providers: [AppService],
})这将导致以下错误：
/Users/ewu/Desktop/Projects/janus/node_modules/@nestjs/platform-fastify/node_modules/fastify/lib/route.js:286
throw new FST_ERR_DUPLICATED_ROUTE(opts.method, opts.url)
^
FastifyError: Method 'HEAD' already declared for route '/'

at fastifyStatic (/Users/ewu/Desktop/Projects/janus/node_modules/@fastify/static/index.js:370:17)以下是相关的软件包及其版本：
"@nestjs/serve-static": "^3.0.0",
"fastify-static": "^4.7.0",
"fastify": "^4.8.1",
"@nestjs/platform-fastify": "^9.1.2",
"@fastify/static": "^6.0.0",我正在使用Nest的9.0.0版本和Node的16.15.0版本。

您很可能在@Controller() (很可能是您的AppController)下有一个GET /，它已经绑定了GET /路由。Fastify不允许将两个处理程序绑定到同一条路由。因此，您需要更改@Get()以具有与其关联的某种路由，将ServeStaticModule更改为具有不同的服务路由，或者使用全局前缀来修改其余的服务器路由(我相信这会使服务器静态模块不受影响)。
