UseFilters
UseFilters 作用于控制器：
import { Controller, UseFilters } from '@nestjs/common';
@Controller('user')
@UseFilters(MyHttpExceptionFilter)
export class UserController {
...
}
如果需要全局过滤器：
import { NestFactory } from '@nestjs/core';
import { NestExpressApplication } from '@nestjs/platform-express';
import { ConfigService } from '@nestjs/config';
import { AppModule } from './app.module';
import { text } from 'body-parser';
import * as xmlparser from 'express-xml-bodyparser';
import * as cookieParser from 'cookie-parser';
import { join } from 'path';
import { GlobalExceptionFilter } from './common/filter/global.filter';
async function bootstrap() {
const app = await NestFactory.create<NestExpressApplication>(AppModule);
app.enableCors();
app.use(cookieParser());
app.use(text());
app.use(xmlparser());
app.useStaticAssets(join(process.cwd(), 'public'));
app.useGlobalFilters(new GlobalExceptionFilter());
const configService = app.get(ConfigService);
process.title = configService.get<string>('TITLE');
const PORT = configService.get<number>('PORT');
await app.listen(PORT);
console.log(`server running at port：${PORT}`);
}
bootstrap();
