NestJS -如何处理非api应用程序中的全局异常

import { Module } from '@nestjs/common';
import { APP_FILTER } from '@nestjs/core';
import { ExceptionFilter } from './exception.filter';
import { HttpExceptionFilter } from './http-exception.filter';

@Module({
  providers: [
    {
      provide: APP_FILTER,
      useClass: ExceptionFilter,
    },
    {
      provide: APP_FILTER,
      useClass: HttpExceptionFilter,
    },
  ],
})
export class AppModule {}

import { ExceptionFilter, Catch, ArgumentsHost } from '@nestjs/common';

@Catch()
export class ExceptionFilter implements ExceptionFilter {
  catch(exception: any, host: ArgumentsHost) {
    // 处理异常逻辑
    console.error('An exception occurred:', exception);
    // 这里可以执行额外的逻辑，例如记录日志、发送通知等
  }
}

import { ExceptionFilter, Catch, HttpException, ArgumentsHost } from '@nestjs/common';

@Catch(HttpException)
export class HttpExceptionFilter implements ExceptionFilter {
  catch(exception: HttpException, host: ArgumentsHost) {
    const ctx = host.switchToHttp();
    const response = ctx.getResponse();
    const status = exception.getStatus();

    response.status(status).json({
      statusCode: status,
      message: exception.message,
    });
  }
}
