在nest.js中设置请求头部大小限制

import { MiddlewareFunction, NestMiddleware } from '@nestjs/common';
import { NextFunction, Request, Response } from 'express';

export class RequestHeaderSizeLimitMiddleware implements NestMiddleware {
  resolve(): MiddlewareFunction {
    return (req: Request, res: Response, next: NextFunction) => {
      // 设置请求头部大小限制为 1MB
      express.json({ limit: '1mb' })(req, res, next);
    };
  }
}

import { MiddlewareConsumer, Module, NestModule } from '@nestjs/common';
import { RequestHeaderSizeLimitMiddleware } from './request-header-size-limit.middleware';

@Module({})
export class AppModule implements NestModule {
  configure(consumer: MiddlewareConsumer) {
    consumer.apply(RequestHeaderSizeLimitMiddleware).forRoutes('*');
  }
}
