431：请求标题字段太大错误

Question

我正在创建一个将Nestjs用于后端部分并为前端部分做出反应的项目。我想添加用户，但是有一个错误的错误。当我使用Postman提出请求时，它可以正常工作，但是当我通过正面尝试时，它会发送 431 错误。我正在使用Redux/Toolkit发送请求。我正在使用http：// localhost：3001/。我尝试添加一个“ start”：“ nest start--max-http-header-size = 80000”后端和前端，但这对我没有帮助。附加了一个请求 - 响应屏幕：

frontend请求

import { createApi, fetchBaseQuery } from "@reduxjs/toolkit/query/react";
import { CreateUserRequest } from "../dto/create-user-request.dto";
import { User } from "../models/User";

export const usersApi = createApi({
  reducerPath: "usersApi",
  baseQuery: fetchBaseQuery({
    baseUrl: "/users",
  }),
  endpoints: (build) => ({
    createUser: build.mutation<User, CreateUserRequest>({
      query: (createUserRequest) => ({
        url: "/",
        method: "POST",
        body: createUserRequest,
      }),
    }),
  }),
});


export const { useCreateUserMutation } = usersApi;

后端main.ts

import { ValidationPipe } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';


async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.enableCors();
  app.useGlobalPipes(new ValidationPipe())
  await app.listen(3000);
}
bootstrap();

users.controller.ts

import { Body, Controller, Post } from '@nestjs/common';
import { CreateUserRequest } from './dto/request/create-user-request.dto';
import { UserResponse } from './dto/response/user-response.dto';
import { UsersService } from './users.service';

@Controller('users')
export class UsersController {

  constructor(private readonly usersService: UsersService) { }

  @Post()
  async createUser(
    @Body() createUserRequest: CreateUserRequest

  ): Promise<UserResponse> {
    return this.usersService.createUser(createUserRequest)
  }
}
