NextResponse

NextResponse 扩展了 Web Response API

new NextResponse()

new NextResponse(body, options) 构造函数创建了一个新的 Response 对象。 body 可以是:

• Blob
• Buffer
• FormData
• ReadableStream
• URLSearchParams
• String

import { NextResponse } from 'next/server'

export function middleware(request: NextRequest) {
    return new NextResponse('Hello world', {status: 200})
}

NextResponse.json()

返回json格式的响应

import { NextResponse } from 'next/server'
 
export async function middleware(request) {
  return NextResponse.json({ error: 'Internal Server Error' }, { status: 500 })
}

NextResponse.redirect()

重定向到指定url

import { NextResponse } from 'next/server'
 
export async function middleware(request) {
    return NextResponse.redirect(new URL('/new', request.url))
}

NextResponse.rewrite()

重写请求

import { NextResponse } from 'next/server'
 
 import { NextResponse } from 'next/server'
 
export async function middleware(request) {
    return NextResponse.rewrite(new URL('/proxy', request.url))
}

NextResponse.next()

继续执行下一个中间件，同时返回响应

import { NextResponse } from 'next/server'
 

export async function GET(request) {
    const response = NextResponse.next()
    response.cookies.set('show-banner', 'false')
    return response;
}
