Fetching Next.js API Route in the app directory gives 404 Not Found
问题
我在处理 Next.js 13 的 app 路由时遇到了问题。每当我尝试从 Postman 等工具访问时，它总是返回 404 Not Found。
我有以下文件结构：
例如，我的其中一个 API 文件如下：
import { PrismaClient } from '@prisma/client';const prisma = new PrismaClient();export default async function all(req, res) {if (req.method !== 'GET') {return res.status(405).json({ error: '不允许的方法' });}try {// 使用 Prisma 获取所有管理员const admins = await prisma.admin.findMany();return res.status(200).json(admins);}catch (error) {return res.status(500).json({ error: '获取管理员失败' });}}
当我发送 GET localhost:3000/api/admin/all 时，它总是返回 404。我找不到错误在哪里。
我尝试了其他文件或文件夹命名方式。从我的应用程序中调用，使用 curl 命令，或者使用 Postman。我的其他 API 路由也返回相同的 404 错误。
英文:
I am struggling with Next.js 13's app routing. It always gives me a 404 Not Found when I try to access fromPostmann for example.
I have this file structure:
And for example, one of my API files is:
import { PrismaClient } from '@prisma/client';const prisma = new PrismaClient();export default async function all(req, res) {if (req.method !== 'GET') {return res.status(405).json({ error: 'Method not allowed' });}try {// Get all admins using Prismaconst admins = await prisma.admin.findMany();return res.status(200).json(admins);}catch (error) {return res.status(500).json({ error: 'Failed to get admins' });}}
When I send a GET localhost:3000/api/admin/all it always responds with a 404. Couldn't find where is the error.
I tried other file or folder namings. Calling from my own app, using the curl command, or using Postman. My other API routes give the same 404.

API路由应该存储在名为route.js的文件中。意味着app/api/admin/all.js应该改为app/api/admin/route.js，对应的URL应为/api/admin。此外，函数内部应该使用特定的定义：
export async function GET(request) {}
GET可以替换为POST、PUT、PATCH等。在你的情况下，它应该是：
// 请注意NextResponse的导入位置：import { NextResponse } from "next/server";import { PrismaClient } from "@prisma/client";const prisma = new PrismaClient();// 请注意函数定义：export async function GET(req) {return NextResponse.json({ error: "Method not allowed" },{status: 405});}// 请注意函数定义：export async function POST(req) {try {// 使用Prisma获取所有管理员const admins = await prisma.admin.findMany();return NextResponse.json(admins, {status: 200,});} catch (error) {return NextResponse.json({ error: "Failed to get admins" },{status: 500,});}}
英文:
An API Route should be in a file called route.js. Meaning app/api/admin/all.js should be app/api/admin/route.js, with the corresponding URL being /api/admin. Also, the functions inside should use a specific definition:
export async function GET(request) {}
GET, can be replaced with POST, PUT, PATCH, etc. In your case, it would be:
// Notice from where NextResponse is imported:import { NextResponse } from "next/server";import { PrismaClient } from "@prisma/client";const prisma = new PrismaClient();// Notice the funciton definiton:export async function GET(req) {return NextResponse.json({ error: "Method not allowed" },{status: 405});}// Notice the funciton definiton:export async function POST(req) {try {// Get all admins using Prismaconst admins = await prisma.admin.findMany();return NextResponse.json(admins, {status: 200,});} catch (error) {return NextResponse.json({ error: "Failed to get admins" },{status: 500,});}}

除了Youssouf的回答（我觉得非常有帮助），如果你在获取request.body的内容时遇到问题，可以使用const body = await request.json()来获取请求体。

In addition to Youssouf's answer (which I found very helpful), if you have problems getting the content of request.body, use const body = await request.json() to get the body.
