nextjs当后端使-读取excel文件

目前nextjs有种php的感觉，现在的需求是读取excel文件，入数据库，拆分出读取excel的代码如下：

import { NextRequest } from "next/server";
import { join } from "path";
import { readFile } from "fs/promises";
import * as XLSX from "xlsx";export async function POST(req: NextRequest) {const uploadDir = join(process.cwd(), "public", "/assets");const filepath = `${uploadDir}/wp_postmeta.xlsx`;try {const fileContent = await readFile(filepath);const workbook = XLSX.read(fileContent, { type: "buffer" });const sheetName = workbook.SheetNames[0]; // Assuming there's only one sheetconst sheetData = XLSX.utils.sheet_to_json(workbook.Sheets[sheetName]);console.log(sheetData);return new Response(JSON.stringify({ message: "文件处理成功" }), {status: 200,});} catch (error) {console.error("Error reading or processing XLSX file:", error);return new Response(JSON.stringify({ error: "文件处理错误" }), {status: 500,});}
}
