我正在使用Next.js版本13.4.1，并尝试使用multipart/form-data将文件发布到服务器。但是，当尝试这样做时，我收到一条错误消息，指出不支持该格式。我看到一些博客和其他开发人员成功地使用了这种方法，所以我相信这可能是我的代码或Next.js本身的一个bug。
我正在我的项目的app目录中工作，我试图将图像文件发布到服务器。在我的前端代码中，我已经实现了处理图像上传的必要函数。handleDragOver、handleDragLeave和handleDrop功能允许用户将图像拖放到指定区域。然后create函数处理表单提交，创建FormData的新示例并设置适当的值。
前端

const handleDragOver = (event: any) => {
    event.preventDefault();
    setDragOver(true);
};

const handleDragLeave = (event: any) => {
    event.preventDefault();
    setDragOver(false);
};

const handleDrop = (event: any) => {
    event.preventDefault();
    setDragOver(false);
    const file = event.dataTransfer.files[0];
    setImage(file);
};

const create = async (event: React.FormEvent<HTMLFormElement>) => {
    event.preventDefault();

    if (!image) {
        return;
    }

    const formData = new FormData();

    formData.set("name", name);
    formData.set("url", url);
    formData.set("image", image, image.name);

    const response = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/category`, {
        method: "POST",
        body: formData,
    });
    const data = await response;
    console.log(data);
};

后端
在后端，我实现了一个POST函数来处理请求。在这个函数中，我尝试使用request.formData()方法检索表单数据。

import prisma from "@/libs/prisma";
import { NextRequest, NextResponse } from "next/server";

export async function POST(request: NextRequest) {
  const formData = await request.formData();
  console.log(formData);
}

但是，当我提交表单时，我收到一条错误消息，指出不支持multipart/form-data格式。我已经检查了我的代码对其他例子在线，并没有看到任何明显的问题。我怀疑这可能是Next.js中的一个bug，或者是我的特定设置的兼容性问题。
我已经尝试了几种解决方案来解决我所面临的使用multipart/form-data将文件发布到服务器的问题。首先，我尝试使用一些博客文章中建议的库，但它不起作用。然后，我尝试更新所有依赖项，包括Next.js版本，但问题仍然存在。我甚至试图在Next.js的官方Discord服务器和互联网上找到解决方案，但我无法找到任何满意的答案。
我希望找到一个解决方案，允许我使用multipart/form-data成功地将文件发布到服务器。然而，尽管尝试了几种解决方案，我还没有能够解决这个问题。我仍在积极寻找解决方案，并将继续探索不同的选项，直到我能够成功地将文件发布到服务器。
