我试图上传PDF文件（简历）在未来的js，一切都很好，根据我的期望，但在后端时，我
console.log（req.data）
它告诉我
[object：object]

注意当我console.log数据在前端它的工作正常，我看到所有的数据，包括文件的形式，但在后端我无法获得该数据

1.我尝试在下一个API中将bodyparser配置为false，如果我这样做，我将不会在后端接收任何数据
如何解决此问题

发布请求

export const apply_job = async (formData) => {
    console.log(formData)
    try {
        const res = await fetch(`${process.env.NEXT_PUBLIC_API_BASE_URL}/api/job/applyJob`, {
            method: 'POST',
            headers : {
              'Content-Type': 'multipart/form-data',
            },
            body: formData,
          });
        const data = await res.json();
        return data;
    } catch (error) {
        console.log('error in apply job (service) => ', error);
    }
}
