【问题描述】：

我正在使用express-fileupload 在我的服务器中上传文件。它可以工作，但是当我尝试上传 DOCX 文件时，req.files 显示它为空我的测试代码

exports.uploadFile = async (req,res) => {
   console.log(req.files);
   await res.json({
    success: true,
    message: "File uploaded!"
   })
}

【解决方案1】：

没有足够的数据。

尝试：

检查您使用的是 express-fileupload 1.1.6 或更高版本。
将 express-fileupload 选项调试设置为 true。
共享调试输出。

您应该会看到如下内容：

}

我已尝试上传 docx，但没有遇到任何问题。
