我无法从JavaScript对象中检索值。
我已经尝试了几种方法，但我不能让它工作的通常方式，我现在，但我是相当新的javaScript。
感谢您的时间和关注，如果有任何遗漏或您需要一些更多的信息，请与我联系。

{
 'mFile ': {
    name: 'test',
    data: { type: 'Buffer', data: [Array] },
    size: 4,
    encoding: '7bit',
    tempFilePath: '',
    truncated: false,
    mimetype: 'application/octet-stream',
    md5: '098f6bcd4621d373cade4e832627b4f6'
  }
}

我的代码：

app.post('/single', async(req, res, next) => {
try {
    
    const unpackedReq = JSON.parse(JSON.stringify(req.files));
    const file = unpackedReq.mFile

    console.log(unpackedReq)
    console.log(typeof(unpackedReq)) //object
    console.log(unpackedReq["mFile"].name) // TypeError: Cannot read properties of undefined (reading 'name')

} catch (error) {
    console.log(error)
    res.send('Error uploading file')
}
