我正在为特殊类型的用户制作一个注册页面，表单有一个输入类型文件，即用户个人资料图片，但提交表单时该文件似乎没有发送到服务器端，并且它返回错误“TypeError：无法读取未定义的属性（读取'split'）”
由于某种原因，我无法检查服务器端的文件mimetype，这似乎是错误
我在编码这些类型的表单时从未遇到过任何问题，但现在我不知道为什么会发生此错误。
app.post('/cadastroFruteira', function (req, res) {
try {
var form = new formidable.IncomingForm();
form.parse(req, (err, fields, files) => {
if(files.logo.mimetype){
if (err) throw (err)
var oldpath = files.logo.filepath;
var hashImagem = crypto.createHash('md5').update(Date.now().toString()).digest('hex');
var nomeimg = hashImagem + '.' + files.logo.mimetype.split('/')[1];
var newpath = path.join(__dirname, 'public/imagens/', nomeimg);
mv(oldpath, newpath, function (err) {
if (err) throw err;
});
bcrypt.hash(fields['senha'], saltRounds, function (err, hash) {
var sql = "INSERT INTO fruteira (nome, email, CNPJ, senha, endereco, instagram, telefone, logo) VALUES ?";
var values = [
[fields['nome'], fields['email'], fields['CNPJ'], hash, fields['endereco'], fields['instagram'], fields['telefone'], nomeimg]
];
con.query(sql, [values], function (err, result) {
if (err) {
console.error(err);
throw err;
}
console.log(result.affectedRows);
});
});
}else{
throw new Error("Invalid file or mimetype");
}
});
}catch(error){
throw error;
}
res.redirect('/loginFruteira'); // Redirect after database operation
});
});
请求发送后，返回消息 Invalid file or mimetype

好吧，我不久前已经解决了这个问题，但我真的没有找出是什么导致了这个问题，所以我决定使用 Multer 而不是 Formidable，它工作得很好
