如何修复Node.js中的'TypeError:无法读取未定义的属性'path''(Multer) [英] How to fix 'TypeError: Cannot read property 'path' of undefined' in Nodejs(Multer)

问题描述

我正在尝试上传文件，但存在'TypeError:无法读取未定义的属性'path'.有什么办法解决这个问题?

I am trying to upload the file but there is 'TypeError: Cannot read property 'path' of undefined'. Is there any way to solve this?

exports.postimport = function (req,res) {

var storage = multer.diskStorage({
destination: function(req, file, cb) {
    cb(null, 'uploads');
},
filename: function(req, file, cb) {
    cb(null, file.originalname);
}
});

 var upload = multer({
 storage: storage,
}).single('sheet');
 upload(req, res, function(err) {
    if (err) {
        res.send(err)
       } else {
        console.log(req.file.path);
       }
});
}

推荐答案

获取未定义路径的原因可能是目标目录(即上载文件夹的路径)不正确.

The reason you might be getting path of undefined may be that your destination directory (i.e path to your uploads folder) is not correct.
