Code:

var multer  = require('multer');

var storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, './photos')
    },
    filename: function (req, file, cb) {
        cb(null, file.fieldname + '-' + Date.now())
    }
})

var upload = multer({ storage: storage }).any()

app.post('/admin/uploadpicture', upload, function(req, res) {
    res.send('Test');
});

Not able to understand where i am missing, kindly suggest anything. Thank you in advance.

Answer 1

您可以使用upload.array（'field'）上传所需数量的文件。

Answer 2

Increase the field data limit using the limits option:

multer({
  limits: { fieldSize: 2 * 1024 * 1024 }
})

refer link

Answer 3

if after adding the limits to multer you are still seeing this issue, it is likely because you are attempting to upload the same image multiple times and it is having trouble over riding the previous image. i've uploaded a new pic
