穆特: fileFilter不工作
穆特: fileFilter不工作
提问于 2018-02-12 10:37:37
我在用穆特上传文件。一切都很好，但fileFilter不起作用。我不知道我哪里出了问题。
routes.js
var multer = require('multer');
// Multer diskStorage setting
var storage = multer.diskStorage({
destination: function (req, file, callback) {
callback(null, './uploads/');
},
filFilter: function (req, file, cb) {
var typeArray = file.mimetype.split('/');
var fileType = typeArray[1];
if (fileType == 'jpg' || fileType == 'png') {
cb(null, true);
} else {
cb(null, false)
}
},
filename: function (req, file, callback) {
callback(null, file.fieldname + '_' + Date.now() + '.jpg');
}
});
var upload = multer({ storage: storage });
router.post('/add', upload.single('photo'), function(req, res){
console.log('uploaded');
}穆特还上传了不允许的文件。有什么想法吗？

fileFilter必须用穆特的options对象而不是diskStorage来定义
const uploadFilter = function(req, file, cb) {
// filter rules here
}
const upload = multer({
storage: storage,
fileFilter: uploadFilter,

const storage = multer.diskStorage({
destination: function (req, file, callback) {
callback(null, './uploads/');
},
fileFilter: function (req, file, cb) {
const extension = path.extname(file.originalname).toLowerCase();
const mimetyp = file.mimetype;
if (
extension !== '.jpg' ||
extension !== '.jpeg' ||
extension !== '.png' ||
mimetyp !== 'image/png' ||
mimetyp !== 'image/jpg' ||
mimetyp !== 'image/jpeg'
) {
cb('error message', true);
}
},
filename: function (req, file, callback) {
callback(null, file.fieldname + '_' + Date.now() + '.jpg');
},
});
const upload = multer({ storage: storage });
router.post('/add', upload.single('photo'), function (req, res) {
console.log('uploaded');
});我想这会有帮助的

在您的fileFilter上有一个错误；您已经将它命名为filFilter。你能把你的代码改为下面的代码并告诉我们它是否成功了吗？
var multer = require('multer');
// Multer diskStorage setting
var storage = multer.diskStorage({
destination: function (req, file, callback) {
callback(null, './uploads/');
},
fileFilter: function (req, file, cb) {
var typeArray = file.mimetype.split('/');
var fileType = typeArray[1];
if (fileType == 'jpg' || fileType == 'png') {
cb(null, true);
} else {
cb(null, false)
}
},
filename: function (req, file, callback) {
callback(null, file.fieldname + '_' + Date.now() + '.jpg');
}
});
var upload = multer({ storage: storage });
router.post('/add', upload.single('photo'), function(req, res){
console.log('uploaded');
