I am posting a file to a node server, it gives me a 404 status error
My HTML file is like the following,
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>file</title>
</head>
<body>
<form method="post" action="/getusrfile" enctype='multipart/form-data'>
<input type="file" name="fil" >
<button type="submit">
sub
</button>
</form>
</body>
</html>
I am using node, express this:
app.post("/getusrfile",function(req,res){
console.log("came to server");// prints this
console.log(req.files);//prints undefined
//console.log(JSON.stringify(req.files.fil));
fs.readFile(req.files.fil, function (err, data) {
// ...
var newPath = __dirname + "/../public/uploadedFileName";
fs.writeFile(newPath, data, function (err) {
console.log(err);
res.send(err);
});
});
});
It is outputted to the server, but no file / directory is created on the server. And the response is "Can not POST / getusrfile" with a 404 status.
and req.files prints undefined
How do I make it work?

The first
$ npm install --save multer
Then add the multer middleware before the app.post function:
app.use(require('multer')({dest : __dirname }));
app.post("/getusrfile",function(req,res){
var filePath = req.files.fil.path;
fs.readFile(filePath, function (err, data) {
// ...
});
});
Test:
it('should respond "OK 200" to POST request with file payload',function(done){
var filePath = path.join(__dirname,'test.txt');
request(app)
.post('/getusrfile')
.attach('fil',filePath)
.expect(200)
.end(function(err,res){
expect(err).to.not.exist;
done();
});
});
