upload: function (req, res) {
console.log(req.headers);
console.log(req.body);
req.pipe(request.post('http://localhost:1337/file/upload')).pipe(res);
}
and here is code for server2:
upload: function (req, res) {
console.log(req.allParams());
console.log(req.file());
console.log(req.headers);
if (req.file("mot")) {
req.file('mot').upload({
dirname: require('path').resolve(sails.config.appPath, 'data')
}, function (err, data) {
if (err) {
console.log(err);
return res.json({
failed: true
});
} else {
console.log("file uploaded");
return res.ok();
}
}
)
}else{
}
}
