Video successfully uploaded when use ajax post method but CORS policy error show!

[hunglas]

I am using "form-based approach" follow steps:

1. I created a video via POST method from server (success)
2. Get upload_link from step 1 and use it for ajax post method but I got error even video had successfully uploaded to Vimeo:
   

Can some body help me to understand how can successfully uploaded video like this way without error like this? Thanks so much!

Ajax Post code:

var formData = new FormData(form);
formData.append("file_data", file);
$.ajax({
'url': uploadLink,
'type': 'POST',
'method': 'POST',
'dataType': 'multipart/form-data',
'data': formData,
'contentType': false,
'processData': false,
'cache': false,
}).done(function(data) {
console.log('final', data);
}).fail(function(err){
console.log('error', err);
});
