I have a fileupload and a spring controller to receive the images from the form submit. My spring controller is working, i see the request and the success response but my form callback give me this error.

responseText:"{success:false,message:"Blocked a frame with origin "http://localhost"from accessing a cross-origin frame."}"In the browser request, i see the correct response but i dont see this response. What is can do to solve my problem?

Thanks for the report. I couldn't find any existing reports of this. Can you please post a test case which reproduces this issue?

When i use a filefield, an hidden iframe is generated to receive the server response? Maybe this is my problem

Could be. This behavior is described in the docs:

I'm facing the problem even the server returning a Content-Type header with "text/html" value.

What about if you try a Content-Type of 'text-plain'?

Same problem with Conten-Type set to text/plain.

Are you trying to submit the form to a different domain or IP than the one hosting it?

Yes it is from another domain.It seems to be a CORS issue.

Yes. Here's a link that might help with that:

I have this same problem with Ext JS 6. I need to upload file to a Restful API. How to fix this? Thanks

Are you submitting the file to a different domain than the one on which the form is hosted?

Yes, I am! I have an Ext JS front app, and an external restful api in other domain

Are you submitting the file to a different domain than the one on which the form is hosted?

What is the solution/best practice to upload files using a RESTful API to a different domain?

Any solution for this? I need to call a REST-API on another domain for file uploading. After days of search I still don't have a solution.

If it does matter: i use ExtJS6

I'm afraid for now the solution here is to use the same domain for file uploads.

22 Dec 2016, 1:56 AM
Okay. What I need:
- upload file (prefer cross domain)
- custom headers

2 Possible solutions:

1) submit():
- no cross domain (i can live with that)
- no custom headers

2) Ajax.request():
- cross domain possible
- custom header
- no file upload

So both solutions are not perfect. Regarding to the Ajax file upload I saw that it should be possible with XHR2.

So it is just a limitation of ExtJS? It is really confusing.

There is a feature request (EXTJS-12483) to add XHR2 to the framework, but it has yet to be implemented.
