CKEditor 4.5 filetools, how to set XHR.withCredentials = true,

Question

In CKEditor 4.5 beta, filetools plugin fails to set cookies while using cross domain upload url, for CORS to enable cookies we require to set XHR.withCredentials = true while upload XHR getting initiated.

How can i set XHR properties in filetools plugin in CKEditor 4.5.

Answer 1

You can get access to XHR object by listening to fileUploadRequest event and then you can set withCredentials flag to true.

editor.on( 'fileUploadRequest', function( evt ) {
    var xhr = evt.data.fileLoader.xhr;

    xhr.withCredentials = true;
} );
