failed to load headsq.vti and its .gz data file into browser #134

Open gzt036 opened 3 years ago

gzt036 commented 3 years ago

the http request to load headsq.vti always results in a 'download completed' dialog box, i tried with IE, chrome and firefox and the behaviour is the same. does this happen to you as well? just run the example in the development mode.

the problem is with vtk.js\Sources\IO\Core\DataAccessHelper\HttpDataAccessHelper.js Line 122

  // Make request
  xhr.open('GET', url, true);
  xhr.responseType =
    options.compression || array.dataType !== 'string'
      ? 'arraybuffer'
      : 'text';
  xhr.send();

xhr.responseType is set to 'arraybuffer', which is correct, the url to load is 1839938295fe4f0839c9df8d9fa67137.gz in public/headsq/data directory , after xhr.send(), instead of returning a 200 response, it opens a diaglog and returns a 204 response.
