Bug 171489 – Response.blob() has empty type when created with a ReadableStream and content-type header

• Status: RESOLVED
• Resolution: FIXED
• Component: Platform

[Ben Kelly]

WebKit is currently failing this WPT test:

fetch/api/response/response-consume.html

On the "from stream to blob" case.

This test is basically:


  var data = 'hello world';

  var stream = new ReadableStream({
    start: function(controller) {
      controller.enqueue(stringToArray(data));
      controller.close();
    }
  });

  var r = new Response(stream, { headers: [['content-type', 'text/plain']] });

  r.blob().then(b => assert_equals(b.type, 'text/plain'));

WebKit is failing because whenever a ReadableStream is passed as the body of the Response the blob() output will have an empty string Blob.type.
