Hi!

I have following situation:

I call a servlet in javascript. The servlet returns a byte stream of a PDF file.

The file is downloaded but badly in a wrong encoding!
When i dowload the data in the servlet to a file its different to the file saved via your script. See attachments. How can this be done correctly?

viaFileSaverScript.pdf
fromServlet.pdf

Thanks!

I have forgotten mostly all about jQuery. But you should fetch the data as a blob directly using xhrFields..

jquery is trying to download the data as plain text and encode it, you don't want that

Thanks for the fast reply!

Now i get

jquery-2.1.3.min.js?v=5.0.2.00.07:4 Uncaught InvalidStateError: Failed to read the 'responseText' property from 'XMLHttpRequest': The value is only accessible if the object's 'responseType' is ' or 'text' (was 'blob').

Made it now with help of

Good, i was going to say that most stackoverflow answer and articles refer to using plain xhr, as jquery don't have support for responseType yet Best apk downloader windows 10 1.

However, I found this transport that adds responseType support to jquery's ajax

Another solution is to use the new ajax api: fetch

consider the following code:

I thought shelf would return a response with content-type: application/atom+xml; charset=utf-8

but I get this:

content-type: application/octet-stream; charset=utf-8

After digging down in shelf code, it seems that the _adjustHeaders function doesn't compare headers names case insensitively.

Is that an intended behavior? If not, would you accept a PR fixing this?

I opened a PR with a possible fix #53
