下载带有HTTP标头的文件

Question

I'm looking for dowloading PDF files with html links with HTTP authentication header.

It is not possible to fix them without javascript, so I tried this :

Html :

<a id="myLink" href="">fileName.pdf</a>

Javascript :

$("#myLink").on("click", function() {
        var xhr = new XMLHttpRequest();
        xhr.open("GET", myUrl, true);
        xhr.setRequestHeader("X-Token", authToken);
        xhr.send();
        return false;
});

File is downloaded (regards to network analysis) but I don't know how to open it in a new browser tab. I know we don't save files from javascript but I just want to display it. Do you have any idea ?

Thanks.

Answer 1

Solution was to store header value inside a cookie.

When using RestEasy, cookie can be read inside an http filter (preProcess function for RestEasy 2.3.7.Final) with :

request.getHttpHeaders().getCookies()

request is an HttpRequest object.

There's still one "problem", files are never opened inside browser. I don't know how to fix this yet.
