Hello
I try to replace this service:
http://allorigins.win/
"Pull contents from any page via API (as JSON/P or raw) and avoid Same-origin
policy problems"
I use JAX-RS, I obtain an HTTP error 404 when trying to use my web service:
http://80.13.94.99/feed/webresources/corsproxy/raw?url=https%3A%2F%2Fwww.lemonde.fr
I use "feed" in the deployment descriptor for Jetty,
@ApplicationPath("webresources"), @Path("corsproxy") and
@Path("raw?url={url}"), that's why I expected the above path to work.
I have to parse XML (RSS, Atom, OPML) files on the client, in Javascript.
However, many CORS policies prevent me from doing that directly in the client.
I use http://allorigins.win but I don't want to rely on a third party CORS
proxy on the long term. Using a CORS proxy allows the client to bypass CORS
policies to be able to get the files and parse them.
I use Tor Browser and Mozilla Firefox 68 & 79. I don't use my broken CORS proxy
in Javascript yet, I wanted to make sure it works in my test in a web browser
by accessing the URL of the web service before using it in my source code. I
want to use it here:
https://sourceforge.net/p/red-feed-aggregator/code/ci/master/tree/src/main/webapp/feed.js#l272
Thank you for your help.
