Ajax request and CORS

I’m trying to get the RSS feeds from multiple websites. However, I ran into a problem which I’m not sure how I can solve it.

First, for some RSS feeds, my code works, like this one:

function requeteRSS(){
    let url = "https://rss.nytimes.com/services/xml/rss/nyt/World.xml";
    $.ajax(url, {
        method: "GET",
        complete: function(element){
            let xmlContent = element.responseText;


However, for many RSS url, I get a CORS error and my function doesn’t work, like for this link : http://feeds.bbci.co.uk/news/rss.xml
And the CORS error for many links like the one above : No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
Why is that and how I can solve this problem? Thanks you!

According to the MDN,
If the server sends a response with an Access-Control-Allow-Origin value that is an explicit origin (rather than the " * " wildcard), then the response should also include a Vary response header with the value Origin — to indicate to browsers that server responses can differ based on the value of the Origin request header.

Access-Control-Allow-Origin: https://developer.mozilla.org
Vary: Origin

How can I do to not have this type of errors, because I do not obtain the .xml when this type of errors happens.

the server block the access to this resources and it demand to subscribe.

question markHelp, I don't know what a news reader is and still don't know what this is about.

Hi, thanks for your response,
I’m not sure the issue is with subscribing, since that I get the same issues for many websites who provides rss feed like this one: dailytelegraph.com.au/news/breaking-news/rss

You can try with others, like I said some works some doesn’t and I want them all to work, without any Cors errors.
This one doesn’t give me a cors error: https://rss.nytimes.com/services/xml/rss/nyt/World.xml

You need to use a proxy (either your own) or one like cors-anywhere.herokuapp.com
