cors

Hi,

Thanks a LOT for you simple and useful tool.

I generates html pages in yacron tasks, in that html file I setup a call to the REST api to regenerate the report using XMLHttpRequest

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
                    if (this.readyState == 4) {
                        if (this.status == 200) {
                                location.reload();
                        } else {
                            window.alert("error: " + this.status + " " + this.statusText);
                        }
                    }
                };
xhttp.open("POST", "http://localhost:8181/jobs/<jobname>/start", true);

The browser isn't happy and raise a CORS error.
If I understand correctly, this cors error is due to a missing header rendered by the yacron rest api server which should add the header Access-Control-Allow-Origin in the response.

Is there a way to add this header in the embedded rest server that is aiohttp ?

I saw the module https://github.com/aio-libs/aiohttp-cors, but my usage is very simple

You could add headers if you had e.g. an nginx in front proxying the requests.

Nevertheless, perhaps it's not a bad idea to add support for custom headers in the web server via config:

web:
  listen:
     - http://127.0.0.1:8080
     - unix:///tmp/yacron.sock
  headers:
    Access-Control-Allow-Origin: *

Could be cool.
When I'll have time, I'll try to add it, while this moment I'll do the ugly hack, just after installing yacron

RUN sed -i 's/return web.Response()/return web.Response(headers={"Access-Control-Allow-Origin":"*"})/g' /usr/local/lib/python3.10/site-packages/yacron/cron.py
