Hola, estoy tratando de obtener datos de una API "restCountries" y está bloqueado por la política CORS. No entiendo por qué, he intentado establecer encabezados en el archivo index.php con la función header(), pero ha fallado.

Estoy trabajando con un archivo docker-compose "php, php-fpm, mysql, nginx"

Mi petición :

 const getlistOfAllCountries = async () => { // const myHeaders = new Headers() const responseFromWorldApi = await fetch("https://restcountries.com/v3.1/all", { method: 'POST', headers : { 'Access-Control-Allow-Origin' : '*', "Content-Type": "application/json" } }); const listOfAllCountries = await responseFromWorldApi.json(); }

mi archivo default.conf
