被 CORS 策略与 nginx docker 阻止

Question

您好，我正在尝试从 API "restNations" 获取数据，但它被 CORS 策略阻止了。我不明白为什么，我试图使用 header() 函数在 index.php 文件中设置标头，但

失败了。我正在使用docker-compose文件"php，php-fpm，mysql，nginx">

我的要求 ：

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(); 

}

我的 default.conf 文件

server {
server_name ~.*;


location / {
root /usr/src/app;
try_files $uri /index.php$is_args$args;

}

location ~ ^/.+.php(/|$) {

API https://restcountries.com/v3.1/all 不允许执行 POST 方法。 将方法从POST更新为GET
