无法在 React 中从我的 API 服务器获取数据

Question

I try to fetch data (list of files in folder) from my server https://www.my-site.com/api where I've got index.php file which is

<?php
    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/json");

    $dir = "./photos"; //path

    $list = array(); //main array

    if(is_dir($dir)){
        if($dh = opendir($dir)){
            while(($file = readdir($dh)) != false){

                if($file == "." or $file == ".."){
                    //...
                } else {
                    $list3 = array(
                        'url' => $file);
                        array_push($list, $list3);
                }
            }
        }

        $return_array = array('photos'=> $list);

        echo json_encode($return_array);
    }
?>

and in my React app i try to use fetch

fetch('https://www.my-site.com/api', {
   method: 'GET',
   redirect: 'follow',
   headers: {
  }
})
  .then(response => response.json())
  .then(res => console.log(res))
  .catch(error => console.log('error', error));

but the result is CORS request did not succeed and CORS header 'Access-Control-Allow-Origin' missing . When im using Postman, everything it's ok, and I get json object with data I wanted.

Answer 1

Try to add :

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"

To .htaccess file
