此代码无效！我需要在页面中使用axios，但CORS策略已阻止从原点“ https://google.com/”访问“ http://easysaham.ir”处的XMLHttpRequest：在“”中没有“ Access-Control-Allow-Origin”标头请求的资源。
<?php header('Access-Control-Allow-Origin: *'); ?>
<!DOCTYPE html>
<html>
<head><meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
<title>Title</title>
</head>
<body>
<script src='https://unpkg.com/axios/dist/axios.min.js'></script>
<script>
axios.get('https://google.com/').then(response => {
console.log(response.data);
});
</script>
</body>
