Php 在 .htaccess 中启用 cors

因为我把所有的东西都转发到了索引.无论如何，我想我应该try 用php来设置标题，而不是.htaccess文件成功了！耶！以下是我添加到索引中的内容.php为其他任何有此问题的人提供.

// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
    // should do a check here to match $_SERVER['HTTP_ORIGIN'] to a
    // whitelist of safe domains
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");         

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

}

他的答案是this question分，功劳归功于他的杀手锏

因为我使用的是Slim，所以我添加了此路由，以便OPTIONS请求获得HTTP 200响应

// return HTTP 200 for HTTP OPTIONS requests
$app->map('/:x+', function($x) {
    http_response_code(200);
})->via('OPTIONS');
