我正在尝试使用Slim Framework编写的REST API.

Get&Post方法没有任何问题.但是DELETE请求不起作用.我得到" Access-Control-Allow-Methods " 不允许 " 方法删除 "

我已经允许OPTIONS以及标题中的DELETE.见下面的代码.

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Content-Type');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');

$app->options('/(:name+)', function() use($app) {                  
    $response = $app->response();
    $app->response()->status(200);
    $response->header('Access-Control-Allow-Origin', '*'); 
    $response->header('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, X-authentication, X-client');
    $response->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
 });

这个请求失败的原因是什么？
