我正在尝试使用Slim Framework编写的REST API。
GET和POST方法可以正常工作,但DELETE请求无法正常工作。 我收到“Method DELETE is not allowed by Access-Control-Allow-Methods”的错误提示。
我已经在标头中允许了OPTIONS和DELETE。请参见下面的代码。
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?
