ZS2中CORS POST请求变成OPTIONS请求代替

Question

Zend Framework 2中是否有允许在我的API上使用CORS？

我已经让所有的起源header("Access-Control-Allow-Origin: *");

我每次发送POST请求页眉服务器以405

回应在我的访问日志，我看到的要求实际上是OPTIONS

Answer 1

所以开始你的PHP脚本应该做这些检查：

// Allow from any origin 
if (isset($_SERVER['HTTP_ORIGIN'])) { 
    header("Access-Control-Allow-Origin: {$_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, OPTIONS");   

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

    exit(0); 
} 

一旦你这样做，CORS将被启用。
