自定义标头在 PHP 中给出 CORS 错误

我正在尝试基于 REST 的跨域请求。 两个域将托管在同一台服务器上。

domain1：http://testdata.local - 用于将在域 2 上请求 REST API 的应用程序。

domain2：http://api.testdata.local - 用于处理来自域 1 的 REST API 调用

每个 REST API 调用都有一些域 2 所需的自定义标头。

现在，当我通过 ajax 向域 2 调用 REST API 请求时，我收到 CORS 阻止错误。

以下是我正在尝试的代码：

域 2 上示例 API 请求的 PHP 代码：

class mytest{
    public function setOriginPolicy() {
        if (isset($_SERVER['HTTP_ORIGIN']) && $_SERVER['HTTP_ORIGIN'] == 'http://testdata.local') {
            header("Access-Control-Allow-Origin: {$_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']}");
            }
            exit(0);
        }
    }
    public function testrequest(){
            $this->setOriginPolicy
            $result['config_status'] = 1;
            $result['config_msg'] = "request ok";
            echo json_encode($result);
    }
}

来自域 1 的 AJAX 调用：

var url = "http://api.testdata.local/mytest/testrequest";
$.ajax({
    type: 'GET',
    url: url,
    async: true,
    crossDomain:true,
    //jsonpCallback: 'jsonCallback',
    contentType: "application/x-www-form-urlencoded",
    headers:{"API_KEY":"andapikey","APP_VERSION":"1.0","CONFIG_VERSION":"1.0","AUTH_TOKEN": "4a6b1e610e81fa19c76a557049e9fa19"
    },
    /*beforeSend: function( xhr ) {
        xhr.setRequestHeader("API_KEY", "andapikey"); 
        xhr.setRequestHeader("APP_VERSION", "1.0");
        xhr.setRequestHeader("CONFIG_VERSION", "1.0");
        xhr.setRequestHeader("AUTH_TOKEN", "4a6b1e610e81fa19c76a557049e9fa19");
    },*/
    success: function(json) {
        console.log(json);
    },
    error: function(e) {
        console.log(e.message);
    }
});

如果我禁用标头，我会得到响应。

请建议

Header always set Access-Control-Allow-Origin "http://testdata.local"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
Header always set Access-Control-Max-Age "1000"
