我在我的PHP脚本中使用cURL来测试我的API。当我尝试使用我的函数来获取数据时，它抛出了一个错误
错误：无法连接到alenke。测试端口80：连接被拒绝
但当我在终端执行时

curl --ipv4 -v "http://alenke.test/wp-json/chatbot/v1/brand";

它给予了我

`Trying 127.0.0.1...

并给予我所有的数据，我需要，但何时执行这个php脚本

function callAPI($method, $url, $data){
        $curl = curl_init();
        switch ($method){
            case "POST":
                curl_setopt($curl, CURLOPT_POST, 1);
                if ($data)
                    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
                break;
            case "PUT":
                curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
                if ($data)
                    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
                break;
            default:
                if ($data)
                    $url = sprintf("%s?%s", $url, http_build_query($data));
        }
        // OPTIONS:
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_HTTPHEADER, array(
            'Content-Type: application/json',
        ));
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt($curl, CURLOPT_USERPWD, "admin:admin");
        // EXECUTE:
        $result = curl_exec($curl);
        if(!$result){
            if (curl_errno($curl)) {
                echo 'Error: ' . curl_error($curl);      
                echo'//;
                echo print_r(curl_getinfo($curl));   
                echo'//;
                die("Connection Failure..?");
            }
        }
        curl_close($curl);
        return $result;
    }

它会显示此错误
