响应状态200但没有JSON

Question

I am using PHPMailer to send mails but its from my localhost in xampp. When I test my API in Postman, it takes too long to process the request but renders response status 200 but no JSON response returned. Below are my codes.

    public function actionSendMail() {
    //Getting request from frontend
    $request = file_get_contents('php://input');

    //Decoding input into an array
    $input = json_decode($request, true);

    //Validating request
    if (is_null($input)) {
        $response = json_encode(['error' => 'Bad Input']);
        die($response);

    } else {
        //mail parameters
        $to      = $input['to'];
        $subject = $input['subject'];
        $body    = $input['body'];
        $headers = $input['headers'];

        //Sending mail 
        if($result = $this->sendMail($to, $subject, $body, $headers) === true) {
            $response = json_encode(['success' => true]);
            echo $response;
        } else {
            $response = json_encode(['error' => 'Mail Not Sent']);
            die($response);
        }
    }
}

private function sendMail ($to, $subject, $body, $headers) {
    //Configurating PHP Mailer
    $mail = new PHPMailer();

    $mail->IsSMTP();                                 
    $mail->Host = 'secure.emailsrvr.com';  
    $mail->Port = 995;
    $mail->SMTPAuth = true;                            
    $mail->Username = '[e-mail]';                           
    $mail->Password = '****';                          
    $mail->SMTPSecure = 'ssl';                   
    $mail->WordWrap = 50;      
    $mail->IsHTML(true); 

    $mail->SetFrom('[e-mail]');
    $mail->AddReplyTo($headers);
    $mail->Subject = $subject;
    $mail->MsgHTML($body);
    $mail->AddAddress($to, "");

    if(!$mail->Send())
        return $mail->ErrorInfo;

    return true;
}

Thanks for your time.

You need to test your mail sending code in isolation - errors are being hidden behind your other code. A long delay most likely means you're having a network timeout, either due to bad connectivity or DNS timeout. Try setting $mail->SMTPDebug = 3; so you can see connection errors. Check the PHPMailer troubleshooting guide.
