ErrorException: 警告: 标题不能包含多个标题,检测到新行 [英] ErrorException: Warning: Header may not contain more than a single header, new line detected
问题描述
我在发送电子邮件的某个功能后无法重定向!我的功能是:
I am having trouble redirecting after a certain function that sends emails! My function is:
public function emailAction($emails, $url)
{
foreach($emails as $email)
{
$message = \Swift_Message::newInstance()
->setSubject('Updates in Symfony Blog')
->setFrom(array('blog@symfonyblog.com' => 'Symfony Blog'))
->setTo($email["email"])
->setBody(
$this->renderView(
'NEWSBlogBundle:Default:email.txt.twig',
array('url' => $url)
)
)
;
$this->get('mailer')->send($message);
}
return $this->redirect($this->newpostAction());
//return $this->redirect($this->generateUrl('NEWSBlogBundle_homepage'));
}
它发送电子邮件正常,但是在重定向时出现错误:
It sends the emails OK, but then when redirecting, gives the error:

虽然我没有改变任何关于标题"的东西(我真的不知道它是关于什么的!).我的 app_dev.php 是:
while I haven't changed anything about any "headers" (and don't really know what it is about!). My app_dev.php is:
<?php
use Symfony\Component\HttpFoundation\Request;
if (isset($_SERVER['HTTP_CLIENT_IP'])
|| isset($_SERVER['HTTP_X_FORWARDED_FOR'])
|| !in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'fe80::1', '::1'))
) {
header('HTTP/1.0 403 Forbidden');
exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
我尝试了两种不同的重定向方式(通过路由和直接调用控制器),它们给出了相同的错误,而如果我输入他们的 url,页面就会加载!
I tried two different ways of redirecting both (through routing and directly calling the controller) of which give the same error, whilst the pages load if I jusr type in their url!
我不知道这个错误是什么以及我应该如何修复它!
I have NO idea what this error is and how I should fix it!
推荐答案
详细来说,你的问题是 $this->newpostAction()
的返回值.通常它是一个 Response
对象.但是重定向需要一个 uri/route,它可以通过 Location
标头发送到客户端.重定向始终是客户端转向.但是您可以使用 ->forward('AcmeBundle:Demo:index')
在内部转发到另一个控制器操作.在这种情况下,客户端上的 URL 不会更改.
To be detail, your problem was the return value of $this->newpostAction()
. Usally it's a Response
object. But a redirect expects an uri/route, which can be sent to the client via the Location
header. A redirect is always a client side turn around. But you can use ->forward('AcmeBundle:Demo:index')
to forward internally to another controller action. In this case the URL on the client is not changed.
