lumen设置cookie出错

Type error: Argument 1 passed to SymfonyComponentHttpFoundationResponseHeaderBag::setCookie() must be an instance of SymfonyComponentHttpFoundationCookie, string given, called in /data/www/www.test.com/vendor/illuminate/http/ResponseTrait.php on line 83

这个错误，怎么导致的啊

回复内容：

Type error: Argument 1 passed to SymfonyComponentHttpFoundationResponseHeaderBag::setCookie() must be an instance of SymfonyComponentHttpFoundationCookie, string given, called in /data/www/www.test.com/vendor/illuminate/http/ResponseTrait.php on line 83

这个错误，怎么导致的啊

錯誤就講明了：參數是需要 Symfony\Component\HttpFoundation\Cookie 你卻丟 string

正確用法應該是：

use Symfony\Component\HttpFoundation\Cookie;

$response->headers->setCookie(new Cookie('foo', 'bar'));
