laravel5.2版本，在iframe调用下，返回错误的跳转链接无法获取

我打印Request $request;
在iframe下，不是新建打开
+headers: HeaderBag {#47 ▼
#headers: array:13 [▼
"host" => array:1 [▶]
"connection" => array:1 [▶]
"content-length" => array:1 [▶]
"cache-control" => array:1 [▶]
"origin" => array:1 [▶]
"upgrade-insecure-requests" => array:1 [▶]
"user-agent" => array:1 [▶]
"content-type" => array:1 [▶]
"accept" => array:1 [▶]
"referer" => array:1 [▼
0 => "http://www.blog.com/admin",就是这里，只能获取到我顶端的URl,这就导致了跳转不成功，
]
"accept-encoding" => array:1 [▶]
"accept-language" => array:1 [▶]
"cookie" => array:1 [▶]
]
#cacheControl: array:1 [▶]
}

我在新建的时候，是正常的，获取到如下
Request {#41 ▼
#json: null
#convertedFiles: null
#userResolver: Closure {#344 ▶}
#routeResolver: Closure {#343 ▶}
+attributes: ParameterBag {#43 ▶}
