header 跳转时报错误。Header may not contain more than a single header, new line detected
我在用php的header做跳转时,报错误。
Header may not contain more than a single header, new line detected
先贴一下代码:
class advertJumpUrl { /** * 广告唯一的key * @return array */ private static function aGetKey() { $sKey = Ko_Tool_Input::VClean("r","k",Ko_Tool_Input::T_STR); $sKey = \apps\brand\cpm\MFacade_LogApi::sDecrypt($sKey); $aPara = explode('_', $sKey); return $aPara; } /** * 广告跳转的url * @return url */ private static function sGetUrl() { $sUrl = Ko_Tool_Input::VClean("r","t",Ko_Tool_Input::T_STR); return \apps\brand\cpm\MFacade_LogApi::sDecrypt($sUrl); } /** * 程序执行 */ public static function vRun() { $aPara = self::aGetKey(); $sUrl = self::sGetUrl(); // $sUrl = rawurldecode($sUrl); if($aPara && $sUrl) { // 记录点击事件 \apps\brand\cpm\MFacade_LogApi::vClick($aPara[1], $aPara[0]); header('HTTP/1.1 301 Moved Permanently'); header('location:'.$sUrl); exit; } header('HTTP/1.1 301 Moved Permanently'); header('location:/'); exit; } } advertJumpUrl::vRun();
在网上搜索一下,是因为URL编码有问题。我尝试用urlencode 然后再urldecode。发现不行。
有人建议用rawurlencode。我试了试,成功了。
urlencode 和rawurlencode 的区别:
urlencode 将空格则编码为加号(+)
rawurlencode 将空格则编码为加号(%20)
