查看有关 URL 参数的注释:
@param string $url 要重定向到的 URL。 注意,当 URL 不是
* 绝对(不以“/”开头)它将相对于当前请求 URL。
但是,在您的代码中,URL 以“/”开头,因此根据源代码,接下来会发生的事情是:$url = $this->getHostInfo().$url;
那么我们来看看getHostInfo函数的来源:
public function getHostInfo($schema='')
{
if($this->_hostInfo===null)
{
if($secure=$this->getIsSecureConnection())
$http='https';
else
$http='http';
if(isset($_SERVER['HTTP_HOST']))
$this->_hostInfo=$http.'://'.$_SERVER['HTTP_HOST'];
else
{
$this->_hostInfo=$http.'://'.$_SERVER['SERVER_NAME'];
$port=$secure ? $this->getSecurePort() : $this->getPort();
if(($port!==80 && !$secure) || ($port!==443 && $secure))
$this->_hostInfo.=':'.$port;
}
}
if($schema!=='')
{
$secure=$this->getIsSecureConnection();
if($secure && $schema==='https' || !$secure && $schema==='http')
return $this->_hostInfo;
$port=$schema==='https' ? $this->getSecurePort() : $this->getPort();
if($port!==80 && $schema==='http' || $port!==443 && $schema==='https')
$port=':'.$port;
else
$port='';
$pos=strpos($this->_hostInfo,':');
return $schema.substr($this->_hostInfo,$pos,strcspn($this->_hostInfo,':',$pos+1)+1).$port;
}
else
return $this->_hostInfo;
}
我建议您检查第一个条件是否返回 true(虽然我认为 _hostInfo 不太可能已定义)并检查 $this->getIsSecureConnection() 函数的结果。
