PHP无法获取Referer问题排查,referer排查

测试结果:

'测试来源:直接载入页面
'; echo '进入页面
'
; echo '测试来源:新窗口打开
'
; echo '进入页面
'
;

test_cookie.php的代码为:

<?php

date_default_timezone_set(<span class="str">'Asia/Shanghai'</span>);<span class="rem">//设置默认时区</span>
header(<span class="str">'content-type:text/html; charset=utf8'</span>);<span class="rem">//设置返回头信息</span>

echo date(<span class="str">'Y-m-d H:i:s'</span>);
echo <span class="str">"<br/>\r\n"</span>;

echo <span class="str">'PHP获取Refer是:'</span>;
$refer=isset($_SERVER[<span class="str">'HTTP_REFERER'</span>])?$_SERVER[<span class="str">'HTTP_REFERER'</span>]:<span class="str">'No refer found'</span>;
echo $refer;
echo <span class="str">"<br/>\r\n"</span>;

echo <span class="str">'JS获取Refer是:'</span>;
    echo <span class="str">"<script>document.writeln(document.referrer);</script>"</span>;
echo <span class="str">"<br/>\r\n"</span>;

  
Copy after login

极度好奇是什么原因造成的第一次能获取,第二次不能获取。

 

环境是LNMPA,官方是http://lnmp.org/lnmpa.html

 

Mac下用charles抓包

2次请求test1.php的header是一致的。

2次请求test_cookie.php的header是一致的。

 

那么问题来了,什么原因造成的2次完全一模一样的请求,PHP取不到refer。跪求解。
