发现baidu spider 仍然抓取的url地址为 /19/wdy999/ 而我们使用php header函数转到了 /wdy999/这样的地址上
所以猜测：对于百度搜索引擎蜘蛛baidu spider 对302 仍然可以抓取到文章，但是对于url的收录仍然收录的是旧URL地址 /19/wdy999/
优化方法： 使用header("Location: /foo.php",TRUE,301);
header("Location: /foo.php",TRUE,301);
header("Location: /foo.php",TRUE,302);
header("Location: /foo.php");
header("Location: /foo.php",TRUE,303);
header("Location: /foo.php",TRUE,307);
?>
