在header送出之前不能有echo

escil · 发表于 2004-12-4 02:58:58

<?
if(!isset($PHP_AUTH_USER))
{
Header("WWW-Authenticate: Basic realm=\"My Realm\"");
Header("HTTP/1.0 401 Unauthorized");
echo "Text to send if user hits Cancel button\n";
exit;
}
else
{
if ( !($PHP_AUTH_USER=="tnc" && $PHP_AUTH_PW=="nature") )
{
// 如果是错误的用户名称/密码对，强制再验证
Header("WWW-Authenticate: Basic realm=\"My Realm\"");
Header("HTTP/1.0 401 Unauthorized");
echo "ERROR : $PHP_AUTH_USER/$PHP_AUTH_PW is invalid.";
exit;
}
else
{
echo "Welcome tnc!";
}
?>

沒有任何問題啊
為什麼呢

我還重啟過很多次
還是不行的

把这段程序放到文件首部呢？

我改成了這個樣子：

<?php
header('WWW-Authenticate: Negotiate');
header('WWW-Authenticate: NTLM', false);
?>
<html>
<body>
<body>
</html>

現在在Zend裡面的輸出是：
Status: 401

Content-type: text/html

X-Powered-By: PHP/5.0.0

WWW-Authenticate: Negotiate

WWW-Authenticate: NTLM

<html>
<body>
<body>
</html>

而在自己Apacke上打開的網友上依舊是：
Warning: Cannot modify header information - headers already sent by (output started at D:\Program Files\Apache Group\Apache2\htdocs\zend\index3.php:2) in D:\Program Files\Apache Group\Apache2\htdocs\zend\index3.php on line 3

Warning: Cannot modify header information - headers already sent by (output started at D:\Program Files\Apache Group\Apache2\htdocs\zend\index3.php:2) in D:\Program Files\Apache Group\Apache2\htdocs\zend\index3.php on line 4

正是奇怪了

你的認證是標準的HTTP頭嗎？不像啊？要不直接用meta輸出吧
