我想打开我的网站的登录页面只有https,而不是comeplete网站.登录验证(成功)后,网站再次在http上运行.

目前我的主要登录页面是test_index.PHP,其中包括test_header.PHP

我在test_header.PHP上的基本代码是

if($_SERVER['SERVER_PORT'] != 443) {
   header("HTTP/1.1 301 Moved PErmanently");
   header("Location: https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
   exIT();
}

但这使得完整的网站在https
 我也读了here,它可以通过.htaccess,所以我从test_header.PHP删除上面的代码片段并在.htaccess文件中添加以下行

<IfModule mod_rewrite.c>
  RewriteEngine on
  # 301 redirect to domain to 'www.'
  RewriteCond %{HTTP_HOST} ^testweb.COM$[NC]
  rewriterule ^(.*)$http://www.testweb.com/$1 [R=301,L]
</IfModule>

<FilESMatch test_index.PHP>
RewriteEngine on
RewriteCond %{HTTPS} !=on
RewriteRule .* https://%{SERVER_NamE}%{REQUEST_URI} [R,L]
</FilesMatch>

注意：testweb.com只是一个虚构的名称,而不是实际的网站

但仍然完整的网站运行https,请告诉我我在哪里做错了？

编辑

@webbiedave请检查我更新的代码,是正确的方法??

if ($_SERVER['REQUEST_URI'] == '/test_index.PHP') { // only check https on LOGin
    if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
        header("HTTP/1.1 301 Moved Permanently");
        header("Location: https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
        exit();
    } else {
        die("Sorry,Your website is not secure");        
    }
} elseif (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
        // header("HTTP/1.1 301 Moved Permanently");
        header("Location: http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
        exit();
}

谢谢

if ($_SERVER['REQUEST_URI'] == '/login.PHP') { // only check https on login
    if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
        // do login stuff
    } else {
        // redirect to https or simply give an error
    }
} elseif (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
    // redirect to http
}
