容易混淆的几个参数

'HTTP_HOST' => 'www.sxy-admin.com',  // HTTP_HOST = SERVER_NAME:SERVER_PORT，默认80，所以不显示

'DOCUMENT_URI' => '/index.php', // nginx服务有这个参数，有的服务器没有，这个应该不常用
'REQUEST_URI' => '/admin/merchant?username=hxslcc', // 域名根目录下的所有完整路径
'SCRIPT_NAME' => '/index.php', // 脚本相对于根目录下完整路径，不包括其它参数（.php结束）
'REQUEST_METHOD' => 'GET',
'QUERY_STRING' => 'username=hxslcc',
'SCRIPT_FILENAME' => 'D:/UPUPW_NP7.1/htdocs/sxy-admin/public/index.php', // 当前脚本的完整绝对路径

'PHP_SELF' => '/index.php', // 与SCRIPT_NAME 区别于，当index.phph后面带有斜杆/, 返回的会是index.php 后的内容
