cakephp-2.0 - CakePHP 控制台给出错误 "Undefined index: HTTP_HOST"

Question

我在 APP/Config/config.php 中有一个设置我有一行定义主机:

define('SITE_URL','http://'.$_SERVER['HTTP_HOST']);

每当我运行蛋糕控制台时，我都会收到错误:

Notice (8): Undefined index: HTTP_HOST [APP/Config/config.php, line 144]
Code Context
include - APP/Config/config.php, line 144

ShellDispatcher::run() - CORE/Cake/Console/ShellDispatcher.php, line 68

为什么会出现这个问题，我该如何解决这个问题？

Answer 1

这是因为您是从控制台运行的，(cakePHP 使用 PHP-CLI)

$_SERVER['HTTP_HOST']

它仅在从浏览器(网络服务器)运行时填充
