本地测试环境中

apahche httpd-vhosts.conf 中添加虚拟主机例如 test.demo.com

增加变量

SetEnv CI_ENV "development"

本地hosts文件 增加对应 ip 如127.0.0.1 test.demo.com

CI application config 文件夹中 config.php文件

添加以下信息
switch (ENVIRONMENT)
{
case \'development\':
$config[\'base_url\'] = \'test.demo.com\';
break;
case \'production\':
$config[\'base_url\'] = \'www.demo.com\';
break;
}

数据库对应设置 以sae为例

CI application config 文件夹中 database.php文件

switch (ENVIRONMENT)
{
case \'development\':
$db[\'default\'] = array(
\'dsn\' => \'\',

/**** localhost ***/
