2014.1.1 晚首发与SAE开发者论坛
相信大家也都或多或少的了解过Laravel框架吧,本人以前是使用CodeIgniter框架的,2012年接触到了当时候的Laravel 3,立马就被它吸引了,关于它的介绍,我在这里不做详谈,感兴趣的可以到其官网查看了解.
对于SAE来说,云环境的一些限制让我们无法很直接自由的使用L4,先来看几点核心的:
- SAE限制了本地文件读写,L4对于一些缓存(如manifest)是采用了本地写的。
- 缓存类,L4并没有直接提供SAE可直接使用的缓存类。
- Session类,L4的Native Session并不是PHP的原生Session,用到了本地文件写,所以不可以行,这点可以结合缓存类进行解决。
- SAE默认session_start(),而使用了Symfony Session的L4,自然继承了seesion类和自动session_start冲突的问题。
- 模版引擎,依然是本地文件写的问题.
那么,想要在SAE上使用L4,那么必须解决以上几个问题。
幸运的是,PHP5的新特性和L4强大的扩展能力使得我们可以轻松解决上述问题。
这里我写了个项目,可以让您的L4项目优雅的本地开发和运行与SAE平台。
本文不会详细介绍如何改造,感兴趣的可以直接去看源代码,本文说明一下,如何改造本地项目,做到本地开发和SAE线上运行无痛切换。
本地项目开发改造:

$app['aliases']['Storage'] = 'Lavender\Cloud\Sina\Storage\Storage';
$app['sae'] = true;
}
return $app;
只要在判断是SAE环境下的时候注入相应的类取代L4自带的类。
'mysql' => array(
'driver' => 'mysql',
'host' => SAE_MYSQL_HOST_M,
'database' => SAE_MYSQL_DB,
'username' => SAE_MYSQL_USER,
'password' => SAE_MYSQL_PASS,
'charset' => 'utf8',
'collation' => 'utf8_general_ci',
'prefix' => '',
),
使用SAE数据库设置常量配置我们的数据库设置。
'driver' => 'memcache',
使用提供的memcache驱动。
L4支持自定义开发环境,一般本地开发就是local配置啦,这里可以在bootstrap/start.php中设置。
然后我们在app/config/local文件夹下配置本地开发环境配置。
经过以上配置,我们搭建了本地开发和SAE运行环境的配置分离。
然后就是尽情开发啦~~~~~~~~~
这里需要整个项目打包上传,推荐使用SAE的SVN上传。
L4使用的包中,有涉及到直接修改php.ini的操作,这个东西会导致程序直接抛错。
不用担心,上传之前只需执行:
php artisan sae:patch
一切都变得美好了。
做个小宣传,也是我的运行SAE上的L4的程序,当个DEMO吧~~
