yii yii2 load automatic

Yii2在项目中使用了composer来管理第三方的类库,Yii呢?就没有这样的目录了。不过在他自己的目录结构里其实有这样目录结构,比如extensions。而且默认是用Yii::import(ext.xxxxx.*);来加载 如果再建一个vendor的目录呢?如果我也要用composer怎么办 呢?Yii

Yii2在项目中使用了composer来管理第三方的类库,Yii呢?就没有这样的目录了。不过在他自己的目录结构里其实有这样目录结构,比如extensions。而且默认是用Yii::import("ext.xxxxx.*");来加载

如果再建一个vendor的目录呢?如果我也要用composer怎么办 呢?Yii的加载是靠类名自动加载的。而它的类名却没有办法认到Vendor目录下的程序。这时候应该怎么办呢?

所以Yii还提供了一个简单的办法:Yii::registerAutoloader(array('Requests', 'autoloader'));

看到这个Requests了没,这个就是第三方的HTTP类库,官网是:http://requests.ryanmccue.info/,这应该是目前PHP中最好的Request的类库了,但默认,它的autoload方式,Yii不支持,所以在Requests.php的第一行加入上面的代码。这回好了,Yii::import("ext.Requests"); 你就可以在任何地方调用:Requests::get($url),而不用担心找不到类了
