How can I add external class in Laravel 5
提问by Hamed Kamrava
There is a class in app/Libraries/TestClass.phpwith following content:
有一堂课，app/Libraries/TestClass.php内容如下：
class TestClass {
public function getInfo() {
return 'test';
}
}
Now, I would like to call getInfo()method from this external class in my Controller.
现在，我想getInfo()从我的控制器中的这个外部类调用方法。
How can I do such thing?
我怎么能做这样的事情？

First you should make sure that this class is in the right namespace. The correct namespace here would be:
首先，您应该确保此类位于正确的命名空间中。这里正确的命名空间是：
namespace App\Libraries;
class TestClass {
Then you can just use it like any other class:
然后你可以像其他任何类一样使用它：
$test = new TestClass();
echo $test->getInfo();
Don't forget the import at the top of the class you want to use it in:
不要忘记在您要在其中使用它的类顶部的导入：
use App\Libraries\TestClass;
In case you don't have control over the namespace or don't want to change it, add an entry to classmapin your composer.json:
如果您无法控制命名空间或不想更改它，请classmap在您的composer.json:
"autoload": {
"classmap": [
"app/Libraries"
]
}
Then run composer dump-autoload. After that you'll be able to use it the same way as above except with a different (or no) namespace.
然后运行composer dump-autoload。之后，您将能够以与上述相同的方式使用它，但使用不同的（或没有）命名空间。
