Laravel框架中扩展函数、扩展自定义类的方法,laravel框架

一、扩展自己的类

在app/ 下建立目录 libraries\class 

然后myTest.php 类名格式 驼峰 myTest

复制代码 代码如下:


class myTest
{
public  function test()
{
return '1asdasd111';
}
}


在 app/start/global.php

复制代码 代码如下:


ClassLoader::addDirectories(array(
app_path().'/commands',
app_path().'/controllers',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/libraries/class', //增加这一段
));


用 make 载入

复制代码 代码如下:


class HomeController extends BaseController {
    protected $layout = 'layouts.main';
public function index()
{
$a = App::make('mytest'); // 用法
echo $a->test();
}
}

二、扩展自己的函数

在app/ 下建立目录 libraries\function

建立helper.php

函数格式,如下用function_exists,防止与系统重名

复制代码 代码如下:


if (! function_exists('test2'))
{
function test2()
{
echo 2222222222222222;
}
}

方法一:

在 app/filters.php

复制代码 代码如下:


App::before(function($request)
{
require app_path().'/libraries/function/helper.php'; //载入 自定义函数
});

方法二:

在app/bootstrap/autolad.php

复制代码 代码如下:


require __DIR__.'/../app/functions.php'; // 引入自定义函数库

我感觉方法一会比较好。

怎引用自定义dll的类函数或者方法

default.aspx的代码:


sq s = new sq();
.........
.........
%>

如果在default.aspx.cs文件下引用DLL:
先在项目引用下添加shangqi.dll引用,然后在代码里加上using shangqi;

这样就OK了、、、
 

Python怎调用自定义类中的函数?

你好:
你要在自定义的函数里面的第一个参数设置为:
self
这是python约定的;
调用的时候可以不用管它,它相当于this!
