php Laravel 添加自定义类和函数

     我现在的情况是这样的.我只有学生的学号,现在我要用列表展示这些学号,姓名,性别,专业等信息.

当然那些信息是存在的,是在我们的基础库中.我要通过我们自己编写的基础库api进行数据的查询操作.

我需要在我的框架中实现一个CurlHelper的类,然后再使用一个方法进行实例化,因为只有部分页面需要用到这些功能.

那么这该怎么在我的框架中实现呢?

首先我在app目录下建立一个文件夹,名为tools,在里面建立两个文件,

一个叫做CurlHelper.php主要有个CurlHelper的类.

另一个是functions.php  这是程序常用的一些函数存放的地方.

类我就不写了,我这里是说明这样一种情况..

函数还是要写一下,因为最后我们需要在控制器或者 模型中进行调用.

function getCurl(){

static $api = null;

        if(!$api){

            $api = new CurlHelper(//参数);

       }

    return $api;

}

这就是全部的内容.下面我们需要将CurlHelper类引入框架中.

使用 composer dumpautoload  这时就能够通过依赖注入找到这个类了.

至于常用的这些函数,就是在程序加载时就已经放置到内存中去了.

所以我们甚至可以在public/index.php中通过require app_path().'/tools/functions.php';来加载.

这样,我们就可以在控制器中直接调用我们的getCurl()函数来进行类的实例化了.

Knowledge can change your fate and English can accomplish your future.

Best Wishes.
