用Json配置文件来驱动Php Laravel框架

把Laravel5.5 的 php配置文件 改为 用json配置文件来驱动

记录一下自己学习过程(简易版未完成)

前因: 吾公司项目是基于 Laravel5.5 开发的、 项目业务的配置比较多，我们有python 和其他 程序。其实配置可以抽出来公共管理的。json 也是一个很好的格式。所以就尝试用 json文件 来驱动Laravel框架运行。把配置文件json化。

源配置文件

先大概截图下过程有空再改

 

这一步是把Laravel默认加载配置驱动配置换成我创建的驱动来完成

 

新建一个目录   \Facades\Facade

创建一个文件。 这是加载json驱动程序代码 （仿照原来加载php的代码改的）

<?php

        // First we will see if we have a cache configuration file. If we do, we'll load
        // the configuration items from that file so that it is very quick. Otherwise
        // we will need to spin through every configuration file and load them all.
        if (file_exists($cached = $app->getCachedConfigPath())) {
            $items = require $cached;

        }

        // Next we will spin through all of the configuration files in the configuration
        // directory and load each one into the repository. This will make all of the
        // options available to the developer for use in various parts of this app.

完成后配置截图 这时候 .php 配置已经没作用了。只是没有删除

数据样子 数据暂时是正则替换 实现 env 配置
