最近发现分布式锁在很多项目都有所用到,所以想把之前完成的代码封装成pear包,供大家使用。
但是发现自己对composer并不是很熟悉,所以学习一番,在此记录以防自己忘记。

新建仓库

$ git clone git@gitlab.renrenche.com:web/jugg.git
$ cd jugg

conmposer 初始化

composer init

Would you like to define your dependencies (require) interactively [yes]? yes
Search for a package: php
Enter the version constraint to require (or leave blank to use the latest version):
Using version ^7.0 for php

        }
    ],

}

生成自动加载（psr-4）

在composer.json 文件里添加

    "autoload": {
    "psr-4": {
      "Jugg\\": "jugg"
    }
    },
    "minimum-stability": "dev"
}

执行composer install

就会生成一个自动加载文件

image

然后我们就可以按照psr-4规范开发我们pear包了。

测试

我们可以在测试文件里引入autoload.php文件,这样就实现了自动加载。

1
require './vendor/autoload.php';

这样就可以正常的测试了

上传代码到gitlab或者github

当我们开完的时候,需要将我们的代码上传到远程代码库。

需要注意的事 一定不要讲.git文件上传。

其他项目引入

因为没有上传到pagelist,所以我们暂时是公司私有包。

如果需要再项目里引入私有包,需要在项目的composer.json文件里添加。

然后执行composer require jugg<包名> 就可以引入到项目里了。
