composer上发布项目Packgist

• 使用composer创建一个项目的基本流程：
  1.创建 composer.json，并添加依赖到的扩展包；
  2.运行 composer install，安装扩展包并生成 composer.lock；
  3.提交 composer.lock 到代码版本控制器中，如：git;
• 准备：

GitHub帐号
Composer程序(确认你已经安装)
Packagist帐号（用GITHUB账号登录）

• Github
  例如我的项目地址：
  https://github.com/zlqbookGM/house.git
  已经部署到Github上的项目：获取你的项目地址，将项目克隆到本地。
  未部署：将你项目上传到Github上，并获取你这个项目的地址。
• composer本地操作

1. 本地初始化conposer.json
   $ cd ~/path/...
$ composer init
2. 初始化composer文件，推送修改到github，如果你项目在github，这一步刻意忽略。

• packgist

1. 镜像包发布到packgist
   使用Github账户登录Packgist，由于本身composer就是从github发展而来的。
   找到submit，用你的项目仓库地址将镜像包发布提交。

2. 配置GitHub和Packagist之间的自动更新钩子，根据向导，复制自己的packagist的api token，然后去GitHub配置好仓库的钩子服务（此处在测试器，github集成与服务已经逐渐弃用）

• 本地测试与测试安装包
  $ cd ~/work/path/
$ composer require zlqbookGM/hello dev-master
  结果：

D:\phpStudy\PHPTutorial\WWW>composer create-project zlqbook/housespider

Generating autoload files

• 为项目添加outload属性
  psr-4自动加载规范，了解其他加载规范，查询PHP-FIG

    {
        "psr-4": { "Rivsen\\Demo\\": "src" }
    },

看一个具体的composer.json文件：

• Github包版本管理：
  创建一个版本，通过github和packgist链接，更新到Packgist库中。
  版本命名规则：命名方法

/*创建分支*/
$ cd ~/work/github/hello-world
$ git branch
//创建分支 0.1
git checkout -b 0.1
//提交分支
$ git add .
$ git commit -m 'update readme'
$ git push origin 0.1
发布版本
$ git tag 0.1.0
$ git push --tags
