composer初体验，发布一个简单的composer包

first-composer

第一次尝试写自己的composer

1.在GitHub上创建一个自己的项目，然后拉取到本地

git clone https://github.com/XianglinLiu/first-composer.git

2.在对应的项目目录里面执行composer init

cd first-composer
composer init #一路回车就可

然后可看到生成了文件composer.json

{
    "name": "xianglin/first-composer",
    "description": "this is a test composer",
    "authors": [
        {
            "name": "xianglin",
            "email": "793101759@qq.com"
        }
    ],
    "require": {}
}

3.在根目录新建文件夹src

mkdir src

4.新建测试文件.TestComposer.php 并声明命名空间

<?php
/**
 * Created by YupaoWang
 * User：liubo
 * Date：2020/5/26
 * Time：20:14
 */

namespace firstComposer;

class TestComposer
{
    public function showTime()
    {
        echo '当时北京时间: ' . date('Y-m-d H:i:s');
    }
}

5.修改composer.json 新增autoload

{
  "name": "xianglin/first-composer",
  "description": "this is a test framework",
  "license": "MIT",
  "authors": [
    {
      "name": "xianglin",
      "email": "793101759@qq.com"
    }
  ],
  "autoload": {
    "psr-4": {
      "firstComposer\\": "src/"
    }
  },
  "require": {}
}

6.执行tree 命令可以看到当前目录结构

.
├── README.md
├── composer.json
└── src
    └── TestComposer.php

7.执行composer install ，然后执行tree查看当前目录文件

.
├── README.md
├── composer.json
├── src
│   └── TestComposer.php
└── vendor
    ├── autoload.php
    └── composer
        ├── ClassLoader.php
        ├── LICENSE
        ├── autoload_classmap.php
        ├── autoload_namespaces.php
        ├── autoload_psr4.php
        ├── autoload_real.php
        ├── autoload_static.php
        └── installed.json

8.进行测试，新建测试文件夹exp 新建测试文件index.php

<?php

require_once(__DIR__ . '../../vendor/autoload.php');

use firstComposer\TestComposer;

(new TestComposer())->showTime();

php exp/index.php

输出:当时北京时间: 2020-05-26 12:27:43%

9.编辑文件.gitignore

vim .gitignore
#写入以下数据
/vendor/

10.提交代码到GitHub

git add .  
git commit -m ':rocket: 这个第一次自己写composer 组件'  
git pull && git push

11.检测compser包 packagist.org

12.检测正常，点击提交即可,提交成功将会跳转到已发布包的地址

13.打包命令,我是直接在GitHub上打包的。

    git tag 1.0 
    git push origin --tags

14.测试一下 ,随便建一个文件夹执行命令

composer require xianglin/first-composer

15.写一个测试文件index.php

<?php
require_once('autoload.php');

use firstComposer\TestComposer;

(new TestComposer())->showTime();

php vendor/index.php 
时北京时间: 2020-05-26 12:47:24%
