composer简介 1 Composer 是 PHP 的一个依赖管理工具。它允许你申明项目所依赖的代码库，它会在你的项目中为你安装他们。
准备工作 1.一个github账号
1.首先在github上创建一个项目 2.把项目克隆到本地 3.进入项目根目录初始化项目 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 ➜ xdpframework git:(master) composer init Welcome to the Composer config generator This command will guide you through creating your composer.json config. Package name (<vendor>/<name>) [shiwenyuan/xdpframework]: Description []: a xdp framework Author [北行10000 <13341007105@163.com>, n to skip]: Minimum Stability []: dev Package Type (e.g. library, project, metapackage, composer-plugin) []: License []: MIT Define your dependencies. Would you like to define your dependencies (require) interactively [yes]? Search for a package: Would you like to define your dev dependencies (require-dev) interactively [yes]? Search for a package: { "name": "shiwenyuan/xdpframework", "description": "a xdp framework", "license": "MIT", "authors": [ { "name": "北行10000", "email": "13341007105@163.com" } ], "minimum-stability": "dev", "require": {} } Do you confirm generation [yes]? Would you like the vendor directory added to your .gitignore [yes]? yes
此时目录下回程车一个composer.json文件，文件内容形如
1 2 3 4 5 6 7 8 9 10 11 12 13 { "name": "shiwenyuan/xdpframework", "description": "a xdp framework", "license": "MIT", "authors": [ { "name": "北行10000", "email": "13341007105@163.com" } ], "minimum-stability": "dev", "require": {} }
4.编写自己的composer包 4.1 此处我创建了一个src目录并实现了SayHello类 1 2 3 4 5 6 ➜ xdpframework git:(master) ✗ tree . ├── README.md ├── composer.json └── src └── SayHello.php
4.2 修改composer.json 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 { "name": "shiwenyuan/xdpframework", "description": "a xdp framework", "license": "MIT", "authors": [ { "name": "北行10000", "email": "13341007105@163.com" } ], "minimum-stability": "dev", "require": {}, "autoload": { "psr-4": { "XdpFrameWork\\": "src/" } } }
4.3 自动加载src目录 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 在4.2添加了src的加载运行composer install实现自动加载 ➜ xdpframework git:(master) ✗ composer install Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files 此时目录中会生成一个vendor 它实现了加载方法 ➜ xdpframework git:(master) ✗ tree . ├── README.md ├── composer.json ├── src │ └── SayHello.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
4.4 测试结果 1 2 3 4 5 6 7 8 9 10 11 12 13 14 创建test.php <?php /** * Created by PhpStorm. * User: shiwenyuan * Date: 2018/8/2 13341007105@163.com * Time: 下午8:56 */ require_once __DIR__."/vendor/autoload.php"; use XdpFrameWork\SayHello; SayHello::world(); 命令行中运行 ➜ xdpframework git:(master) ✗ php test.php hello world
4.5 忽略vendor、composer.json文件 1 2 修改.gitignore增加下面两行 /vendor/
4.6提交代码到 github 5. Packagist配置 5.1 github关联到Packagist 1 2 3 4 5 6 1.首先要在Packagist上登录 2.点击顶部导航条中的Summit按钮 3.在输入框中输入github上的仓库地址，如：https://github.com/shiwenyuan/xdpfarmwork 4.然后点击Check按钮 5.Packagist会去检测此仓库地址的代码是否符合Composer的Package包的要求 6.检测正常的话，会出现Submit按钮，再点击一下Submit按钮，我们的包就提交到Packagist上了
5.2 配置自动同步 1 2 3 1.从Packagist点击个人中心点击profile获取token然后复制 2.到github项目首页上点击settings、点击webhooks、点击addwebhook 3.把https://packagist.org/api/bitbucket?username=USERNAME&apiToken=TOKEN 复制到Payload URL，在下方输入密码后保存
5.3 打tag测试 引用包 1 composer require shiwenyuan/xdpframework
注意事项 1 2 3 如果下载不下来到话就换一下镜像 composer config -g repo.packagist composer https://packagist.laravel-china.org 刚发布上去可能会下载不到，没有同步过来-- 可以等一会在试试看
