开发 Composer 包详细步骤

匿名 · 更新于 2019/1/30

开发一个 composer 通用文件上传包，发布到 Packagist，并在 Laravel 中测试。

一、GitHub 创建一个名 uploadfile 新仓库，并克隆至本地。

$ git clone git@github.com:guanguans/uploadfile.git
$ cd uploadfile

二、初始化项目，生成composer.json文件

2.1 步骤

yzm@Alert MINGW64 /i/phpstudy/WWW/uploadfile
$ composer init

Welcome to the Composer config generator


This command will guide you through creating your composer.json config.


Package name (<vendor>/<name>) [yzm/try-make-package]: guanguans/uploadfile
Description []: 一个通用文件上传包
Author [guanguans <53222411@qq.com>, n to skip]: guanguans <yzmguanguan@gmail.com>
Minimum Stability []: dev
Package Type (e.g. library, project, metapackage, composer-plugin) []: l                                                                                                    ibrary

"license": "MIT",

Do you confirm generation [yes]? yes

2.2 步骤解释

yzm@Alert MINGW64 /i/phpstudy/WWW/uploadfile
$ composer init

Welcome to the Composer config generator


This command will guide you through creating your composer.json config.


// 1. 输入项目命名空间
// 注意<vendor>/<name> 必须要符合 [a-z0-9_.-]+/[a-z0-9_.-]+
Package name (<vendor>/<name>) [dell/htdocs]: yourname/projectname


// 2. 项目描述
Description []: 这是一个测试


// 3. 输入作者信息，可以直接回车
Author [guanguans <53222411@qq.com>, n to skip]:


// 4. 输入最低稳定版本，stable, RC, beta, alpha, dev
Minimum Stability []: dev


// 5. 输入项目类型，
Package Type (e.g. library, project, metapackage, composer-plugin) []: library


// 6. 输入授权类型
License []:
> Define your dependencies.


// 7. 输入依赖信息
Would you like to define your dependencies (require) interactively [yes]?


// 如果需要依赖，则输入要安装的依赖
Search for a package: php


// 输入版本号
Enter the version constraint to require (or leave blank to use the latest version): >=5.4.0


// 如需多个，则重复以上两个步骤


// 8. 是否需要require-dev，
Would you like to define your dev dependencies (require-dev) interactively [yes]?


// 操作同上
{
"name": "guanguans/uploadfile",
"description": "一个通用文件上传包",
"type": "library",
"require": {
"php": ">=5.4"
},
"require-dev": {
"php": ">=5.4"
},
"license": "MIT",
"authors": [
{
"name": "guanguans",
"email": "yzmguanguan@gmail.com"
}
],
"minimum-stability": "dev"
}


// 9. 是否生成composer.json
Do you confirm generation [yes]? yes

三、添加自动加载

在上一步生成的composer.json中追加

"autoload": {
    "psr-4": {
        "Guanguans\\": "src/"
    }
}

四、构建项目

4.1 新建uploadfile/src/UploadFile.php

├─uploadfile                
│  ├─src                     
│  │  ├─UploadFile.php
│  └─composer.json

<?php
/**
 * 通用文件上传类
 * @author  guanguans <yzmguanguan@gmail.com>
 */
namespace Guanguans;  // 注意命名空间与 composer.json 中的一致

class UploadFile
{
    private $config = [   
        'maxSize'           =>  -1,    // 上传文件的最大值
        'supportMulti'      =>  true,    // 是否支持多文件上传
        'allowExts'         =>  [],    // 允许上传的文件后缀 留空不作后缀检查
        'allowTypes'        =>  [],    // 允许上传的文件类型 留空不做检查
        'thumb'             =>  false,    // 使用对上传图片进行缩略图处理
        'imageClassPath'    =>  'ORG.Util.Image',    // 图库类包路径
        'thumbMaxWidth'     =>  '',// 缩略图最大宽度
        'thumbMaxHeight'    =>  '',// 缩略图最大高度
        'thumbPrefix'       =>  'thumb_',// 缩略图前缀
        'thumbSuffix'       =>  '',
        'thumbPath'         =>  '',// 缩略图保存路径
        'thumbFile'         =>  '',// 缩略图文件名
        'thumbExt'          =>  '',// 缩略图扩展名
        'thumbRemoveOrigin' =>  false,// 是否移除原图
        'thumbType'         =>  1, // 缩略图生成方式 1 按设置大小截取 0 按原图等比例缩略
        'zipImages'         =>  false,// 压缩图片文件上传
        'autoSub'           =>  false,// 启用子目录保存文件
        'subType'           =>  'hash',// 子目录创建方式 可以使用hash date custom
        'subDir'            =>  '', // 子目录名称 subType为custom方式后有效
        'dateFormat'        =>  'Ymd',
        'hashLevel'         =>  1, // hash的目录层次
        'savePath'          =>  '',// 上传文件保存路径
        'autoCheck'         =>  true, // 是否自动检查附件
        'uploadReplace'     =>  false,// 存在同名是否覆盖
        'saveRule'          =>  'uniqid',// 上传文件命名规则
        'hashType'          =>  'md5_file',// 上传文件Hash规则函数名
    ];

4.2 测试

4.2.1 终端下执行 composer install，这时会生成vendor目录，及其他文件

yzm@Alert MINGW64 /i/phpstudy/WWW/uploadfile
$ composer install

4.2.2 新建uploadfile/test/UpploadFileTest.php、uploadfile/test/UpploadFile.html

  • UpploadFileTest.php
<?php

require_once '../vendor/autoload.php';


use Guanguans\UploadFile;


$upload = new UploadFile();
$upload->maxSize       = 110241024;    // 默认为-1，不限制上传大小
$upload->savePath      = './upload/';    // 上传根目录
$upload->saveRule      = 'uniqid';       // 上传文件的文件名保存规则
$upload->uploadReplace = true;           // 如果存在同名文件是否进行覆盖
$upload->autoSub       = true;           // 上传子目录开启
$upload->subType       = 'date';         // 上传子目录命名规则
$upload->allowExts     = ['jpg', 'png']; // 允许类型

if ($upload->upload()) {
var_dump($upload->getUploadFileInfo());
} else {
var_dump($upload->getErrorMsg());
}

  • UpploadFile.html
<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <title>uploadfile test</title>
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
    <form action="UpploadfileTest.php" method="post" enctype="multipart/form-data">
        <div class="form-group">
            <label>单文件上传</label>
            <input type="file" name="uploadfile">
        </div>
        <button type="submit" class="btn btn-primary">Submit</button>
    </form>
    <hr>
    <form action="UpploadfileTest.php" method="post" enctype="multipart/form-data">
        <div class="form-group">
            <label>多文件上传</label>
            <input type="file" name="uploadfile[]">
            <input type="file" name="uploadfile[]">
        </div>
        <button type="submit" class="btn btn-primary">Submit</button>
    </form>
</body>
</html>

4.2.3 本地浏览器访问uploadfile/test/UpploadFile.html进行测试

五、添加 README.md、LICENSE、.gitignore等文件，项目最终结构如下：我的包GitHub地址

├─uploadfile                扩展包根目录
│  ├─src                    扩展包代码目录
│  │  ├─UploadFile.php
│  ├─test                   测试目录
│  │  ├─uploadfile.html
│  │  ├─UpploadfileTest.php
│  ├─.gitignore
│  ├─composer.json
│  ├─LICENSE
│  └─README.md

六、推送到 GitHub

git add .
git commit -m 'init'
git tag v1.0.0 // 记住打一个版本号
git push origin master
git push v1.0.0

七、将 GitHub 上的包提交到 Packagist

  1. 首先要在 Packagist 上注册账号并登录（可以用 GitHub 直接登录）
  2. 点击顶部导航条中的 Summit 按钮
  3. 在输入框中输入 GitHub 上的刚才包地址，如：https://github.com/guanguans/uploadfile
  4. 然后点击 Check 按钮 Packagist 会去检测此仓库地址的代码是否符合 Composer 的 Package 包的要求 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

八、设置 composer 包自动更新

上面提交上的包提交的包，当我们更新 GitHub 仓库时，Packagist 上面的的包并不会自动更新，现在我们来设置一下自动更新

8.1 复制 Profile API Token

8.2 打开 GitHub 项目 setting，选择 Integrations & services，添加 packagist service，点击 Test service

8.3 验证是否已经自动更新

移步 Packagist 包主页，发现已经没有了红色的圈住的提示，说明设置自动更新成功。

九、项目中使用

我以 Laravel 中使用举例

composer create-project laravel/laravel
cd laravel
composer require guanguans/uploadfile

其他
